I just looked, and there are three active listings for lots in that subdivision, Bayside Heights Ranchettes. They are priced at $335K, $350K and $375K.
One is pending, and the list price is $300K. However, this lot went under contract in Jan '05. It is tied up in an estate, and is expected to close at the end of Dec '05.
There are a few For Sale By Owners in that s/d, too.
There is a mobile home on Dawson St with water standing in the back yard priced at $433K.
Worth??? Good Question. On the east side of Dawson Street is Grayton Bayou, where the interior lots are 1/6th of an acre, and they are priced between $220K and $375K.
