POF (Proof of Funds)
Also known as: proof of funds, proof of funds letter, POF letter, bank letter
Proof of funds (POF) is documentation that demonstrates a buyer has sufficient capital available to close a mortgage note purchase. In the secondary mortgage note market, sellers and brokers use POF to separate serious buyers from tire kickers before investing time in a transaction. A credible POF tells the seller that you can actually fund the deal — not just talk about it.
What Qualifies as Proof of Funds
Several document types are accepted as proof of funds in the note industry:
| Document Type | Description | Common Use |
|---|---|---|
| Bank statement | Recent statement showing available balance in a checking or savings account | Most common; easy to produce |
| Financial institution letter | A letter from your bank confirming available funds on letterhead | More formal; preferred by some institutional sellers |
| Brokerage or investment account statement | Statement from a brokerage showing liquid holdings | Used when capital is held in investment accounts |
| Self-directed IRA statement | Custodian statement showing available cash balance | Required when purchasing notes inside a retirement account |
| Line of credit confirmation | Letter confirming an approved and available credit facility | Less common; some sellers accept it |
When providing a bank statement, most buyers redact the account number — showing only the last four digits — and any unrelated transactions. The seller needs to see the balance and the account holder's name, not your personal spending history.
When Proof of Funds Is Required
POF comes into play at several points in the note acquisition process:
With Your LOI
When submitting a letter of intent (LOI), attaching proof of funds strengthens your offer significantly. This is especially important when working with a new seller for the first time. The seller does not know you, has no track record of working with you, and needs a reason to take your offer seriously. A POF provides that reason.
Not all sellers require POF with the initial offer — particularly professional sellers who trade regularly and have established relationships with their buyer base. But including it never hurts, and omitting it when a seller expects it can disqualify your bid before it is reviewed.
During Seller Vetting
Many sellers and brokers request POF before they will share a data tape or grant access to their inventory. This is a gatekeeping function — they want to ensure that everyone reviewing their assets has the financial capacity to transact. If you cannot produce POF, you may not get access to deal flow.
At Contract Execution
When the LPSA (Loan Purchase and Sale Agreement) is executed, the seller may require updated proof of funds to confirm that the capital is still available and the buyer can fund within the agreed timeline.
How Much Capital Do You Need?
There is no universal minimum, but a reasonable starting point for a first note purchase is approximately $50,000 in available capital. This provides room for:
- The purchase price of an individual loan (typically $10,000–$40,000 for NPLs)
- Due diligence costs — title searches, BPOs, credit reports ($200–$500 per loan)
- Legal fees — demand letters, potential foreclosure costs
- Servicing setup and ongoing fees
- A reserve for unexpected expenses
Investors with access to larger capital pools — through personal funds, JV partnerships, or self-directed retirement accounts — can provide POF at higher levels, which opens access to larger portfolios and institutional sellers.
Best Practices
- Keep POF current. A bank statement from six months ago does not prove you have capital today. Use statements dated within 30 days of your offer.
- Match the entity. If you are purchasing through an LLC, your POF should show the LLC's account balance — not your personal account. Sellers want to see that the buying entity has the funds.
- Redact sensitive details. Remove full account numbers and unrelated transaction details. Show the balance, the account holder name, and the date.
- Have it ready before you need it. When a deal moves fast, the buyer who can produce POF within hours has a significant advantage over the one who needs a week to get a bank letter. Prepare your POF document in advance and update it monthly.
- Do not overstate your position. Representing capital you do not have access to is a fast way to destroy your reputation in a relationship-driven market. Only submit POF for funds you can actually deploy.
Why POF Matters
In a market built on trust and relationships, proof of funds is the first tangible signal that you are a professional buyer. Sellers remember who produced clean, timely POF — and who made them chase it. Especially for new investors building their first seller relationships, a well-prepared proof of funds letter can be the difference between getting access to deal flow and being ignored.
