You can use a loan for a down payment only if the loan is secured by an asset you already own. Unsecured personal loans and credit card cash advances are off the table for conventional, FHA, and USDA mortgages. Borrowing against a 401(k), a home you already own, a certificate of deposit, or the cash value of a life insurance policy is generally fine, because that money represents a return of your own equity rather than new unsecured debt piled on top of the mortgage.
Unsecured Loans Are Not Allowed
Fannie Mae’s selling guide states plainly that personal unsecured loans are not an acceptable source of funds for a down payment, closing costs, or reserves.1Fannie Mae. B3-4.3-17, Personal Unsecured Loans FHA rules match this, listing unsecured signature loans, credit card cash advances, and loans against household goods as explicitly unacceptable funding.2U.S. Department of Housing and Urban Development. FHA Single Family Housing Policy Handbook USDA guaranteed loans also bar unsecured borrowed funds for reserves or funds to close.3USDA Rural Development. FAQ – Rural Development Single Family Housing Guaranteed Loan Program Origination
The reasoning is simple. Lenders want you to have real equity in the property from day one. A down payment funded by a 15% personal loan would leave you with no equity at closing and two competing monthly payments, a combination that historically produces higher default rates.
Secured Loans That Lenders Accept
Fannie Mae explicitly allows borrowed funds when they’re secured by an asset, because those funds trace back to your own equity. Acceptable collateral includes financial assets like savings accounts, CDs, stocks, bonds, and 401(k) accounts, along with non-financial assets like real estate, automobiles, artwork, and collectibles.4Fannie Mae. B3-4.3-15, Borrowed Funds Secured by an Asset
401(k) Loans
A 401(k) loan lets you borrow the lesser of 50% of your vested balance or $50,000.5Internal Revenue Service. Retirement Topics – Loans If 50% of your vested balance is under $10,000, you can still borrow up to $10,000.6Internal Revenue Service. Borrowing Limits for Participants With Multiple Plan Loans Because you’re borrowing from yourself, lenders treat these funds differently from bank-issued personal debt. Most 401(k) loans must be repaid within five years, though loans used to buy a primary residence can have a longer repayment window.7U.S. Department of Labor. FAQs About Retirement Plans and ERISA
Watch the job-loss risk. If you leave your employer before repaying the loan, the outstanding balance typically becomes due much sooner, and missing that deadline can trigger income taxes plus an early withdrawal penalty on the unpaid amount.
Home Equity Lines of Credit
If you already own property, a HELOC against it is an accepted down payment source. The borrowed money is secured by real estate, so underwriters treat it as legitimate equity. The HELOC’s monthly payment will count toward your debt-to-income ratio for the new mortgage, which can shrink the loan amount you qualify for.
Loans Against Life Insurance or a CD
Borrowing against the cash value of a life insurance policy or against a certificate of deposit works the same way. The lender sees collateral with a clear cash value, and the interest rates tend to run lower than unsecured alternatives because the lender’s risk is minimal.
How the Rules Differ for FHA, VA, and USDA Loans
Every government-backed program rejects unsecured borrowing, but the down payment picture varies.
FHA
FHA borrowers need a minimum down payment of 3.5%. The FHA handbook allows collateralized loans from independent third parties for that down payment, so you can borrow against your own financial assets or real estate to cover it. Unsecured signature loans, credit card advances, and loans against household goods are all barred. FHA also permits secondary financing from family members toward the minimum required investment, as long as the first mortgage keeps its senior lien position.2U.S. Department of Housing and Urban Development. FHA Single Family Housing Policy Handbook
VA
VA-guaranteed loans generally require no down payment, so the borrowed-funds question is moot for most VA borrowers.8Veterans Benefits Administration. VA Home Loan Guaranty Buyer’s Guide A down payment may be needed when the purchase price exceeds the appraised value. Gift funds are accepted, and VA rules allow secondary financing in some scenarios provided the VA loan stays in the senior lien position.
USDA
USDA guaranteed loans also feature a zero-down-payment structure, so most borrowers face no down payment gap. The program specifically prohibits unsecured borrowed funds for reserves or funds to close. Gifts from any uninvolved third party are allowed, and down payment assistance programs can be layered in as long as the USDA loan holds first lien position.3USDA Rural Development.

