The Quick Read: FHA loan CLTV and second lien rules come down to one idea: combined loan-to-value counts the first mortgage plus every second lien on top of it. A grant creates no lien, so it adds nothing to the combined number. A forgivable or repayable second is a real loan, so it counts. Who provides the second, and how it is structured, decides whether the file works.
What Is CLTV and How Is It Different From LTV?
CLTV is combined loan-to-value. LTV looks at the first mortgage only. CLTV adds the balance of every subordinate mortgage to the base loan, then divides by the adjusted value of the home.
HUD’s Handbook 4000.1 glossary defines it that way. It also defines the base loan amount as the mortgage before any financed upfront mortgage insurance premium. That detail matters. The 1.75% upfront premium rides on top of the base loan, but it is left out of the base when the file is measured.
So a buyer can have an FHA first lien at 96.5% leverage and still carry a second lien behind it. The first lien stays inside FHA’s limits. The second is measured separately and then added in. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
How Does the Minimum Investment Fit In?
FHA requires a 3.5% minimum required investment. The same glossary describes it as the borrower’s contribution in cash or its equivalent, at least 3.5% of the property’s adjusted value. Assistance can fill that gap, but only from permitted sources.
That is the whole reason this topic exists. A buyer with thin savings can meet the 3.5% with a grant, or with a second lien from an approved provider. The first lien does the heavy lifting. The assistance covers the rest.
Nobody has to be a first-time buyer to use it. Repeat and move-up buyers qualify across the wholesale programs Lendmire places files with. The assistance is for an owner-occupied primary residence only. Never a second home, never a rental.
Four Shapes of Assistance (and What Each Does to CLTV)
Across the wholesale programs Lendmire arranges, assistance comes in four shapes. Here they are side by side, then in detail.
| Shape | Lien? | Amount | Repayment |
|---|---|---|---|
| Grant | No | 2% or 3.5% of price | Nothing to repay |
| Forgivable second | Yes | 3.5% of lesser of price or value | Forgiven after 36 or 60 payments |
| Repayable second | Yes | 3.5% or 5% | 30-year amortization, balloon in year 10 |
| Refinance-cost second | Yes | 1% to 3.5% of balance | Same terms as repayable |
All figures are through wholesale lenders, subject to program guidelines and full underwriting.
The grant: nothing to repay
The grant covers 2% or 3.5% of the purchase price toward the FHA minimum investment. It is released at closing. No lien, no payment, no interest. Because there is no lien, CLTV stays equal to the first-lien leverage.
The credit floor is 620, and the first lien must be FHA. The income test is household income at or below 140% of area median income. That test is waived for several groups: first responders, educators, medical workers, civil servants, military personnel, first-time buyers, and buyers in an underserved census tract. An HUD-approved homebuyer education course is required. The grant is not offered in Washington, and it cannot combine with any other assistance program.
The forgivable second: a lien that goes away
This is 3.5% of the lesser of price or appraised value. No interest and no monthly payment. After 36 or 60 on-time first-lien payments, with no 90-day delinquency, the balance is forgiven.
It is still a lien while it exists. It counts toward CLTV. The credit floor is 640, or 660 on a blended score. It pairs with FHA, USDA, or HUD-184 first liens on one-to-two-unit homes. There is no income limit beyond USDA’s own on a USDA first lien.
Public agencies run similar structures. NJHMFA is one example of a forgivable second paired with an agency first mortgage.
The repayable second: a real loan
This one is 3.5% or 5% of the lesser of price or value. At 5%, it also covers closing costs and prepaid items (3.5% for the minimum investment, plus 1.5% toward closing costs). It carries interest, a monthly payment, a 30-year amortization, and a balloon due in year 10. It gets its own disclosure, including a balloon disclosure.
Credit floor is 660, or 670 blended. High-balance first liens are allowed. Manual underwriting is not. The payment counts in the debt-to-income ratio. That is the main cost of the structure.
The refinance-cost second
On an FHA 203(b) refinance, a second lien of 1% to 3.5% of the balance can cover closing costs, with combined leverage up to 104%. It is not for streamline refinances, and it cannot refinance an existing assistance loan. Credit floor is 660, or 670 blended. Every figure here varies by lender and program, since guidelines, property type, leverage, and credit profile all apply.
How the Second Lien Is Underwritten, Step by Step
The mechanics are the same pattern on every file.
1. First lien. The buyer gets an FHA, USDA, or HUD-184 first mortgage. FHA measures the base loan amount, not the financed premium.
2. Pick the structure. Grant, forgivable second, or repayable second, based on credit, income, and cash position.
3. Add the second to CLTV. The second lien’s principal counts. A grant counts for nothing.
4. Check the provider. For FHA, a government provider must be a real governmental entity or instrumentality, or an HUD-approved nonprofit. The glossary spells out both definitions.
