Definition
Proof of funds is documentation that shows a buyer genuinely has the money needed to close on your house. It's typically a recent bank statement, a brokerage statement, or a letter from whoever is holding the funds, dated within the last few weeks. Sellers ask for it to separate serious cash buyers from people who are just testing the market or don't actually have the money lined up. It plays the same role for a cash purchase that a mortgage pre-approval letter plays for a financed one — a quick way to gauge whether an offer is real before you take your home off the market.
Example
Before signing a purchase agreement, Angela asked her buyer for proof of funds and received a bank letter dated that week showing well more than the purchase price on deposit. It gave her the confidence to cancel her other showings and commit to that buyer's ten-day timeline instead of continuing to field offers from strangers online. Her agent double-checked the letter's date and the name on the account to make sure everything lined up with the buyer's stated identity, and even called the bank's listed number to confirm the letter was genuine. Angela also asked the buyer to route the sale through a licensed title company, which added another layer of protection before she took the house off the market. Two weeks later, the sale closed exactly as promised, funds arrived at the closing table, and the deed recorded without a hitch. Angela was glad she'd taken the extra few minutes to verify the paperwork up front rather than simply taking the buyer's word for it.
