You can't get a house below $200k around here. Well their is a 600sf "house" if you want to call it that for sale on a crummy street for $169k.
$200k-$300k will get you a small cape or maybe a ranch, usualy in need of TLC.
$300k-$400k will get you a nice raised ranch, cape, or small colonial. Some will need work, some won't depending on the street. You can also start looking at new construction in this range.
$400k-$500k will get you into something nice, a larger 2,500sf colonial, raised ranch ect.
$500k-$600k now your starting to get into homes that have some nice yards, and are in North Milford. This is a nice range to be in, you have a lot of choice.
$700k-$1m start to get much nicer, and as you get near $1m you can start looking at waterfront homes.
The average sale price range dropped to $430k this year from $440k last year; most buyers seem to be in the $400k-$600k range.
People buy here because its cheap compared to Fairfield county, and you can still commute to NY city. Buying in Trumbull, or closer say in Greenwich can cost much more. A $500k house here would cost $800k in Trumbull, and $1m or more in Greenwich. Their really isn't much you would want to live in for under $1m in that area.
