Construction-to-Permanent Loans: How They Work
A construction-to-permanent loan might be the most misunderstood tool in the new construction financing toolkit. Most buyers assume financing a new home works just like buying a resale — you get approved, you close, you move in. But when you're building from the ground up, the money has to flow differently. A construction-to-permanent loan solves that problem in a way that's cleaner, more predictable, and often less expensive than the alternatives. Here's exactly how it works and how to know if you need one.
What Is a Construction-to-Permanent Loan?
A construction-to-permanent loan — sometimes called a C2P loan or a "one-time close" loan — is a single financing product that covers two distinct phases of building a home:
1. The construction phase, during which the lender funds draws to pay your builder as work progresses 2. The permanent phase, during which your loan converts to a standard mortgage once the home is complete
The key word is single. Instead of taking out a short-term construction loan and then refinancing into a mortgage when the home is done, you go through one application, one underwriting process, and one closing. The loan simply changes form once your certificate of occupancy is issued.
This is different from buying a move-in-ready spec home or a quick-move-in home a builder has already started. In those cases, standard mortgage financing applies. A construction-to-permanent loan is specifically for buyers who are contracting to build a home that doesn't exist yet — whether through a national builder on a to-be-built basis or through a custom home builder on a lot you own.
How the Money Actually Moves
During construction, you're not handed a lump sum. The lender and builder establish a draw schedule — a series of milestone-based disbursements tied to completed stages of work. Common milestones include foundation completion, framing, rough-in of mechanical systems, drywall, and final completion.
Before each draw is released, the lender typically sends an inspector to verify that the work has actually been done. This protects everyone. You're not paying for work that hasn't happened, and the builder has a clear financial incentive to stay on schedule.
During the construction phase, you generally pay interest only on the funds that have been disbursed so far — not on the full loan amount. That keeps your out-of-pocket costs manageable while your home is being built. Once construction wraps and the loan converts, you begin making full principal-and-interest payments on the permanent mortgage.
The One-Close Advantage
The alternative to a construction-to-permanent loan is a two-close approach: a standalone construction loan followed by a separate permanent mortgage. On paper, that sounds fine. In practice, it means:
- Two sets of closing costs
- Two rounds of underwriting and approval
- Rate exposure at the second closing — whatever rates are when you refinance is what you're stuck with
- Potential qualification issues if your financial situation changes between the two closings
The one-close structure eliminates all of that. You lock (or float, depending on the lender) your permanent rate at the original closing. You pay closing costs once. And there's no second approval process hanging over your head six to twelve months down the road.
For buyers building in communities like Epperson or Starkey Ranch where build times can run several months, that rate certainty can be genuinely valuable.
Who Actually Needs This Loan Type?
Not every new construction buyer needs a construction-to-permanent loan. Here's a quick breakdown:
You likely need a C2P loan if:
You probably don't need one if:
Many production builders — KB Home and Smith Douglas Homes included — have preferred lenders who handle new construction financing differently than a traditional C2P loan. They may offer their own programs with builder-funded incentives tied to using their lender. That doesn't make a C2P loan irrelevant, but it does mean you should understand all your options before you commit.
What Lenders Look For
Qualifying for a construction-to-permanent loan is similar to qualifying for a standard mortgage, with a few additional layers:
- Strong credit profile — Lenders want confidence you'll be creditworthy through a build cycle that could last several months to over a year
- Builder approval — Your lender will want to vet the builder's license, insurance, and track record
- Detailed construction contract and plans — The lender needs to know exactly what's being built and at what cost
- Appraised value of the completed home — An appraiser will use plans, specs, and comparable sales to estimate what the finished home will be worth
Down payment requirements vary by loan type. Conventional C2P loans typically require more equity than government-backed products. VA and USDA one-time close loans exist for eligible buyers and can significantly reduce upfront requirements. FHA one-time close loans are also available.

Common Misconceptions
"The builder controls the money." Not exactly. The lender controls the draws and verifies work before releasing funds. The builder requests draws; the lender approves them.
"I have to use the builder's lender." You don't — though you may need to weigh that against any builder incentives tied to their preferred lender. Always read the fine print on those incentives.
"If rates drop, I'm locked in at a bad rate." Some C2P loans allow for a one-time float-down option before the permanent conversion. Ask your lender specifically about this.

Frequently Asked Questions
What's the difference between a construction loan and a construction-to-permanent loan? A standalone construction loan is short-term financing that covers only the build phase. When construction ends, you pay it off — usually by refinancing into a permanent mortgage. A construction-to-permanent loan combines both phases into one product, saving you from a second closing and a second round of closing costs.
Can I use a construction-to-permanent loan in a planned community? Yes. If you're building a to-be-built home in a community like Connerton or Mirada and the home doesn't exist yet, a C2P loan may be appropriate. Check with a lender experienced in new construction financing to confirm the right structure for your situation.
What happens if construction costs go over budget? Cost overruns are the borrower's responsibility. Lenders fund up to the approved loan amount based on original plans and specs. If changes or unexpected costs push the project over budget, you'll need to cover the difference out of pocket. This is one reason accurate cost planning upfront matters so much.
Do I make payments during construction? Yes, but only on the funds disbursed so far, and typically interest-only. Your full principal-and-interest payment doesn't kick in until the loan converts to the permanent mortgage after your home is complete.
Is a construction-to-permanent loan harder to get than a regular mortgage? It's more involved, not necessarily harder. You're adding builder vetting and construction documentation to the standard underwriting process. Working with a lender who specializes in new construction financing makes this significantly smoother.
