Fannie Mae Guidelines: USDA RD-Guaranteed Mortgages

What Are RD-Guaranteed Mortgages

USDA Rural Development Section 502 guaranteed mortgages help moderate-income borrowers buy homes in eligible rural areas. These government-backed loans offer competitive interest rates and flexible underwriting terms. Fannie Mae purchases these loans from lenders, providing liquidity to support rural homeownership.

The loans must be secured by one-unit residential properties in USDA-eligible rural areas. This includes single-family homes, manufactured homes permanently affixed to foundations, and some townhomes. The property must be the borrower's primary residence.

Interest Rate Buydowns and Qualification Requirements

Some RD loans include interest rate buydowns that reduce the borrower's payment in early years. The buydown might lower the rate by 2% in year one, 1% in year two, then revert to the full note rate in year three.

Even with a buydown, the borrower must qualify at the full note rate. Say a borrower gets a 6% loan with a 2-1 buydown. They'll pay 4% in year one and 5% in year two, but the lender must verify they can afford the 6% payment from day one.

This qualification requirement protects borrowers from payment shock when the buydown expires. It also ensures the loan meets Fannie Mae's ability-to-repay standards.

Higher Balance Loan Limits

RD loans traditionally had lower loan limits than conventional mortgages. But Fannie Mae now accepts higher balance RD loans up to the same limits that apply to conventional loans in high-cost areas.

In 2024, the baseline conforming loan limit is $766,550. In expensive markets like San Francisco or Manhattan, the limit can reach $1,149,825. RD borrowers in these areas can now access these higher limits while keeping the benefits of government backing.

The property must still be in a USDA-eligible rural area. Some high-cost metropolitan areas have pockets of rural-designated land where these higher limits apply.

Section 502 Leveraged (Blended) Loan Program

This program combines two loans: a conventional first mortgage sold to Fannie Mae and a direct RD second mortgage with a subsidized interest rate. The structure helps borrowers with limited down payment funds access homeownership.

The first mortgage follows all standard Fannie Mae guidelines for conventional loans. The borrower might put down 3% and get a first mortgage for 94% of the home's value. The RD second mortgage covers the remaining 3% at a below-market rate, sometimes as low as 1%.

Fannie Mae only purchases the first mortgage. The RD second mortgage stays with the government. This arrangement gives borrowers the benefit of Fannie Mae's competitive rates on the larger loan while getting subsidized financing for the smaller portion.

Lenders don't need special approval from Fannie Mae to originate these loans. Any Fannie Mae-approved lender that meets RD's eligibility criteria can participate. The loans fall under Fannie Mae's Community Seconds program guidelines found in [[B5-5.1-02]].

Required Documentation and Delivery Codes

When delivering RD loans to Fannie Mae, lenders must use specific feature codes in their loan delivery system. A standard Section 502 guaranteed loan requires code 087. If the property is a manufactured home, add code 235.

For Leveraged (Blended) loans, use codes 118 and 220. These codes tell Fannie Mae's systems that a Community Seconds loan is involved and trigger the appropriate pricing and servicing setup.

All Section 502 loans are assumable, meaning a qualified buyer can take over the loan when the property sells. The loan delivery application must show "True" for the Assumption Indicator. This preserves the loan's assumability for future buyers.

Common Issues and Complications

Property eligibility can trip up borrowers and lenders. USDA's rural designation doesn't always match common sense. Some areas that feel suburban are still considered rural, while others that seem rural have lost their eligibility due to population growth.

Income limits add another layer of complexity. RD loans have area-specific income limits based on median income. A family might qualify in one county but not in a neighboring county with higher incomes. These limits can change annually.

Manufactured homes require extra attention to foundation and HUD code requirements. The home must be permanently affixed to a foundation and meet specific construction standards. Some older manufactured homes don't qualify even if they're in good condition.

For Leveraged (Blended) loans, timing coordination between the two loan closings can create challenges. Both the conventional first mortgage and the RD second mortgage must close simultaneously. Any delays in RD processing can hold up the entire transaction.

Processing and Underwriting Considerations

RD loans follow Fannie Mae's standard underwriting guidelines with some government program overlays. Debt-to-income ratios, credit score requirements, and asset verification all apply as they would for conventional loans.

The main difference is the additional RD approval process. Borrowers must meet USDA's income and property eligibility requirements before the loan can proceed. This adds time to the approval process compared to conventional loans.

Lenders should verify the property's continued USDA eligibility early in the process. Rural designations can change, and a property that was eligible last year might not qualify today. The USDA website provides current eligibility maps, but calling the local RD office provides the most reliable confirmation.

For Leveraged (Blended) loans, the combined loan-to-value ratio can reach 100% or more when including both mortgages. The first mortgage alone must meet Fannie Mae's LTV requirements, but the combined financing can exceed these limits with the RD second mortgage.
