The court determined there was a triable issue of fact regarding the Taits' actual loss. The ruling emphasized the importance of considering the highest and best use in determining property value under title insurance policies.2026-01-27 17:14:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-139-investigating-the-property-value-impacts-of-the-east-palestine-train-derailmentThe investigation concluded that residential property values in the affected VAP area dropped by approximately 14% compared to control properties following the derailment. Specifically, the regression models indicated a 12.8% discount for homes anywhere in the VAP, while properties located outside the evacuation zone but within the VAP saw discounts of up to 15.8%. Beyond price diminution, the study found a significant impact on market liquidity: homes in the affected area sold roughly 26% slower, averaging about 11.5 additional days on the market, than those in unaffected areas. These findings aligned with the CV survey results, which estimated value losses between 17% and 28% for the top quarter of the market and suggested that nearly 40% to 50% of potential buyers would refuse to make an offer on impacted homes altogether.2025-12-29 17:21:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-138-how-is-technology-transforming-real-estateWe read these studies with the CARCA lens in mind, completeness and adequacy of data, reliance, credibility, and appropriateness of data, analysis, and conclusion. None of them gives us a universal fifteen percent or ten percent adjustment to plug into every assignment. They show mechanisms and orders of magnitude, not discount tables. Digital tools can help us see patterns faster and link parcels to risk data more clearly, but they do not replace market research, local knowledge, or a transparent narrative about how buyers and sellers in this market, at this time, are actually responding.2025-10-28 18:38:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-137-tree-coverage-and-property-values-in-san-antonio-texasIn urban neighborhoods, both low and high tree canopy coverage can decrease property values, while in suburban neighborhoods, more tree canopy, especially at the neighborhood level, significantly increases property values. For instance, in the highest-value area, low property specific tree canopy combined with low neighborhood tree canopy can reduce property values by up to 8%, whereas high neighborhood canopy can boost values by 4-6%.2025-09-25 19:07:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-136-groundwater-contamination-and-its-impact-on-florida-real-estate-copyProperty Value Diminution: Homes with detectable contaminants in their well water experienced an 8% to 10% reduction in property values. Long-Term Market Resistance (Stigma): Contaminants detected up to 10 years before a sale still negatively impacted property values. ​ Price Rebound: Homes with contaminant levels exceeding federal or state standards (aboveSTD) showed a potential price rebound of 10% to 19.1%, but this rebound was statistically insignificant.2025-08-21 19:51:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-135-nationwide-pipeline-incidents-and-property-valuesPipeline incidents have a notable impact on nearby housing prices, reducing them by an average of 4% to 6%. A more precise model estimates a 6.1% decline within 90 days of an incident, which is statistically significant at the 5% level. This translates to substantial housing value losses over the decade, amounting to $10 billion to $14 billion, equivalent to 1.4% of total U.S. housing transactions in 2014, based on an average pre-incident home price of $175,728. Incidents with greater public attention, such as explosions (14.5% price drop), ignitions (8.3%), or evacuations (7.6%), cause more significant declines.2024-11-14 19:29:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-134-perceived-risk-and-uncertaintyThe findings suggest that the explosion significantly altered how buyers, especially housing developers, assessed the risks of purchasing land near chemical industrial parks. As public awareness of these risks increased, particularly in areas with higher media coverage, the price drops became more pronounced. The effect on land prices was short-term, disappearing within two to four years after the event. This study emphasizes how industrial accidents can reshape public risk perceptions and, in turn, influence economic behavior in real estate markets across a nation.2024-11-14 19:24:00https://www.strategicpropertyanalytics.com/blog/atomic-energy-sustainability-versus-resuscitating-shuttered-sitesIn economics, the long run and short run differ in how easily resources can be adjusted. In the short run, factors are fixed, while in the long run, all factors—such as changing energy sources or plant size—can be modified. In a competitive market, organizations can adjust their plant size over the long run to respond to changes in demand and prices.The possibility of restarting facilities like Three Mile Island or Palisades prompts critical reflections on the future of energy in an increasingly climate-conscious world. While nuclear power could serve as a short-term remedy to rising energy demands, its long-term sustainability remains questionable in light of the growing potential of renewable energy sources. To create a resilient and environmentally responsible energy infrastructure, we must consider adopting a balanced approach that thoughtfully assesses the risks and benefits of nuclear energy alongside sustainable alternatives. By prioritizing a diverse energy portfolio, we may ensure a more secure and sustainable future for generations to come.2024-11-14 19:20:00https://www.strategicpropertyanalytics.com/blog/don-t-forget-to-flossIn "Navigating PFAS