To build a modular home you need to pay the modular home company for building the modules and the general contractor for his services. If you do not own property, you also need to purchase that.

There are two typical sources of these funds. The first is private funds, such as personal savings, an equity loan on another property, or the sale of personal assets. The second is obtaining a mortgage through a lending institution, like a bank or mortgage company.

There is one major difference between paying for an existing, already built home and paying for building a new home. When you buy an existing home you pay the seller in full before you take possession of the home, usually through the mortgage. When you build a home, you make periodic payments as the work is completed. This protects you and the lender should something prevent the completion of the home on the GC end. Receiving compensation as the job progresses also protects the modular home company or dealer and the general contractor should something prevent you from paying for the finished home.

When you use a lender to build a home, you obtain a "construction loan" which is a short-term loan usually four- to twelve-months' duration. The loan provides for a series of payments as work is completed. Once the local building inspector issues a certificate of occupancy and the lender agrees that the home is essentially complete, the lender pays off the construction loan and issues you a mortgage.

What is the most different regarding construction loans for modular home construction is the time line. With traditionally built, stick built homes, the construction process is very long, a year or longer in some cases. The modular construction process is much shorter, a couple of months only.
