A proof of funds letter is a document, usually from a bank, brokerage or lender, showing that a buyer has the cash or committed financing to close a purchase. For a wholesaler, it is the piece of paper a seller, listing agent or bank asks for before taking your offer seriously, and the honest way to provide one depends on where the closing money is really coming from. Offers on bank-owned REO listings, for example, usually need proof of funds attached before the asset manager will review them.
Most pages on this topic either sell a “free POF letter” or treat the letter as a formality. It isn’t. It is a statement of fact about money, and the way you get one, describe it and use it decides whether it helps you win contracts or creates legal exposure. This guide covers what the letter contains, who asks for it, where a wholesaler’s funds actually come from, a worked example, and where people get it wrong.
Why cash offers still get asked for proof
Cash buyers remain a large share of the market, which is exactly why sellers and agents screen them. In NAR’s August 2026 existing-home sales report, 27% of transactions were all-cash, and individual investors or second-home buyers made up 15% of sales. Every one of those cash offers competes with financed offers that come with a lender’s pre-approval. A cash offer without evidence of cash looks weaker than a financed offer with it.
Off-market sellers are often less formal than listing agents, but the closer you get to a listed property, a bank-owned home or an estate represented by an attorney, the more likely you are to hear “send proof of funds with the offer.”
What goes into a proof of funds letter
There is no single legal form. What sellers and agents expect to see is fairly consistent:
- The issuer’s letterhead and contact details, so the reader can call and verify it independently.
- The account holder’s legal name, which should match the buyer named on the purchase agreement, or a company you clearly control.
- The amount available, either a balance or a statement that funds of at least a stated amount are available.
- A recent date. Many agents won’t accept anything more than about 30 days old, and some want it dated within the week of the offer.
- A signature from a bank officer, or for a lender, the person authorized to issue commitments.
Account numbers should be masked. A seller needs to know the money exists, not how to reach it. If you send a statement instead of a letter, black out everything but the institution, your name, the date and the balance.
Who asks, and what they will accept
| Who asks | When | What usually satisfies them |
|---|---|---|
| Off-market seller | Rarely, or after you sign | A conversation, a title company name, and a realistic closing date |
| Listing agent | With the offer | Bank letter or masked statement dated within the last few weeks |
| Bank-owned (REO) asset manager | With the offer, often through a portal | Bank letter in the buyer entity’s name, sometimes a lender commitment |
| Probate attorney or personal representative | Before acceptance | Bank letter plus the name of the closing attorney or title company |
| Auction platform | Before you can bid | Platform-specific verification, often a deposit |
The pattern is simple: the more professional the person on the other side, the more likely they are to call the bank or lender listed on the letter. Assume every letter will be verified.
Proof of funds vs. pre-approval vs. a bank statement
These get used interchangeably, and they shouldn’t be. The CFPB notes that a prequalification or pre-approval letter says a lender is generally willing to lend up to an amount based on certain assumptions, and is not a guaranteed loan offer. Proof of funds says the money is already there.
| Document | What it proves | Best use | Weak point |
|---|---|---|---|
| Bank POF letter | Cash on deposit as of a date | Cash offers on listed or REO property | Only as strong as the balance behind it |
| Masked bank or brokerage statement | Balance as of statement date | Quick offers where the agent accepts statements | Goes stale fast; easy to question |
| Hard money or private lender commitment | A lender has reviewed you and the deal | Financed “cash” purchases that close fast | Conditional on appraisal, title and terms |
| Mortgage pre-approval | A lender will likely lend to you | Owner-occupant purchases | Not proof of cash, and usually not for investor flips |
| Transactional funding letter | A funder will fund a double close if conditions are met | The A-to-B leg of a double close | Depends on a confirmed end buyer |
Where a wholesaler’s money actually comes from
This is the part most guides skip. A wholesaler usually isn’t the one who will pay the seller. So before you hand anyone a proof of funds letter, answer a plain question: whose money closes this deal?
