Larger lots are the norm where I am due to well and septic. If there was public water and sewer, the lots could be much smaller. As it stands, a half acre is about as small as they get.
These have city utilities. They are pretty nice. They have Hardy Board exteriors, small front porch, architectural shingles, around 1200SF or so on a single level. They were going for $125K but, they sold them all out. They are starting phase 2 now. We have about 5 developments booming right now.
