Also some of the larger homes or estates with the large lots will be very attractive to people wanting "Estate like" homes for a better value. 

You want to make it attractive to the buyer or at least allow them to visualize what may suit their needs best.

Daniel Krantz I'm investing in west haven for several reasons my area is close to university of new haven so I can rent to students, taxes are not too high like new haven so you can cash flow more, you can be near the beach in a mile so that's attractive to buyers, my area is between Milford and westville (new haven) and these two are good areas.
