I have checked my sales in 1999, Of the homes that I sold in Plainview in 1999 two of them were capes and both had 4 Bedrooms. I don't know the Sq ft for your home but with the extensions it could be close to the sq ft of a 4 bedrooms cape. Of course condition, location, property size, number of baths and having a basement also matters. The 2 capes I sold in Plainview in 1999 were at 5 Lester Pl, sold for $213,000 and 17 Cedar dr E. sold for $252,000. If you want additional information feel free to contact me.
