Key takeaways

  • A construction-to-permanent loan finances the construction of a house and converts to a mortgage on completion.
  • Construction-to-permanent loans require only one round of closing costs. They also require a down payment.
  • With a construction-to-permanent loan, you can draw funds at specific phases of construction, up to a certain loan amount.

What is a construction-to-permanent loan?

A construction-to-permanent loan — also known as a one-time or a single-close loan — is a loan that finances a new-construction home. Once the home is built, the loan converts into a traditional mortgage, usually with a 15- or 30-year term.

A construction-to-permanent loan saves you time and money by streamlining the construction financing and the mortgage. You won’t have to pay two sets of closing costs or close on two separate loans.

How does a construction-to-permanent loan work?

Construction-to-permanent loans function in two phases: construction and post-construction. During the construction phase, the lender authorizes payments, or draws, to cover the cost of land, materials, labor, permits and other expenses. The lender works closely with an inspector to ensure the construction continues on schedule and on budget.

The construction phase typically lasts about one year, but it can vary depending on your lender, permitting, scheduling and the project’s size. During this time, you might only need to make interest payments. Once construction is completed, the loan converts into a traditional mortgage, and you’ll start repaying the mortgage principal and interest.

Construction-to-permanent vs. construction-only loans

In contrast to construction-to-permanent loans, you could choose a construction-only loan. These loans also cover costs related to land, labor, materials and permits, but they don’t convert into a mortgage once the home is complete. Instead, you’ll shop for a new mortgage and repay the construction loan, either with cash or your mortgage funds. You’ll pay two sets of closing costs.

You might choose the construction-only route if you plan to sell the home after building or if your preferred construction lender doesn’t offer a conversion option.

Construction-to-permanent loan example

Imagine you decide to build a new home. You want to purchase a parcel of land that costs $50,000, and you estimate that the house will cost $350,000 to build. In total, you would need $400,000 of financing.

Construction-to-permanent loans typically require a 20 percent down payment, which would be $80,000 in this case. To borrow $400,000 over a 30-year period with a 7 percent interest rate, your monthly principal and interest payment would be about $2,129. However, you might be able to pay only interest during the construction phase.

Construction-to-permanent loan eligibility requirements

Since there’s substantial risk involved with building a home, lenders typically have more stringent requirements for construction-to-permanent loans. Conventional construction-to-permanent loans can have fewer restrictions than government-backed loans, however. Here are the typical requirements:

  • Down payment: 20 percent
  • Credit score: 680
  • Debt-to-income (DTI) ratio: 45 percent or below
  • An estimated appraisal: An appraiser will need to determine the home’s estimated completed value.
  • Project approval: The lender needs to approve your budgets, schedule, blueprints and more.
  • Architect and contractor approval: You’ll need to hire licensed, professional builders and submit copies of their licenses, certificates and/or resumes to your lender.

Pros and cons of construction-to-permanent loans

Construction-to-permanent loans have benefits as well as drawbacks. Here are the major ones to consider.

Pros of construction-to-permanent loans

  • Only one set of closing costs: Instead of taking out a construction loan and then a mortgage, a construction-to-permanent loan combines the two, which limits your closing costs.
  • Ability to draw funds as needed: Construction-to-permanent loans pay out to builders as the project progresses.
  • Interest-only payments during construction: Many construction-to-permanent loans require only interest payments during construction. This can make budgeting easier, especially if you have rent or another mortgage to pay while your new home is being built.

Cons of construction-to-permanent loans

  • Bigger down payment than other mortgages: Conventional construction-to-permanent loans are riskier for lenders because the home that normally serves as collateral isn’t built. Because of this, you could be required to make a higher down payment.
  • Cost overruns: If the project goes over budget — and most do — the loan amount might not cover it. In this case, you’d have to pay out of pocket or get another loan to cover the additional costs.
  • Higher interest rates: Construction-to-permanent loans are generally more costly than conventional mortgages. What’s more, the interest rate on the construction portion of the loan might exceed the permanent mortgage rate later on.
  • More paperwork: Because a construction-to-permanent loan combines a construction loan with a mortgage, you’ll need more documentation than a traditional mortgage requires. That means submitting blueprints, a budget and licenses for contractors.
  • Builder must be approved: The lender you want to work with must approve your contractor, so you might not be able to work with whoever you want.
  • Time limit for building: Construction-to-mortgage loans typically allow one year to build the home, but you might be granted a six-month extension. If you need more time, the lender may require you to use a construction-only approach and then apply for a separate mortgage.

How to apply for a construction-to-permanent loan

Many lenders offer construction-to-permanent loans, but you’ll most often find them at a bank or with a lender specializing in construction financing. Applying involves more steps than applying for a standard mortgage.

Here’s what you’ll need to do to get started:

  1. Get preapproved: Like with other types of mortgages, it’s a good idea to get preapproved for a construction-to-permanent loan. Getting preapproved will tell you how much funding you can get based on factors like your credit score and DTI ratio.
  2. Find a builder and an architect: Research potential builders and architects, read up on their reputations and ask for references. Then set a budget and a timeline and finalize the home’s design.
  3. Get a lender: Consider at least three offers from different lenders, comparing their rates and their experience funding construction-to-permanent loans. Read consumer reviews of each lender as well. Once you decide on one, you’ll need to apply for the loan, submitting paperwork on income, assets, debts and more.
  4. Buy insurance: Your lender may require you to buy builder’s risk insurance or new construction insurance to cover the home while it’s being built.
