Curiouser and Curiouser

Things are getting more curious with my abandoned house lately.
One of the big names I was talking about previously made an offer of $15,000. It doesn't matter that house is assessed at $77,000. When your relatives run the banks, you can do things like that.
The curious part is that this is the second time this month he's made this offer. Both times, a mysterious party from Arizona also expresses an interest in the house.
This time, when he made his offer, the party from Arizona offered to rent the house at half of the going rental rate and said they would pay the full asking price when their house in Arizona sold. Ordinarily, nothing suspicious, except that 2 times now, the timing has been identical, and the people from Arizona cancelled their appointment with the realtor, and so made this offer sight unseen.
I begin to suspect made up people and my problems entering a new phase of stupid and corrupt.
