Be a good neighbor...you may be the one in need next time...

Being a good neighbor is not the same as being a sucker. I would be
very reluctant to give up, permanently, any right to property that I
own. If the owner of the other property is a speculator (which I've had
unhappy experience with), he has no concern with detriment to the
neighborhood or residents. He will make his money and run.
