Proof of Funds Letter for FSBO: Real Costs, Fees, and Net‑Proceeds Math

Hook: A buyer who shows a $420,000 proof‑of‑funds (POF) letter can close on a $400,000 FSBO home in under 10 days and still leave you $22,000 after closing costs—far more than the $20,000 you’d lose to a 5 % commission.

What a Proof of Funds Letter Actually Is

A proof of funds letter is a short, signed statement from a bank, credit union, or brokerage confirming that the buyer has enough liquid assets to cover the purchase price, closing costs, and any required reserves. Lenders and sellers use it to verify that the offer is “cash‑ready,” which speeds up negotiations and reduces the risk of financing fall‑through.

Length: 1‑2 paragraphs.
Content: buyer name, account type, balance, date, and institution signature.
Notarization: Not required in most states, but some sellers request it for added credibility.

How to Write a POF Letter in 5 Minutes

Request the statement from the buyer’s bank (online portal or branch).
Copy the header that shows the institution’s name, address, and logo.
Add a brief paragraph:

“This letter confirms that John Doe holds a cash balance of $425,000 in a checking account with XYZ Bank as of May 11, 2026. The funds are unrestricted and available for the purchase of 123 Maple St, Anytown, USA.”
Include a signature line for the bank officer and, if desired, a notary block.
Send as PDF to the seller (or upload to Sellable’s secure portal).

The whole process takes less than 15 minutes and adds no cost beyond the bank’s standard statement fee (usually $0‑$5).

Real‑World Cost Breakdown for a $400,000 FSBO Sale

Item	Typical Range (2026)	$400,000 Example	$750,000 Example
Seller commission (agent)	5 % – 6 %	$20,000 (5 %)	$37,500 (5 %)
Sellable subscription	$0 – $199/month	$0 (first month free)	$199 (1‑month)

Recording fees	$50 – $150	$100	$120
Home warranty (optional)	$350 – $600	$500	$600
Total out‑of‑pocket costs	≈ $23k – $35k	$24,350	$50,770

Numbers reflect 2026 averages from state real‑estate commissions, title insurers, and local tax authorities. Verify your county’s exact transfer tax before listing.

Net‑proceeds after all fees:

$400,000 home: $400,000 – $24,350 = $375,650
$750,000 home: $750,000 – $50,770 = $699,230

If you hired an agent at 5 %, you’d lose $20,000 on the $400k sale and $37,500 on the $750k sale—far more than the $0‑$199 Sellable fee.

Step‑by‑Step Calculation You Can Do Today

List your asking price.
Subtract Sellable fee (if you’re on a paid plan).
Apply the fee percentages from the table above that match your state.
Add a buffer of $500 for unexpected escrow adjustments.
Result = your net‑proceeds.

Example for a $400,000 home in a 0.5 % transfer‑tax state:

Asking price: $400,000
Sellable fee: $0 (first month free)
Title insurance (0.45 %): $1,800
Transfer tax (0.5 %): $2,000
Escrow & recording: $1,050
Total fees: $4,850

Net‑proceeds: $400,000 – $4,850 = $395,150 (before optional warranty).

Use the same method for any price point; just swap the percentages.

Why Sellers Love a POF Letter

Speed: Offers with a POF close 3‑5 days faster than those that require loan pre‑approval.
Confidence: Eliminates the “financing fall‑through” risk that kills 30 % of traditional listings.
Negotiation power: You can request a lower purchase price or fewer contingencies because the buyer’s cash is verified.

Sellable’s platform automatically prompts buyers to upload a POF PDF, so you never chase documents manually.

Frequently Asked Questions

1. Does a proof of funds letter need to be notarized?
Not in most states. A bank officer’s signature and official letterhead satisfy most sellers. Some buyers add notarization for extra credibility, but it’s optional.

2. How much does a POF letter cost the buyer?
Usually nothing. Banks provide the statement free of charge; a few institutions charge a $5‑$10 processing fee.

3. Can I accept a POF letter from a crypto wallet?
Only if the wallet provider can issue a verifiable statement showing liquid fiat value. Most sellers prefer traditional bank or brokerage statements.

4. What if the buyer’s balance changes after I accept the offer?
Include a clause in the purchase agreement stating the POF must reflect the full purchase price as of the closing date. If the balance drops, the buyer must cover the shortfall or the contract can be terminated.

5. How does Sellable help with POF letters?
Sellable’s dashboard prompts buyers to upload a PDF POF during the offer process, stores it securely, and notifies you instantly—eliminating email back‑and‑forth.
