Proof of funds is a document, usually a bank or brokerage statement, that shows you have the cash available to close on a home. Sellers typically ask for it on all-cash offers, in competitive bidding situations, or on short sales, while financed buyers are more often asked for a preapproval letter instead. Both the Consumer Financial Protection Bureau and Fannie Mae set the standards most lenders and agents follow.

TL;DR:

• Requirements vary by seller, listing agent, and local custom; earnest money shows commitment but does not prove you can fund the remaining purchase price.
• Use a recent bank or brokerage statement, signed bank letter, or asset verification report, and redact full account numbers, routing numbers, and unrelated transactions.
• Gifted funds need a signed letter and transfer evidence, while home sale proceeds require a settlement statement showing net cash, not merely a listing agreement.
• A seller’s snapshot may not satisfy underwriting; lenders may request two consecutive monthly statements and written explanations for large recent deposits, so retain transfer records.

What proof of funds is and how it differs from a lender preapproval

Proof of funds is evidence that money for a purchase actually exists and is accessible to you right now. A bank statement, brokerage statement, or dated bank letter all serve this purpose because they show a real balance tied to your name on a specific date.

A preapproval letter is something different. It states a lender’s tentative willingness to extend financing up to a certain amount, but it is not a guaranteed loan and it commonly expires within 30 to 60 days. A seller reading a preapproval letter learns the buyer is likely to qualify for a mortgage. A seller reading proof of funds learns the buyer already has the cash.

• Proof of funds answers “do you have the money.”
• Preapproval answers “will a lender probably give you the money.”
• Sellers choose which one they want based on how the offer is structured.

Since terminology gets used loosely in practice, it helps to ask the listing agent directly whether they want funds verified or a lender’s preapproval, since the two documents prove very different things.

When sellers or listing agents will ask for proof of funds

Cash offers almost always trigger a proof of funds request because there is no lender in the deal to vouch for the buyer’s ability to pay. Listing agents want assurance the money is real before taking a property off the market.

Competitive, multiple-offer situations are the second common trigger. When several buyers compete for one house, agents often ask every cash buyer, and sometimes every buyer, to attach proof of funds to strengthen the offer. Short sales add another layer: because the lender holding the mortgage has to approve the sale price, listing instructions in a short sale workflow frequently specify exact documentation buyers must submit upfront.

• All-cash purchases, where no mortgage lender is involved.
• Multiple-offer scenarios where sellers want to rank serious buyers.
• Short sales, where the seller’s lender dictates documentation rules.

None of this is standardized. The exact requirement comes from the seller, the listing agent, and local custom, not a universal form. It is also worth separating proof of funds from earnest money, which is a deposit held in escrow after an offer is accepted. Earnest money shows commitment to a specific deal; it does not prove you can fund the rest of the purchase, so sellers sometimes want both.

Documents that qualify as proof of funds

Lenders and listing agents generally accept the same core set of records, following Fannie Mae’s verification standards for what counts as credible evidence.

1. Bank or brokerage statements showing the institution name, your name as account holder, the statement period, the ending balance, and only the last four digits of the account number.
2. A bank-issued verification-of-deposit letter, sometimes formatted as Fannie Mae’s Form 1006, which a bank officer signs to confirm your balance directly to the requester.
3. Third-party asset-verification reports, generated through automated services lenders use when they want faster, standardized confirmation instead of manual statements.
4. Settlement statements or gift documentation when the funds come from selling another property or from a family member rather than from savings alone.

Pro Tip: Redact everything except what’s needed to identify the account. Full account numbers, routing numbers, and unrelated transaction history only create unnecessary exposure.

Retirement account statements can work too, but sellers and lenders usually want a cover note explaining the type of account and any penalty or tax consequence tied to withdrawing early. Sale proceeds and gifted money come with their own documentation rules, covered in the special cases section below.

How to get a seller-facing proof of funds letter quickly

Getting a usable letter together doesn’t have to take long if you know which option fits your situation.

1. Request a dated bank letter. Call or visit your bank and ask for a letter on official letterhead naming the account holder, the institution, the current balance, and a contact number the recipient can call to verify it.
2. Order a third-party asset-verification report. If your lender already uses an automated validation service, you can consent to electronic account retrieval, which produces a standardized report faster than a manual bank visit.
3. Have your agent submit current statements with a short cover note. Many sellers accept recent statements plus a brief explanation and bank contact information instead of a formal letter, especially outside short sales.

Pro Tip: Pull your statement within a few days of making an offer. An older balance may invite questions, and some agents will ask you to refresh it before they’ll present your offer.

