Based on region, construction costs per square foot for a new factory-built home average from 10 to 25 percent less than a comparable new site-built home. Independent appraisal studies confirm that factory-built homes can perform in value at the same rate as other housing forms in the same market. Costs of interim construction financing may be significantly reduced or eliminated as completion time may be shorter with factory-built homes. All construction materials, as well as interior finishes and appliances, are purchased in volume which translates directly into greater affordability for the homebuyer.
