Appraisers warn private real estate listings limit data for accurate appraisals

HousingWire reported that starting November 2, 2026, appraisers must comply with UAD 3.6, which mandates selecting detailed property data from dropdown menus rather than using text descriptions.

Appraisers rely heavily on Multiple Listing Service (MLS) data, including photos and historical pricing, to verify comparable sales and assess property conditions, according to HousingWire.

However, the rise of private listings and restrictions on MLS photo usage are creating data scarcity, making it difficult for appraisers to access necessary information, said Virginia-based appraiser Desiree Mehbod.

Mehbod noted that when interior photos and floor plans are removed immediately after a sale, appraisers are left without critical details, which hinders transparency and accuracy in appraisals.

This issue arises amid growing concerns about data privacy among consumers and real estate professionals, who sometimes encourage private listings to avoid public records of price adjustments or days on market.

HousingWire highlighted that these changes affect not only agents and brokers but also appraisers, who must now provide more granular data in their reports despite limited access to MLS information.
