The Quick Read: In practice, you pick one assistance structure and build around it. You do not add several programs together. Each option is sized as a percentage of price or value, so a higher price produces more assistance. The real ceiling is the first mortgage: FHA, USDA or HUD-184 limits, your debt ratios, and the program’s own eligibility gates decide what works.
Key Takeaways
- Assistance is one layer, not a pile. Across the wholesale programs Lendmire places files with, no assistance option combines with another assistance program.
- Percentage-based help scales with price. The first-lien loan limit and your budget still cap the result.
- Only the grant has nothing to repay. The forgivable and repayable options are second loans, and you should treat them as debt.
- No option requires a first-time buyer. Repeat and move-up buyers qualify.
- Everything here is for an owner-occupied primary residence. A second home or rental does not qualify.
What Does “Stacking” Actually Mean?
Stacking means layering several sources of money toward one purchase. Some layers combine. Others do not. Sorting them is most of the work.
Here are the layers a buyer might hold:
- The first mortgage: FHA, USDA or HUD-184.
- One assistance option: grant, forgivable second, or repayable second.
- Your own savings: cash you bring.
- Gift funds: money from an allowed donor, such as family.
- Seller or builder credits: money toward costs, negotiated in the contract.
The one thing that does not stack is assistance on assistance. The programs Lendmire arranges do not allow a second assistance program on the same file. A mortgage credit certificate is also off the table with the second-lien options.
The advertised maximums you see online don’t add up for that reason. A buyer in an expensive market who reads three program pages and adds the percentages together is doing arithmetic the programs won’t honor.
The Four Shapes of Assistance
Lendmire is a mortgage broker licensed for consumer lending in 16 states. It arranges FHA, USDA and HUD-184 first mortgages with these assistance options through wholesale lenders, subject to program guidelines and full underwriting. Here is how the four shapes compare.
| Feature | Grant | Forgivable second | Repayable second | Refinance-cost second |
|---|---|---|---|---|
| Size | 2% or 3.5% of price | 3.5% of price or value | 3.5% or 5% | 1% to 3.5% of balance |
| Repay? | Nothing to repay | Forgiven over time | Yes, with payments | Yes, same terms |
| Credit floor | 620 | 640 | 660 | 660 |
| First lien | FHA only | FHA, USDA, HUD-184 | FHA, USDA, HUD-184 | FHA refinance |
“Lesser of price or value” means the lender uses whichever number is lower. That matters in a bidding war. If you pay more than the appraisal, the percentage is calculated on the appraisal.
The sections below walk through each shape.
How the Grant Works
The grant is often a strong option with nothing to repay. It comes as 2% or 3.5% of the purchase price, released at closing. There is no lien, no payment and no interest.
It pairs with an FHA first mortgage at 96.5% loan-to-value. That is the loan size left after the 3.5% minimum investment. Loan-to-value, or LTV, is the loan amount divided by the property value. The credit floor is 620, and the property can be one to four units. It is not offered in Washington.
The grant carries an income test, but not for everyone. You qualify if household income is at or below 140% of area median income. You also qualify if you fall into a listed category, regardless of income:
- First responders, current, former or entering service
- Educators
- Medical personnel
- Civil servants at the federal, state or local level
- Military personnel, current, retired or volunteer
- First-time buyers
- Buyers in an underserved census tract
A first-time buyer here means no ownership interest in a residential property in the prior three years. That is only one of the doors. A repeat buyer who teaches or nurses still gets in.
You also complete an HUD-approved homebuyer education course. You pay up front, and the cost is credited back at closing. The grant does not combine with FHA High Balance, FHA $100 Down, or any other assistance program.
That last point matters in expensive markets. The grant does not work with a high-balance first lien, so it fits best where the county limit already covers your loan.
How the Forgivable Second Works
The forgivable second is a loan that disappears if you stay. It equals 3.5% of the lesser of price or appraised value. It carries no interest and no monthly payment.
The lien is forgiven after your first 36 or 60 on-time first-lien payments. You pick the three-year or five-year version. A 90-day-or-greater delinquency breaks the clock.
The credit floor is 640, or 660 on a blended score. It pairs with FHA 203(b), FHA Limited 203(k), HUD-184 and USDA first liens, on one to two units. There is no income limit beyond USDA’s own on a USDA loan. Manual underwriting is allowed, and no homebuyer counseling is required.
The catch: it is still a lien until forgiven. Sell or refinance inside the window and you should expect to settle what has not yet been forgiven. Plan to stay.
How the Repayable Second Works
The repayable second is a real loan. You borrow 3.5% or 5% of the lesser of price or appraised value. It is interest-bearing and has a monthly payment. It amortizes on a 30-year schedule with a balloon due in year 10.
