Modular homes are just like all other homes in that all are not the same. Some have cheap door handles and faucets that wear out in just a couple of years, but others are top of the line. That is true of everything in the home. Generally, you get to pick many things in a modular just like in a stick built home. Just be sure to make your choices wisely. You know how your family uses a home and you know what you priorities are.
PS. I lived in trailers and modular until I was a married lady so I've seen many of them.
