Fannie Mae Guidelines: High-Balance Loan Pricing and Insurance

What Makes High-Balance Loans More Expensive

High-balance loans cost more than conforming loans because Fannie Mae charges additional loan-level price adjustments (LLPAs) on every high-balance transaction. These fees get built into your interest rate or paid as upfront costs.

Say you're buying a $900,000 home in San Francisco with 10% down. Your $810,000 loan amount exceeds the 2024 conforming loan limit of $766,550 for that area, making it a high-balance loan. You'll pay the standard LLPAs based on your credit score, down payment, and loan type, plus the additional high-balance adjustment.

The high-balance LLPA applies whether your lender sells the loan directly to Fannie Mae as a whole loan or packages it into a mortgage-backed security. All price adjustments stack on top of each other — there's no cap or maximum.

Mortgage Insurance Requirements for High-Balance Loans

If you put down less than 20%, you'll need mortgage insurance on a high-balance loan just like any other conventional loan. The insurance protects Fannie Mae if you default.

You can finance the mortgage insurance premium into your loan amount, but there's a catch. Your total loan-to-value ratio after adding the financed premium cannot exceed 95%. This creates a practical limit on how much premium you can finance.

Here's how this works: You're buying a $800,000 home with 5% down, creating a $760,000 base loan amount and a 95% LTV. If the mortgage insurance premium is $7,600 (1% of the loan amount), financing it would create a $767,600 total loan and push your LTV to 95.95%. That exceeds the 95% maximum, so you'd need to pay the premium upfront or find a different solution.

Special Reporting Requirements

Your lender must tag high-balance loans with special feature code 808 when delivering them to Fannie Mae. This code tells Fannie Mae's systems to apply the correct pricing and handle the loan properly.

The lender also reports any other applicable special feature codes based on your loan's characteristics. For example, if you're using the loan for an investment property, that gets its own code in addition to the high-balance designation.

Government loans like FHA and VA mortgages don't use the 808 code because they follow different rules and aren't subject to Fannie Mae's high-balance requirements.

Delivery Limitations and Pooling Restrictions

High-balance loans face the same delivery limitations as other nonstandard loan products. Fannie Mae limits how many of these loans lenders can deliver in certain time periods to manage risk concentration.

When lenders package high-balance loans into mortgage-backed securities, they must follow specific pooling rules outlined in [[C3-2-01]] and [[C2-2-01]]. These rules ensure the securities meet investor requirements and maintain proper diversification.

However, high-balance loans can be included in Fannie Majors pools, which are larger, more liquid securities that trade more easily in the secondary market. This gives lenders more flexibility in how they sell these loans.

Why These Rules Exist

Fannie Mae treats high-balance loans differently because they represent larger dollar amounts and potentially higher risk. The additional pricing adjustments compensate for this increased exposure.

The mortgage insurance requirements mirror those for conforming loans because the risk of default doesn't change based on loan size — a borrower with minimal equity is still more likely to default regardless of whether they borrowed $400,000 or $800,000.

The delivery limitations help Fannie Mae manage its overall portfolio risk by preventing any single lender from delivering too many high-balance loans at once. This protects against concentration risk in expensive housing markets.

Common Issues and Complications

The 95% maximum LTV with financed mortgage insurance catches many borrowers off guard. If you're planning to finance your mortgage insurance premium, calculate the total LTV carefully before committing to a loan amount.

Some borrowers assume high-balance loans follow different underwriting standards, but they don't. You'll face the same income, asset, and credit requirements as any other conventional loan. The only differences are pricing and insurance rules.

Lenders sometimes struggle with the special feature code requirements, particularly when loans have multiple characteristics that require different codes. Missing or incorrect codes can delay loan delivery and cause pricing problems.

In markets where home prices fluctuate near the conforming loan limits, a property appraisal that comes in higher or lower than expected can push your loan from conforming to high-balance or vice versa, changing your pricing and requirements mid-process.