5. Underwrite payment capacity. A repayable second adds a monthly payment to DTI. A forgivable second usually does not, but it is still a debt. The AUS finding drives the ratios.
6. Document the second. The file needs the note, the security instrument, and a subordination agreement so the first stays in first position. Gift or source-of-funds paperwork comes along if any cash is involved.
7. Close and record. The second is recorded behind the first. The program’s occupancy and repayment terms live in the note and deed, not in FHA rules.
HUD’s exact rules on secondary financing sit in Handbook 4000.1. Lenders must confirm the provider qualifies under it. The rules on how much combined leverage is allowed can differ by provider type, so a lender confirms that before the deal works.
Where the General Rule Breaks
USDA is not a CLTV program
Do not apply FHA’s framing to USDA. USDA’s closing chapter requires the guaranteed loan to be in first-lien position when recorded. The title policy or attorney opinion must list the other liens and show them as subordinate. The cap is 100% of appraised value plus the upfront guarantee fee.
Assistance works there because the guaranteed loan stays first.
On a USDA refinance, an assistance second cannot be rolled into the new loan. It has to be subordinated or paid off.
HUD-184 has no built-in assistance
The Section 184 program guarantees loans. It does not lend or give grants. Tribal or other assistance comes from outside the program, as a junior lien that meets HUD’s conditions. Many tribal programs use forgivable seconds. Underwriting is manual, and the borrower must be an enrolled member of a federally recognized tribe.
Seller and family money
Seller and agent money cannot fund the minimum investment. Family seconds are treated differently from government seconds, and the combined limit is tighter. Those are lender-confirmed points, so ask before relying on a gift-plus-second plan.
Old documentation rules
In 2019, FHA issued a letter requiring extra documentation of a government provider’s authority. A court fight followed, the rule was suspended, and it was later rescinded. Do not assume those rules are in force. A lender still has to confirm the provider qualifies.
Stacking
Nothing stacks. No option combines with another assistance program. A mortgage credit certificate is not permitted with the second-lien options. Many public programs also only work with their own agency’s first mortgage, so the pairing is part of the program.
Common Reasons a Combo Loan Stalls
- The second-lien provider is not an approved source.
- Cash back at closing.
- A missing or unsigned subordination agreement.
- A score below the option’s floor. Each shape has its own.
- Manual underwriting on a repayable second, which does not allow it.
- A property type outside the matrix, or a unit count too high for the option.
- Counseling not finished on the grant.
Most of these are paperwork, not credit. A clean file lists the second lien up front, so nothing surprises the underwriter late.
What the Decision Looks Like in Practice
Picture a renter buying a first home with little saved. The grant often fits best: nothing to repay, no payment, and CLTV stays at the first-lien level. If income runs over 140% of area median, a qualifying category may still carry the file.
Now a repeat buyer who sold a home three years ago. No grant category fits by first-time status, so the forgivable second is the natural fit. No income test, no payment, and forgiveness after 36 or 60 on-time payments.
Finally, a buyer who also needs closing costs covered. The repayable second at 5% does both jobs. The trade is a monthly payment and a year-10 balloon, so the buyer should plan for a sale, a refinance, or a payoff before then.
A few cost points apply to any lien. The second must be repaid or subordinated if the buyer refinances. Selling early can trigger repayment of the unforgiven part. Some seconds accrue interest even when payments are deferred.
Independent advice helps. HUD-approved counselors are listed through the CFPB counselor search.

Frequently Asked Questions
Does a grant change my CLTV?
No. A grant creates no lien, so nothing is added to the combined number. CLTV stays equal to the first-lien leverage. A forgivable or repayable second does count, because it is a loan recorded behind the first.
Do I have to be a first-time buyer?
No. Repeat and move-up buyers qualify under the assistance options Lendmire arranges. First-time status is only one of the categories that waives the grant’s income test. The home must be an owner-occupied primary residence.
Does the second lien raise my monthly payment?
It depends on the shape. A repayable second adds a monthly payment that counts in DTI. A forgivable second has no payment and no interest, but it is still a lien until it is forgiven. Terms are subject to program guidelines and full underwriting.
Can I use assistance with a USDA or HUD-184 loan?
Yes, for the forgivable seconds with either loan, and for the repayable second with USDA only. The grant pairs with FHA first liens only. On USDA, the guaranteed loan must stay in first position. HUD-184 supplies no assistance itself, so it comes from an outside source.
What happens if I refinance or sell?
The second lien must be paid off or subordinated. On a forgivable second, selling or refinancing before forgiveness can trigger repayment of the unforgiven part. A repayable second comes due at sale, payoff, or the year-10 balloon.
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.
