Fannie Mae Guidelines: High-Balance Mortgage Eligibility

What Makes a Loan High-Balance

A high-balance loan sits in the middle ground between standard conforming loans and jumbo loans. The Federal Housing Finance Agency sets these limits annually based on local housing costs.

For 2024, the baseline conforming loan limit is $766,550 for most areas. But in expensive markets like San Francisco, Los Angeles, or parts of New York, the high-balance limit can reach $1,149,825. Your loan becomes "high-balance" when it exceeds the baseline limit but stays under your county's specific high-cost limit.

Say you're buying a home in Orange County, California, where the high-balance limit is $1,149,825. A $900,000 loan would be high-balance because it exceeds the $766,550 baseline but stays under the county limit.

Stricter Requirements You'll Face

High-balance loans come with tighter restrictions than standard conforming loans. The most significant difference is the loan-to-value ratio limits.

For a standard conforming loan, you might qualify with as little as 3% down on a purchase. But high-balance loans typically require larger down payments. The exact LTV limits depend on your credit score, debt-to-income ratio, and other risk factors, all determined through DU.

You cannot manually underwrite a high-balance loan. Every application must run through Fannie Mae's automated underwriting system. This means your loan officer cannot override DU's decision with compensating factors the way they might on a standard loan.

Geographic Limitations Matter

Not every property qualifies for high-balance financing. The home must sit in a county designated as a high-cost area by the Federal Housing Finance Agency.

Fannie Mae provides a Loan Limit Geocoder tool that lets lenders check the exact limit for any address. This matters because limits can vary significantly even within the same metropolitan area.

Consider the Washington DC area. A property in Arlington County, Virginia might qualify for a $970,800 high-balance loan, while a similar property across the river in Prince George's County, Maryland might only qualify for the baseline $766,550 limit.

Documentation Requirements

High-balance loans follow the same documentation standards as other Fannie Mae loans, with one key difference: everything must satisfy DU's requirements.

You'll need the standard package:

• Two years of tax returns and W-2s
• Recent pay stubs covering 30 days
• Two months of bank statements for all accounts
• Verification of employment
• Credit report from all three bureaus

But DU might require additional documentation based on your specific situation. If you're self-employed, expect to provide business tax returns and possibly profit-and-loss statements. If you have rental income, you'll need lease agreements and possibly tax Schedule E forms.

Why These Rules Exist

Fannie Mae treats high-balance loans as riskier than standard conforming loans because they involve larger dollar amounts in expensive markets. These markets often experience more price volatility, creating greater potential losses if borrowers default.

The automated underwriting requirement ensures consistent risk assessment. DU evaluates multiple risk factors simultaneously — your credit score, income stability, debt ratios, down payment, and property characteristics — to determine if the loan meets Fannie Mae's risk tolerance.

The geographic restrictions reflect economic reality. High-cost areas typically have higher incomes but also higher living costs and more volatile real estate markets. Fannie Mae needs these elevated loan limits to serve these markets while managing the additional risk.

Common Complications

The biggest surprise for many borrowers is discovering their desired loan amount exceeds their county's high-balance limit. This forces them into the jumbo loan market, which typically means higher interest rates and stricter qualification requirements.

Credit score requirements can be more stringent than expected. While Fannie Mae publishes minimum credit scores for standard loans, high-balance loans often require higher scores to achieve the same LTV ratios.

Cash-out refinances face additional restrictions. High-balance cash-out refinances have lower maximum LTV ratios than rate-and-term refinances, limiting how much equity you can access.

Some lenders avoid high-balance loans entirely because of the additional complexity and risk. This can limit your shopping options compared to standard conforming loans.

Special Refinance Options

High-balance loans are eligible for Fannie Mae's High LTV Refinance program, which allows refinancing up to 97% loan-to-value in some cases. This program has its own set of eligibility requirements that can override some high-balance restrictions.

The High LTV program requires that your current loan be owned or guaranteed by Fannie Mae or Freddie Mac. You'll need to verify this through the agencies' loan lookup tools before applying.
