My teenage son and his friends kept removing the for sale sign from a cute girls house in our neighborhood. This was in the 2000's so it was funnier than it would be these days.
my niece was selling their house the same time. I was moving out of state and had a schedule to keep my niece had outgrown their house. We had a local buyer ready to begin the process had put earnest $ down. Unbeknownst to us my niece who lived down the street poached them offering closing costs etc to basically swap houses. Let's just say family get togethers aren't great
I almost did this. House on our street had been condemned due to meth. Got cleaned and back on market. Not sure if buyers knew that
