The Quick Read: You layer three things: one assistance option, whatever incentives the builder offers, and a government-backed first mortgage. Each layer may pay only the costs the rules let it pay. Assistance does not stack with another assistance program, so the real stack is assistance plus builder money. It applies to an owner-occupied primary residence only.
Key Takeaways
- Three layers sit in every stack: the first mortgage, one assistance option, and the builder’s incentives.
- The assistance and the builder’s money are tested separately. A builder credit can help with closing costs, but it cannot fund your minimum investment on an FHA loan.
- You do not need to be a first-time buyer. Repeat and move-up buyers qualify.
- A second assistance program on top of the first is off the table, and so is a rental or second home.
- New construction adds its own paperwork, so a stack can pass the assistance rules and still stall on the build.
What Does “Stacking” Actually Mean on a New Build?
Stacking means layering funding sources so each pays a different part of your cash to close. You are not combining three assistance programs. You are fitting three pieces together, and each piece has its own rules.
The first piece is the first mortgage: FHA, USDA or HUD-184. FHA asks for a minimum required investment of 3.5% of the lesser of price or appraised value, which gives 96.5% first-lien leverage. The upfront mortgage insurance premium is a percentage of the base loan, and it can be financed into the loan. Annual mortgage insurance follows by tier.
The second piece is the assistance. Through wholesale lenders, Lendmire arranges four shapes of down payment assistance programs beside those first liens. All are subject to program guidelines and full underwriting. One of the four fits a given file, never two.
The third piece is the builder. Builders offer closing-cost credits, buydowns and upgrade packages. Those get tested on their own track, and that track is where most stacks run into trouble.
Here is a wry truth about new construction: the sales office will quote you a number before anyone has checked which dollars are allowed to pay for what.
How Is the Stack Underwritten, Step by Step?
The lender tests the first lien, the assistance and the builder money one at a time. Then it checks that they add up without overlapping. Here is the order the files usually follow.
1. Pick the first lien. FHA 203(b) is the most common base on a new build. The grant option pairs only with FHA first liens. The forgivable and repayable seconds also pair with USDA and HUD-184.
2. Pick the assistance shape. Credit score, income, unit count and your situation decide this. The table below walks through the four.
3. Disclose everything at application. The second lien is its own loan with its own disclosures. The builder’s credits go on the sales contract, and they show up again on the Loan Estimate and Closing Disclosure.
4. Run the automated underwriting finding. The assistance options follow that finding. A repayable second adds a monthly payment, and that payment counts in your debt ratios. A grant or forgivable second adds none.
5. Size the assistance on price or value. The grant is a percentage of price. The forgivable and repayable seconds use the lesser of price or appraised value. A low appraisal on a new build shrinks the assistance with it.
6. Keep the money streams apart. Your funds, the assistance and the builder credits each get their own line. A cost paid by one source cannot be paid again by another.
7. Complete the new-construction file. That means the builder’s certification of plans and site, the warranty of completion, and the permit and certificate of occupancy where applicable.
8. Record the liens in order. The first mortgage goes first. The second sits behind it.
A small honest point: steps 1 through 6 are the easy part. Step 7 is where schedules slip.
What Are the Four Shapes of Assistance?
There are four shapes. Which fits depends mostly on your credit score, your situation and what you need covered. Every figure here is a percentage of price or value, not a dollar promise.
| Shape | Size | Repay? | Credit floor |
|---|---|---|---|
| Grant | 2% or 3.5% of price | Nothing to repay | 620 |
| Forgivable second | 3.5% of lesser of price or value | Forgiven after 36 or 60 on-time payments | 640 |
| Repayable second | 3.5% or 5% of lesser of price or value | Yes, 30-year amortization, balloon in year 10 | 660 |
| Refinance-cost second | 1% to 3.5% of balance | Yes, same terms as repayable | 660 |
The grant goes toward the FHA minimum required investment. It releases at closing, with no lien, no payment and no interest. Qualification takes household income at or below 140% of area median income, or a qualifying category. Those categories include first responders, educators, medical workers, civil servants, military personnel, first-time buyers and buyers in an underserved census tract. A homebuyer education course is required, and the grant is not offered in Washington. It also works only with an FHA first lien at 96.5% leverage, on one to four units. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
The forgivable second carries no interest and no monthly payment. It is forgiven after the first 36 or 60 on-time first-lien payments, with no 90-day delinquency. It covers one to two units and has no income limit beyond USDA’s own on a USDA first lien. Manual underwriting is allowed.