Alternatives to Borrowing
If tapping your own assets isn’t attractive, three routes let you close the down payment gap without taking on unsecured debt.
Down Payment Assistance Programs
Hundreds of state and local programs offer help, generally in one of three forms: outright grants that never need to be repaid, deferred-payment second mortgages (often called soft seconds) that require no payments until you sell or refinance, and standard amortizing second mortgages with regular monthly payments. Many soft-second programs forgive the balance after you stay in the home for a set period, sometimes as short as two years.9FDIC. Down Payment and Closing Cost Assistance Eligibility and income limits vary, so check your state housing finance agency for current programs.
Piggyback Loans
A piggyback loan, sometimes called an 80/10/10, splits the deal into a first mortgage covering 80% of the home’s value, a second mortgage covering 10%, and a 10% down payment from the buyer. The second mortgage carries a higher rate than the first. The structure is designed to avoid private mortgage insurance rather than eliminate a down payment, but it does reduce cash needed upfront. Lenders typically want a credit score of at least 680 and a combined DTI under 36%.
Gift Funds
Gift money is the cleanest way to cover a shortfall without any borrowing. On a conventional loan for a primary residence, Fannie Mae does not require any minimum contribution from the borrower’s own funds, even at higher loan-to-value ratios. The entire down payment can come from a gift.10Fannie Mae. B3-4.3-04, Personal Gifts Every lender will require a gift letter from the donor confirming no repayment is expected, plus bank statements showing the donor had the money and transferred it to you. If the underwriter suspects the “gift” is actually a disguised loan, the funds get treated as borrowed and can sink the application.
How a Borrowed Down Payment Affects Approval
Even when the borrowing is allowed, it creates a new monthly obligation the underwriter may fold into your debt-to-income ratio. How much it stings depends on what’s securing the loan.
Loans secured by financial assets get favorable treatment. Fannie Mae’s guidelines state that monthly payments on loans secured by financial assets like a 401(k), CD, or investment account do not have to be counted as long-term debt.4Fannie Mae. B3-4.3-15, Borrowed Funds Secured by an Asset That’s what makes a 401(k) loan one of the least disruptive ways to fund a down payment: the monthly repayment stays off your debt column, though the lender will reduce the value of the corresponding asset by the loan amount.
Loans secured by non-financial assets are treated differently. If the collateral is real estate (a HELOC) or an automobile, the monthly payment must be counted as a recurring debt obligation.4Fannie Mae. B3-4.3-15, Borrowed Funds Secured by an Asset A $400 HELOC payment on top of your existing debts could meaningfully reduce how much mortgage you qualify for.
For conventional loans underwritten through Fannie Mae’s automated system, the maximum DTI is 50%. Manually underwritten loans start at 36% and can stretch to 45% when the borrower meets specific credit score and reserve thresholds.11Fannie Mae. B3-6-02, Debt-to-Income Ratios FHA and VA loans have their own DTI guidelines. Before borrowing for a down payment through a HELOC or any other loan backed by non-financial collateral, run the numbers to make sure the new monthly payment doesn’t push you past your program’s ceiling.
Why Hiding a Personal Loan Is a Bad Idea
Some buyers are tempted to take out a personal loan, deposit the cash, and hope the underwriter doesn’t spot it. Don’t.
Making a false statement on a mortgage application is a federal crime under 18 U.S.C. ยง 1014, with a maximum penalty of 30 years in prison and a $1,000,000 fine.12Office of the Law Revision Counsel. 18 U.S. Code 1014 – Loan and Credit Applications Generally The statute covers any knowingly false statement made to influence a federally related mortgage lender, which includes essentially every bank, credit union, and mortgage company in the country. Concealing a loan that provided your down payment qualifies.
For FHA-insured loans, the government can also impose civil money penalties on top of criminal prosecution, and the Secretary of Housing can refer the case to the U.S. Attorney General for enforcement in federal court.13Office of the Law Revision Counsel. 12 USC 1735f-14 – Civil Money Penalties Against Mortgagees, Lenders, and Other Participants in FHA Programs Even without a criminal case, a lender can rescind the mortgage after closing once fraud surfaces, leaving you without a home and with damaged credit. Underwriters are trained to spot this pattern, and the large-deposit verification rules exist partly to catch it.
