A proof of funds letter is a document from your bank, credit union, or brokerage confirming that you hold enough liquid money to complete a specific purchase. Sellers in cash real estate deals, auction houses, and business sales ask for one before they’ll take an offer seriously. It does a single job: tells the other side you actually have the money, so no one negotiates a deal that can’t close.
It is not the same as a mortgage pre-approval. A pre-approval says a lender is willing to loan you money. A proof of funds letter says the money is already sitting in an account with your name on it. If a seller asks for one and you send the other, your offer can be rejected on the spot.
When You Actually Need One
Cash real estate purchases are the most common trigger. Without a mortgage lender independently verifying your finances, the seller has no other way to confirm you can pay. Several other situations call for one too:
- Real estate auctions. Most auction platforms and courthouse sales require proof of funds before you can register to bid, sometimes days ahead of the event.
- REO and bank-owned properties. Corporate sellers typically want proof of funds uploaded with the offer package before they’ll review it.
- HUD homes. Once a bid is accepted, you may have as little as two business days to submit a complete contract package including proof of funds.
- Competitive markets. Financed buyers sometimes include proof of their down payment funds to strengthen an offer against competing bids.
- Business acquisitions. Sellers want the same assurance before opening their books and sharing proprietary information.
The common thread: the party on the other side needs to know you’re not wasting their time. Earnest money alone doesn’t prove you can close, and losing one to three percent of the purchase price because you couldn’t fund the deal is an expensive lesson.
What Belongs in the Letter
The format is predictable, and missing any element gives the recipient a reason to reject it.
- Bank letterhead with the institution’s official name, address, phone number, and email. Letters not on official letterhead are frequently rejected.
- The date the letter was issued. This matters more than people realize, because the document has a short shelf life.
- Your full legal name, exactly as it appears on the purchase contract. A mismatch creates problems.
- Account type and account number. Many banks partially redact the number for security and show only the last four digits.
- The available balance as of the date on the letter. Some letters confirm “at least” a stated amount rather than disclosing the full balance, which protects your negotiating position.
- A statement that the funds are liquid and not subject to holds, restrictions, or penalties.
- An authorized bank officer’s signature with printed name, title, and direct contact information so the recipient can verify by phone.
The verification contact is the piece most people overlook. A letter the seller can’t verify is barely better than no letter at all. Ask for a direct line to the signing officer, not just the bank’s general customer service number.
What Counts as Liquid Funds
The money referenced in the letter has to be cash you can actually access quickly. Standard checking and savings balances are the easiest to document and the most universally accepted. Money market accounts and open lines of credit with available balances also qualify in many transactions.
What usually doesn’t qualify: retirement accounts with early withdrawal penalties, whole life insurance cash values, unliquidated stock portfolios, bonds, mutual funds, and real estate equity. These hold value, but they can’t be wired to a title company next week, which is the whole point. If your wealth sits in non-liquid assets, plan to liquidate first and request the letter once the cash has settled in a bank account.
Cryptocurrency is a newer complication. Most traditional sellers and title companies won’t accept a screenshot of a crypto wallet. The safest path is converting to cash in a bank account before requesting your letter.
How to Request One
Start with the institution where the funds are held. Most banks can generate the letter within one to three business days, and many larger banks let you request one through your online banking portal. Smaller institutions or requests needing customized language are faster handled by visiting a branch. Some banks provide the letter free as a routine account service; others charge a small processing fee.
Online brokerages including Fidelity, Schwab, and Vanguard can also issue proof of funds letters confirming your account balances. One advantage: some platforms let you generate a letter for a specific dollar amount rather than revealing your total holdings, which keeps your full financial picture private.
When you make the request, tell the bank exactly what the letter is for, the dollar amount you need confirmed, and who will receive it. If you know the property address, include it. A specific request reduces the chance you’ll need a revision that costs you another day or two.
Hard Money and Private Lenders
Real estate investors working with hard money lenders have a different path. Many private lenders issue proof of funds letters confirming that financing has been allocated for a specific deal, sometimes within 30 minutes during business hours. Some charge a one-time processing fee of a few hundred dollars for borrowers without an active loan, occasionally credited back at closing if you fund through the same lender.
The important difference: a hard money letter confirms lending capacity, not cash in a bank account. Some sellers, particularly in competitive residential markets, prefer to see actual bank balances. Know your audience before choosing this route.
Bank Statements as an Alternative
Not every transaction demands a formal letter. Some sellers and agents accept recent bank statements, provided they’re official, show the account holder’s name, and display a sufficient balance. Brokerage statements sometimes work too.
The downside is privacy. A full statement shows every deposit, withdrawal, and transaction for the period. A formal letter discloses only what the recipient needs: your name, your institution, and the fact that you have enough money. That targeted disclosure is reason enough to request the letter whenever you can.
How Long the Letter Stays Valid
The document has a short shelf life. Most sellers and their agents want documentation dated within 30 to 60 days of the offer. Beyond that, account balances may have shifted enough to make the letter unreliable.
Some contexts are stricter. Commercial real estate auction platforms may accept documentation up to 90 days old, while certain corporate sellers of bank-owned properties want letters less than seven days old. If your home search stretches longer than expected, plan to request refreshed letters rather than reusing one from weeks ago. Timing the request so the letter is as fresh as possible when you submit gives you the strongest position.
Protecting Your Financial Privacy
The letter contains sensitive information, and once you hand it to a seller’s agent you’ve lost control of where the document travels. A few steps reduce your exposure.
Ask the bank to confirm only the minimum amount needed rather than your full account balance. If you have $800,000 in the bank and you’re making a $400,000 offer, a letter confirming “at least $400,000” serves the same purpose without giving the seller leverage to push for a higher price. Revealing total wealth invites tougher negotiations.
If you submit bank statements instead of a formal letter, redact anything the recipient doesn’t need: individual transaction descriptions, routing numbers, and most of the account number. Leaving the last four digits visible is standard. Keep the bank name, your name, statement dates, and balances visible, since those are the elements the recipient needs to verify. Redacting is legal and expected as long as you don’t alter dollar amounts or fabricate information.
Share the letter only with verified parties: your agent, the seller’s agent, the title company, or the lender. Avoid unencrypted email where you can. Many real estate professionals use secure transaction management platforms with encrypted, access-controlled document uploads. After closing, destroy extra copies containing full account numbers and keep one secured copy for your records.
The Legal Risk of Faking One
Fabricating or altering a proof of funds letter is not a minor infraction. If the letter is used to influence a transaction involving a federally related mortgage loan, a bank, or any federally insured institution, federal law makes it a serious crime. Under 18 U.S.C. ยง 1014, knowingly making a false statement to influence the action of a financial institution in connection with a loan, purchase agreement, or related transaction carries a potential fine of up to $1,000,000 and up to 30 years in prison.1Office of the Law Revision Counsel. 18 U.S.C. 1014 – Loan and Credit Applications Generally
Even outside the federal context, submitting a fraudulent financial document exposes you to state fraud charges and civil suits from anyone who relied on the document. A seller who accepted your offer and took their home off the market can sue for their losses. You’d also forfeit any earnest money, which on a $400,000 home could mean $4,000 to $12,000 gone immediately.2My Home by Freddie Mac. What Is Earnest Money and How Does It Work?
The verification path on a legitimate letter exists because sellers do call to check. A bank officer who never signed the letter, or an institution with no record of you as a client, ends the deal and starts a paper trail that can follow you into criminal proceedings.
