Real estate valuations have traditionally leaned heavily on historical data as one of the most important factors used to determine the appraised value of homes. This data includes comparable transactions and cap rates from prior years, along with historical real estate market data. However, there are a few areas that the past-anchored valuation system fails to build into the appraisals, leaving an appraisal gap that is becoming difficult to ignore in 2026.
Major Climate Events
An important lesson that has been discovered more recently in the real estate industry is that not all properties in climate-impacted or high-volatility markets fit standard comps. This means that the insurance industry has had to make adjustments around forward-looking models that factor in major climate events like flooding and wildfires.
- As a result of recent climate incidents, many insurers have pulled out of high-risk markets, and transaction volume has dwindled.
- As a result, appraisers are left using fewer, older comps that are outdated and don’t reflect the current market conditions.
The AVM Issue
The latest technology in real estate has pushed lenders towards Automated Valuation Models (AVMs) as a faster appraisal tool. However, AVMs are another factor contributing to the 2026 appraisal gap problem.
- While these models help lenders speed up their loan processing, the accuracy of AVMs is not flawless when the underlying data is sparse or outdated.
Fewer Comparable Properties
For several years, mortgage rates have been elevated and constraining the market. This has meant that comp volume has been lower than pre-pandemic times.
- Less transaction data means less data for appraisals.
- This also means that the appraisal data is a little less accurate, increasing the likelihood of an appraisal gap.
Geographic Impact
According to the NAR, one of the defining factors impacting the market in 2026 is geographic shifts. Markets with newer homes are slowing down in areas that were once bustling, while other markets are strengthening.
- When it comes to a national appraisal model, there’s no way to account for all these local nuances, so geography has become one of the most important variables in the appraisal gap equation.
The Appraisal Gap in 2026
While appraisal gaps are nothing new, 2026 is showing us a different version of them. Traditionally, appraisals would come in below the contract price in busy markets, but in 2026, appraisals are coming in higher than the contract price.
- Statistics show that only around 10% of home appraisals are below the asking price.
How Originators Can Weather the Appraisal Storm
The effect of appraisal gaps on loans is longer lock-up periods, more extensions, more renegotiations, and ultimately a higher rate of deals falling through. To stay ahead of this, originators need to consider a few solutions for managing appraisal gaps as the second quarter of 2026 begins.
- Start by building the appraisal gap into the loan structure from the beginning.
- Develop an internal appraisal risk score to sort deals into low, medium, and high appraisal risk off the bat.
Conclusion
Climatic volatility, geographic divergence, thin comp pools, and the limits of automated modeling have all landed at the same time. The appraisal gap in 2026 reflects an older version of the market, and a pivot is required. Lenders who build the appraisal risk at the front end of their loan process will be better prepared for future gaps.