A balloon means the remaining balance comes due all at once. Most buyers handle that by selling or refinancing before then. Go in with that plan.
At 5%, the money covers the 3.5% minimum investment plus 1.5% toward closing costs and prepaid items. Prepaids are the taxes and insurance you pay in advance at closing. At 3.5%, it covers the down payment only.
The credit floor is 660, or 670 blended. High-balance first liens are allowed here, and manual underwriting is not. The second carries no lender fees. It has prepaid interest, recording, settlement and registration charges only. It also has its own Loan Estimate-style disclosure and a balloon disclosure, because it is a separate consumer loan.
For the plain-language overview, see Lendmire’s page on down payment assistance programs.
The Refinance-Cost Second
Not every file is a purchase. A fourth shape covers 1% to 3.5% of the lesser of your current first-lien balance or appraised value. It goes toward the closing costs of an FHA 203(b) refinance.
Combined leverage can reach 104%. It cannot be used on a streamline refinance, and it cannot refinance an existing assistance loan. Repayment terms match the repayable second.
How the First Lien and the Assistance Are Underwritten, Step by Step
The lender tests the first mortgage and the assistance as one file. Here is the order.
1. Pick the first lien. Each one sets its own gates. FHA sets county loan limits and a 3.5% minimum investment. USDA needs no down payment but limits location and income. HUD-184 serves tribal members.
2. Pick the assistance shape. A grant is cash with no lien. The seconds are liens and count as secondary financing.
3. Check eligibility. Credit floor, unit count, income test (for the grant), and education course (for the grant).
4. Run the debt ratios. The lender adds the required payment on the second, if there is one, to your housing costs and other debts. Underwriters call this the debt-to-income, or DTI, ratio. FHA manual underwriting uses 31% for housing and 43% for total debt. Automated findings often allow more, and the assistance options follow the automated finding.
5. Confirm lien order. The government-backed loan must sit in first position. USDA’s handbook on closing the loan requires title evidence showing other liens as subordinate to the guaranteed loan, and it allows a guaranteed loan up to 100% of appraised value plus the upfront guarantee fee.
6. Assemble the file. Application, the assistance note and subordinate lien documents, the education certificate for the grant, and the automated underwriting approval.
A forgivable or deferred second with no required payment generally does not enter your monthly debt ratio. A repayable second does. That is why the repayable option can strain a tight budget even though it adds cash at closing.
Blended scores matter on the second-lien options. If a lower-scoring co-borrower is on the loan, their score is averaged in only when the primary wage earner earns at least 60% of household income and holds the higher score. Automated approval is required.
Why a High-Cost Market Changes the Math
High prices change two things: the size of the minimum investment and the limit on the first loan.
The FHA minimum investment is 3.5% of the lesser of price or value. On a bigger loan, that is a bigger check. Assistance sized as a percentage grows with price, which is why these options help in expensive metros.
But the first lien has a ceiling. HUD’s FHA limits for one-unit homes run from $541,287 to $1,249,125 depending on county. Most counties sit near the lower figure. Only designated high-cost counties approach the top. Check your county before you shop.
Assistance cannot bridge a loan that exceeds the limit. If your price is above what the county limit supports, the gap comes from your own cash.
USDA is a different story. It requires an eligible rural area and income within 115% of area median. Dense, expensive metros rarely qualify, though some suburban addresses do. Check the address on USDA’s tools instead of assuming.
Two more squeezes show up in expensive places:
- Two-earner income. The grant’s income test is 140% of area median unless a category applies, so a dual-income household can exceed it. A listed category, such as teaching or nursing, often fixes that.
- Property caps on other programs. Many public programs cap purchase price to keep funds on modest homes, so they may not reach high-cost prices at all.
For a deeper look at how price limits vary, see Lendmire’s piece How High Down Payment Assistance Price Caps Go by Market.
A Buyer Scenario in Percentages
Picture a renter moving up into a pricey county. The price sits well above the national floor but under that county’s FHA limit. She is a nurse with a 660 score.
Her best fit is probably the grant, if her credit holds at 620 or higher. As a medical worker, she clears the income question whichever way her household earns. She gets 2% or 3.5% of price toward the minimum investment, with nothing to repay. She completes the education course, and the first lien is FHA at 96.5% loan-to-value.
Now change one fact. Her price pushes her into a high-balance loan. The grant drops out, since it does not pair with high balance. The repayable second at 3.5% or 5% stays available, because high-balance first liens are allowed there. She trades a no-repayment structure for a loan with a payment and a year-10 balloon.
Same buyer, same county. The first-lien size decided the assistance shape. That is the pattern: work backward from the loan, not forward from the program you like.
Where the General Rule Breaks
The rule of thumb is one assistance option per file, sized by percentage. These edge cases bend it.
