Should I be wary of a broker who won't show me comparable sales?

It's worth asking why, though there can be legitimate limits on what a broker can share. Details of other sellers' transactions are often confidential, and a broker may not be free to disclose specific figures or identifying details from past deals without breaching confidentiality obligations to those earlier clients — that's not evasiveness, it's a genuine restriction most reputable brokers operate under.

What's different is a broker who can't or won't discuss general market patterns at all — how businesses in your industry have generally been priced or positioned, without naming names or disclosing another client's confidential figures. A broker with real experience should be able to speak in general terms about what they've seen work, even while protecting specific past clients' confidentiality. If a broker seems unable to discuss anything beyond your own listing, or their answers feel evasive rather than appropriately careful, that's a fair reason to ask more pointed questions or look elsewhere. A Treadstone business lawyer can't substitute for market knowledge, but can help you evaluate the listing agreement itself once you've chosen a broker.
