Construction Loan vs. Mortgage: What's the Difference?
Editorial review: My Construction Path team ·
A construction loan pays for a home that hasn't been built yet. The lender releases money in stages as the work is done. A mortgage is long-term financing on a home that already exists. Many custom-home borrowers use both: a construction loan during the build that becomes, or is replaced by, a regular mortgage at move-in.

If you're building a custom home, you'll almost always start with a construction loan. Here's how the two compare, what lenders look at for each, and how they fit together.
What is the difference between a construction loan and a mortgage?
The biggest difference is the collateral. A mortgage lender can appraise and inspect a finished house. A construction lender is lending against plans, a builder contract and a future value.
| Construction loan | Purchase mortgage | |
|---|---|---|
| What it pays for | Building a home, and often the lot | Buying a finished home |
| How money is paid out | In stages (draws) as work is inspected | All at once at closing |
| What you pay during the loan | Usually interest on the money drawn so far | Principal and interest from the start |
| Appraisal | "As completed," based on plans and specs | Based on the existing home |
| Who the lender reviews | You, your builder, your plans and your budget | You and the home |
| What happens at the end | Converts to a mortgage, or is paid off by one | Runs until paid off or refinanced |
The VA's buyer's guide describes how a construction loan funds: "Construction loans are closed prior to the start of construction with proceeds disbursed to cover the cost to build, cost of the land, or balance owed on the land, with the remaining balance in escrow, sometimes referred to as a Loan in Process (LIP) account, or a Draw account" (VA Home Loan Buyer's Guide).
How does a construction loan work?
You close before work starts. The lender then pays your builder in draws at milestones such as the foundation, framing and rough-ins. An inspector usually confirms each stage before money goes out.
During the build, most lenders bill interest on the money drawn so far. See what you pay during construction. Federal disclosure rules treat these staged advances as one loan. Regulation Z says, "A series of advances under an agreement to extend credit up to a certain amount may be considered as one transaction" (12 CFR 1026.17(c)(6)).
How does a regular mortgage work?
A purchase mortgage funds the whole price at closing. You start repaying principal and interest on a set schedule right away. The house already exists, so the lender's review centers on you, the appraisal and the title. There's no builder review, no draw schedule and no conversion step.
How do a construction loan and a mortgage fit together?
There are two common structures:
- One-time close (construction-to-permanent). One loan, one closing. The construction phase converts to a permanent mortgage when the home is finished. HUD's handbook says its FHA version, "Construction to Permanent (CP) refers to the construction of a dwelling on land owned or being purchased by the Borrower" (HUD Handbook 4000.1).
- Two-time close. A short-term construction loan first, then a separate mortgage that pays it off. Fannie Mae's two-closing guidelines describe "two separate loan closings with two separate sets of legal documents."
Compare them in one-time close vs. two-time close construction loans. After the build, learn how the conversion to your permanent mortgage works.
Is it harder to qualify for a construction loan than a mortgage?
It's usually more involved, not necessarily harder for you. Your credit, income, debts and assets are reviewed the same way. The extra work is the project: the builder, the contract, the plans, the budget and an as-completed appraisal.
Lenders may also want a cushion for overruns and reserves for overlapping housing costs. For what lenders weigh, see what credit lenders look for and how much you can borrow for a construction loan.
How long is each loan in use?
A mortgage lasts until it's paid off or refinanced. The construction phase lasts as long as the build, within a period your lender sets. Builds take time. As of the Census Bureau's 2025 annual data, published July 1, 2026, contractor-built homes took an average of 10.5 months from start to completion (Census start-to-completion table). See the construction loan timeline.
When do you need a construction loan instead of a mortgage?
You'll likely need a construction loan if you:
- Are building a custom home on land you own or plan to buy
- Hired a builder to build to your plans rather than buying a finished spec home
- Want the lot purchase and the build financed together (see land and construction loans)
- Are acting as your own general contractor (see owner-builder construction loans)
A regular mortgage fits when the home is already built, including a new home a builder finished with its own money. If you own your land outright, see building on land you own free and clear.
Do construction loans cost more to close than mortgages?
They can include extra items, such as draw inspection fees, title updates during the build and a plan review. A two-time close also means two sets of closing costs. Every lender has to disclose costs on the same forms, so you can compare. See construction loan closing costs. For the full custom-home process, start with how to finance a custom home.
Frequently asked questions
Is a construction loan the same as a mortgage?
Not exactly. A construction loan funds the build in stages. A mortgage is long-term financing on a finished home. Many construction loans become a mortgage when the home is done.
Is it harder to get a construction loan than a mortgage?
It usually takes more paperwork, because the lender reviews your builder, plans and budget as well as your finances.
Can a construction loan turn into a mortgage?
Yes. A construction-to-permanent loan converts to a regular mortgage after the home is finished.
Do I need a construction loan to build a custom home?
Most people do, unless they pay cash or the builder finances the build and sells them the finished home.
Can I use a regular mortgage to buy land and build?
Generally not. A standard purchase mortgage is for a finished home. Land plus a build usually calls for a construction loan or a land loan first.
