How do I tell whether a commercial buyer who asked for a second look is actually re-evaluating or just stalling me out

The utility bill request is the one I'd trust, nobody pulls 24 months of bills to feel busy.

A second document request in commercial is almost always a real signal, but the type of document matters more than the number of requests.

The rent roll rerun is ambiguous. Buyers pull it again to verify unit-level vacancy, lease expiration stacking, or month-to-month exposure. That could mean they are building a model or confirming a concern. The utility bills request is more specific. Twenty-four months means they want to see seasonality and they are underwriting expense reimbursement structure, which usually means they are stress-testing NOI before they go to their investment committee or their lender. That is not a stalling behavior. Stalling looks like asking for documents you have already sent, or requesting items that do not affect underwriting, a third copy of the T12 they already have, photos of units they have never seen.

The assumption doing the most work in your read is that buyer silence on the other two equals disengagement. In commercial, silence between document requests often means someone is in their model. I would not weight it the way you would in residential.

Your actual risk here is timeline, and you should manage it directly. With 11 days on the inspection period, you need a soft close from at least one of those three buyers within five or six days to have any room to work. The way to test real interest without burning a relationship is to send a short update to all three: you have multiple parties still in diligence, you are managing a seller timeline, and you want to know if they are positioned to move to a number by a named date. Real buyers respond to that with a timeline. Stalling buyers go quiet or ask for something else.

If one of the utility-bill buyers comes back with a number or a counter, your seller conversation about a short extension becomes much easier because you have evidence of momentum, not just your read.

What is the assignment fee structure you are targeting on this one, and did your contract with the seller include a standard inspection-period language or something custom?

The rent roll re-request and the utility bill pull are two different signals and you should not treat them the same way. Asking for the rent roll a second time usually means the buyer is trying to reconcile something that did not line up on first pass, a tenant whose lease term looked off, a unit mix that did not match the OM, something specific that snagged. That is a buyer doing real work. Asking for 24 months of utility bills is a different move entirely: that buyer is building an expense model from the ground up, which means they are stress-testing your 8.4 cap against a scenario where the owner-paid utilities are materially higher than whatever you disclosed. Both of those are forward motion, but the utility buyer is farther along in their process and is probably closer to a number, even if that number comes in with a retrade attached.

The way to tell stalling from underwriting in commercial is to put a deadline on the next document delivery and see who responds and how fast. Send both buyers a clean package, the rent roll with lease abstracts attached if you have them, and the utility bills with a note that you are tracking your inspection clock and need to know their timeline by a specific date, something like five days out. A real buyer comes back with a question or a number. A staller either goes quiet again or asks for something else that does not advance a decision. You have 11 days, which is enough time to run this test and still request an extension with something concrete to show the seller, an LOI or a number in negotiation, rather than asking for more time with nothing behind it. The extension conversation with your seller is much easier when you can say a buyer has the utility data and is modeling a number than when you are asking on faith. What did your contract with the seller say about assigning or re-marketing if no buyer performs?
