Reserves

Also called Cash reserves, Months of reserves, PITI reserves, Post-closing reserves.

By AAA Capital Funding, Inc.Reviewed by Jason J. Sarji, NMLS #374700Updated October 21, 2026
In plain wordsReserves are the savings you still have after paying the down payment and closing costs, measured in how many months of the new house payment they would cover.

Reserves are what's left in your accounts the day after closing. Lenders count them in months: one month of reserves equals one full house payment, including principal, interest, taxes, insurance, mortgage insurance and HOA dues. A lender that asks for 3 months wants to see enough savings to make three payments with no paycheck at all.

Counting your months

Take a $330,000 single-family FHA purchase with a $2,563.12 monthly payment. The buyer has $17,600 in savings and needs $13,250 at closing ($11,550 for the 3.5% down payment plus $1,700 in costs the seller credit didn't cover).

$17,600 minus $13,250 leaves $4,350. Divided by $2,563.12, that's 1.70 months of reserves, which is more than FHA asks for on this loan.

What each program asks for

ProgramReserves required
FHA, 1 or 2 units, automated approvalNone set by FHA; the findings may ask for some
FHA, 1 or 2 units, manual underwriting1 month
FHA, 3 or 4 units3 months
ConventionalSet by Desktop Underwriter; 6 months on a 2 to 4 unit home
VA, 2 to 4 units6 months when rent from the other units is used to qualify
USDANo reserve requirement

Even when a program doesn't require them, reserves strengthen an approval. On a manual FHA loan, 3 months on a 1 or 2 unit home counts as a compensating factor that raises the ratio limits.

A triplex buyer, before and after a gift

A buyer is purchasing a $450,000 triplex with FHA. The monthly payment is $3,543.79, so FHA's 3 months of reserves comes to $10,631.37. The buyer has $21,500 saved, and the seller credit covers closing costs.

Buyer pays the down paymentFamily gift pays the down payment
3.5% down payment$15,750 from savings$15,750 from the gift
Savings left after closing$5,750$21,500
Months of reserves1.626.07
Meets FHA's 3 monthsNoYes

FHA doesn't count gift money as reserves, but it does allow a gift for the down payment. Using the gift for the down payment leaves the buyer's own savings in place to count as reserves.

Where reserves can come from

Checking, savings and money market balances count in full. Stocks, bonds and vested retirement funds count too, sometimes at a reduced percentage. Lenders usually want two months of statements, and a large deposit that isn't from payroll needs a paper trail. Money that's borrowed, such as a cash advance or personal loan, doesn't count.

The cash to close calculator shows what you'll bring to the table, and whatever is left in savings is your reserves. If you're buying a 3 or 4 unit home, call AAA Capital Funding at 888-601-8344 and we'll set up the gift, seller credit and savings so the reserves line up before you make the offer.

Common questions

Do I need reserves for an FHA loan on a single-family home?
Usually not when the automated system approves the loan. FHA requires reserves on 3 and 4 unit homes (3 months) and on manually underwritten loans (1 month on 1 and 2 units), and extra reserves can count as a compensating factor.
Can retirement savings count as reserves?
Yes. Vested balances in a 401(k) or IRA can count toward reserves, though lenders may count only part of the balance to allow for taxes and penalties. You don't have to withdraw the money.
