The Quick Read: “Minimum contribution” is really three separate questions: what the loan agency requires, where that money may come from, and whether the building itself passes review. FHA requires 3.5% of the property’s value, and qualifying assistance can fill it. USDA requires no down payment at all. Condo approval and the FHA test for 3-4 unit buildings can block a deal no matter how the minimum is funded.
Most buyers ask one question: “How much of my own money do I need?” The honest answer has layers. This article walks through each layer in the order a lender checks them.
Key Terms Defined
Minimum required investment (MRI): the cash or cash-equivalent the borrower must put into the purchase. On FHA, it is at least 3.5% of the property’s adjusted value, per the HUD Handbook 4000.1 Glossary.
First lien: the main mortgage. It gets paid first if the home is sold or foreclosed.
Second lien: a smaller loan recorded behind the first mortgage. It can be repayable or forgivable, but it is still a lien.
Single-Unit Approval (SUA): an FHA path for one unit in a condo building that has not been approved as a whole project.
Self-sufficiency test: an FHA check on 3- and 4-unit homes. The property’s projected rent, discounted for vacancy and costs, must cover the housing payment.
Association reserve contribution: the money a condo association sets aside for repairs. It is not your contribution. The two get confused online, so keep them apart.
Three Questions Hiding in One
Here is the sequence a lender follows.
1. Does the property pass? A condo needs project approval. A 3-4 unit building needs to pass the rent test.
2. What does the agency require? FHA wants 3.5%. HUD-184 wants a smaller percentage. USDA wants none.
3. Where can the money come from? This is where down payment assistance either fits or fails.
Test the property first. A buyer can be fully qualified for assistance and still lose the purchase because the building fails review. Check project status before you fall in love with a unit.
One note on scope: assistance is for an owner-occupied primary residence only. It does not apply to second homes or rentals. Buying a duplex to live in one side counts as a primary residence. Buying it to rent both sides does not.
What Each Agency Requires
FHA. The minimum investment is 3.5% of the lesser of price or appraised value. The HUD glossary does not set a different percentage for 2-4 unit homes, so do not assume one. Beyond the minimum, FHA charges an upfront mortgage insurance premium that is calculated on the base loan and can be financed into the loan. Annual mortgage insurance follows by tier. FHA’s 2026 one-unit loan limits run from $541,287 to $1,249,125 depending on the county.
USDA. The guaranteed program has no required down payment. Per USDA’s guaranteed loan handbook, the maximum loan is 100% of appraised value plus the upfront guarantee fee. USDA lists condos among eligible attached property types, but the home must be a permanent residence and cannot be income-producing. So USDA fits single-family homes and condo units. It is not a route to a rental duplex or triplex.
HUD-184. This program serves eligible Native American borrowers. It is a loan guarantee. HUD says it does not provide down payment assistance itself, so help has to come from a tribe, a state, a local program, or a gift. Its minimum investment is 2.25% of the lesser of appraised value or acquisition cost on properties over $50,000, per the 24 CFR 1005.443 source rules. Funds may come from your own money, gifts, or tribal, state, or local funds awarded to you. Eligible homes are one to four units.
How Assistance Fills the Minimum
Across the wholesale programs Lendmire places files with, there are four shapes of assistance. Each is a percentage of price or value, and each sits under a government first mortgage. You can see the full lineup on Lendmire’s down payment assistance programs page. Here is how each one behaves with condos and multi-unit homes.
| Shape | Size | Repay? | Units | Pairs with |
|---|---|---|---|---|
| Grant | 2% or 3.5% of price | Nothing to repay | 1-4 | FHA only |
| Forgivable second | 3.5% of price or value | Forgiven over 36 or 60 payments | 1-2 | FHA, USDA, HUD-184 |
| Repayable second | 3.5% or 5% | Yes, balloon in year 10 | 1-2 | FHA, USDA, HUD-184 |
| Refinance-cost second | 1% to 3.5% of balance | Yes | 1-4 | FHA refinance |
The grant option is the only one that reaches 3- and 4-unit buildings for a purchase. The grant is released at closing and puts no lien on the property. It covers part of FHA’s 3.5% minimum, either 2% or 3.5% of the price, so at the top tier it can cover the whole minimum. Eligibility is any one of the following: household income at or below 140% of area median income, a first-responder, educator, medical, civil-servant, or military category, first-time-buyer status, or a home in an underserved census tract. It requires a credit score of at least 620 and an HUD-approved homebuyer education course. It is not offered in Washington.
The forgivable second is 3.5% of the lesser of price or value. It carries no interest and no payment, and it is forgiven after 36 or 60 on-time first-mortgage payments. The credit floor is 640. It does not require a first-time buyer, and it has no income limit beyond USDA’s own on a USDA first mortgage.
The repayable second is a real loan. It can be 3.5% or 5%. At 5%, it covers the 3.5% minimum plus 1.5% toward closing costs and prepaid items. It has a monthly payment, a 30-year amortization, and a balloon due in year 10. The credit floor is 660. It carries its own loan disclosures.
None of these stack with another assistance program, and a mortgage credit certificate is not allowed with the second liens.
Why a Forgivable Second Is Not a Gift
This distinction trips up many buyers and agents. A forgivable second feels like a grant, but it is not one. FHA’s handbook treats any financing that creates a lien as secondary financing, even if no payments are due. A true grant or gift leaves no lien behind.
Why it matters: different documents follow from each. A grant needs a commitment letter and evidence of the source. A second lien needs a note, a recorded deed of trust, and compliance with the second-lien conditions. For government-provided secondary financing, FHA’s rules bar cash back to the borrower at closing, with narrow exceptions like earnest money refunds. They also bar a balloon payment within 10 years.
