A proof of funds letter answers one question a seller has about you: is this offer real, or am I taking my property off the market for somebody who cannot close?

For a wholesaler, that question is the whole obstacle. You are frequently offering on properties where the seller has been approached by several people who could not perform, and the letter is the cheapest way to separate yourself from them.

What a credible letter contains

  • Who is providing the funds, with real contact details that a listing agent can call
  • The amount available for this transaction
  • The specific property address, or a stated purchase price range
  • The date, recent
  • A statement that funds are available for this transaction, subject to ordinary underwriting and title
  • A signature and a way to verify it

That is all. It is a short document, and its credibility comes from being specific and verifiable rather than from being emphatic.

What makes one worthless

Experienced listing agents discard letters constantly, and generally for the same reasons:

No property and no amount. A generic letter saying you are "qualified up to $500,000" is a marketing document. It tells the seller nothing about their house.

Stale. Anything more than thirty days old invites the question of whether the money is still there.

Unverifiable. No phone number, or a number nobody answers. An agent who cannot confirm the letter treats it as if it did not exist.

Obviously templated. Letters circulating with the same wording under different letterheads are recognised by anybody who sees volume.

Overclaiming. A letter promising unconditional funding regardless of underwriting is not more persuasive, it is less. Nobody in this business lends without seeing the title work, and a letter pretending otherwise signals that the writer is not a real lender.

A redacted bank statement. These get used because they seem stronger. They are weaker: they show a balance on a day, not a commitment to this deal, and they hand a stranger your personal financial position.

Getting one on a live deal

Send the lender:

  • The property address
  • The purchase price, or your offer
  • Your exit: assignment, double close, or a rehab and resale
  • Your timeline

That is enough. I issue a proof of funds letter ahead of the deal so a seller treats the offer as real, and on a straightforward request it goes out the same day.

The important part is that it comes from whoever would actually fund the transaction. A letter from a party who will not be at the closing table is the one that falls apart under a phone call, and a listing agent who has been burned once will make that call.

Proof of funds against an assignment

Worth being precise here, because the two strategies need different things.

Assigning the contract means you never take title. Your buyer closes and you are paid an assignment fee. Strictly, no funds are required from you at all. Sellers still ask for the letter, because they cannot distinguish your intent from anyone else's at offer stage, and increasingly because they have learned that an unassigned contract is a wasted month.

Double closing means you actually buy the property and resell it, usually the same day. Here you genuinely need funds at the A-to-B closing, and the proof of funds letter is describing money that will really move. That is transactional funding, and how the two closings connect is set out in double close funding.

A letter should not misrepresent which of these you intend. If you plan to assign, say so. Agents deal with assignments constantly and the deception is unnecessary.

Where letters actually fall down

Not at the offer. At the closing.

A letter obtained from a lender who was never given the real deal is fine until the file is underwritten, at which point the numbers do not support the loan and the seller learns this a week before closing. That damages you specifically, because listing agents in a given market talk to each other and remember who could not perform.

The way to avoid it is unglamorous: get the letter from a lender you have actually shown the deal to. A letter based on a real look at the property is a letter that survives the closing.

What to have ready

  • The address and the contract or your intended offer
  • Your exit, stated plainly
  • Your timeline, including the seller's own constraints
  • Any known title issues: an estate, a lien, an occupied unit

Deals where something is already known to be wrong are still fundable. Deals where something known was not mentioned are the ones that fail late.

Get the letter

Send the deal over with the address and your offer, and a proof of funds letter goes out ahead of it so the seller treats your offer as real. Transactional funding for a double close runs A to B and B to C, same day.
