Home Building questions, answered by experts

Options include traditional mortgages, construction loans, and personal loans. Consult lenders specializing in modular home financing.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

Green homes are often more expensive to build, averaging around $200 per square foot compared to the $150 per square foot you’d spend to build a standard home. However, green homes can save you money on your utility bills by consuming less energy or creating energy using solar panels or wind turbines on-site. They’re more expensive to build, but they often end up costing less in the long run.

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

Yes, you can finance new construction using a construction loan or a construction-to-permanent loan, or you can use a home equity line of credit or a cash-out refinance if you’re building a second home. Some mortgagors may have restrictions on DIY house builds, so be sure to check that you can get financing before starting your project.
