When to pass on a stalled deal?

Hi all,

I'm wondering if anyone has advice or experience regarding "stalled" deals, especially brokered deals. When on paper a deal looks interesting, financials are great, but the broker keeps delaying site visits, takes weeks to respond to questions, etc. Just sort of taking their time, but it seems like everything is "just a couple of weeks away" from site visits/offers.

My thoughts are:

- They could be having a hard time generating enough interest for whatever reason and are trying to get more interested buyers in before asking for offers.
- They don't like me as a buyer for some reason.
- The owner is disengaged and the broker is not doing a great job of bringing them along.
- If this is indicative of how the diligence process will go, is it even worth pursuing?

Any thoughts or advice are appreciated!
