What Makes Government Loans Different
Government mortgage loans — FHA, VA, USDA Rural Development, and HUD — operate under a dual set of rules. They must meet the requirements of their respective government agency plus Fannie Mae's overlay requirements when sold to Fannie Mae.
Say you're getting an FHA loan. Your lender must follow all FHA guidelines for approval and underwriting. But if that lender plans to sell your loan to Fannie Mae, they also need to meet Fannie Mae's additional requirements on top of FHA's rules.
This creates a layered approval process. You might qualify under FHA guidelines but still get denied if the loan doesn't meet Fannie Mae's standards. Most lenders price this risk into their decision-making from the start.
Credit Score Requirements You Need to Know
Fannie Mae requires a minimum representative credit score of 620 for all government loans. This applies even if the government agency allows lower scores.
For example, FHA technically allows credit scores as low as 500 with a 10% down payment, or 580 with 3.5% down. But if your lender plans to sell to Fannie Mae, you'll need at least 620 regardless of FHA's more flexible standards.
The one exception is manually underwritten loans with nontraditional credit. These loans can go below 620 if the borrower has no traditional credit history and the underwriter manually reviews alternative credit sources like rent and utility payments.
Timing Restrictions That Could Trip You Up
Government loans have strict age limits. Your loan must be delivered to Fannie Mae within six months of your first payment date. This "freshness" requirement prevents lenders from sitting on loans too long.
Here's how this could affect you: If your lender originates your loan in January with a February 1st first payment date, they must deliver it to Fannie Mae by August 1st. If they miss this deadline, Fannie Mae won't purchase the loan.
Most lenders deliver loans much faster than six months, but this rule can create problems if there are documentation issues or delays in the sale process.
Property and Lien Requirements
Your government loan must be secured by a first lien on the property. This means no other loans can have priority over your mortgage, except for property taxes and special assessments that aren't yet due.
If you're buying a rental property, any existing leases need special attention. Leases that existed before your mortgage was recorded might have superior rights to your lender's interest. Your lender must review each lease to ensure tenants have waived any rights to purchase the property or other rights that could hurt the lender's position.
The lender must also verify that current property taxes and assessments are paid or that sufficient funds are being collected in escrow to pay them.
Documentation Requirements
When your lender delivers a government loan to Fannie Mae, they must provide specific data elements and documentation. This includes the Section of the Act under which the loan was made and government-specific feature codes.
Your lender must also report the transfer of your loan to the appropriate government agency if required. For VA loans, this means notifying the VA. For FHA loans, reporting to HUD.
The payment calculation on your loan documents must match Fannie Mae's calculation within $1.00. While lenders can use different amortization tables, the final payment amounts need to align closely.
Why These Rules Exist
Fannie Mae's overlay requirements exist because they're purchasing loans from lenders and need consistent standards across their portfolio. Government agencies focus on helping borrowers access homeownership, while Fannie Mae focuses on managing investment risk.
The six-month age limit ensures loans are current and reduces the risk of borrower circumstances changing between origination and purchase. The credit score floor provides a baseline risk standard even when government programs are more flexible.
The separate pooling requirement for government loans reflects their different risk characteristics and government backing compared to conventional loans.
Common Issues That Cause Problems
The biggest surprise for borrowers is the credit score requirement. Many people research FHA or VA loan requirements and see lower credit score minimums, only to discover their lender requires 620 because they sell to Fannie Mae.
Rental property purchases can get complicated if existing leases weren't properly reviewed. A lease that gives tenants purchase rights or other superior claims can make the loan ineligible for Fannie Mae purchase.
Payment calculation discrepancies, while seemingly minor, can delay or prevent loan delivery. Even a $2 difference between the lender's calculation and Fannie Mae's can cause issues.
Some lenders need special variances in their contracts with Fannie Mae to deliver government loans. If your lender doesn't have this variance, they can't sell government loans to Fannie Mae at all, which might affect their willingness to originate them.

B6-1-01, General Government Mortgage Loan Requirements (07/05/2023)
Overview
All eligible government mortgage loans purchased or securitized by Fannie Mae must comply with the requirements of the respective government agency. Those loans must also comply with Fannie Mae requirements for government mortgage loans as specifically addressed in this Selling Guide.
Lender Eligibility
Most government mortgage loans can only be delivered to Fannie Mae under a variance in the Lender Contract.
Mortgage Term
The term of a government mortgage loan may not extend more than 30 years beyond the date of the first monthly payment.
Age of Loans
All government mortgage loans must be no more than six months old measured from the first payment date to the "Purchase Ready" date (whole loan) or the MBS pool issue date (MBS loan).
Lien Requirements
The security instrument for a government mortgage loan must be a first lien on the borrower’s real property. The security property may be subject only to liens for taxes and special assessments that are not yet due and payable and to conditions, restrictions, and encumbrances that Fannie Mae does not consider as material. The lender must provide documentation to show that the current installments of taxes and assessments (including those that may have been attached as prior liens, but are not now in arrears) have been paid or that sufficient deposits are being collected to pay them.
Rental Property Leases
When the property that secures the mortgage is rented, the rental agreement or lease may not include any provision that could affect significantly Fannie Mae’s position as mortgagee. In some jurisdictions, leases that predate the mortgage have a superior claim to the mortgage even if they have not been recorded. Normally, a tenant’s rights under a pre-existing lease remain intact on the sale of the leased premises. Accordingly, if the lease is not subordinate to the mortgage, the lender must review each lease to ensure that any tenant’s rights to purchase the property, and any other rights that could affect adversely the mortgagee’s interest, have been waived formally by the tenant or tenants.
Mortgages Permitting Open-End Advances
Fannie Mae will purchase or securitize a government mortgage loan that includes an open-end advance provision only if the provision gives Fannie Mae the option not to make any advances. If funds were advanced prior to delivery, the transaction is considered a modified mortgage that is not eligible for delivery. See B2-1.5-02, Loan Eligibility.
Mortgage Payments
Because Fannie Mae will not decline delivery submissions for slight differences in payment calculations, the lender may use any widely accepted amortization table or formula. However, the monthly payment provided as part of the delivery data and the one that Fannie Mae calculates cannot differ by more than $1.00.
Notice of Transfer
When lenders deliver government mortgage loans to Fannie Mae for purchase or securitization, they must report the transfer of the loan in accordance with the applicable agency’s requirements, if applicable.
MBS Pool Parameters
Government mortgage loans (for example, FHA-insured, VA-guaranteed, HUD-guaranteed, and RD-guaranteed) that are securitized must be pooled in government-prefix MBS pools. Government mortgage loans cannot be commingled in the same pool with conventional mortgage loans.
Remittance Types
For all government mortgage loans, the actual/actual remittance type is required for whole loans. The scheduled/scheduled remittance type is required for all government mortgage loans delivered into MBS. (Lenders should refer to Fannie Mae’s whole loan committing application for additional information regarding eligible whole loan remittance types.)
Credit Score
All government mortgage loans are subject to a minimum representative credit score of 620. Manually underwritten government mortgage loans with nontraditional credit are exempt from this policy.
Delivery of Government Mortgage Loans
For government mortgage loans, the lender must report all applicable data elements at delivery, including but not limited to, the Section of the Act and certain government loan-specific special feature codes. Refer to the Fannie Mae Implementation Guide for Loan Delivery Data on Fannie Mae's website for additional information.
