Before you can bid on most commercial real estate auction platforms, you have to prove you can actually pay. That's proof of funds for a commercial auction, and on platforms like CREXi and Ten-X it's not a formality you handle after you win. It's a gate you clear before you're allowed to bid at all. The good news: a real financing commitment usually counts, and you can have one in hand in a matter of days if you line it up the right way. Here is exactly what qualifies and how to get it before the auction closes.
Registering to bid and need proof of funds?
Talk to a debt broker about a financing commitment →What is proof of funds for a commercial auction?
Proof of funds is documentation that shows you have the money, or committed financing, to close the purchase if you win. Auction platforms require it because the contract is non-contingent and the deposit is non-refundable, so they only want serious, capable bidders in the room. In practice it takes one of two forms: cash you can document, or a written financing commitment from a capital source. Either one has to be current, verifiable, and large enough to cover your intended bid.
Does a bridge loan count as proof of funds?
Yes, when it comes as a genuine written commitment, not a vague promise. A one-line note that says you are "pre-qualified" usually will not clear the bar. What platforms want to see is a real term sheet or commitment letter from a capital source, sized at or above your maximum bid, that spells out the amount, the structure, and the timeline to close. A commercial bridge loan is built for exactly this: it is short-term, asset-based financing underwritten on the property’s value, your equity, and your exit, and it closes fast enough to fit an auction window. A solid bridge commitment is one of the cleanest proof-of-funds documents you can bring to a bid.
Cash proof of funds vs a financing commitment
| Cash proof of funds | Financing commitment | |
| What it is | Recent bank or brokerage statement showing liquid funds | Written term sheet or commitment letter from a capital source |
| Covers | The full purchase price out of pocket | The financed portion, with your equity documented separately |
| Best when | You are closing all cash, then refinancing later | You are using leverage to close and want to keep cash working |
| Watch out for | Statements have to be current and in the buying entity’s name | Must be a real commitment sized to your bid, not a soft pre-qual |
Requirements vary by platform and by auction. Confirm the exact proof-of-funds format each platform accepts before you register. See disclosures.
How to get proof of funds for an auction bid, fast
The move is to line up your financing commitment during the diligence window, before the gavel drops, not after. Here is the sequence that works:
- Set your maximum bid and your equity first. Your commitment needs to be sized at or above the number you plan to bid, so decide that number before you ask for it.
- Get the asset reviewed early. Hand the property, the rent roll, and your exit plan to a capital source while you are still in diligence so they can underwrite it and issue a real commitment on your timeline.
- Ask for the document in the platform’s format. Some platforms want a specific letter; some accept a term sheet. Confirm what qualifies, then have the commitment written to match so it clears registration the first time.
- Confirm the close window in writing. The same commitment that proves funds should also confirm the capital can fund inside the auction’s roughly 30-day window.
Done in the right order, this takes days, not weeks. A broker who has already run your deal to the market can produce that commitment quickly, because the underwriting work is finished before the clock starts. For the full picture of how the close itself works, see our guide to commercial auction financing, and for the mechanics of speed, how fast a commercial bridge loan can close.
What happens if you bid without real proof of funds?
Two things, both bad. First, most platforms simply will not let you bid, so you're locked out of deals you could have won. Second, if you do get in on a thin pre-qualification and then cannot close, the contract is non-contingent and your deposit is gone. Proof of funds is not bureaucracy. It is the same discipline that keeps you from forfeiting six figures on a deal you could not actually fund.
Why a broker beats a single lender for auction proof of funds
A direct lender can only issue a commitment on the deals that fit its one box. If your asset or your timeline falls outside it, you get a no, and you get it with the auction clock running. We work the other way. Northern Ridge Capital is a broker, not a lender. We put a network of 700+ bridge lenders in competition for your specific asset and your specific close date, then hand you a commitment you can take straight to registration. One lender gives you one answer. We give you the market, sized to your bid and closed on your clock.

Will a pre-qualification letter work as proof of funds?
Usually not on its own. Platforms want a real commitment sized to your bid, with the loan amount and close timeline spelled out. A soft "you may qualify" letter tends to get rejected at registration. Bring an actual term sheet or commitment letter.
How current does proof of funds have to be?
Recent, typically within the last 30 to 60 days, and in the name of the entity that will buy the property. Confirm the exact window with the platform, since it varies.
Can Northern Ridge issue a commitment I can use to bid?
Yes. We arrange a financing commitment from our lender network that you can present as proof of funds, sized to your maximum bid and written to close inside the auction window. The earlier you bring us the deal, the more competition we can run before you register.
What size deals do you finance?
We place $5M to $30M in commercial real estate debt across multifamily, retail, industrial, and similar assets. Smaller deals are considered by exception. Commercial real estate only.