Risk and its Persistent Impact on Emerging Laws and Liability" (2024), attorneys Adam Sanders and Ryan Freeman deliver an in-depth analysis of the evolving legal and regulatory landscape surrounding PFAS (2). These chemicals have become a critical issue due to their widespread use in consumer products and their alarming environmental and public health impacts. The authors trace the history of PFAS, from their development by 3M and DuPont in the mid-20th century to their current notoriety as a public health concern.2024-11-14 19:18:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-129-evolving-urban-planning-conceptsThe article suggests that while the 15-minute city is a promising approach to urban planning, there are still many challenges to implementing it effectively. These include ensuring equity in access to services, preventing gentrification, and adapting the model to different urban contexts. The authors call for more research and real-world examples to understand better the strengths and weaknesses of their concept. They argue that while the idea offers a compelling vision for the future of cities, its success will depend on how well it integrates with other urban planning strategies and how it addresses the diverse needs of urban populations.2024-11-14 19:16:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-127-remote-work-impacts-on-real-estate-valuesAs remote work becomes more prevalent, the demand for physical office spaces has diminished. Companies that once needed substantial office space are now reducing their real estate footprints, leading to a decrease in both rental rates and property values in commercial real estate markets. This trend is particularly evident in urban areas that were previously bustling with office workers. The decline in demand for commercial real estate in these major cities raises concerns about their future economic vitality.2024-09-25 18:27:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-126-how-do-the-olympic-games-impact-your-home-s-valueHis findings reveal significant disparities in housing market outcomes. According to Kontokosta's analysis, Barcelona and Sydney experienced substantial increases in housing prices following their respective Olympic Games. In contrast, Los Angeles, Calgary, and Atlanta witnessed negative effects on housing prices, while Seoul showed no major change. These results indicate that the economic benefits of hosting the Olympics are not uniformly distributed and can sometimes lead to adverse outcomes.2024-07-29 16:46:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-124-how-do-flood-hazards-on-the-carolina-coast-influence-real-estate-valuesA study conducted by Okmyung Bin and Jamie Brown Kruse gives insight to the question posed in the header title above. Their hedonic study looks at how flood risks affect house prices in Carteret County, North Carolina, a coastal area with flood-prone regions. Their research focuses specifically on coastal flood hazards between various flood zones. The authors cited other studies that found that flood risk lowers property values inland by 3% to 12%, the high premiums paid for coastal properties make flood insurance premiums less influential in overall market pricing. Using flood maps and property sales data from 2000 to 2004, Bin and Kruse found that when a property is located within a flood zone that is not subject to coastal wave action the property values are 5% to 10% lower. Properties in flood zones that face wave action have higher values due to their proximity to the water.2024-05-13 17:08:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-123-investigating-the-impact-of-industrial-chemical-accidents-on-single-family-property-values-in-ohio-pennsylvania-and-michiganOn average, accidents did not exert a significant influence on SFR property values. However, incidents resulting in adverse health effects, pollution of the environment, evacuations, or directives to seek refuge in place precipitated a discernible decline in the value of residences within a five-kilometer radius, ranging from 5% to 7%. This equated to an average reduction in property values ranging from $12,000 to $17,000. Individual buyers and sellers of properties in nearby housing markets exhibited heightened awareness regarding incidents with offsite effects compared to those solely involving onsite effects. Moreover, residences within two kilometers of a solitary RMP facility, regardless of any releases, tended to experience a property value diminution ranging from 2% to 4%, overall, on balance. Collectively, proximity to multiple RMP facilities increased the diminution, with residences within a kilometer of three RMP facilities experiencing a decrease in value exceeding 12% and those within 1 to 2 kilometers experiencing a 5% reduction.2024-04-09 16:47:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-122-exploring-the-impact-of-proximity-to-electrical-transmission-corridors-on-property-values-in-salt-lake-county-utahThe study's findings reveal significant effects on property values attributed to proximity to certain types of electrical transmission lines, which can vary based on geographic location. Notably, homes near 138 kV and 46 kV lines experienced statistically significant decreases in value, while those near 345 kV lines exhibited no negative impact and, in some cases, even show a slight positive effect.2024-03-13 18:16:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-121-investigating-the-influence-of-fracking-transmission-line-facilities-on-property-values-in-new-jersey-and-pennsylvaniaFirstly, similar to existing literature on pipeline proximity, the data from compressor station case studies suggest no consistent adverse impact on nearby home prices. Prices per square foot for homes closest to the pipelines