Experiences with pepple responding your selling ad

I had a guy call me giving me a story about his home burning down in the Southern California fires. He had no where to go. Wanted me to help him out with a low price he offered, too low I said. He then started bumping his offer up.He wanted to come and see it. When he was 2 hours late, I called him and got a weird response from him. In one sentence he said he ran into heavy traffic, then said he did not have the money nor could he afford the gas(50 miles away). I knew he was nuts and said o.k. and hung up. He did not have a home that burned. I was able to sell to a very honest gentleman from out of state. Only took one week on Craigslist to sell. I was getting ready to cancel the craigslist ad and go another selling route. Thank for all your replies!
