You did everything about as carefully as you could. I think the lessor is acting very strange. If he had a broker and was using Craigslist to avoid paying the broker, which is what it sounds like, that is just so wrong. You could sue him, but because of the amount it will probably be conciliation court. It sounds like consumer fraud, so you may be able to get the landlord to pay your attorney's fees if you go that way. Talk to his lawyer first, and get your $300 back.
