House Building Financing Options

Here are the typical home-building financing options available for you:

Home Construction Loans

The two most prominent home construction loans are:

  • Construction-only Loan: It only covers the cost of home building. After your home is ready, the entire loan amount is due. You can pay back the loan in cash or take out a mortgage.

Personal Loan

A personal loan will not cover your entire home-building cost. You can opt for a personal loan to finance a specific part of the construction. For example, you can finance landscaping through a personal loan.

A home equity loan applies to homeowners who already have a property and want to finance new construction. Depending on how much equity you own in your existing home, you can finance the entire construction of your new home or a part of it.
