Best option to build a low cost home on lot in Riviera Beach?

[Glenn Kopensky]

I have a lot in Riviera Beach which I could build a house on for rental. Problem is the houses in the area sell for $80k to $120k mostly. I am seeing online to figure $90+ per sq ft to build a basic no frills house. That's $144,000 for a 1,600 sq ft house plus I would have to run utilities and sewer. The best type of construction here is CBS because of termites and possible wind. Does anyone know of another option to get a house on the lot for under $100k ?