Source matters too. When a government entity funds part of the minimum, the lender has to document that the money legally belonged to that entity. The handbook accepts a draw authorization or a signed letter from an authorized official. This is the paperwork behind the statement “assistance can fill the minimum.” Only qualifying sources do, and the file has to prove it.
Condos: The Building Is the Gate
HUD’s condominium page is plain on this: the unit must sit in an FHA-approved project or qualify for Single-Unit Approval. Assistance does not change that.
SUA has its own rules. The project must be complete and ready for occupancy, with at least five dwelling units, and it cannot be a manufactured home. It must also pass a subset of the full approval tests: FHA concentration, owner-occupancy, and financial condition. Per FHA Connection’s condo help, SUA concentration is capped at 10% of units in projects with ten or more units. Projects with fewer than ten units may have at most two FHA-insured units. The lender submits Form HUD-9991 when requesting the FHA case number.
Think of it as a seat count. If the building has already used its FHA seats, no new FHA buyer can get in, with or without assistance.
Full project approval has its own thresholds. A trade-association summary of HUD’s final rule puts owner-occupancy at 50% (HUD can approve as low as 35% for older projects with low arrears) and maximum FHA concentration at 50%. NAR’s assessment is older, so confirm current levels with HUD. HUD’s project questionnaire counts a unit as owner-occupied if the owner lived there part of the year and did not rent it for most of the year. Units still held by a developer do not count. A brand-new building with many unsold units can fail the occupancy test.
For USDA, condo eligibility rides on another agency’s standards. HOA dues count in your debt-to-income ratio, which matters when a condo’s monthly dues are high.
Multifamily: Three Units Changes the Math
Duplexes are straightforward. Assistance is available on 1-2 unit homes across the second-lien options, and the grant reaches up to four units.
Three- and four-unit buildings add the self-sufficiency test. The property’s projected rent, discounted by FHA for vacancy and costs, must cover the full housing payment. Ask your lender how the exact formula applies to your file.
Here is the buyer-level point. Assistance can fill the minimum investment, but it does not change the test. A bigger first mortgage or a higher housing payment makes the test harder to pass. And rental income from the other units helps the building pass this test, but it never substitutes for the minimum investment.
One caution on timing: a repayable second adds a monthly payment and counts toward debt-to-income. Forgivable and grant structures generally do not add a payment. Ask early which one your loan officer is modeling.
Where the Rules Break
A handful of named edge cases cause most of the surprises.
- Concentration limits. An unapproved building near its FHA cap shuts the door for the next FHA buyer.
- Developer-held units. New or partly sold projects can fail the occupancy test.
- USDA soft seconds. USDA generally caps total liens at market value, but allows the overage when a down payment or closing-cost soft second creates it.
- USDA and old silent seconds. USDA says an existing silent second cannot be rolled into a newly refinanced guaranteed loan. It must be paid off or stay subordinate. Think about the exit before you take the second.
- HUD-184 and assistance. The guarantee itself offers none. Buyers look to a tribe or state housing agency.
- Condo approval can lapse. Project approval is time-limited, so a building on last year’s list may not be on this year’s.
- Recapture. Forgivable help is only a gift if you stay through the term. An early sale, refinance, or move-out can trigger repayment of the unforgiven portion.
Beyond the Minimum
The agency minimum is a floor, not your cash to close. Closing costs and prepaid items are separate. The 5% repayable option is built to cover both. Other options cover the minimum only. Ask which one your file is modeling. The same goes for reserves, if your lender requires them.
Public programs vary widely. Many cap assistance, and some add recapture periods. According to Urban Institute research, nearly 90% of government DPA programs are second mortgages, and just over half of those offer some forgiveness. Those are national patterns, not the terms of any one program.
A Pre-Offer Checklist
Run these in order before you write an offer.
1. Is the property an owner-occupied primary residence you will live in? 2. For a condo, is the project FHA-approved, or does it qualify for SUA? Ask the lender to check concentration and owner-occupancy. 3. For 3-4 units, will projected rent pass the self-sufficiency test? 4. Which assistance shape fits, and does your credit score meet its floor (620, 640, or 660)? 5. Is the assistance a lien? If so, what are the repayment or forgiveness terms? 6. Does it cover the minimum only, or closing costs too? 7. Have condo dues been counted in your monthly budget?
An HUD-approved housing counselor can help you think through the tradeoffs.
Frequently Asked Questions
Do I need any of my own money if I use down payment assistance?
Sometimes, and it depends on the shape. The grant at 3.5% can cover FHA’s whole 3.5% minimum, and a repayable second at 5% adds closing costs. Other combinations leave a gap. Closing costs, reserves, and any program-specific contribution are separate, and every file is underwritten individually.
Does assistance work on a condo that is not FHA-approved?
Only if the unit qualifies for Single-Unit Approval. That requires an unapproved but complete building with at least five units, within the concentration and occupancy limits. If the building fails, assistance cannot rescue the deal.
Can I use assistance on a triplex or fourplex?
For a purchase, the grant option reaches 1-4 units on an FHA first mortgage. The forgivable and repayable seconds cover 1-2 units. On FHA, a 3-4 unit building must also pass the self-sufficiency test. You must live in one unit as your primary home.
Is a forgivable second the same as a grant?
No. A forgivable second is a lien until it is forgiven, after 36 or 60 on-time first-mortgage payments. A grant has nothing to repay and leaves no lien. FHA treats them differently for documentation.
Do I have to be a first-time buyer?
No. Repeat and move-up buyers qualify across the options. First-time status is only one of several categories that satisfy the grant’s eligibility test, and the second-lien options have no income limit beyond USDA’s on a USDA first mortgage.
