Yes, you can change the down payment amount before closing, but the lender has to approve the new figure, you’ll need to document where the money is coming from, and the change can affect your rate lock, your Closing Disclosure timing, and your contract with the seller. Handled early, it’s routine. Handled in the final days before closing, it can push the settlement date.
Will the New Amount Still Qualify
Any revised down payment has to clear the minimum for your loan program. FHA loans require at least 3.5% of the purchase price.1U.S. Department of Housing and Urban Development (HUD). What Is the Minimum Down Payment Requirement for FHA Conventional conforming loans through Fannie Mae allow as little as 3% down for first-time buyers under the HomeReady or standard 97% loan-to-value programs.2Fannie Mae. 97% Loan to Value Options VA-backed purchase loans often require nothing down, provided the sale price does not exceed the appraised value.3Veterans Affairs. Purchase Loan Jumbo loans above the conforming limit typically require at least 20% down.4Federal Housing Finance Agency. News Releases
The 20% mark matters on conventional loans for a different reason. Drop below it and the lender will add private mortgage insurance, which raises your monthly payment.5Consumer Financial Protection Bureau. What Is Private Mortgage Insurance Move above it and you can shed PMI and, in some cases, earn a lower interest rate.
What Happens to Your Rate Lock
Changing the down payment changes the loan amount, and a rate lock is tied to specific loan terms. The lender may treat that as a material change. The CFPB lists a decision to change the down payment amount among the common reasons a locked rate can change.6Consumer Financial Protection Bureau. What’s a Lock-In or a Rate Lock on a Mortgage
Ask the loan officer up front whether the revised loan amount will disturb your lock. If market rates have risen since you locked, even a modest adjustment could raise the monthly payment. If they have dropped, a new lock might help you, but there’s no guarantee.
Documents the Lender Will Ask For
Before the file can be adjusted, you’ll need to show the money. Fannie Mae’s guidelines require bank statements covering the most recent 60-day period so the underwriter can verify the funds are yours and have been in place long enough to be considered seasoned.7Fannie Mae. Verification of Deposits and Assets Depending on where the money comes from, expect requests for:
- Updated 60-day statements for any bank account you’re drawing from.
- A signed gift letter from the family member providing the funds, along with proof of the transfer.
- Statements showing the sale of stocks, bonds, or mutual funds, plus evidence the proceeds landed in your account.
- Retirement account statements identifying the vested balance and withdrawal terms.
Tell the loan officer the exact dollar figure or percentage you want. Vague requests bounce back through underwriting more than once.
What Underwriting Redoes
Once the documentation is in, the file goes back to the underwriter. They recalculate the loan amount, the loan-to-value ratio, and the debt-to-income ratio to confirm the revised numbers still meet the program’s guidelines and the lender’s own limits.
After the underwriter clears the file, the lender issues a revised Closing Disclosure showing the new loan amount, monthly payment, interest charges, and cash to close. It usually arrives through the lender’s portal or by email. Read it carefully and confirm receipt quickly. The closing timeline does not resume until you do.
Will There Be a New Three-Day Wait
Not every down payment change delays closing. Federal rules require a new three-business-day waiting period only in three situations: the APR becomes inaccurate, the loan product itself changes, or a prepayment penalty is added.8Consumer Financial Protection Bureau. Regulation Z – 1026.19 Certain Mortgage and Variable-Rate Transactions For anything else, a corrected Closing Disclosure just needs to reach you by closing.9Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs
The APR trigger is the one that most often comes into play here. Under Regulation Z, a disclosed APR is inaccurate if it moves by more than 1/8 of 1 percentage point (0.125%) from the actual APR.10Consumer Financial Protection Bureau. Regulation Z – 1026.22 Determination of Annual Percentage Rate A large swing, say from 20% down to 10%, can push the APR past that threshold once PMI and a bigger loan balance are figured in. A small change, from 20% to 18%, likely won’t.
When a Low Appraisal Forces the Change
Sometimes the choice isn’t yours. If the home appraises below the agreed purchase price, the lender will only base the loan on the appraised value. The gap becomes your responsibility unless the seller agrees to reduce the price.
Say you agreed to pay $400,000 with 10% down on a $360,000 loan, and the appraisal returns at $380,000. The lender lends against the $380,000 figure. Keeping the deal at the original price means covering the $20,000 gap on top of your original down payment, bringing your cash contribution to $60,000. If that isn’t available, the options are renegotiating the price, lowering your down payment relative to the appraised value (which may add PMI), or walking away if your contract has an appraisal contingency.
Where the Extra Money Comes From
The source of the additional funds carries its own rules. For 2026, the annual gift tax exclusion is $19,000 per recipient.11Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 A married couple can give $38,000 combined to a single recipient without filing a gift tax return. Above that, the giver files IRS Form 709, though no tax is typically owed unless they’ve exceeded their lifetime exemption.
Retirement funds work differently by account type. A traditional IRA withdrawal for a first-time home purchase is exempt from the 10% early distribution penalty on up to $10,000, though regular income tax still applies.12Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions That exception does not extend to 401(k) plans. A pre-59½ withdrawal from a 401(k) for a down payment brings both income tax and the 10% penalty.
Your Purchase Contract May Need an Amendment
The mortgage is one side of the deal. The purchase contract is the other, and most contracts spell out the financing terms, including loan type, loan amount, and down payment. Change those figures and the seller or the seller’s agent may need to sign a written amendment acknowledging the new terms. It’s usually straightforward, but it takes coordination with your agent and the other side.
If the change pushes closing past the contract date, you may need to ask for an extension. Sellers aren’t obligated to grant one, and in a competitive market a delay can create friction or, occasionally, give the seller grounds to cancel. Tell your lender, agent, title company, and the seller’s agent as early as you can.
