A proof of funds letter to buy a house with cash is a current bank document, in your name, showing liquid money equal to or greater than the purchase price. Sellers ask for it because accepting your offer takes their property off the market, and they want evidence the money is real before they commit. In most transactions, a recent bank statement or a short letter from your bank is all you need, delivered to the listing agent at the same time as your signed offer.
Which Accounts Actually Count
The cleanest proof comes from accounts where the money is already cash: checking, savings, and money market accounts. The balance shown is the balance available. No conversion, no waiting, no market risk. A recent monthly statement or a formal letter covering one of these accounts is what most listing agents expect.
Brokerage accounts holding stocks, bonds, or mutual funds can work, but they raise questions. A seller may wonder whether the investments can be sold fast enough and whether the proceeds will match the stated value after the market moves. Securities held with a broker-dealer now settle on a T+1 basis, meaning one business day after the sale, under SEC Rule 15c6-1 as amended in 2024.1U.S. Securities and Exchange Commission. Shortening the Securities Transaction Settlement Cycle That is fast, but it still means the money is not truly liquid on the day the statement prints. If you plan to use brokerage assets, include a brief note alongside the statement explaining the settlement timeline.
What Doesn’t Qualify
Equity in another property is not proof of funds. You cannot spend home equity at a closing table without first selling or borrowing against the property, which is exactly the delay the seller is trying to avoid. Retirement accounts have a similar problem. Withdrawals before age 59½ trigger a 10% early distribution tax on top of regular income tax, so the balance on the statement overstates what you would actually net.2Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Most sellers and agents will refuse these accounts.
Gift Funds
If a family member is contributing part or all of the purchase money, a bank statement alone is not enough. The standard practice is a signed gift letter from the donor stating the dollar amount, confirming no repayment is expected, and identifying the donor’s relationship to you. Be ready to show a paper trail of the transfer, like a copy of the donor’s check or a record of the electronic transfer. This protects both sides by making clear the money is a gift, not a disguised loan.
Gifts above $19,000 per recipient in 2026 require the donor to file a gift tax return, though no tax is typically owed unless the donor has used up the lifetime exemption.3Internal Revenue Service. What’s New – Estate and Gift Tax The filing falls on the donor, but mention it so they are not surprised at tax time.
What the Letter Has to Show
The document has to tie the money to you specifically. The full legal name on the account must match the name on the purchase contract. If your bank account reads “Robert J. Smith” and your offer reads “Bob Smith,” some listing agents will ask for additional identification. The financial institution’s name and logo should be clearly visible so the seller’s side can confirm the source is a real, regulated bank.
The balance must equal or exceed the purchase price. If you are offering $450,000, the document needs to reflect at least that amount in available funds. In practice, show a buffer above the price, because closing costs sit on top of the offer. The document also needs to be current. Most agents want proof dated within 30 days of the offer. An older statement raises the obvious concern that you may have spent the money since it was generated. Pull a fresh copy before each new offer if your shopping is dragging on.
Bank Statement or Formal Bank Letter
You have two ways to produce proof of funds. The first is a downloaded PDF of your most recent account statement. Log into your online banking portal, open the statement or balance summary, and save it. Fast and free, and acceptable in most transactions.
The second is a letter on bank letterhead, signed by a branch officer, confirming that you hold sufficient funds for a real estate purchase. This carries slightly more weight because it is a direct assertion from the bank rather than a snapshot of activity. The letter should include the officer’s name, title, and direct phone number so the listing agent can call to verify it. Some banks produce these same day; others take two or three business days. Request it before you start making offers, not after you find the house.
Redact Before You Send
Your statement contains details no listing agent needs: the full account number, any reference to your Social Security number, and every transaction line. Before sharing, use a digital redaction tool or a black marker on a printed copy to block out anything not relevant to proving you have the money. Keep the account holder’s name, the institution’s name and logo, the total balance, and the statement date fully visible. If the document uses a partial account number for identification, leave the last four digits intact.
There is a balance to strike. Over-redacting, where the document is more blacked out than readable, looks tampered with and can kill an otherwise strong offer. The goal is to protect your identity without making the agent suspicious. A formal bank letter typically contains only the relevant details, so little or no redaction is needed.