Your own cash
If you have the purchase price in an account, a letter from your bank is the cleanest answer. It is also the least common situation for a new wholesaler, and it carries a quiet obligation: if your end buyer walks, a seller who saw your balance may reasonably expect you to close.
Transactional funding for a double close
If you plan to double close with transactional funding, the funder is the source of the A-to-B money. Many funders will issue a letter describing what they will fund and on what conditions, usually a signed contract with your end buyer and the buyer’s funds in escrow. That letter is accurate as long as you describe it accurately: funding is committed for a double close, not sitting in your account.
Your end buyer’s funds on an assignment
On an assignment, the end buyer pays the seller at closing. Their proof of funds is the real proof for the deal. Some wholesalers collect POF from serious buyers when they join the buyers list, which our guide to finding cash buyers covers, so they know which buyers can close. Using that buyer’s letter on your own offer, without their permission and without telling the seller who the money belongs to, is where trouble starts.
A partner or lender who will close if the assignment fails
Some wholesalers partner with an investor or lender who agrees in writing to buy or fund the deal if no end buyer appears. That arrangement, often set up as a joint venture, can support a legitimate POF letter in the partner’s name. Get the commitment in writing first, and make sure the partner knows their letter is being shown.
The line you cannot cross
Websites still offer instant “proof of funds letters” from lenders you have never spoken to, and forums still trade edited bank statements. Using either is not a gray area. A document that misstates who has money, or how much, is a false statement made to get someone to sign a contract.
The exposure is real. Sending a false document by email can bring in the federal wire fraud statute, 18 U.S.C. § 1343, which carries up to 20 years in prison, or up to 30 years and a $1,000,000 fine where a financial institution is affected. State fraud and deceptive-practice laws apply too, and a seller who relied on a fake letter has an obvious civil claim. Even short of prosecution, a listing agent who catches one fake letter will not take your calls again.
Some states also require you to tell sellers up front that you intend to assign or resell. Oklahoma, for example, requires written disclosure that the wholesaler intends to sell their equitable interest for more than the seller is being offered, along with a two-business-day cancellation right, under 59 O.S. § 858-314. Rules differ by state, so check the state guide for yours. A proof of funds letter that implies you are the long-term buyer sits awkwardly next to a disclosure that says you plan to assign.
How to get a legitimate proof of funds letter from your bank
- Decide which entity is buying. If your purchase agreements name your LLC, the letter should cover an account in the LLC’s name.
- Ask your branch or relationship manager for a balance verification or proof of funds letter. Some banks have a template; others will write one on request.
- Ask for a “funds available of at least” amount rather than your exact balance if the bank allows it. You don’t need to show a seller everything you have.
- Confirm the verification contact. Make sure the phone number on the letter reaches someone who will confirm it.
- Refresh it monthly while you are actively making offers, and keep the old ones out of circulation.
Worked example: one deal, three honest options
All figures are hypothetical. A vacant three-bedroom is listed “as is” and the listing agent wants proof of funds with every cash offer. You estimate an ARV of $260,000 and repairs of $45,000. Using the 70% rule as a starting point (run your own numbers in the MAO calculator), your end buyer’s maximum is about $137,000, and you want a $12,000 assignment fee, so you offer $125,000.
| Option | Letter you send | What you tell the agent | Risk if your buyer falls through |
|---|---|---|---|
| A. Your cash | Bank letter showing at least $130,000 | You are the buyer, closing in 21 days | You may need to close yourself or cancel within a contingency |
| B. Double close | Transactional funder’s conditional letter | Funding is committed for a simultaneous close on a resale | No end buyer means no funding; you lose time and goodwill |
| C. Partner backstop | Partner’s bank letter, with their consent | Your partner will fund or take the deal if your buyer doesn’t | Partner closes; you split the profit as agreed |
Each option is defensible because the letter matches the story. The failing version is option D: a letter from a lender you have never spoken to, attached to an offer that says “cash buyer, no contingencies,” with no plan if the assignment fails. That is the version that ends with a cancelled contract, an angry agent and a forfeited deposit. Our guide to earnest money in wholesaling explains how that deposit is usually exposed.
