Whats wrong with a trailer home? I lived in one for several years.
Manufactured home - 50-75k
Wood Frame House (older) - 60-75k
Block House (old) - 80-90k
Block House (new) - 90-125k
You can still buy a very large house for a rather low price still around here. Some of our old Victorian homes here in town are selling for 125-160k. Land is where the real money is at around here.
They also don't build many wooden homes around here as the termite problem in Florida is absolutely horrendous. We have termites here that can make a house structuraly unsound in under 3 years.
You didn't list the trailer homes.
