That stated, it's only as good as the person/s putting it together. You may also want to consider a "Factory Built" (Manufactured (HUD) or Modular home depending on the location and the relative CC&Rs. In this situation you are purchasing a home that is completly built before it leaves the factory.
You can do just about anything you want to do with Factory Built Housing nowadays i.e. stucco ready, tile roof ready, curvalinear architectural detailing i.e. pop out & inset features, upgraded kitchens, bathrooms, floor, window, wall coverings, appliances, etc.
The turn around time is a lot faster and you have no excess or wasted materials and you don't have to worry about vandalism, theft or weather conditions. All in all it's a very practical and cost effective way to build a home today and many banks will offer conventional FHA, Fanny/Freddie.
I don't know where you are planning to build but most if not all Counties and Cities are FBH friendly. The most important aspect of the entire procedure be it "Factory Built" or "Prefab" is hiring an experienced, licensed, bonded and insured contractor. I definitely don't reccomend trying to take on a project like this as an owner/builder. You may find it very difficult to find construction or take out financing.
We are a family owned and operated Factory Built Housing Dealer & Developer, general and manufactured home contractor, real estate broker, architectural, engineering, landscaping and interior design company with over 100 years of combined experience.
We may not be in your geographical area as we work primarily in the Orange County, San Diego and Palm Springs/Palm Desert area. But we will be more than happy to coach you and direct you to a competent, experienced and properly licensed and insured MH Dealer and Contractor at no cost as long as it can be done online or by phone.