varied, sometimes even exceeding those at greater distances, emphasizing the need for location-specific analysis. Secondly, incidents such as fires or emissions at compressor stations did not necessarily lead to decreased nearby home prices across all studies, with some cases showing inconclusive results. Thirdly, when impacts on home prices did occur due to compressor station incidents, they tended to be temporary, lasting from a few months to a few years before returning to pre-incident levels.2024-02-19 21:01:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-119-a-study-of-wildfire-impacts-on-property-values-in-australiaThe findings reveal that properties within the BPA are generally valued higher than those outside, in line with previous literature emphasizing the positive impact of environmental amenities on real estate prices (Cuculiza et al., 2021). However, following major wildfire events, properties within the BPA experience price decreases of approximately 0.9%–1.7% compared to properties outside the BPA, with the negative impact being significant in the first two years post-event and diminishing thereafter. Additionally, properties within the BPA with higher natural environmental amenities exhibit greater resilience to wildfire risk, indicating the importance of considering environmental factors in wildfire risk research within the housing market context.2024-01-29 21:18:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-118-a-study-of-high-voltage-transmission-line-impacts-on-residential-prices-in-wisconsinResults show that age and the number of bathrooms are the only features reliably predicted by the model, with the HVTL easement not significantly impacting price. The statistical analysis, accounting for emotional factors in home buying, reveals that properties with the easement sold for up to 4.22 percent less than those without, consistent with similar studies.2023-10-09 20:50:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-117-a-study-of-wildfire-impacts-on-unburned-homes-in-coloradoHedonic property models, including both linear and semi-logarithmic approaches, have observed a significant drop in property prices in nearby Pine, a town located 2 miles away from a major wildfire. Property prices in this neighboring community, which was not directly burned by the fire, saw a decline of roughly 15%. This suggests that both prospective buyers and sellers changed their perceptions of fire risk, following the occurrence of this major fire event. Furthermore, the author suggests this adjustment in perception may also signal a potential decrease in the overall desirability of residing within a forested area, ultimately leading to a decrease in property prices2023-09-13 17:09:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-116-a-study-of-pcb-remediation-impacts-on-residential-prices-in-wisconsinThe research findings suggest that property values near the upper Milwaukee River increased after the cleanup efforts, particularly following reductions in PCB concentrations. Considering all residences in the remediated zone, the suggested increase in property value following cleanup amounts to 3%, or $5,683. However, it's important to note that the effects observed primarily pertain to the upper Milwaukee River, and the full restoration of the broader Milwaukee Estuary AOC is still a work in progress. Further research is necessary to confirm the value of fully restoring AOCs based on post-cleanup sales data.2023-09-06 18:56:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-115-a-study-of-lead-risk-zone-impacts-on-residential-prices-in-marylandIrwin’s hedonic output presented evidence that elevated lead risk had a significant negative impact on property values. In 2005, the year following the implementation of the new policy for lead-risk classification, homes in the high lead-risk zones sold for approximately 6.7% less as compared to homes outside of a zone. This estimate increased to 7.9% and 8.9% in the subsequent years.2023-08-15 20:53:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-114-a-study-of-vapor-intrusion-impacts-on-residential-values-across-the-united-statesThe findings reveal notable diversity in the impacts on property prices across different sites; however, the overall trend indicates a decline of 3% to 6% following the public awareness of a release and a subsequent increase of 4% to 9% post-completion of cleanup efforts. These averaged effects encompass the property price responses observed within a 5-year timeframe after the release or the cleanup, and these effects gradually wane as distance from the site increases, extending up to 2 or 3 kilometers away. The authors expressed the view that the implementation of the meta-analysis was judiciously executed within this research, maintaining uniformity across models. This deliberate approach was adopted with the intention of mitigating significant downfalls observed across other studies.2023-08-07 21:56:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-113-a-study-on-natural-landscape-views-and-their-effects-on-residential-property-values-in-missouriThe results of the property fixed-effect model revealed that proximity to green space had a positive impact on property values. However, the impact of different types of natural landscape views varied. Farmland views were considered amenities, as a 2% increase in property prices was observed when the farmland viewshed area increased by 10%. On the other hand, views of green space did not show any statistically significant impact on property values. One of the most intriguing findings of the study was related to views of forestland. Contrary to the assumption that natural landscape views are always beneficial, the study found that views of forestland had a small but statistically