Submitting It With Your Offer
The redacted document goes to the listing agent at the same time as your purchase offer. Attach the PDF to the email containing your signed contract, or upload it to whichever secure transaction platform the agents are using. Sending it simultaneously signals that you are serious and prepared, which matters in a competitive market where sellers compare offers side by side.
The listing agent may call your bank to confirm the letter is genuine and the balance is accurate. This is a limited check, not a deep dive into your finances. Once the seller accepts your offer with the proof of funds attached, the transaction moves into title search, inspection, and escrow without the weeks of lender underwriting.
Build a Buffer for Closing Costs
A cash purchase skips lender fees, appraisal requirements, and mortgage insurance, but real costs still remain. Underestimating them is one of the most common mistakes cash buyers make, and it can stall a deal at the worst moment.
You will owe some combination of the following at closing:
- Title search and an owner’s title insurance policy, typically $1,000 to $4,000 depending on the property’s value and location.
- Escrow or settlement fees for the company or attorney coordinating the closing, usually $500 to $2,000.
- Recording fees paid to the county recorder, often under $200 but non-negotiable.
- Transfer taxes, which vary from zero in states that do not levy them to as high as 2% or 3% of the sale price in some high-cost states.
- A prorated share of property taxes, plus a homeowner’s insurance policy in place before the deed transfers. Without a lender escrowing these, you handle them directly.
Expect roughly 1% to 3% of the purchase price in closing costs. On a $450,000 home, that is $4,500 to $13,500 beyond the offer itself. Your proof of funds should reflect that cushion so the seller does not have to ask whether you can cover the full transaction.
If You’re Liquidating Investments, Check the Tax Math First
Selling stocks or funds to generate the cash means the proceeds will be smaller than the balance on your brokerage statement. Long-term capital gains (on assets held more than a year) are taxed at 0%, 15%, or 20% in 2026 depending on income; short-term gains are taxed as ordinary income, which can run as high as 37% in 2026.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill High earners also face a 3.8% Net Investment Income Tax above $200,000 of modified AGI for single filers or $250,000 for joint filers, a threshold a large sale can push you across even if your salary would not.5Internal Revenue Service.

Protect the Wire
The FBI’s Internet Crime Complaint Center reported over $173 million in real estate wire fraud losses in 2024 across more than 9,300 complaints.7FBI Internet Crime Complaint Center. 2024 IC3 Annual Report The scheme is simple: a criminal compromises an email account belonging to your agent, title company, or closing attorney and sends wiring instructions that look legitimate but route the money to the criminal’s account. Once the wire goes through, recovery is rare. Cash buyers are prime targets because the full purchase price moves in a single transfer with no lender fraud controls in the loop.
Three precautions handle most of the risk:
- Get wiring instructions in person at the title company’s office, or by phone at a number you looked up independently (not one in an email). Verify every detail verbally before sending.
- Treat last-minute changes to wiring instructions as a red flag. Title companies do not randomly switch bank accounts. Confirm through a known contact before you act.
- Call the title company right after you send to confirm receipt. Do not wait for them to contact you.
The urgency of a closing is what scammers rely on. One phone call to a verified number is the single most effective thing you can do to protect the money.
A Note on Federal Reporting
Two reporting rules can surface in a cash purchase, and knowing they exist keeps you from being caught off guard. Neither creates a tax liability on its own.
Businesses receiving more than $10,000 in “cash” in a single transaction must file IRS Form 8300 within 15 days.8Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 “Cash” here has a specific meaning: currency, cashier’s checks, money orders, and bank drafts of $10,000 or less, but not personal checks or wire transfers.9Internal Revenue Service. IRS Form 8300 Reference Guide Since most “cash” home purchases are actually wires, Form 8300 is less commonly triggered than people assume. Deliberately structuring payments to stay under the threshold is itself a federal offense.
Starting March 1, 2026, FinCEN’s Residential Real Estate Rule requires certain professionals at closing to report non-financed residential transfers when the buyer is a legal entity or trust.10Financial Crimes Enforcement Network. Residential Real Estate Rule If you are buying through an LLC, corporation, partnership, or trust, the title company will need to identify and report the beneficial owners. Buyers purchasing in their own name are not directly affected, but anyone using an entity for privacy or liability protection should expect extra documentation at closing.