- Gift funds are a different layer. A gift from an allowed donor can count toward your minimum investment. FHA gift rules, as summarized in this industry explainer on FHA gifts, permit family, employers, charities and certain public entities. Seller gifts are not allowed.
- Government and nonprofit sources differ on FHA. A government source must document its authority. A nonprofit second needs advance FHA approval.
- Grant versus loan labels. The same dollars are a gift if no repayment is expected, and secondary financing if a lien secures them. Labels can blur, so ask which one you are getting.
- Seller credits. These cover costs, not the minimum investment. A large credit can also trigger appraisal trouble if the home comes in low.
- USDA combined liens. USDA treats assistance seconds specially, and your lender confirms the current rule. Some new-construction purchases that can’t meet documentation requirements are capped at 90% loan-to-value, according to USDA’s loan origination FAQ.
- HUD-184. The program guarantees the loan. It does not provide assistance itself, according to HUD’s Section 184 handbook. Help comes from a tribe, a tribally designated housing entity or another program, and the junior-lien details are still being clarified.
- Escrow holdbacks. On the second-lien options, minor non-structural repairs up to $5,000 can be escrowed at 150% of the estimate, with completion timing set by the lender and the file.
- Repairs and renovation. A limited 203(k) first lien carries renovation up to $75,000.
Manufactured housing appears in the program matrix, but most buyers should start with the standard property types: single-family, condo, or PUD.
What the Stack Costs You Later
Cash saved now is not cash saved forever. Here is the tradeoff, option by option.
| Option | Cash help now | Cost later |
|---|---|---|
| Grant | Covers part of minimum investment | None, beyond mortgage insurance |
| Forgivable second | 3.5% toward down payment | Repay if you leave early |
| Repayable second | 3.5% or 5% | Monthly payment plus year-10 balloon |
The first lien has its own costs regardless. FHA charges an upfront mortgage insurance premium based on the base loan amount, which can be financed. There is also an annual premium. At 90% LTV or below, it lasts 11 years. Above 90%, it lasts the life of the loan.
A second lien also comes out of your proceeds when you sell. And early on, it limits how much you can borrow in a refinance. Think about the stack as the total debt against the house, not just the cash at closing.
Key Terms Defined
Assistance: Money toward your down payment or closing costs, structured as a grant or a second loan.
Second lien: A loan secured by your home that sits behind the first mortgage. If you sell, it is paid after the first.
Forgivable: A loan balance that is erased if you meet a condition, here a set number of on-time payments on the first mortgage.
Balloon: A single large payment due at the end of a loan term, covering whatever balance remains.
Minimum required investment: The part of the price you must put in yourself on an FHA loan, 3.5% of the lesser of price or appraised value.
Combined loan-to-value: All loans on the home added together, divided by the property’s value.
How to Build Your Stack: A Practical Path
1. Start with the price and county. Find the FHA limit for your county. That tells you whether you are in standard or high-balance territory.
2. Check your credit. Your lowest representative score decides which options are open: 620, 640 or 660.
3. Decide how long you will stay. Five years or more makes the forgivable option attractive. A shorter horizon favors the grant or a plan for the balloon.
4. Check the grant’s gates. Does your income, job or situation meet one of the qualifying paths?
5. Test your budget. If you consider a repayable second, count its payment in your monthly budget.
6. Add your own layers. Savings, allowed gift funds and negotiated seller credits fill what assistance does not.
7. Talk to a housing counselor. HUD-approved counselors give independent advice, often at little or no cost. The CFPB’s housing counselor finder lists them.
The Urban Institute reports that more than 1,600 programs offer assistance nationwide. Many buyers never learn that. Checking is worth the hour.
Frequently Asked Questions
Can I use two assistance programs on the same home?
No. None of the options combines with another assistance program. You can pair one option with your own savings, allowed gift funds and negotiated seller credits, subject to program guidelines. A mortgage credit certificate also cannot go with the second-lien options.
Do I have to be a first-time buyer?
No. Repeat and move-up buyers qualify across all four shapes. The three-year no-ownership test appears only as one of several qualifying paths for the grant. A teacher or nurse who already owns a home can still use it.
Does assistance work on a second home or rental?
No. Assistance is for an owner-occupied primary residence only.
Is the second lien really a loan?
Yes. The forgivable second is a loan that gets forgiven after 36 or 60 on-time first-lien payments. The repayable second carries interest, a monthly payment and a balloon in year 10. Both are liens against your home, and both are underwritten individually through wholesale lenders.
What happens if I sell early?
With a forgivable second, you generally settle the unforgiven balance from the sale. With a repayable second, the balance is paid from proceeds. The grant has no lien, so there is nothing to settle.
