- High-cost area loan limits increase to $1,249,125, 150% of baseline.

The Federal Housing Finance Agency announced that for 2026, the baseline conforming loan limit for single-family homes will increase to $832,750, up 3.25% from $806,500 in 2025. In high-cost areas, limits will rise to $1,249,125, set at 150% of the baseline, ensuring that Fannie Mae and Freddie Mac can continue to support the housing market effectively (FHFA announcement).
Fannie Mae updated its Selling Guide to integrate VantageScore 4.0 credit scores, effective April 22, 2026, marking a modernization effort to provide a more comprehensive borrower credit assessment. This initiative aims to create a more competitive and resilient mortgage finance system, as highlighted by Jake Williamson, EVP at Fannie Mae (Fannie Mae credit score update). The adoption of the newer FICO Score 10T is planned but not yet scheduled.
Starting March 18, 2026, updated condo project standards and property insurance requirements will apply to one-to-four-unit properties and developments, reflecting adjustments aligned with current market risks (Fannie Mae project standards update).
Additionally, the FHFA finalized new affordable housing goals for 2026–2028 to promote middle-class homeownership nationwide (FHFA affordable housing goals), continuing federal efforts to balance housing accessibility with regulatory oversight.
For legal teams and compliance professionals working with mortgage lenders and borrowers, these changes mean adjusting operational processes and ensuring alignment with evolving regulatory frameworks. Stakeholders must prepare for the implementation deadlines and integrate new credit score criteria and property standards into their lending practices.
By the numbers:
- $832,750 — baseline conforming loan limit for one-unit properties in 2026
- $1,249,125 — loan limit for one-unit properties in high-cost areas in 2026
- 3.25% — increase in baseline conforming loan limit from 2025 to 2026
Yes, but: Details about the timeline for implementing FICO Score 10T remain unspecified, limiting full readiness for credit score modernization.
What's next: Watch for the March 18, 2026 implementation of updated condo project and property insurance standards, and April 22, 2026 introduction of VantageScore 4.0 credit scoring.
