How FHFA Calculates the Annual Adjustment
Each year, FHFA compares the national average home price from the third quarter of the current year to the third quarter of the prior year using the FHFA House Price Index, which tracks purchase prices on properties with conforming mortgages. The percentage change in the index determines the percentage adjustment to the baseline conforming limit. If the HPI shows a 5.2% increase in average home prices, the baseline limit increases by 5.2% (rounded to the nearest $50 increment ). Because the limit is tied to a national average, it does not directly reflect local market conditions; individual counties may experience price changes very different from the national average. The high-cost area mechanism addresses this by allowing county-specific limits above the baseline where local median values warrant it. FHFA publishes the new limits in late November of each year, and the updated limits take effect on January 1 of the following year for loans with application dates on or after that date.
How High-Cost Area Limits Are Determined
For counties in designated high-cost areas, FHFA calculates the local loan limit as 115% of the county’s median home value, capped at 150% of the baseline national limit. This meansUnder the FHFA's HERA-based methodology, a county's conforming limit is set at 115% of the local area median home value, capped at 150% of the national baseline; for 2026, a ceiling of $1,249,125 for single-unit properties A county with a median home value of $1,200,000 would have a calculated limit of $1,380,000, but because this exceeds the ceiling, the county limit is capped at $1,209,750. Under special statutory provisions in HERA, Alaska, Hawaii, Guam, and the U.S. Virgin Islands automatically receive conforming limits set at the national ceiling: $1,249,125 for single-unit properties in 2026 The list of high-cost counties and their specific limits is published by FHFA alongside the baseline announcement. The highest county limits are concentrated in states like California, New York, and New Jersey, where median home values in many counties exceed the baseline limit.
How FHA Floor and Ceiling Limits Work
FHA’s floor-and-ceiling structure ensures a minimum loan limit in every county regardless of local home prices. The floor is set at 65% of the conforming baseline limit. In 2025, this means The minimum FHA limit for any county in 2026 is approximately $541,288, calculated as 65% of the FHFA’s $832,750 baseline conforming limit In counties where median home values support a higher limit, FHA calculates the limit using a similar methodology to FHFA’s conforming calculation. The FHA ceiling matches the conforming high-cost ceiling at $1,209,750 . This floor-ceiling structure means FHA limits are always at or below the corresponding conforming limit for a given county, which can make conventional loans a better fit for borrowers needing loan amounts above the FHA limit but below the conforming limit.
How VA Entitlement and County Limits Interact for Partial Entitlement
For VA borrowers with full entitlement, there is no loan limit and no interaction with county limits. For borrowers with partial entitlement, the VA county limit (which mirrors the conforming limit) determines the maximum guaranty. For borrowers with partial entitlement, the VA calculates the maximum guaranty as 25% of the county conforming loan limit, as detailed in VA Pamphlet 26-7 (Chapter 3) and 38 U.S.C. 3703. Since the veteran has only $100,000 of entitlement remaining, the VA can guarantee up to $100,000. Lenders typically require VA borrowers to have guaranty coverage equal to 25% of the loan amount; if the remaining entitlement does not provide this coverage, the veteran must make a down payment to cover the shortfall. The calculation is: Down payment = 25% of (loan amount minus the VA guaranty coverage available). This calculation can result in modest or significant down payment requirements depending on the gap between the veteran’s remaining entitlement and the desired loan amount.
Multi-Unit Property Limits
Conforming and FHA loan limits increase for properties with two, three, or four units, reflecting the higher purchase prices typical of multi-unit residential buildings. The 2025 conforming limits for multi-unit properties at the baseline level are approximately: For 2026, FHFA baseline conforming limits for multi-unit properties are $1,066,250 for two units, $1,288,800 for three units, and $1,601,750 for four units High-cost area limits for multi-unit properties are calculated using the same 150% ceiling methodology. Borrowers purchasing a duplex, triplex, or fourplex as an owner-occupied primary residence can access these higher limits, which is a significant advantage for house-hackers and small-scale real estate investors who occupy one unit while renting the others.
