Building a Home? Here’s What You Actually Need to Know About Construction Loans
Construction loans sound complicated. They’re not simple—but they’re not mysterious either. Once you understand the moving parts, the whole thing becomes far more manageable. Here’s the clearest way to think about it, based on how we’re approaching our own build.
What a construction loan actually is
At its core, a construction loan is a short-term, interest-only loan designed to fund your home build in stages. You don’t receive all the money upfront. Instead, the bank releases funds in draws as progress is made—foundation, framing, electrical, and so on. You only pay interest on the amount that’s been drawn, not the full loan.
The two ways to structure it
There are two primary paths, and the difference matters.
One-time close (construction-to-permanent)
- You lock your interest rate upfront
- The loan automatically converts into a mortgage when the build is complete
- One closing, fewer fees
Two-time close (what we chose)
- One loan for construction
- A separate mortgage after the home is finished
- Two closings, but more flexibility with timing your interest rate
We chose the two-time close. With rates where they are, locking early didn’t make sense for us. This gives us the option to secure a better rate later.
How we’re approaching it
This is where strategy comes in. A few decisions are shaping how we’re managing the loan:
A long-term lender relationship. We’ve worked with our lender since 1999. That history carries weight. In our case, it means he’s covering almost all of our closing costs—something that helps offset the downside of having two separate closings.
Approved for more—but planning to use less. We were approved for more than we expect to need. That’s by design. It creates a buffer for unexpected costs. But the goal is simple: borrow less, not more.
We're selling our current home during the build, not waiting until after. We weren't ready to sell when we started the loan process, but we will sell before the build is complete. We'll take advantage of staying with family for a short while, which will allow us to save on typical homeowner expenses like our mortgage, interest, insurance and utitlies during those months.
Minimizing draws to reduce interest. Every dollar you draw starts accruing interest immediately.
So we’re paying for as much as we can out of pocket – especially after we sell our current home – during the build. Fewer draws means:
- Lower interest payments during construction
- Less total cost over time
The trade-offs
There’s no perfect structure—only trade-offs.
- Two closings mean more coordination and paperwork
- Interest rates could rise instead of fall
- Using cash during the build reduces liquidity
For us, the flexibility and potential savings outweigh the downsides.
The takeaway
Strip it down, and a construction loan comes down to four decisions:
- Do you have a lender you know or that comes highly referred?
- When do you lock your interest rate?
- How much do you actually borrow?
- How long is the bank’s money in play?
Get those right, and everything else becomes detail.
We’re learning as we go and sharing what’s working for us. This isn’t a universal playbook—just a real-world approach that’s helping us make smarter decisions during the build.