significant negative impact on property values.2023-08-03 17:41:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-112-a-study-of-the-boil-water-notices-bwns-and-impacts-on-residential-values-in-west-virginiaThe research findings revealed that boil water notices had varied impacts on real estate values. For properties within the lower 60 percent quantile, BWNs were found to have a statistically significant negative effect on residential values. Moreover, for properties that experienced both a BWN and a one-day water disruption, a decrease in property value was observed ranging from 0.6% to 8.4%. However, for high-priced houses falling within the 0.7 quantile, no noticeable decrease in property value was detected due to BWNs. Overall, the authors concluded that since most properties in the county experienced multiple water disruptions caused by BWNs, residential values were likely to have declined by approximately 1% to 10%. The findings imply that BWNs can have a detrimental effect on property values, particularly for lower-priced houses.2023-07-24 19:27:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-111-a-study-of-racial-bias-impacts-on-real-estate-appraisals-in-the-united-statesRemarkably, the study's findings indicated that there was no significant evidence of racial bias affecting appraised values when comparing black-owned homes to white-owned homes. Based on their thorough analysis, the authors concluded that racial bias did not seem to play a significant role in influencing appraised values in this specific refinance market.2023-07-17 17:47:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-109-a-study-of-innocent-landowner-programs-in-texas-and-arizonaThe case studies demonstrated that innocent landowner programs positively affected property values. Properties within these programs maintained their values similar to unimpaired properties, indicating no diminution in value for non-source properties with a formal release of liability. The Innocent Landowner Program proved beneficial to property owners, preserving their property's value despite previous contamination issues.2023-07-17 17:42:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-108-a-study-of-covid-19-impacts-on-residential-real-estate-prices-in-new-york-cityThe study found that areas with high Covid-19 case rates had a negative impact on the prices of single-family residences, as evidenced by hedonic modeling. Additionally, there was a significant negative correlation between residential sale volume and coronavirus case rates. Specifically, for every 1,000 increase in positive case rates in a particular zip code, single family homes experienced a 10% property value diminution (PVD).2023-06-14 20:46:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-107-a-study-of-drinking-water-contamination-impacts-on-residential-prices-in-santa-clara-county-californiaThe primary purpose of the repeat sales analysis was to quantify the impact on property values before and after the public became aware of the contamination issue. The findings revealed that the unregulated perchlorate contamination provided significant property value diminution to residential property values near the Olin Corporation Facility in California. The repeat sales approach demonstrated a property value diminution (PVD) of 21.82% for homes not affected directly by the contamination source.2023-06-05 17:07:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-106-a-study-of-the-superfund-impacts-on-land-values-in-north-carolinaThe results derived from the hedonic analysis provided evidence of significant decreases in land values associated with shallow-flow groundwater contamination. In contrast, land values remained largely unaffected by deep-flowing contaminated groundwater. The OLS models demonstrated that properties predicted to have groundwater contamination based on geographic and topographic factors experienced a Property Value Diminution (PVD) of 17.55%. Additionally, land values of properties adjacent to contaminated water wells exhibited a PVD of 54%. The authors also acknowledged that their analysis may not completely account for the financial impacts of property contamination for parcels that have become unmarketable due to actual contamination or the potential risk of contamination.2023-03-31 15:43:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-105-a-study-of-the-impacts-from-pipeline-explosions-on-residential-values-in-californiaThe difference-in-differences regression model's initial output showed that buyers of single-family residential homes located 2000 and 1000 feet away from existing natural gas pipelines were willing to pay 1% to 3% less, respectively, after the explosion. However, the authors noted that it was challenging to determine whether the impacts were due to perceived or actual risks. Other model specifications did not reveal any significant impact on property values. In conclusion, the study suggested that pipeline risk can have a negative impact on housing market capitalization.2023-03-20 18:41:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-104-a-study-of-the-impacts-of-pipeline-explosions-on-residential-values-in-bellingham-washingtonBefore the explosion, residential properties had no statistically significant impacts from pipeline proximity for both the Trans Mountain and Olympic pipelines. After the explosion, the Olympic pipeline provided a statistically significant discount for single-family properties located near the pipeline. For homes 50 feet, 100 feet, 200 feet, and 1,000 feet away from the pipeline, the indicated discounts were 4.6%, 2.3%, 1.2%, and 0.2%, respectively. Upon further analysis, the authors observed that the Trans Mountain pipeline had no statistically significant impact after the explosion.2023-01-30 