The repayable second is a real loan. It carries interest, a monthly payment, a 30-year amortization and a balloon due in year 10. At 5%, it covers the 3.5% minimum investment plus 1.5% toward closing costs and prepaids. High-balance first liens are allowed, but manual underwriting is not.
The refinance-cost second applies to an FHA 203(b) refinance, not a purchase. It is here only so you can see the full set. It matters if you refinance later, and a refinance is a separate decision.
A lower-scoring co-borrower’s score can be blended in on the second-lien options. That requires the primary wage earner to earn at least 60% of household income and hold the higher score. The minimums become 660 for the forgivable and 670 for the repayable, and an automated approval is required.
On eligibility, no option requires you to be a first-time buyer. Repeat and move-up buyers qualify, and the first-time definition is only one of the grant’s qualifying categories.
Builder Money vs. Assistance Money
Builder credits and assistance are different buckets, and the rules treat them differently. Builders count as interested parties, and HUD’s FHA guidance caps what interested parties may contribute at 6% of the sales price. It lists closing costs and prepaid items as the costs they can cover. It also says that interested-party contributions may not be used for your minimum investment.
Anything above the cap, or above your actual costs, is treated as an inducement to purchase. That lowers the price used to calculate the loan amount, dollar for dollar. Credits from the lender itself are handled differently, provided the lender is not the builder.
| Cost | Assistance can help | Builder credit can help |
|---|---|---|
| Minimum investment | Yes, per the option | No, on FHA |
| Closing costs | Yes, at 5% repayable | Yes, up to the cap |
| Prepaid items | Yes, at 5% repayable | Yes, up to the cap |
| Price reduction | Not applicable | Counts as a lower price |
Some say “just have the builder gift me the down payment.” On FHA, that fails. The cleaner version is a builder credit toward closing costs and assistance toward the minimum investment, with each dollar counted once.
The rules also reach the assistance itself. HUD does not approve down payment assistance programs. The lenders using them must make sure the funds comply with FHA requirements. That is why a wholesale lender reviews each file and each source rather than trusting a label.
Ask whether a builder’s closing credit is tied to its preferred lender. Some are, and that matters because the assistance runs through a different lender. Get the answer in writing before you sign the contract.
Where Does the General Rule Break?
The general rule is that one assistance option plus builder credits works on a primary home. These edge cases are where it bends.
USDA and the new-build paperwork. USDA offers no minimum down payment, but a new home without plan certification, inspection and warranty paperwork is limited to 90% loan-to-value, per the USDA loan origination FAQ. That caps the loan unless the builder produces the documents. A forgivable or repayable second then sits behind the USDA loan, and USDA’s income limits still apply.
A later USDA refinance. It must be subordinated or paid in full. A repayable second with a balloon in year 10 makes that a real planning point.
HUD-184. Native American borrowers can use the Section 184 loan on a new build. The HUD Section 184 policy handbook says the program itself does not provide down payment assistance or grants. The assistance comes from the forgivable or repayable second arranged beside the first lien.
The one-time-close loan. A single-close construction-to-permanent loan is not allowed with the grant. Assistance on these files is built around buying a home that is complete or close to it. A loan that pays a builder in draws while you wait is a different product. If your build needs draws, ask early whether assistance can attach at all.
The appraisal gap. A new build can appraise below the contract price. The forgivable and repayable seconds are sized on the lesser of price or value, so a gap shrinks the assistance. You would cover the difference or renegotiate.
Timing. A long build can outlast reservation and commitment windows on the assistance. Ask the builder for a realistic completion schedule before you commit, and ask the lender how long the assistance commitment lasts.
Rental and second homes. Assistance is for owner-occupied primary residences only, so a rental or vacation home is outside every option here.
Two programs at once. No option combines with another assistance program. A mortgage credit certificate is not permitted with the second-lien options either.
