Can You Use Personal Checks for Mortgage and Closing Costs?
By Michael George, NMLS #2280851 · October 17, 2026
Plenty of people write exactly one check a month: the rent. If that’s you, the tool up top already saves you a trip to the bank. A home purchase runs on checks too, and each one has its own rules. Here’s the tour, from the first check of the deal to the ones that show up after you get the keys.
Earnest money: the first check of homeownership
In Arizona, the first real money moves when your offer gets accepted. That payment is the earnest money deposit: a good-faith sum that tells the seller you mean it. It’s commonly a personal check. It never goes to the seller; it goes to a neutral third party called escrow — usually the title company running your closing — and waits there until closing day, when it’s credited toward your down payment and closing costs. Whether it comes back if the deal falls through depends on your contract, which the National Association of REALTORS explains in its plain-English guide to escrow and earnest money.
The down payment: where a personal check runs out of road
For most things, a personal check is fine. A down payment is the exception. It’s often the biggest check of your life, and the company running your closing can’t pay anyone with money that isn’t there yet.
Arizona has a good-funds law for exactly this reason. An escrow company may only disburse against money that has actually cleared: wires, cashier’s checks, and similar. You can legally hand escrow a personal check, but they can’t pay out against it until the deposit clears, and federal funds-availability rules let banks place week-plus holds on very large check deposits. That’s why the standard move is a wire transfer or a cashier’s check, arranged a few days before closing. Each title company sets its own deadline, so ask your escrow officer how early your money needs to land, and mind your bank’s daily wire cut-off. Our closing costs guide and down payment guide have the full picture.
When family helps: the gift check
A lot of down payments start at a family dinner table. Mom and Dad write a check, you deposit it, done. A mortgage lender needs more than the check, though: a signed gift letter saying the money is a true gift with no repayment expected, plus a paper trail — a copy of the check, your deposit slip, and the bank statement showing it landed. Two timing notes: deposit the check early so the trail is complete before underwriting looks, and if gift money is still coming at closing itself, the donor should wire it or send a cashier’s check, because that’s what closing agents accept at the table.
The checks that come after closing
Homeownership has its own check economy:
A voided check for your mortgage payment. Most servicers set up automatic monthly payments as an ACH transfer (an automatic bank-to-bank payment), and many ask for a voided check so your routing and account numbers get copied exactly. Print one with the tool above and write VOID across the front. Our mortgage process guide covers the after-closing handoff.
The escrow refund check. Your servicer collects taxes and insurance with each payment and holds the money in an escrow account, then runs the numbers once a year. Collected too much? If the surplus is $50 or more and you’re current on the loan, federal rules require a refund within 30 days, often as a check in the mailbox.
A checkbook from your equity. If you ever borrow against your home with a HELOC, don’t be surprised when the bank hands you special checks for drawing on your line. The check writer above works for those too.
And when you’re ready to stop writing rent checks for good, that’s our day job. Mortgage Genius helps Arizona buyers and homeowners with every loan in the menu above. Run the numbers on our calculators, or call (480) 613-8040 and ask anything — the call is free too.
Checks and closings: common questions
Can I pay my down payment with a personal check?
Almost never at the closing table. Arizona’s good-funds law (A.R.S. § 6-843) lets an escrow company pay out only against money that has cleared, like a wire or a cashier’s check. A personal check can be deposited, but escrow can’t disburse against it until the deposit clears, and very large checks can be held for a week or more. Plan on a wire or a cashier’s check, and ask your escrow officer how early the money is due. The Consumer Financial Protection Bureau says it plainly: cash to close is usually made by cashier’s check or wire transfer.
What’s the difference between a personal check, a certified check, and a cashier’s check?
A personal check pays from your account whenever the recipient deposits it, with nothing standing behind it but your balance. A certified check is your check with the bank verifying the money is there and setting it aside. A cashier’s check is the bank’s own check: you hand the bank the money first, and the bank owes the payee. That guarantee is why closings run on cashier’s checks or wires. The CFPB’s home-buying guide walks through how cash to close gets paid.
My family is giving us money for the down payment. Can they just write a check?
Usually yes, with paperwork. Fannie Mae’s gift rules call for a signed gift letter from the donor, stating the amount and that no repayment is expected, plus evidence of the transfer such as a copy of the donor’s check and your deposit slip. Deposit the check early so the paper trail is complete before closing. Fannie Mae also sets a timing rule: gift money delivered at the closing itself must arrive by electronic transfer, certified check, or cashier’s check.
Why does my mortgage company want a voided check?
So your routing and account numbers get copied exactly, with no typos, when they set up automatic payments. Many servicers ask for a voided check or a deposit slip on their automatic-payment enrollment forms; plenty also let you enroll online instead. Need one today? Print a check with the tool above and write VOID across the front in big letters.
Is a check or a wire safer for closing money?
They fail in different ways. A check that gets lost or stolen can usually be stopped before it’s cashed. A wire that lands in a thief’s account is usually gone, which is exactly why scammers target closings: they hack an email thread and send fake wiring instructions days before you close. The CFPB’s advice is to confirm wiring instructions by phone, using a number you looked up yourself, never one printed in the email. If the wiring details change late in the deal, stop and call your escrow officer.
