A proof of funds letter is a document from your bank or brokerage that confirms you have a specific amount of money available and ready to use for a transaction. Sellers ask for it before they’ll take an offer seriously, most commonly in real estate but also in business acquisitions, immigration filings, and some large equipment purchases. You get one by asking your financial institution to prepare it, usually within a business day or two.
What the Document Actually Shows
Two formats are widely accepted. The simpler one is a recent bank statement showing your checking or savings balance, with your name as account holder clearly displayed. A brokerage statement works too, provided the holdings are liquid — cash or securities you could sell quickly.
The stronger version is a certified letter from your bank, sometimes called a proof of funds letter. A bank officer writes and signs it, stating that a specific dollar amount is on deposit in your account as of a specific date. Because it comes directly from the institution rather than a PDF you printed, many sellers and their agents prefer it.
A line of credit is sometimes offered as supplementary proof, but expect resistance. It represents borrowing capacity, not money you actually hold, and the other party will want confirmation you can draw on it immediately. In competitive situations, deposited funds are what carries weight.
What Doesn’t Count
Money locked in retirement accounts like 401(k)s or IRAs won’t satisfy a proof of funds request. Neither will illiquid holdings such as private equity stakes, real estate equity, or collectibles. The point of the document is to show cash you can deploy now, not net worth tied up in assets that would take weeks or months to convert.
Cryptocurrency remains a gray area. Most sellers and listing agents won’t accept a wallet screenshot or exchange balance, because neither reliably proves you can withdraw and wire the money at closing. The practical route is to convert crypto to cash first, then submit a traditional bank statement showing the converted funds.
Proof of Funds vs. Pre-Approval Letter
These get mixed up constantly, and submitting the wrong one at the wrong moment can sink an offer. They do different jobs.
A proof of funds letter shows you have cash on hand for the down payment and closing costs. A pre-approval letter (or prequalification letter) shows that a lender has reviewed your finances and is willing to extend a mortgage for a specific amount. If you’re paying cash, you only need proof of funds. If you’re financing, you typically need both: the pre-approval demonstrates you can get the loan, and the proof of funds demonstrates you can cover the out-of-pocket costs the loan won’t.
Handing a seller a pre-approval letter when they asked for proof of funds signals that you don’t understand the process. In a market with multiple bidders, that alone can drop your offer out of contention.
When You’ll Be Asked for One
Real Estate
This is where most people first run into the requirement. On an all-cash offer, the listing agent will almost certainly want a proof of funds letter attached to the bid, and offers without one tend to get set aside. Even with a mortgage, you may still need to document your down payment and closing funds. Lenders often verify this through bank statements or a formal Verification of Deposit (Fannie Mae Form 1006), which the lender sends directly to your bank. For purchase transactions, the documentation must cover the most recent 60 days of account activity.1Fannie Mae. Verification of Deposits and Assets
Business Acquisitions
A seller isn’t going to open the company’s books to a prospective buyer who hasn’t shown the money exists. Buyers are usually asked to prove they have both the purchase price and enough working capital to keep the business running after closing. In larger deals, buyers sometimes deposit funds into escrow and use documentation of that account as their proof.
Immigration and Visa Applications
Several immigration pathways require you to show you can support yourself or make a qualifying investment. Under federal immigration law, officers evaluate whether an applicant is likely to become a “public charge” by weighing assets, resources, and financial status among other factors.2Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens Investor visa programs like EB-5 go further, requiring documentation that the invested capital was obtained lawfully, with tax returns and business records going back years.3U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 6 Part G Chapter 2 – Immigrant Petition Eligibility Requirements
Large Equipment and Industrial Purchases
Vendors handling high-value or custom-built equipment sometimes ask for proof of funds before starting production. When a build ties up capacity for weeks, the seller wants confirmation the buyer can pay. Formats here are less standardized than in real estate; the vendor tells you what they’ll accept.
What Makes the Document Valid
Not every statement you can print will hold up. A usable proof of funds document meets a few standards.
- Recency. The document should reflect your current position. Fannie Mae requires statements covering the most recent 60 days, and if the latest statement is more than 45 days old at loan application, the lender will ask for a supplemental update. Outside mortgage contexts, most parties expect documentation dated within 30 to 60 days.1Fannie Mae. Verification of Deposits and Assets
- Name match. The name on the document must match the name on your offer or application exactly. If funds sit in a trust, an LLC, or someone else’s account, you’ll need a separate legal document, such as a power of attorney or corporate resolution, authorizing you to use them.
- Liquidity. The balance shown must be immediately accessible. A brokerage statement listing $500,000 means little if most of that is in restricted stock or subject to a lockup.
- Official formatting. A certified bank letter should be on bank letterhead and include the officer’s signature and direct contact information so the recipient can verify it independently.
How to Request the Letter From Your Bank
Contact your bank or brokerage first. Most institutions can produce a basic proof of funds letter within one to two business days, and many don’t charge for it. Some charge a small administrative fee for expedited turnaround. If you bank online without a local branch, check whether the letter can be requested through the online portal or customer service line.
When you make the request, specify what the letter needs to include: the exact dollar amount to be verified, the date the balance should be confirmed as of, and whether it should reference a specific transaction or recipient. Precision on the front end reduces the chance of a revision that eats into your offer deadline.
Before submitting the letter, check it. Confirm the account holder’s name matches your offer documents, the balance shown is sufficient, and the bank officer’s contact information is included so the recipient can verify it. Request the letter well ahead of any deadline; waiting until the last day leaves no room if internal compliance review slows things down.
Protecting Your Financial Information
The document holds sensitive data, and you should handle it that way. Before sending, redact your full account number; the last four digits are enough for most verification purposes. Redact routing numbers, card numbers, and transaction details that aren’t relevant to the balance being confirmed.
Send the document through secure channels: an encrypted email, a secure portal provided by the title company or agent, or in person. Avoid unencrypted email for financial documents. One specific caution for mortgage transactions: if anyone asks you to hand-carry a Verification of Deposit form to your bank yourself, that’s a red flag. Fannie Mae requires those forms to move directly between lender and bank, never through the borrower.1Fannie Mae. Verification of Deposits and Assets
Foreign Bank Accounts and Translation
You can use funds held outside the United States, but the document has to be readable and trusted by the recipient. For immigration filings, USCIS requires foreign-language documents to be accompanied by a full English translation and a signed certification from the translator stating the translation is complete and accurate and that the translator is competent in both languages. The certification must include the translator’s name, signature, address, and date.4U.S. Department of State Archive. Information about Translating Foreign Documents Notarization isn’t strictly required, but it’s common.
Real estate transactions don’t impose the same formal rules, but the practical hurdle is identical: the seller or their agent has to read and trust what you send. A professional certified translation removes the doubt. If you’re pulling documents from a foreign bank, build in extra time for the statement itself and the translation, particularly across time zones.