Minor repairs. On the second-lien options, minor non-structural repairs of up to $5,000 can be handled through an escrow holdback of 150% of the estimate. That helps when a finished new home has a small punch-list item.
Three Buyer Pictures
These are percentages and plain words, not quotes. Every file is underwritten individually.
A move-up buyer, finished inventory home. She teaches school and has sold a prior home, so she is not a first-time buyer. Her category qualifies her for the grant at 3.5% of price on an FHA first lien. The builder offers a credit toward closing costs, and she keeps it under the 6% cap. The grant covers the minimum investment and the builder credit covers closing costs. Nothing overlaps.
A renter buying a to-be-built home. His score sits at 650, which clears the forgivable second but not the repayable one. The build runs long, so the reservation and commitment windows are the real risk. He asks the lender for the assistance commitment terms before signing. Then he ties the contract’s completion date to them. With the forgivable second, he owes no payment and no interest as long as he makes his first-lien payments on time, because the lien is forgiven after the 36 or 60 payments.
A buyer whose stack fails. He wants the grant, plus his county’s program, plus a builder gift to cover the minimum investment. Three problems show up. Assistance does not stack with assistance, the builder gift cannot fund the minimum investment, and the grant does not pair with the county program. He picks one assistance option and routes the builder money to closing costs instead.
What Does the Buyer’s Decision Look Like in Practice?
Make the decisions in this order. First, confirm the home will be your primary residence. Second, choose the first lien that fits the property and your county. Third, match one assistance shape to your credit score and situation. Fourth, ask the builder what its incentives require and whether they fit under the cap.
Before you sign a contract, ask the builder and the lender these questions:
- Is the builder’s credit tied to a preferred lender?
- How are credits and buydowns counted against the 6% cap?
- When will the plan certification, inspection and warranty paperwork be ready?
- How long does the assistance commitment last compared with the build schedule?
- What happens to the assistance if the appraisal comes in low?
- What does the second lien cost you if you sell or refinance?
For the grant, the course is a homebuyer education class from an HUD-approved provider. You pay up front, and the cost is credited back at closing.
Key Terms Defined
Minimum required investment: The share of the purchase you must pay yourself under FHA rules, 3.5% of the lesser of price or appraised value. The grant option can fund it.
Interested party: Anyone with a stake in the sale, including the builder, the developer and the real estate agent. Their contributions are capped and limited to certain costs.
Soft second: A second lien with no interest and no payment that is forgiven over time if you keep paying your first mortgage. Lendmire’s forgivable option works this way.
Balloon: A lump sum due at the end of a loan term. The repayable second has one in year 10.
Combined loan-to-value: The first lien plus any second lien, divided by price or value. The refinance-cost second runs to 104%.
Next Step
If you are buying a primary home and want to see whether a down payment assistance option fits your file, Lendmire can help you compare the grant, forgivable and repayable structures alongside an FHA, USDA or HUD-184 first mortgage. Lendmire is a mortgage broker and arranges these through wholesale lenders. Programs change, and approval is not a commitment to lend.
Frequently Asked Questions
Can I use down payment assistance and a builder credit together?
Yes, with limits. The builder credit can go toward closing costs up to the interested-party cap, but not toward your FHA minimum investment. The assistance can fund the minimum investment. Each cost is paid once, and the lender reviews the totals.
Do I have to be a first-time buyer?
No. Repeat and move-up buyers qualify for the assistance options. The first-time buyer definition is just one of the categories that can qualify you for the grant.
Can I stack two assistance programs on one new home?
No. No option combines with another assistance program, and the second-lien options cannot be paired with a mortgage credit certificate. Choose one assistance option and pair it with builder credits.
Does the second lien cost me anything after closing?
It depends on the shape. The grant has nothing to repay, and the forgivable second has no payment and no interest. The repayable second does have interest, a monthly payment and a balloon in year 10, so it is a real loan.
Does assistance work on a home I haven’t built yet?
Sometimes. It is designed around buying a home that is complete or close to completion. A one-time-close construction loan is not allowed with the grant, so ask your lender whether your build timeline fits before you sign.
