I checked around on the 'net and Oak Creek (and American Homestar, the parent Company) seem to have good reputations, I am interested in opinions on Oak Creek and mobile homes in general (yes I know that a mobile home is not a “real” home investment-wise).
Don’t know anything about Oak Creek, but for your searches, the modern term for a mobile home, built to HUD standards and rolled to your site on its own wheels, is “manufactured” home. There are also “modular” homes, built in sections in a factory and assembled on-site to meet local and national building codes. Oak Creek apparently builds both.
