Without knowing all the information about each of these homes I would almost guess that they all bought from the builder and either their ARMS adjusted or their taxes went up. 2 of these homes are listed as Short Sales which means they are in pre foreclosure. If you are interested in this neighborhood a Short Sale is a good opportunity to purchase a home that usually will have some front end equity moving in which is a great thing in this market when most properties people are lucky to break even at the price they give and hope their value doesn't decline like a new car the minute they buy the home. Short Sales and foreclosures in poor condition are about the only 2 ways to move in with equity. If you have any questions please feel free to contact me.