22:56:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-103-a-study-of-the-impacts-from-contamination-on-land-prices-in-baltimore-marylandThe results of the hedonic analysis showed that land with market awareness of documented contamination sold at an average 67% discount compared to unimpaired prices. Properties adjacent to a contamination source experienced a 42% diminution to land value. The study suggested that unconfirmed, presumed environmental source sites can also have impacted property prices. In this study, suspected contamination source sites had property prices 65% lower than unimpaired land value2022-12-07 10:05:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-102-a-study-of-light-rail-transit-system-impacts-on-property-values-in-minnesotaThe hedonic modeling provided evidence that single-family properties near a blue line and a proposed green line station benefited in the magnitude of 5.7% to 6.8%. After development, proximity to a station was found to be an amenity for both lines. Conversely, homes located near a railway without a station experience a decline in property values, with homes near the green line experiencing diminution five times greater when compared to blue line properties. For multifamily properties, model specifications were poor, and thus no conclusion could be made. Similarly, in terms of “value benefit transfer”, an 18% difference was observed. However, no conclusion could be made due to a lack of precision.2022-11-30 23:14:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-101-a-study-of-odor-noise-and-eminent-domain-in-arizonaGiven that the existing facility produced odor, the incremental impact of the expansion was stated to be small. In reconciliation, the appraiser concluded an overall diminution of 4% for the buildable area of the subject property. For industrial use, the impact was stated to be negative but less than residential in magnitude.2022-10-13 21:27:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-99-a-study-of-surface-and-groundwater-contamination-impacts-on-residential-prices-in-buncombe-county-north-carolinaBefore public awareness, properties within the potentially contaminated shallow groundwater plume garnered a 242% premium compared to similar unimpaired properties. After public attention, the premium dissipated completely. After listing on the NPL, the hedonic output revealed a considerable discount for properties within the shallow groundwater plume. A 69% to 77% diminution in value was observed for properties within the shallow groundwater plume. [2] Properties potentially impacted by deep groundwater and surface water contamination did not experience any statistically significant property value diminution in this study.2022-08-30 00:18:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-98-how-does-affordable-housing-affect-property-value-and-crime-rates-in-orange-county-californiaThe results of this study suggest that affordable housing positively affects housing prices and crime rates decrease or essentially stay the same after affordable housing developments are opened. This conclusion contradicts commonly held beliefs about the effects of affordable housing and it is hoped that the study will encourage the development of affordable housing in Orange County.2022-07-29 09:09:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-97-a-study-of-environmental-disclosure-impacts-on-residential-prices-in-washington-county-minnesotaThe hedonic output revealed coefficients of -3% for contaminated homes without GAC filters and -2.3% for homes within the SWCA during the period from 1995 to 2002. However, only the variable for contaminated homes without GAC filters was significant at the 10% significance level. For homes that sold from 2003 to 2006, after the disclosure requirement was enacted, a 7.4% statistically significant diminution in value was observed for homes within the SWCA. In the after-disclosure period, the coefficient for contaminated homes without GAC filters was not statistically significant.2022-06-16 00:00:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-96-a-study-of-airport-and-flight-path-impacts-on-residential-prices-in-raleigh-north-carolinaThe regression output confirmed that airplane noise had statistically significant negative impact to SFR sale prices in Raleigh. For example, homes located within the 65–70 Ldn noise contour, sold for 5.1% less than unimpaired homes (control area transactions) within the one-mile control group area. Furthermore, homes within the 55–60 Ldn noise contour sold for 2.3% less than unimpaired homes.2022-06-15 21:59:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-95-a-study-of-lead-based-paint-remediation-and-influences-on-residential-prices-in-charlotte-north-carolinaBillings and Schnepel’s hedonic output presented evidence that lead-paint remediation had a sizeable positive impact to property values. Furthermore, lead remediated homes sold for approximately $26,270 (32%) more than un-remediated homes. When the authors controlled for home improvements associated with remediation, the estimated benefit dropped to $11,629, and equated to a 160% return on investment for remediation costs.2022-04-01 22:04:00https://www.strategicpropertyanalytics.com/blog/looking-under-the-hood-94-a-study-of-wildfire-impacts-on-residential-prices-in-montanaThe hedonic output offered evidence that wildfires provided a negative impact to property values within 10 KM from a burned area. For homes located within 5 KM from a burned area, a 13.7% ($33,232) diminution in value was observed as compared to unimpaired homes. This damage estimate decreased to 7.6% ($18,924) for homes located within 5 to 10 KM from a burned area. Furthermore, the binary variable for view of a burned area revealed an additional $6,600 diminution.
