Modular homes are not "stick built." That term refers to a home built onsite using regular construction techniques.

Modular homes are stick-built according to FHA and home building standards. Manufactured homes are not. Mortgages are as easy to get with a modular home as they are with a on-site built home. That is why they go up in value the same as on-site homes.

(In fact, one can't tell the difference since they are constructed the with the same materials and techniques

There is a difference between "stick built" which modulars are, and "site built" which is the normal 6 to 8 month construction.

After modulars are placed on the foundation, they are in every way the same as a site built home. And the final cost is pretty much the same as site built.

AND a huge advantage is that you don't have the settling and cracks in a modular home that you have in a site-built home.

We have owned many site-built and two modulars over the past 60 years and the modulars are much nicer IMHO. The only manufactured types we have owned were motor homes and 5th wheels. I do realize those tend to degrade faster than a home since they are moving a lot but they sure do degrade fast.
