Down payment grants vs assistance loans: which to choose
Down payment help comes in two broad forms. A grant does not have to be paid back. An assistance loan sits behind your mortgage as a second lien, and whether you ever repay it depends on terms that are easy to skim past. Knowing which one you are being offered changes how you should weigh it.

When a program offers "down payment assistance," the first thing to find out is whether you are being given money or lent it. The FDIC's guide to state housing finance agency programs describes the range: forgivable grants, zero-interest deferred second mortgages often called "soft seconds," and full-interest, fully amortizing second loans. The dollar amount is the headline, but the structure decides what it really costs you.
The four structures
| Type | Monthly payment | Repaid when |
|---|---|---|
| Grant | None | Never, if it is a true grant |
| Forgivable loan | Usually none | Only if you break a condition, such as selling early |
| Deferred loan | None | When you sell, refinance or pay off the first mortgage |
| Repayable second loan | Yes | Over its term, like any loan |
Grants. The FDIC guide says plainly that grant funds do not have to be repaid. For a conventional loan, Fannie Mae requires the award letter or agreement to include language that repayment is not expected and to explain how the funds will be provided. Grants must come from an eligible source, such as a government agency, nonprofit or lender, and not from the seller or another interested party.
Forgivable loans. These are recorded as a second lien but are reduced or cancelled over time if you meet the program's conditions, typically living in the home as your main residence for a set number of years. Sell, rent it out or refinance too soon and some or all of the balance may be due.
Deferred loans. No payments and often no interest, but the whole amount comes due later. The FDIC guide warns that soft-second terms can be difficult to understand, borrowers sometimes forget the loan exists until repayment is due, and some carry restrictions on transfer or sale.
Repayable second loans. These work like any small mortgage: a rate, a term and a monthly payment that counts in your debt-to-income ratio.
What each one costs if plans change
The difference between these structures shows up when you leave early. Picture $10,000 of help and a move in year four:
- A grant costs nothing.
- A forgivable loan that forgives 20% a year over five years would leave $2,000 due, if the program forgives on that schedule.
- A deferred loan would leave the full $10,000 due from your sale proceeds.
- A repayable loan would have cost you four years of payments, and the remaining balance would be paid at sale.
These terms are simplified for illustration. Real programs set their own forgiveness schedules and triggers, which is why you need the actual documents.
Rules that matter more than the amount
The FDIC guide notes that most state housing finance agency assistance must be used with that agency's own first mortgage. That pairing is where hidden cost can sit. Compare the first mortgage's rate and fees with what you could get elsewhere. A large grant attached to a noticeably higher rate can cost more over time than a smaller grant paired with a cheaper loan.
Other common conditions include:
- Income and price limits. The FDIC guide says these are often stricter for the assistance than for the agency's first loan, so qualifying for one does not guarantee the other.
- First-time buyer status, often defined as not owning a home in the past three years.
- Homebuyer education before closing.
- Occupancy. The home must be your main residence.
Fannie Mae also adds a funding rule: down payment assistance may not be funded in any way through the first mortgage, for example through premium pricing that raises your rate.
How assistance fits your loan
Grants do not add a lien, so they do not change your combined loan-to-value. Assistance loans do. For Fannie Mae loans, eligible assistance loans from housing agencies and similar providers are handled under its Community Seconds rules, which allow combined loan-to-value ratios above the usual limits when the second loan comes from an approved type of provider.
On how much of your own money you need: for a one-unit principal residence, Fannie Mae requires no minimum contribution from your own funds when a grant is used, even when the loan-to-value is over 80%. For two- to four-unit homes above 80%, you must put in 5% of your own funds before grant money can be used.
Questions to ask
Before you build a purchase around assistance, get written answers to these:
- Is this a grant or a loan? If a loan, is it forgivable, deferred or repayable?
- What exactly triggers repayment, and is the amount reduced over time?
- Does refinancing count as a trigger, and will the program agree to stay in second position if you refinance?
- Must I use your first mortgage, and what are its rate and fees?
- How long does approval take, and are funds limited? The FDIC notes grant programs may run out faster.
- Is any part of the help taxable? Ask the program and a tax professional.
A HUD-approved housing counseling agency can help you compare programs, and the CFPB suggests starting there to find local options. Your state housing finance agency, listed by NCSHA, publishes its own program terms.
The bottom line
Grants are money you keep; assistance loans are obligations with conditions. Read the terms for what triggers repayment, compare the first mortgage that comes with the help, and choose the structure that fits how long you realistically plan to stay. When in doubt, a housing counselor can lay two offers side by side with you.
Comparing assistance offers
- Get the award letter or loan terms in writing before you rely on the money.
- Find out whether it is a grant, forgivable loan, deferred loan or repayable loan.
- Note any occupancy period and what triggers repayment.
- Ask whether the help must be paired with a specific first mortgage and compare that mortgage's rate.
- Check income limits, price limits and homebuyer education requirements.
- Ask what happens if you refinance during the program period.
Questions buyers ask
Do down payment grants have to be repaid?
A true grant does not. Fannie Mae requires the grant document to say repayment is not expected. Some programs call forgivable loans grants, though, so read the terms for any condition that could trigger repayment.
What is the difference between a forgivable loan and a deferred loan?
A forgivable loan is reduced or cancelled if you meet its conditions, often living in the home for a set number of years. A deferred loan charges little or no interest and needs no monthly payment, but the full amount is due when you sell, refinance or pay off the first mortgage.
Can a grant cover my whole down payment?
On a Fannie Mae one-unit principal residence, yes. Fannie Mae requires no minimum contribution from your own funds for one-unit homes, even above 80% loan-to-value. Two- to four-unit homes over 80% need 5% from your own funds first.
Why would anyone choose a loan over a grant?
Often there is no choice: the FDIC notes grant programs may run out of funds faster than loan programs, which are replenished by repayments. Loans may also offer larger amounts. If both are available, compare the total cost under realistic plans for how long you will stay.
