What Community Seconds Loans Are
A Community Seconds loan is a second mortgage that comes from an affordable housing program. These programs help homebuyers by providing additional financing for down payments, closing costs, or other homeownership expenses.
Think of it this way: you get your main mortgage from a bank or credit union, and you get a smaller second loan from a local housing authority, nonprofit organization, or government agency. The second loan helps bridge the gap between what you can afford and what you need to buy the home.
Say you're buying a $300,000 home and can put down $15,000. You need a $285,000 first mortgage, but you also need $8,000 for closing costs. A Community Seconds program might provide that $8,000 as a second mortgage with favorable terms — maybe a low interest rate, deferred payments, or even forgiveness after you live in the home for several years.
How Fannie Mae Treats These Loans
Fannie Mae takes a specific approach to Community Seconds loans. They will not buy the second mortgage itself, but they will purchase your first mortgage as long as the Community Seconds program meets their requirements.
This matters because it means your primary lender can still sell your first mortgage to Fannie Mae, which helps keep mortgage rates competitive. Without this flexibility, lenders might not offer loans to borrowers using Community Seconds financing.
Your lender must review the Community Seconds program before approving your loan. They cannot just accept any second mortgage program — it has to comply with Fannie Mae's rules.
What Your Lender Must Verify
Your lender has specific responsibilities when you want to use Community Seconds financing. They must review all the program documents to make sure everything complies with Fannie Mae guidelines.
The lender will examine the promissory note and security instrument for the second mortgage. They need to confirm that the second mortgage is clearly subordinate to your first mortgage. This means if you default, the first mortgage lender gets paid first from any foreclosure proceeds.
The title insurance must show the Community Seconds loan in a subordinate position. This creates a clear legal hierarchy — your first mortgage comes first, the Community Seconds loan comes second.
Your lender must also confirm that the Community Seconds program allows the first mortgage holder to foreclose and get clear title to the property. The second mortgage cannot create restrictions that would prevent a normal foreclosure process.
Required Documentation
Your lender will need complete documentation of the Community Seconds program. This includes the promissory note that spells out your repayment terms, the security instrument that secures the loan against your property, and a full program description.
The lender must review any deed restrictions or option agreements that come with the Community Seconds loan. Some affordable housing programs include resale restrictions that limit how much profit you can make when you sell the home.
Fannie Mae provides a Community Seconds Checklist that lenders can use to evaluate these programs. This checklist helps ensure they review all the key requirements systematically.
The title insurance policy must clearly show the priority of both mortgages. The first mortgage must be in first position, and the Community Seconds loan must be subordinate.
Why These Rules Exist
Fannie Mae created these requirements to protect both borrowers and the mortgage market. The subordination requirement ensures that first mortgage lenders can recover their investment if borrowers default, which keeps mortgage rates lower for everyone.
The program review requirement prevents problems down the road. If a Community Seconds program has terms that conflict with the first mortgage, it could create legal complications during foreclosure or resale.
The documentation requirements create transparency. Everyone involved — the borrower, first mortgage lender, and Community Seconds provider — knows exactly what their rights and obligations are.
Common Complications
Some Community Seconds programs include resale restrictions that can complicate your loan approval. For example, a program might require you to share appreciation with the housing agency when you sell, or limit the sale price to keep the home affordable for the next buyer.
These restrictions do not automatically disqualify you, but they trigger additional Fannie Mae requirements under guidelines [[B5-5.2]] and [[B5-5.3]]. Your lender must evaluate whether these restrictions comply with Fannie Mae's policies on shared equity transactions.
Programs that give the Community Seconds provider an option to purchase your home at below-market rates can create problems. If this option interferes with normal foreclosure procedures, Fannie Mae may not purchase your first mortgage.
Some Community Seconds loans have payment terms that change based on your income or the home's value. While these features can help affordability, they may require additional documentation and review to ensure they do not conflict with your first mortgage terms.
Local ordinances sometimes impose restrictions similar to formal Community Seconds programs. Your lender must review these as well to ensure compliance with all Fannie Mae policies.

Review of Community Seconds Programs
The lender is responsible for reviewing Community Seconds programs to ensure the programs comply with this Guide. The Community Seconds Checklist includes a checklist that lenders may use to evaluate key considerations in determining whether to grant approval of a Community Seconds program.
The following table provides lender requirements for reviewing a Community Seconds program.
✓
The lender must...
Review all documents applicable to the program, including the legal documents (such as the promissory note and the security instrument), the program description, and any other pertinent documents to confirm compliance with Section B5-5.1, Community Seconds.
Determine the mortgage for the Community Seconds loan is clearly subordinate to the first mortgage. The title insurance in effect must ensure priority of the first mortgage being delivered to Fannie Mae by showing the Community Seconds loan in a subordinate position.
Confirm the program allows the holder of the first mortgage to foreclose and acquire title to the property free and clear of all interests of the Community Seconds provider.
If applicable, evaluate any recorded deed restrictions or option agreements, or local ordinances that impose similar restrictions, to confirm compliance with other Fannie Mae policies, such as those applicable to resale restrictions (see Section B5-5.2, Loans with Resale Restrictions and Section B5-5.3, Shared Equity Transactions).
