Offer Submitted- Owner Broker acting shady/unprofessional?

[George G.]

My business partner and I submitted an offer on a $375,000, 10-unit apartment building. Our offer was for $350,000. The property has been on the market for almost 7 months now and all of a sudden the broker says on the phone "Oh, I had a few more offers come in." Typical games. No issues.

Upon speaking with him on the phone, he seemed generally disinterested and at times slightly offensive. We have already qualified for financing and submitted a letter direct from the lender, LOI and our bio (very impressive bio). We'd have no problem qualifying for the property and closing.

Is this standard broker behavior? He also owns the building he is selling. How should we handle this situation?
