- A financed offer needs two proofs: statements or a bank letter for your down payment and closing costs, and a lender letter for the loan. On the worked $246,000 flip, that's $47,016.50 of cash behind a $261,100 loan.
- Investor lenders pre-qualify quickly: Kiavi on a soft credit pull, New Silver after automated underwriting it says takes under 5 minutes. None can commit before valuation, title, insurance and final underwriting; LendingOne's bridge page says outright it's not a commitment to lend.
- Names and dates get checked. Auction.com rejects proof in a name that doesn't exactly match the contract, and asks for proof dated within 30 days of the completed contract.
- In September 2026, 27% of existing-home sales were all cash, per NAR. Your letter competes with those buyers, so tie it to the address and price and write a closing date your lender can meet.
- Rented or doctored proof of funds is fraud, not a shortcut. Federal prosecutors alleged in 2009 that one firm charged $40,000 to ‘lease’ a $2 million balance it never held.
A proof of funds letter in real estate tells a seller you can close. When you're buying with an investor loan, a bank statement alone doesn't do that, and neither does a lender's letter alone. The seller needs to see the cash for your share and a lender standing behind the rest. Competition sets the bar: in September 2026, 27% of existing-home sales were all cash, and individual investors and second-home buyers made up 20% of transactions, per NAR. Here's what to send, what a lender can honestly promise before it has valued the property, and how to spot the fake proof-of-funds services that target investors.
Two proofs behind every financed offer
| Item | Proof of your cash | Proof of the loan |
|---|---|---|
| What it covers | Down payment, earnest money, points and closing costs | The loan: purchase money plus any rehab holdback |
| Who issues it | Your bank or brokerage: a statement, or a letter on its letterhead | The lender: a pre-qualification or pre-approval letter, or a term sheet |
| What makes it credible | Your name or your entity's, a current date, the available balance | The lender's name and a direct contact, the address, the amount and the conditions still open |
| What it can't do | Prove a loan you haven't been offered | Prove you hold the cash for your share |

Whoever issues the proof has to hold the money or be lending it. Virginia REALTORS' staff counsel made the point in 2023: where a contract asks for verification from a third party holding the buyer's assets, a financial advisor's letter based on the buyer's own word doesn't qualify. A banker who can see the account does.
Your cash: what sellers and auction platforms check
For your share, the plainest proof is the strongest: a recent statement or a letter from the institution holding the money. Auction platforms publish the strictest rules, and they show what a careful seller's agent looks for:
- The same name as the contract. Auction.com rejects proof when the name doesn't exactly match the buyer or purchasing entity on the contract. If you're buying in an LLC, show the LLC's account, or be ready to show how your personal funds will reach it.
- A current date. Auction.com asks for proof dated within 30 days of the completed contract; LoopNet's auction help asks for the account holder's name, a current date and the available balance.
- Enough for your share. On a financed Auction.com purchase, the proof has to cover the earnest money deposit and the down payment. Some of its listings refuse hard money loans altogether, so read the terms before you bid.
- Permission for someone else's money. LoopNet wants written authorization from the account holder when the account isn't yours, and the entity's formation document when it belongs to a company.
Redact account numbers, not names or balances. OfferMarket's guide for sellers says buyers should be allowed to blank out details they consider sensitive, but a seller can't credit a balance you've hidden.
Your lender reads the same statements more closely than the seller does. OfferMarket asks for each guarantor's two most recent statements, counts retirement accounts at 50%, and wants liquid assets equal to cash to close plus 25% of any rehab budget. Rehab Financial asks for three consecutive months of statements, personal and business. A balance that appeared last week will be questioned, so move money into the account you'll show well before you apply.
The loan: pre-qualification letters, POF letters and term sheets
Investor lenders issue several documents before closing, and the names overlap. What matters is what each one rests on:
| Document | What it usually rests on | What it can't tell a seller |
|---|---|---|
| Pre-qualification letter | Your answers, a soft credit pull and the program's leverage | Whether the house will value, or the file will clear |
| Pre-approval or exposure limit | A credit pull plus liquidity you've documented | The loan on this house, until it's valued |
| Lender proof-of-funds letter | Automated or manual review of your profile and the deal you described | Anything beyond what the lender actually checked |
| Term sheet | Proposed rate, points, leverage and conditions for this deal | Final approval: conditions remain open |
| Clear to close | Valuation, title, insurance and underwriting completed | Little: only closing items remain |

