When you receive an offer on a home in Cincinnati or Dayton, OH, a mortgage preapproval and proof of funds answer two different questions. At Ohio Cash Buyers, we encourage sellers to look beyond the document title and verify what the buyer is actually relying on to complete the purchase.
A mortgage preapproval indicates that a lender is tentatively willing to finance a buyer subject to additional underwriting and property requirements. Proof of funds is used to support a claimed cash purchase by showing available financial resources. Neither document guarantees that a transaction will close, so sellers should also review the purchase contract, contingencies, earnest money, title requirements, and the credibility of the buyer’s financial documentation.
Why Do Sellers Confuse Proof of Funds with a Preapproval Letter?
Both documents come on official letterhead. Both reference a buyer’s financial ability to purchase a home. And both get handed over during the early stages of a sale. That overlap in timing and appearance is exactly why so many sellers treat them as interchangeable.
They Look Similar on the Surface
A mortgage preapproval letter typically comes from a bank or lender. It states that a buyer has applied for a loan and met initial credit and income requirements. A proof of funds letter also comes from a financial institution, but it confirms that a buyer has actual liquid money available right now.
To a seller reviewing documents quickly, both feel like a green light. The difference only becomes clear when you understand what each document is actually confirming.
One Depends on a Third Party
A preapproval letter is not a promise. The lender can still deny the loan if an appraisal comes in low, if the buyer’s financial situation changes, or if underwriting finds a problem. That is a third party sitting between you and your closing date.
A proof of funds letter removes that third party entirely. It shows the money exists in a verifiable account right now, not as a conditional promise tied to a future loan approval. For sellers who want certainty, that distinction matters a great deal.
The Source of Confusion
Real estate listings often say “proof of funds or preapproval required.” That phrasing accidentally trains sellers to view the two as equals. Buyers who need financing submit a preapproval letter. Buyers paying cash submit a proof of funds letter. Treating them the same creates a false sense of security when you are evaluating a cash offer.

Which Document Actually Guarantees a Cash Close?
The short answer is that only a proof of funds letter comes close to guaranteeing a cash close. Even then, sellers should know what makes a proof of funds letter valid and what red flags to watch for.
What a Valid Proof of Funds Letter Contains
A legitimate proof of funds letter will include several key elements. Look for all of these before accepting any cash offer:
- The name of the financial institution on official letterhead
- The account holder’s name matching the buyer making the offer
- A current account balance sufficient to cover the purchase price
- The date of the letter (current enough to reasonably reflect the buyer’s present financial capacity)
- A signature or stamp from a bank representative
If any of these pieces are missing or mismatched, that is a reason to ask questions before moving forward.
Why a Preapproval Letter Is Not a Cash Closing Guarantee
A no-financing-contingency clause in a contract is often paired with a preapproval letter, but those two things do not create the same security as a cash offer. A buyer who removes their financing contingency is still trying to get a loan. If the loan falls through, the deal can still collapse, even without a contingency in place.
A true cash buyer does not need a lender at all. A bank requires no appraisal, no underwriting timeline, and no risk that a lender pulls back approval. That is the essential difference between a lender letter and a bank letter showing liquid funds.
When Proof of Funds Is Still Not Enough
Even a valid proof of funds letter does not mean the buyer will perform. Some buyers show funds in one account while planning to use other money for the actual purchase. Others present letters from accounts they do not fully control.
Asking to see a recent bank statement alongside the proof of funds letter is a reasonable and common request. It adds a second layer of confirmation that the money is real, accessible, and under the buyer’s control.
How Should Sellers in Ohio Ask for the Right Document?
Asking for the right document does not need to feel confrontational. It is a normal part of any real estate transaction, and any serious cash buyer will be prepared to provide it.
What to Say When Requesting Verification
You or your agent can simply state that you require a proof of funds letter from the buyer’s bank or financial institution before seriously reviewing the offer. Be specific about what you need:
- A letter on official bank letterhead
- Showing a balance equal to or greater than the offer price
- Signed by a bank representative
This is how to verify a cash home buyer the right way, and it protects you from wasting time on offers that cannot close.
Frequently Asked Questions
What is the difference between a proof of funds letter and a preapproval letter?
A proof of funds letter confirms that a buyer has liquid cash currently sitting in a bank account, ready to be used for a purchase. A mortgage preapproval letter shows that a lender has conditionally agreed to issue a loan, which means the purchase still depends on financing approval. Only the proof of funds letter applies to a cash transaction.
How do I know if a proof of funds letter is legitimate?
A valid letter will appear on official bank letterhead, include the buyer’s name, show an account balance that covers the purchase price, and include a recent date and a bank representative’s signature. We recommend requesting a recent bank statement as a secondary confirmation, which is a standard and accepted practice in real estate.
Can a cash buyer in Ohio back out after providing proof of funds?
Providing proof of funds does not legally bind a buyer to complete the purchase. The contract terms, earnest money provisions, and contingency clauses are what govern the transaction. Sellers should work with a real estate attorney or agent to ensure the purchase agreement is structured properly so the earnest money provides meaningful protection if the deal does not close.
