Fannie & Freddie’s New Appraisal Rules Put Pressure on Accuracy — Here’s Why Permit Data Is Your Secret Weapon

May 8, 2025 by Farrah Jochai Leave a Comment

How building permit intelligence helps lenders, appraisers, and AMCs meet the demands of GSE appraisal modernization

Overview

Fannie Mae and Freddie Mac are overhauling the appraisal process. With the introduction of the Uniform Appraisal Dataset (UAD) 3.6 and expanded eligibility for appraisal alternatives, the focus on data accuracy and transparency has never been greater. Lenders and appraisers must now navigate a landscape where precise property data is paramount.

In this context, building permit data emerges as a critical asset. It offers verified insights into property improvements, ensuring that appraisals reflect true property conditions. BuildZoom, with its extensive permit database, stands at the forefront, providing the tools necessary to meet these new appraisal standards.

The New Appraisal Landscape: UAD 3.6 and Beyond

The Federal Housing Finance Agency (FHFA) has initiated significant changes to appraisal practices:

  • UAD 3.6 Implementation: Starting September 8, 2025, lenders can begin using the updated Uniform Appraisal Dataset, with full adoption expected by January 26, 2026. This update aims to enhance data consistency and appraisal quality.
  • Expanded Appraisal Waivers: Fannie Mae has increased the loan-to-value (LTV) ratio eligibility for appraisal waivers from 80% to 90% for certain purchase loans, emphasizing the need for accurate property data to support these decisions.
  • Hybrid Appraisals: Both GSEs are promoting hybrid appraisals, combining third-party property data collection with desktop appraisals, necessitating reliable data sources to ensure accuracy.

The Challenge: Ensuring Data Accuracy

These changes place a premium on accurate, verifiable property information. Traditional data sources may not capture recent renovations or unpermitted additions, leading to potential inaccuracies in property valuations. This gap can result in compliance issues, loan buybacks, or misinformed lending decisions.

The Solution: Leveraging Permit Data

Building permit data provides a reliable record of property improvements, offering:

  • Verification of Property Changes: Confirming that renovations or additions were permitted and inspected.
  • Insight into Property Condition: Understanding the scope and quality of improvements.
  • Enhanced Risk Assessment: Identifying properties with unpermitted work that may pose risks.

By integrating permit data into the appraisal process, stakeholders can ensure more accurate valuations and compliance with GSE requirements.