Document any large transfer into the account before you request the letter, since a sudden deposit without explanation is one of the fastest ways to stall a request. Ask upfront how long the seller or agent will consider the document current. A loan application packet later in the process will require far more detail than this initial letter, so treat the proof of funds letter as a snapshot, not a substitute for underwriting.

Special cases: crypto, gifted funds, sale proceeds, and timing

A few situations need extra documentation because they introduce questions about liquidity or source.

• Cryptocurrency worries sellers and title companies because its value swings and it isn’t immediately spendable like cash. Converting to dollars before making an offer and keeping transfer and tax records, as outlined in NAR’s crypto transaction guidance, removes most of that friction.
• Gifted funds typically require a signed gift letter stating the money doesn’t need repayment, plus evidence of the actual transfer into your account.
• Proceeds from selling another home need a settlement statement showing the real net proceeds. A listing agreement or signed contract alone does not count as proof those funds exist.
• Timing and liquidity matter as much as the total balance: sellers want funds that are accessible on the closing date, not tied up in a sale or transfer that hasn’t settled yet.

What happens after you submit proof of funds

A seller-facing proof of funds letter gets your offer accepted, but it is not the end of financial scrutiny. Once a lender is involved, underwriting kicks in and typically asks for updated statements, written explanations for any large recent deposits, and documentation tying every dollar to its source.

• Expect a request for fresh statements closer to your closing date.
• Be ready to explain any deposit that doesn’t match your regular income pattern.
• Lenders using automated asset-validation tools may request two consecutive months of statements or a formal verification-of-deposit form rather than accept a single snapshot.

One detail buyers often miss: according to Fannie Mae’s underwriting requirements, the system frequently calls for two consecutive monthly statements, not one, so a single current balance that satisfied a seller may not satisfy the lender later. Keep records of every transfer and confirm wiring instructions directly with your title company, since those instructions get targeted by fraud and should never be trusted from an unverified email alone, a point reinforced in the CFPB’s closing guidance.

What experienced deal advisors want buyers to know

After years of preparing deals on the business side, one pattern holds for home purchases too: sellers reward buyers who make verification effortless. A messy, outdated, or confusing proof of funds packet signals risk even when the money is perfectly real.

Before you make an offer, assemble recent bank statements, a bank-issued proof of funds letter, a signed gift letter if any funds were gifted, a settlement statement if you’re using sale proceeds, and the direct contact information for whoever at the bank can confirm the letter, referring to the commercial inspection checklist to coordinate timelines effectively. Give copies to your agent, your lender, and the title company at the same time, and ask each one which format they actually want. A little redundancy here avoids a scramble during a tight closing window.

Documenting your finances well pays off beyond home buying

The same discipline that makes a home purchase go smoothly, clean records, verifiable balances, and documentation a third party can trust on sight, is exactly what makes a business sale or acquisition move faster too. We built our process around that principle: at Captyx, we prepare sellers and buyers with financial documentation for business transactions.

If you’re on the buying side of a business acquisition rather than a home, our buy-side advisory work can help you consider proof of capital, deal structure, and feedback from the other side of the table before you make an offer. And if you’re a business owner thinking about your own exit down the line, our free valuation gives you a starting number backed by our experience. Reach out when you’re ready to see what either side of that process looks like for you.

FAQ

How do you do proof of funds?

You request a current bank or brokerage statement, or a signed letter from your bank, showing your name, the account balance, and the statement date. Submit it to your agent or directly to the listing agent along with any cover note the seller’s instructions require.

What is a POF?

A POF, or proof of funds, is a document confirming that a buyer has enough liquid money available to complete a purchase. It is commonly a bank statement, brokerage statement, or bank-issued letter, and it is distinct from a mortgage preapproval letter, which reflects a lender’s tentative willingness to finance rather than existing cash.

Can I use my 401k as proof of funds?

A retirement account statement can serve as proof of funds, but sellers and lenders usually want clarification on whether you plan to withdraw the money and what penalties or taxes that triggers. It helps to pair the statement with a short note explaining your plan for accessing those funds before closing.

What documents can I use as proof of funds for a property purchase?

Acceptable documents include recent bank or brokerage statements, a bank-issued verification-of-deposit letter, or a third-party asset-verification report. If the funds come from selling another home, a settlement statement showing actual net proceeds is required rather than a listing agreement.

Do I need both earnest money and proof of funds?

Yes, sellers often ask for both because they prove different things. Earnest money is a deposit held in escrow that shows commitment to a specific offer, while proof of funds shows you can cover the full purchase price.
