My guess, based not on its condition or whatever amenities it has, is around $68 to $92 per square foot with an average of $80 per square foot. This is rough guidance only and the particulars of the property have to be taken into account to arrive at a good estimate of value.
Sold prices range from $225 to $265k with an average of $245k.
Current prices range from $220 to $280 with an average of $250
