Kate - there has actually only been one sale over the last few months (current market conditions) in a 3BR 2.5 BA home on over 2 acres in Newtown. It sold for $395,000. If I remove the bathroom "requirement", there have been 3 sales with an average sale price of $382,667. However, size, location and condition play a much bigger part of listing/sales price than number of BR's & BA's. As to currently available properties, there are only 4 in town that meet the 3BR, 2.5BA, 2+ acres - the average list price is $447,400.
Hope that helps.
