The Quick Read: A strong income and a large student-loan balance do not automatically rule you out. Two separate tests decide your file. One checks your income against the assistance option. The other turns your student loans into a monthly number inside your debt-to-income ratio. You can pass one and fail the other, so check them in that order.
Key Takeaways
- Income is tested by the assistance option. Student debt is tested in underwriting.
- Nobody has to be a first-time buyer. Repeat and move-up buyers qualify.
- The second-lien options carry no income limit of their own. The grant has an income test, unless you fit a qualifying category.
- Deferred and forgiveness-track student loans still count against you in underwriting.
- Assistance applies to an owner-occupied primary residence only. A rental or second home is not eligible.
Two Gates, Not One
A high earner usually clears the assistance gate more easily than expected. The harder gate is the student-loan math. The assistance option asks who you are and what you earn. The first mortgage asks whether your monthly obligations leave enough room for a new housing payment.
Most buyers assume a six-figure income ends the conversation. It does not. Among the down payment assistance programs a broker can arrange through wholesale lenders, only one shape applies an income test at all. Even that one has exceptions.
Here is how a file moves, start to finish:
1. You pick the assistance shape that fits your situation. 2. The lender runs full underwriting on the first mortgage. That is an FHA, USDA or HUD-184 loan. 3. Your student loans are converted into a monthly figure. 4. A repayable second lien, if you use one, adds its own payment. 5. The file is checked against program guidelines, credit floors and the automated underwriting finding.
Everything below walks through those steps. Program terms change, and every file is underwritten individually, subject to lender guidelines. Nothing here is a commitment to lend.
Key Terms Defined
Debt-to-income ratio (DTI): Your monthly debts, including the new housing payment, divided by your gross monthly income.
First lien: The main mortgage. It gets repaid first if the home is sold or foreclosed.
Second lien: A smaller loan recorded behind the first mortgage. It is a real loan, even when no payment is due for years.
Forgivable: Fully written off if you make the required number of on-time first-mortgage payments.
Balloon: A lump-sum balance that comes due at a set point, even though payments were calculated over a longer term.
Area median income (AMI): The middle household income for your county. Programs use it to set income tests.
What Are the Four Shapes of Assistance?
Down payment assistance comes in four shapes: a grant, a forgivable second lien, a repayable second lien, and a refinance-cost second lien. Each pairs with a government-backed first mortgage. Percentages below are of price or value, never a dollar promise. Availability runs through wholesale lenders, subject to program guidelines and full underwriting.
| Shape | Size | Repaid? | Credit floor |
|---|---|---|---|
| Grant | 2% or 3.5% of price | Nothing to repay | 620 |
| Forgivable second | 3.5% of price or value | Forgiven after 36 or 60 payments | 640 |
| Repayable second | 3.5% or 5% of price or value | Yes, 30-year schedule, balloon in year 10 | 660 |
| Refinance-cost second | 1% to 3.5% of balance | Yes, same terms as repayable | 660 |
The grant is released at closing. There is no lien, no payment and no interest. It works with FHA first liens only, at 96.5% loan-to-value, on one to four units. A homebuyer education course is required. It is not offered in Washington.
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 delinquency of 90 days or more. It pairs with FHA, HUD-184 and USDA first liens on one to two units. Manual underwriting is allowed. No homebuyer counseling is required.
The repayable second is a loan. It bears interest, has a monthly payment, amortizes over 30 years and balloons in year 10. At 5%, it also covers closing costs and prepaids. It pairs with FHA, HUD-184 and USDA first liens. It requires an automated approval, and manual underwriting is not allowed.
The refinance-cost second covers closing costs on an FHA refinance, with combined leverage up to 104%. It never applies to a streamline refinance. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Where a score is shown as blended, a lower-scoring co-borrower can be averaged in. This works when the primary wage earner brings in at least 60% of household income and holds the higher score. The minimums become 660 for the forgivable second and 670 for the repayable one.
Do You Earn Too Much?
Usually not. Three of the four shapes have no income test at all, and the fourth has several ways around it. The one exception is a USDA first lien, because USDA caps household income itself.
The grant is often a strong option with an income test. Your household income must be at or below 140% of the area median, unless you fit a qualifying category. Any one of these is enough:
- A first responder, current, former or entering service.
- An educator.
- Medical personnel, from nurses and doctors to hospital workers.
- A civil servant at the federal, state or local level.
- Military personnel, current, retired, volunteer or unpaid.
- A first-time buyer, meaning no ownership interest in a home for three years.
- A buyer purchasing in an underserved census tract.
So a high earner who teaches, nurses or serves can qualify at nearly any income. A high earner outside those groups can still use a forgivable or repayable second, which carry no income limit of their own.
USDA is different. It sets a hard income cap by county and household size. USDA’s guaranteed-loan rules define moderate income relative to area medians. On USDA, every adult’s income counts toward the cap, while only borrowers’ income counts toward repayment. A buyer can have a low DTI and still fall outside the cap.
One more point on stacking. The rules vary by option, and the program parameters do not support a blanket statement that nothing combines with another assistance program. A mortgage credit certificate is not permitted with the second-lien options.
How Do Lenders Count Your Student Loans?
Every student loan counts, whatever its status. Deferred, in forbearance or on an income-driven plan, it still lands in your DTI. The payment used is the one on your credit report or servicer statement, as long as it is above zero. If the reported payment is zero, the lender uses a percentage of the balance instead.
