Frightening, isn't it? I actually went there and read all the posts on this topic, and I must say there are some very intelligent posters on this subject.
Yes, what about renters? Our place was sold to be turned into commercial property, after it was sold. The new landlord is very cool, and is letting us stay until the end of the year. However, with rents being what they are(former high end mortgage payments), I'm not sure what we're going to do.
Years ago, this part of town was mixed use. They changed to commercial when sold. Feel bad for the people in the trailer park next door.
There is some question whether rentals are residential or commercial. It is a business with contracts, law, and public regulation.