What to say when a seller asks for proof of funds
Off-market sellers rarely ask for a letter, but they often ask the same question in plain words: “Do you actually have the money?” A straight answer works better than a document:
- If you plan to assign: explain that you work with a group of investors who buy homes for cash, that one of them will fund the purchase at closing, and that the title company will hold the deposit and handle the money.
- If you plan to double close: say that you will buy the home and resell it, and that the purchase is funded by a short-term lender that closes on the same day.
- Either way: give the seller the title company’s name and number. A neutral third party holding the money is more reassuring than any PDF.
Practice this the same way you practice the rest of your offer conversation. Sellers who hear a confident, specific answer rarely ask for paper.
Checking the proof of funds your buyers send you
The same scrutiny runs the other way. When a buyer on your list sends you their letter, verify it before you assign a contract to them:
- Look up the bank or lender’s main phone number yourself rather than using the one printed on the letter.
- Confirm the name on the letter matches the buyer or entity that will sign the assignment.
- Check the date, and ask for a new one if it is more than a few weeks old.
- Ask how they closed their last two purchases. Recorded deeds in the county records will confirm it.
- Require a non-refundable deposit with the title company once the assignment is signed. Real buyers rarely object.
When a proof of funds letter won’t save the offer
- Your price is wrong. A letter makes a good offer more credible. It doesn’t make a lowball offer acceptable.
- The listing prohibits assignment. Some listing agents and most REO addenda restrict assignment. No letter fixes that; a double close might, if the contract allows resale.
- Your state limits wholesaling activity. Where marketing a contract requires a license or disclosures, a POF letter doesn’t change those rules. Our guide to licensing for wholesalers covers that.
- You have no buyer. If you can’t name three buyers who would take the deal, a letter only delays the moment you have to admit it.
A simple proof of funds file to keep ready
Agents who ask for proof of funds tend to ask on short notice, often with a highest-and-best deadline the same day. Keep a small folder current so you can answer in minutes without improvising:
- A bank letter in your buying entity’s name, dated this month.
- Your LLC’s formation document or certificate of good standing, in case the agent asks who the entity is.
- A one-paragraph description of how you close: title company, typical timeline, and whether you assign or double close.
- A current letter from your transactional funder or backstop partner, if you use one, with their written permission to share it.
- A short list of recent closings, if you have them, with addresses the agent can look up.
Date every file and replace it monthly. An agent who receives last quarter’s letter will assume your balance has changed, and they will usually be right.
Common mistakes with proof of funds
- Name mismatch. The offer is in your LLC’s name and the letter is in your personal name, or the reverse. Agents notice.
- Overstating the amount. Showing far more than the purchase price invites questions about why you need to assign.
- Unmasked account numbers. Send what proves the balance and nothing else.
- Stale letters. A letter from three months ago tells the agent you aren’t active.
- Sharing someone else’s letter without permission. Even if the money is real, it isn’t yours to show.
Proof of funds questions
Can I get a proof of funds letter with no money?
You can get a conditional funding letter from a transactional or private lender, and that is legitimate if you describe it as conditional funding. You can’t honestly get a letter saying you have cash you don’t have.
How recent does a proof of funds letter need to be?
There is no national rule. Many agents and asset managers want it dated within about 30 days, and some want it dated within the week of the offer. Ask before you send.
Do off-market sellers need proof of funds?
Usually not in writing. They need to trust that you’ll close. A clear explanation of how the deal closes, a reputable title company, and a deposit held in escrow do more for that trust than a letter.
Can retirement accounts count?
Some agents accept brokerage and retirement balances, others want liquid cash in checking, savings or money market accounts. Retirement funds can carry taxes and penalties to withdraw, so most sellers treat them as weaker proof.
