Some of the best modular home can last up to 50 years. But it all depends on the manufaturer.
Another confusing part is the term that is used to describe mobile homes. The term “Manufactured Housing” has been adapted by the mobile home industry to alleviate the stigma of mobile homes. Of course uninformed people bundle modular homes in this mix since modular homes are constructed in a manufacturing facility and are transported, but that is where the similarity if any ends.
There is no stigma for modular homes that I know of,but a lot of people are miss informed about modular construction. Most people are confusing mobile homes with modular 11 shipping container homes and there is a stigma about mobile homes and mobile home parks.