That is the FHA rule. HUD’s FHA guidance states it plainly. A 2021 HUD mortgagee letter required lenders to include all student loans regardless of payment type or status. HUD has since folded that letter into its Single Family Handbook, which is the current source. Confirm the present wording with your lender, because handbooks get updated.
Older blogs still say FHA uses 1% of the balance. That was replaced.
USDA lands in the same place. Its Chapter 11 underwriting rules use the documented payment when it is above zero, or 0.5% of the balance when it is zero, regardless of status. USDA’s loan-origination FAQ adds that a $0 income-based payment still counts at 0.5%. A loan in deferment still counts. A loan headed for forgiveness still carries a payment in the ratios until it is released.
On manual FHA underwriting, the standard ratios are 31/43. Automated approvals commonly allow more, and the assistance options follow the automated finding.
Worked Scenario: The Zero-Payment Trap
Picture a physician-level earner whose student-loan balance equals about a year of gross pay. She is on an income-driven plan, and her servicer reports no required monthly payment.
The lender does not read that as $0. It counts 0.5% of the balance every month. A balance equal to twelve months of income produces a monthly obligation of about 6% of her gross monthly income. That is six points of DTI before the new mortgage payment is counted.
Now picture her neighbor. His balance is the same, but his servicer reports an actual payment. That payment counts at face value. Depending on the plan, it can be higher or lower than the 0.5% figure.
A commonly cited fix is getting a documented, non-zero payment from the servicer before applying. Whether that works depends on the lender and the underwriter, so ask first. A $0 report is not a free pass, and it can be the worse number.
Then add the assistance. If she uses the grant or a forgivable second, no new monthly payment appears. If she uses a repayable second, a separate payment joins the housing costs. That difference alone can decide which shape fits.
Where the General Rule Breaks
- High income plus USDA. A low DTI does not cure an income above the cap.
- A parent pays your loan. On USDA, loans in your name still count unless the lender documents otherwise. Ask how the FHA lender will treat it.
- A non-borrowing spouse. On USDA, that income counts toward the cap but not toward repayment income.
- Forgiveness plans. The balance stays in the ratios until it is released.
- Repeat buyers. They qualify. The first-time definition is just one of the grant’s qualifying categories.
- Second homes and rentals. Not eligible. Assistance is for an owner-occupied primary residence only.
- Grant versus second. The same dollars can be a gift or a loan, depending on whether a mortgage or only a retention agreement is recorded. A recorded mortgage counts as secondary financing.
- Funding. Many public programs cap assistance or add recapture periods. The ones Lendmire arranges follow their own terms.
What Does Each Shape Really Cost You?
The grant costs you the least over time. The repayable second costs you the most. That is the honest comparison.
The grant has nothing to repay. Its cost is eligibility: the credit floor, the course, and the income test or category.
The forgivable second has a different cost, which is time. You keep making on-time first-lien payments for 36 or 60 months. Miss that window and the balance may come due. Check how a sale or refinance would affect it.
The repayable second is a loan. It carries interest, a payment and a balloon in year 10. Plan for that date. Many buyers sell or refinance before it arrives, but a plan beats a hope.
The first mortgage has its own costs under all of them. FHA charges an upfront mortgage insurance premium, which can be financed. It also charges annual mortgage insurance that varies by loan size and leverage. FHA allows 96.5% first-lien leverage, with a minimum investment of 3.5% of the lesser of price or appraised value.
What Should a High Earner Do Next?
Fix the student-loan number first, then pick the shape. The loan payment is the part you can influence before applying.
1. Pull your credit report and servicer statements. Find the payment each loan reports.
2. Ask whether any loan reports $0. Ask the servicer for a documented payment if your plan allows one.
3. Check your category. If you teach, serve, nurse or work in public service, the grant’s income test may not apply to you.
4. Decide how much monthly room you have. If it is thin, lean toward the grant or the forgivable second. A repayable second adds a payment.
5. Plan your documents: credit report, servicer letters, income documents, your assistance approval, the occupancy affidavit and, for the grant, your education certificate.
6. Ask the lender how the second lien fits the first lien’s combined-leverage rules.
If you are a strong saver, assistance may not be your best tool. A larger down payment from your own funds avoids a second lien. If cash is the bottleneck and your income is strong, assistance can bridge the gap. It is a genuine toss-up for many buyers, and the student-loan math often decides it.
Frequently Asked Questions
Do student loans disqualify me from down payment assistance?
No. They are counted in your DTI, not screened out. The payment on your credit report is used, or 0.5% of the balance if it reports $0. A high balance can shrink the price you qualify for, but it does not close the door.
Do I have to be a first-time buyer?
No. Repeat and move-up buyers qualify for all four shapes. The first-time definition is only one of several categories that can waive the grant’s income test.
Can I use assistance on a rental or second home?
No. Assistance applies to an owner-occupied primary residence only.
Is the assistance free?
Not in every shape. The grant has nothing to repay. The forgivable second is a loan that is forgiven after on-time payments. The repayable second is an interest-bearing loan with a balloon in year 10.
Can I combine assistance with another program?
Not necessarily. Stacking rules depend on the specific program and lender, so confirm with the program administrator before assuming two forms of assistance can be combined. A mortgage credit certificate is also not permitted with the second-lien options.
