A construction loan only funds the build. At some point, that debt needs to either get paid off — through a sale or a separate refinance — or convert into permanent financing. How and when that conversion happens is decided at the very start, when you choose between a one-time close and a two-time close structure. The choice affects your closing costs, your rate risk, and how much flexibility you have if the project doesn't go exactly as planned.
One-Time Close: Construction and Permanent Financing in a Single Closing
A one-time close (also called a single-close or construction-to-permanent loan) combines your construction financing and your permanent loan into one closing, before you break ground. The loan automatically converts to permanent financing once the build is complete and inspected, without a second closing.
Because you qualify for the permanent loan upfront, the rate and terms of that permanent financing are typically locked in before construction even starts. That protects you from a rate increase during the build — valuable in a rising-rate environment — but it also means you're committed to those terms even if better financing becomes available by the time the home is finished, and even if construction costs change meaningfully from your original budget.
Two-Time Close: Two Separate Loans, Two Separate Closings
A two-time close keeps the construction loan and the permanent loan entirely separate. You close on a short-term, interest-only construction loan first, draw against it as the build progresses, and then — once the home is complete — close again on a new permanent loan (or a DSCR loan, if the property is going to be a rental) that pays off the construction debt.
Comparing the Two Structures
| Closing costs | One-time close: one set of closing costs | Two-time close: two full sets of closing costs, one per loan |
|---|---|
| Rate risk during construction | One-time close: permanent rate locked upfront, insulated from rate moves during the build | Two-time close: permanent rate isn't set until the second closing, exposed to rate movement over the build timeline |
| Flexibility on permanent terms | One-time close: locked in early, harder to change if your plans shift | Two-time close: free to shop the permanent loan (including a DSCR loan) once the property is complete and has real numbers |
| Best fit | One-time close: an owner-occupant build with a clear plan to keep the home | Two-time close: an investor who may sell, rent, or decide the long-term financing once the property is finished |
Why Most Investor-Builders Lean Toward Two-Time Close
- You don't have to decide your long-term plan — sell or hold as a rental — until the property actually exists and you can run real numbers against it
- If you plan to hold as a rental, a two-time close lets you shop a DSCR loan against the property's actual rent, rather than committing to permanent terms before you know what the home will rent for
- You're not locked into a permanent rate quoted before construction even started, which can be a meaningful advantage or disadvantage depending on which way rates move during your build
- A construction-only loan is typically simpler to underwrite and close quickly, which matters when timing a land purchase or getting a build started
Why a One-Time Close Can Still Make Sense
- You already know you're keeping the finished property long-term and want rate certainty locked in before you start, rather than taking on rate risk during the build
- You'd rather handle one closing and one set of closing costs than two, even at the cost of some flexibility
- Your lender offers a construction-to-permanent product with investor-friendly terms, which makes the simplicity worth the tradeoff
The Bottom Line
There's no universally better structure — it depends on how certain you are about your long-term plan for the property and how you want to manage rate risk during the build. An investor who may pivot between selling and holding as a rental usually benefits from the flexibility of a two-time close, while a borrower with a fixed long-term plan may prefer the simplicity and rate certainty of locking everything in with a one-time close before breaking ground.
