A few years back I dealt with this annoying unruly buyer, who had his eyes on one of my properties. We talked about him buying it a few times, but he wasn't fully set on it at first. When he finally decided to go all in, he decided to jump out the deal the same day. He implied we were trying to cheat him, and that the house was too expensive, yet he had 100% agreed to the final listing price. I think it was because he didn't like that he had to pay some money down. I told him that's how things go, but he decided to just back out of the deal. He wasted months of my life and so on. So, after that, we decided that we'd never work with him again and moved our separate ways. It just wasn't worth it.
Anyway, did you ever have to deal with someone like that?
Really the only way is to either explain that the deal is off, or if you have already sold, explain that if he continues, that will be considered harassment. I've never had issues with a buyer like that though, so I can't really say. But usually if someone acts up, I decline to sell to them and explain they can ask a different realtor to take over. I do not deal with it, so I let it go as soon as possible.
I have had people try to spin my words against me. I have since stopped dealing with buyers one on one and have a middle man work between us, a realtor of sorts. It is a lot easier and less hassle. Plus, if I get a real crazy person, I don't have to deal with being stalked over it. Yes, that has happened once. I got a man arrested because he vandalized a home I would not sell to him and keyed my car.
You're bound to deal with a few bad ones over the years. I've dealt with my fair share. Some I've dealt with who don't have the money to buy, or they demand something be updated or changed, etc. I've never had a really awful buyer/home owner though. Just people who get a bit cranky when they don't get their way.
I read some horror stories online from people selling homes to folks who made everything difficult. I would imagine for some, because this is such a huge investment, they can end up being a pain in the backside because they are being overly cautious and indecisive.
