A construction-to-perm loan is a single mortgage that pays for your build in stages, then converts to a permanent loan once the home is finished, with one application and one closing. For Southern California buyers building on a lot in the Antelope Valley, the Inland Empire, or an LA-area teardown, it is usually the cleanest way to avoid qualifying twice.
Here's the move: understand the phases, line up your builder and plans early, and get your numbers reviewed before you commit to a lot.
What is a construction-to-perm loan?
It is one loan with two phases. During construction, the lender releases money in draws as work is completed, and you typically pay interest only on what has been drawn. When the build is done and the home passes final inspection, the loan converts to a standard permanent mortgage.
The appeal is simple. You lock in your qualification up front and skip a second round of underwriting, a second appraisal, and a second set of closing costs. Rates and terms vary by borrower and market, so ask for a personalized review rather than relying on any number you see online.
How is it different from a two-close construction loan?
A two-close structure uses a short-term construction loan first, then a separate permanent mortgage after completion. The single-close option bundles both.
| Feature | Construction-to-perm (one close) | Two-close |
|---|---|---|
| Closings | One | Two |
| Qualification | Once, at the start | Again at conversion |
| Closing costs | Paid once | Paid twice |
| Exposure to market changes | Lower, since the permanent terms are set up front | Higher, since the permanent loan is arranged later |
| Flexibility to shop the end loan | Limited | Greater |
The tradeoff is flexibility. A two-close loan lets you shop the permanent mortgage later, but it also means you must qualify again after the build, and your finances or the market may have shifted. Many borrowers prefer certainty, which is why the single-close option is so popular.
What do lenders look at before you break ground?
Lenders underwrite both you and the project. On the borrower side, they review credit, income, assets, and debt-to-income. If that last term is new to you, our guide to debt-to-income ratio for a mortgage shows how it is calculated.
On the project side, expect to provide:
- Finished plans and specifications
- A detailed line-item construction budget
- A signed contract with a licensed, insured general contractor
- Proof the lot is owned or under contract
- Permits, or a clear path to them
Lenders also vet the builder. A contractor with a thin track record can sink an otherwise strong file. For a deeper checklist, read construction loan requirements.
How does the appraisal work on a home that doesn't exist yet?
The appraiser values the home "as completed," based on your plans, specifications, and comparable sales nearby. That value sets the ceiling on how much the lender will advance.
If the number comes in below your total project cost, you cover the gap with cash or equity in the land. This is where land you already own helps. Equity in the lot can count toward your contribution, which is one reason owners of Antelope Valley acreage often find construction financing more approachable than they expect.
How do construction draws and inspections work?
Funds are not handed over in a lump sum. Your builder submits a draw request when a phase is finished, such as foundation, framing, or rough mechanicals. The lender sends an inspector to confirm the work, then releases the funds.
In practice, this protects you. Money follows progress, so there is less risk of paying for work that was never done. Keep a cash reserve for cost overruns and change orders, because lenders will not fund extras that are not in the approved budget.
What happens when construction ends?
After final inspection and a certificate of occupancy from the local building authority, the loan converts to your permanent mortgage. You begin regular principal-and-interest payments under the terms set at the start. There is no new application and no new qualification at that point.
If construction runs long, interest-only payments continue during the build, so a realistic schedule matters. Ask your builder for a timeline you trust, then build in a cushion.
Can I use a construction-to-perm loan for a high-cost build?
Yes, in many cases. Southern California land and construction costs often push projects into jumbo territory. If yours does, review the jumbo loan limit in California and our overview of a jumbo home loan in California, since jumbo guidelines are stricter on credit, reserves, and documentation.
Different borrower profiles have different paths. Self-employed buyers can read about qualifying when you're self-employed in California. If you are on a smaller budget or wondering about government-backed options, see how FHA construction loans work.
What are the common mistakes to avoid?
- Picking the builder last. Your lender must approve the builder, so involve them early.
- Underestimating the budget. Soft costs, permits, utility connections, and site work add up fast, especially on raw lots.
- Skipping reserves. Overruns are common. Plan for them.
- Waiting to talk to a lender. Your financing shapes what you can build, so talk to a broker before you finalize plans.

Frequently asked questions
Can I use land I already own as part of my down payment?
Often, yes. Lenders can count the equity in your lot toward your required contribution, depending on how long you have owned it and its appraised value. Your broker can confirm how it applies to your file.
Do I have to qualify again when the loan converts?
No. With a single-close construction-to-perm loan, you qualify once at the start. The loan converts to the permanent mortgage after construction without a new application.
Can I act as my own general contractor?
Most lenders require a licensed, experienced builder. Owner-builder arrangements are rare and typically face tougher requirements, so ask your broker early if that is your plan.
How long does it take to close a construction-to-perm loan?
Timelines vary. Plan review, builder approval, and the "as completed" appraisal often take longer than a standard purchase, so start the conversation before your plans are final.
Can I get one for an investment property?
Some programs allow it, but guidelines differ from owner-occupied builds. For investor financing, see our DSCR loans in California page.
