Cash reserves after closing: how much to keep in the bank

What lenders mean by reserves

Fannie Mae's Selling Guide, section B3-4.1-01, defines liquid financial reserves as assets that are available to you after the mortgage closes and that you can turn into cash by withdrawing money, selling an asset, redeeming vested funds or borrowing against an account from a fund administrator or insurer.

The guide measures reserves in months, not dollars. One month is the qualifying payment for the new loan, based on PITIA: principal, interest, property taxes, homeowners insurance and association dues. If your payment will be $2,300 and you will have $23,000 left after closing, you have about ten months of reserves.

The same section says funds needed to close are subtracted first. Money that pays for the down payment or closing costs cannot also count as a reserve.

When reserves are required

The answer depends on the property and the loan. For loans run through Fannie Mae's Desktop Underwriter, the Selling Guide lists these minimums:

Additional reserves apply when you own other financed properties, and DU can also ask you to show funds equal to the balance of accounts that must be paid in full each month. Manually underwritten loans use the reserve figures in Fannie Mae's Eligibility Matrix.

FHA, VA and USDA loans have their own rules, and individual lenders can add requirements, sometimes called overlays. Ask your loan officer what your file needs before you move money around.

What counts and what does not

Fannie Mae's examples of acceptable reserve assets include money in checking and savings, stocks, bonds, mutual funds, certificates of deposit, money market funds, trust accounts, the vested amount in a retirement account and the cash value of a vested life insurance policy.

The same section excludes:

• funds that are not vested
• funds you can withdraw only at retirement, job loss or death
• stock in a company that is not publicly listed, and unvested stock options or restricted stock
• personal unsecured loans
• rent-back credits, seller or other interested-party contributions and lender contributions
• cash from a cash-out refinance on the same property

Eligible gift funds can count toward reserves. A gift of equity cannot.

Reserves for underwriting versus reserves for life

The lender's number is a floor. It answers a narrow question: can this borrower keep paying for a while if income stops? Your own cushion has to handle more than the mortgage. Groceries, utilities, insurance on the car and a surprise water heater all compete for the same dollars.

That is why the calculator gives two figures. The first is months of housing payment, the way a lender counts. The second divides what is left by the housing payment plus your other monthly spending. That second number is closer to how long the money would last in a real emergency.

How to protect your reserve

Use real numbers. The Loan Estimate lists the estimated cash to close, and the CFPB explains how to read it. A rough percentage can be off by thousands.

Separate the move-in budget. Movers, utility deposits, window coverings and a lawn mower are not emergencies, but they will drain the emergency money if they share an account.

Avoid unexplained transfers. Lenders review bank statements and may ask you to document large deposits. Moving money between your own accounts is usually simple to explain, but keep the statements.

Do not borrow to look liquid. Personal unsecured loans do not count as reserves under Fannie Mae's guide, and a new loan can change your debt-to-income ratio.

Keep it accessible. The CFPB's guide to emergency funds suggests a separate account so the money is easy to reach but not mixed with daily spending.

If the reserve looks thin

If the calculator shows only a month or two after closing, you have options before you sign:

• Ask the lender to price a smaller down payment. More cash in the bank may matter more than a slightly lower loan amount, though a smaller down payment can mean mortgage insurance.
• Negotiate seller concessions toward closing costs where the loan allows them.
• Look at a lower price range so the payment and cash to close both drop.
• Wait a few months and keep saving if your lease allows it.

Each choice has trade-offs. A lower payment with a healthy cushion often makes the first year calmer than a stretched purchase with no margin.

The bottom line

Reserves are what you have left after the closing costs are paid. Fannie Mae counts them in months of the new housing payment. Its automated system sets no fixed minimum for a typical one-unit primary home, but it can still ask for reserves. Whatever the lender requires, plan your own cushion around your total monthly spending.
