How AI Home Valuations Are Impacting Appraisals

If you’re hoping to refinance your mortgage, you’ve probably checked your home’s value using online tools found on real estate websites.

These AI-powered tools can generate price estimates in minutes, bypassing the need for a licensed appraiser and an in-person inspection. However, as AI algorithms play a larger role in how homes are appraised and lending decisions are made, some homeowners question their accuracy.

To avoid costly mistakes, homeowners and borrowers should understand how AI valuations work, how to interpret these estimates, and how they could affect their refinancing opportunities.

What are AI-powered home valuation tools?

Automated valuation models use AI to analyze large datasets and produce property value estimates. These models efficiently sift through comparable sales data, tax assessments, lot size, square footage, satellite images, neighborhood metrics, and pricing trends to gauge a property’s market value.

Valuation tools like those available to consumers on real estate platforms provide estimates based on publicly available data, while some lenders may utilize institutional AVMs that incorporate proprietary data and advanced risk modeling.

It’s easy to see how AI-powered models enhance the appraisal process. Automated appraisals are faster, typically cost less, and are more efficient. Additionally, AI scrutinizes enormous amounts of data and teases out broad patterns while also learning from fluctuating market conditions. Overall, AI-supported valuations help standardize the lending process by providing more consistent results.

More lenders are using AVMs to determine an applicant’s loan eligibility, assign appraisal waivers in low-risk refinance situations, and streamline the approval process, all of which have the potential to save homeowners and borrowers time and money.

Hybrid appraisals

AI’s use in refinancing has not completely replaced the traditional appraisal process, but it is transforming it.

Many lenders are moving to hybrid models, an option that requires a trained third-party property collector to gather data on the property. The data is then reviewed remotely by a licensed appraiser, who incorporates AI-supported analysis to develop an opinion on a property’s condition and value.

Other “desktop appraisal” models may have limited or no physical inspection, relying solely on AI-driven technology to arrive at a valuation.

Some real estate professionals view the use of AI in the appraisal process as a positive for the industry. AI-driven property valuations are quick and efficient, allowing lenders to simplify workflows and approve loans with faster turnaround times. Additionally, AI continuously incorporates new, updated market data into its analyses, which some professionals say supports consistency and fairness across markets.

Other professionals point out that AI cannot replace human expertise when it comes to assessing a home’s upgrades, renovations, structural issues, or providing insight into a neighborhood’s nuances. AI is only as accurate as the data it synthesizes, and some experts caution against an overdependence on algorithms when it comes to complex or individual markets.

Are AI valuations accurate?

It’s understandable that homeowners may question how fair and accurate AI-generated algorithms are when appraising their homes. AI systems are commonly criticized for being “black boxes” when it comes to transparency, and borrowers or lenders may not be clear on what data was used or how it was analyzed to arrive at a valuation.

Although AI’s thoroughness can potentially reduce subjective human bias, it can unintentionally reflect systemic bias present in historical records, which AI relies upon for its analyses. Neighborhoods that were subjected to discriminatory practices, such as redlining or undervaluation, may still suffer from lower valuations regardless of the current market climate because of an AI model’s analysis of outdated patterns.

In neighborhoods with high sales volume, similar housing stock, and consistent pricing trends, data is usually plentiful and up to date. In these environments, AI is typically able to provide accurate estimates with small margins of error. AI struggles, however, in rural or low-volume markets, volatile markets, or markets with renovated homes that are not accurately depicted in public records.

How AI can affect your refinancing

Lenders use AVMs to determine your loan-to-value ratio, and even small variations in valuation can affect your interest rate or whether you’ll need to pay private mortgage insurance.

If an AI tool reflects your home value accurately, you may be eligible for favorable mortgage interest rates, an appraisal waiver, or a home equity line of credit, depending on what type of loan you’re applying for and your borrower profile.

If an AI-generated algorithm undervalues your home, uses outdated data, or is unable to interpret volatility in your market, you could be denied a lower mortgage rate or a large loan amount.

It’s important to remember that although AI valuations are highly informed estimates, they’re not free from error and shouldn’t be interpreted as the final word on your home’s value.

What borrowers should know before refinancing

For homeowners starting the refinancing process, online estimates are a starting point, not an absolute.

Consult multiple AVMs to compare and contrast the findings. AI is only as good as the data inputs, so ensure your home’s details (such as the number of bedrooms, bathrooms, and square footage) are accurate.

Don’t hesitate to ask your lender questions about the extent to which AI was used in your valuation. Also, ask your lender to explain what happens if your home’s valuation changes during the underwriting process because of market fluctuations.

Ask if you can request a full in-person appraisal if you disagree with the valuation. In some circumstances, it may be better to consult a professional from the start. If your home is unique, historic, or recently renovated, a traditional in-person appraisal may work to your advantage.

Takeaway

The use of AI-powered tools in property valuation will continue to expand, bringing consistency, speed, and insights that streamline the mortgage process. Human appraisers will continue to bring context, local expertise, and nuanced evaluations that can’t be replicated by a computer model.

For homeowners, the key is understanding the role and limitations of AI tools in the refinance process so they can be confident that decisions affecting their home’s value are not merely the result of an algorithm.