Published examples in October 2026. Kiavi runs a soft credit pull when you pre-qualify, then lets you download a pre-qualification letter from its online tool. Lima One checks credit with a soft pull to preapprove you and a hard pull only when a loan goes in; for builders, it also sets a six-month exposure cap at as much as ten times the liquidity you show. New Silver issues a proof-of-funds letter and a preliminary term sheet online after automated underwriting it says takes under 5 minutes, once you pay an application fee. LendSure says its construction pre-quals typically take 24 hours.
What an investor lender can't promise yet
An investor loan is sized on the property, so the lender can't finish until it knows what the property is worth. Kiavi lays out the order. You pre-qualify and find a property, then submit. Processing takes as little as 4 days and includes title, insurance and a property inspection. A feasibility team checks your scope of work. Its in-house valuation team sets the ARV from sales within a mile in the last 6 months, in as little as 5 days. Then underwriting. Any of those steps can change the loan, which is why these stay open when you make the offer:
- The value. A letter can quote leverage, such as 85% of price or 75% of ARV. The dollars depend on the valuation.
- Title and insurance. No lender funds over an unreleased lien or without the policy it requires.
- Your cash. Statements are verified at application, not at pre-qualification.
- The rate. Pricing can move until the loan is locked or the documents are drawn.
- Final approval. LendingOne's bridge page says it outright: not a commitment to lend, and all offers of credit subject to approval.
Read any letter for its conditions and its expiry date. A useful one names what's still open, so the seller's agent knows exactly what could go wrong, and a letter that promises everything is the one to doubt.
Worked example: the package behind a $246,000 flip offer
You're offering $246,000 on a house that needs $52,000 of work and has an ARV of $375,000. The lender's program lends 85% of the price plus 100% of the rehab, up to 75% of ARV. Points are 1.5%, closing costs are assumed at $6,200, and the $5,000 earnest money deposit is credited at closing. Illustrative, not a quote.
| Item | Amount |
|---|---|
| Purchase price | $246,000 |
| Loan toward the purchase, 85% | $209,100 |
| Rehab holdback, 100% | $52,000 |
| Total loan | $261,100, under the $281,250 ARV cap (75% of $375,000) |
| Down payment | $36,900 |
| Points, 1.5% of $261,100 | $3,916.50 |
| Closing costs (assumed) | $6,200 |
| Cash to close, earnest money included | $47,016.50 |
| Liquidity under OfferMarket's rule: cash to close plus 25% of rehab | $60,016.50 |

So the offer goes in with two documents: a lender letter for this address showing up to $209,100 of purchase money and a $52,000 rehab holdback, and bank proof of at least $47,016.50. Showing $60,016.50 is better, since that's what a lender using OfferMarket's rule will look for at application. Proof that stops at the $36,900 down payment leaves the agent guessing about points and closing costs. The full cash picture, including the rehab gap and carry, is in cash needed to flip a house.
How to present it with the offer
- Ask for a letter for this offer. Address, price and loan amount, not your maximum. A letter for $400,000 behind a $246,000 offer tells the seller your ceiling.
- Use one buyer name everywhere. The contract, the lender letter and the bank proof should name the same buyer, usually your LLC.
- Write a closing date your lender can meet. Kiavi advertises bridge loans that close in as few as 7 business days, LendingOne quotes 10–14 days, and Lima One pitches 7–10 business days against the month a slower buyer needs. Then allow for title; see closing an investor loan fast.
- Give the agent a way to verify. The loan officer's name and direct number. OfferMarket tells sellers to confirm with the lender that the buyer's credit and liquidity were reviewed, so make that call easy.
- Put the earnest money with a neutral holder. Usually a title company or attorney acting as escrow agent, with the refund conditions written into the contract.
- Decide on the financing contingency deliberately. Dropping it makes the offer read like cash, but it puts your earnest money behind a loan nobody has committed to yet. Ask your agent or a real estate attorney how your state's contract handles it.
Red flags: rented balances, edited statements and letters from nobody
Offers to sell proof of funds circulate wherever investors gather. Treat every one as a trap:
- ‘Leased’ or rented funds. In 2009, federal prosecutors in Brooklyn charged nine people over a firm that, they alleged, sold ‘leased funds’ it never provided and printed fake proof-of-funds documents on bank letterhead, with two bank employees confirming the false balances by phone. Fees allegedly ran from $40,000 for a $2 million account, and customers lost more than $7 million, the government said.
- Edited statements. A 2023 California Department of Real Estate accusation alleged that a buyer's agent altered his own credit union statement to show the buyers' names and a $44,637.61 balance, and that the seller accepted the offer relying on it.
- A letter from someone who won't lend. If the issuer has no loan program, pulled no credit, never saw the deal and is charging for the letter itself, the letter proves nothing, and an agent who calls will find out.
- Pressure not to verify. A real lender wants the seller's agent to call.
OfferMarket's guide for sellers warns that a fake pre-approval or proof of funds is easy to produce, so assume the other side will check. The legal stakes are serious. Federal law makes a knowingly false statement meant to influence a mortgage lending business, a term that includes private mortgage companies, punishable by up to $1,000,000 in fines and 30 years in prison (18 U.S.C. § 1014). For questions about your own situation, talk to an attorney.
