House Building Financing Options
If you have the funds to finance your dream house, you are welcome to skip this section. If not, then do not lose hope. Prepare a budget and get an estimate of how much money you need, then apply for one of the following home loans:
Home Construction Loan
The two most prominent home construction loans are as follows:
- Construction-to-Permanent Loan: This loan covers both land purchasing as well home building costs. Once the construction is complete and you move into the house, the loan is converted to a conventional mortgage of 15 to 30 years.
- Construction-only Loan: It is meant only for financing the home building, and does not cover the land purchase. After your home is ready, the entire loan amount is due. You either cover the amount by paying cash or taking out a mortgage.
Personal Loan
A personal loan will not cover your entire home-building cost. Take out a personal loan to finance a specific part of the construction. Say, you forgot to account for landscaping while budgeting your home-building finances. In such a case, a personal loan can come to your rescue.
Home Equity Loan
Home equity loan applies to homeowners who already have a property and want to finance the construction of a new one. 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.
