What is the difference between a home built on site and a factory-built home?

The single biggest difference between a factory-built home and one built on-site is the building location � one is built on site and the other is built at an off-site building center with all of the advantages that goes with that. Both are built to the same building code with the same materials. A site-built home as no financing advantage, no appraisal advantage and no appreciation advantage over a custom factory-built home. Our homes have 10-year structural warranty at no additional cost, something very few site-built homes even offer. A factory-built home is over-built so that it can be transported to the site and set on the foundation with a crane.
