Consequences of Nondisclosure State Home Sales on Property Taxes

In the United States, private home sales in nondisclosure states allow sale prices to remain confidential, raising concerns about fairness in property tax assessments. Experts highlight that missing sale price information can result in lower property taxes for some homeowners, potentially shifting the burden to neighbors.

Impact on Property Assessments

Usually, home sales data is crucial for assessing property values and determining tax bills. In nondisclosure states, where sellers’ privacy is prioritized, this information lacks transparency. As a result, experts warn that those with access to private sale information might leverage it to secure lower tax bills.

According to Assaf Harpaz, Assistant Professor at the University of Georgia School of Law, jurisdictions rely on various data points for property assessments. He noted that sales conducted off the market introduce transparency issues, potentially affecting the accuracy of assessments.

Challenges for Tax Assessors

Private listings, legal nationwide and regulated by the National Association of Realtors (NAR), differ by state in terms of public record. Nondisclosure states keep sale prices confidential, creating information asymmetries between off-market and public sales. Harpaz pointed out that actors with superior access to market data could contest assessments based on private knowledge.

Real estate researcher Sergio Garate, from Emory University, explored these issues in his study. He found that private listings in nondisclosure states result in tax assessors relying on alternative data like prior assessments and comparable sales. This scarcity of information leads to valuation errors and potentially benefits some homeowners.

Real-Life Implications

Garate’s research indicates that property owners are unlikely to contest assessments that undervalue their homes. This creates an imbalance, particularly in nondisclosure states where assessment inaccuracies can lead to lower property tax bills.

The information discrepancy between disclosure and nondisclosure states affects appraisals and mortgage performance. Garate’s study reveals appraisal bias and higher mortgage default rates, particularly among financially constrained borrowers.

Transaction dynamics, including volume and bargaining power, may also shift due to information asymmetries. In New Mexico, which moved from full nondisclosure to partial disclosure in 2004, tax revenue increased by 4 percent annually, highlighting the revenue impact of nondisclosure laws.

Property tax structures aim to generate a certain revenue. If nondisclosure leads to assessments below true market value, the tax burden may shift to other properties. This situation emphasizes the need for a review of nondisclosure practices in property sales and their potential impact on tax fairness.
