Understanding Conforming Loan Limits
Every year, the Federal Housing Finance Agency (FHFA) sets the maximum loan amount that Fannie Mae and Freddie Mac can purchase from lenders. This ceiling is called the conforming loan limit, and it determines whether your mortgage qualifies for standard conventional pricing or requires a jumbo loan. For 2025, the standard limit for a single-family home is $806,500 โ up from $766,550 in 2024.
The limit matters because loans within the conforming boundary get sold to Fannie Mae or Freddie Mac, which creates liquidity in the mortgage market and keeps rates competitive. Loans above the limit cannot be sold to these agencies, forcing lenders to hold them on their own books โ which typically means stricter qualification standards and higher interest rates. For a deeper overview of how this fits into the broader conventional landscape, see our conforming loan guide.
Standard Conforming Limits by Property Type
The conforming limit scales with the number of units in the property. Conventional loans allow financing for 1-to-4 unit properties (with owner-occupancy requirements for multi-unit), and each unit count has its own ceiling. These limits apply to most areas of the country โ the baseline floor that FHFA sets nationally.
Limit applies to loan amount, not purchase price
A common misconception: the conforming limit caps your loan amount, not the home's price. If you purchase a $900,000 home and put 15% down ($135,000), your loan amount is $765,000 โ well within the $806,500 limit. A larger down payment can keep you in conforming territory even on higher-priced properties.
High-Cost Area Limits: Up to $1,209,750
In areas where median home prices exceed the standard conforming limit, FHFA allows higher ceilings โ up to 150% of the baseline. For 2025, that means the high-cost ceiling for a single-family home is $1,209,750. These elevated limits are county-specific, with FHFA publishing the exact number for each county based on local median home values.
Loans between the standard limit ($806,500) and the high-cost ceiling ($1,209,750) are sometimes called high-balance conforming loans or super-conforming loans. They carry slightly higher rates than standard conforming โ typically 0.125% to 0.250% more โ but significantly better terms than true jumbo loans because they're still backed by Fannie Mae or Freddie Mac.

Multi-Unit Conforming Limits: 2025 Complete Table
Multi-unit properties (2โ4 units) have proportionally higher conforming limits because the purchase prices are naturally higher. Conventional allows financing up to 4 units as long as the borrower occupies one unit as a primary residence. This is a popular strategy for house-hacking โ living in one unit while renting the others to offset mortgage costs.

The Role of Fannie Mae & Freddie Mac
Fannie Mae (Federal National Mortgage Association) and Freddie Mac (Federal Home Loan Mortgage Corporation) are government-sponsored enterprises that buy mortgages from lenders, package them into mortgage-backed securities, and sell them to investors. This secondary market is what keeps mortgage rates lower than they'd be if each lender had to hold every loan on its own balance sheet.
The conforming limit exists because of this structure. Fannie and Freddie can only purchase loans that meet their guidelines โ including the maximum loan amount. When a loan exceeds the limit, it can't be sold to these agencies, which fundamentally changes the economics for the lender. This is why jumbo loans behave differently: the lender retains the risk, so they demand higher credit scores, larger reserves, and charge higher rates to compensate.
How limits are adjusted annually
FHFA adjusts the conforming limit each year based on changes in the national average home price. When home prices rise, the limit increases to keep pace. The 2025 increase to $806,500 reflects a 5.2% rise from 2024's $766,550. FHFA uses Q3 home price data from its own House Price Index to calculate the adjustment, with new limits announced in late November and taking effect January 1.
What Happens When Your Loan Exceeds the Limit
Once your loan amount exceeds the applicable conforming limit for your area (standard or high-cost), you're in jumbo loan territory. Jumbo mortgages are not backed by Fannie Mae or Freddie Mac, which means the lender takes on more risk โ and passes that risk along to you in the form of tighter requirements and different pricing.
