In my short experience, there is a very practical difference between "manufactured" and "modular" which is explained at the Ideabox site link below. We have seen/stayed in one of these Ideabox homes and they seem a good balance for a house when you're not a "I want to build my dream castle" kind of person (that's me). https://www.ideabox.us/
Ideabox's cheapest home is a 780 sq ft 1BR for $230K. According to their cost estimate, the total cost would be $420k. This seems over-priced. Pre-fab homes should be cheaper than custom-built homes. A new home of that size will not cost $400k in Wyoming or Kansas.
Yeah that's my main pick with all pre-fab proposals that eventually pop-up here and there, some of them even winning awards for "affordable" housing. Every. single. time. the total cost of the project is on the 6-7 figures range ...
