Know which loan fits your project before you keep reading
Try the Construction Loan Calculator →Are you building a house from the ground up, or are you standing in your own kitchen thinking "I just need one more room"? Those are two very different projects — and they usually call for two very different loans. Let's walk through both, so you know exactly which door to walk through.
If you're starting from an empty lot — no existing house, nothing standing yet — a construction loan is the right tool. Here's why, and what it actually takes to get one.
A construction loan isn't like a regular mortgage, and the difference comes down to one simple fact: the house doesn't exist yet. A traditional lender can appraise a home that's already standing. With new construction, all they have is a set of blueprints, a budget, and your word that the contractor will finish on time. That's a bigger risk for them — which is exactly why they ask more of you.
Here's what most lenders want to see before they'll approve a construction loan:
Rates on the construction phase itself typically run 7–9%, which is 1–2 points higher than a standard mortgage. That's the price of financing something that doesn't exist yet.
| Type | How It Works | The Tradeoff |
|---|---|---|
| Construction-to-permanent | One loan starts as construction financing, then automatically converts to a regular mortgage when the home is finished | Usually the better deal — one closing means lower total fees |
| Construction-only (stand-alone) | Covers just the build phase; you refinance separately into a permanent mortgage afterward | Two closings, and you carry the risk that your financial picture or rates change before you refinance |
| Renovation loan | For substantially improving a home you already own, rather than building new | Different qualifying rules — often overlaps with what a HELOC can also do |
The one-time-close, construction-to-permanent option is usually worth it — it typically saves $3,000–$6,000 in closing costs compared to closing twice.
One more thing worth knowing: the core idea of a construction loan is the same everywhere, but the fine print — maturity limits, disbursement rules, licensing — can vary by state and by lender. The numbers above are national norms; always confirm the specifics with lenders in the state where you're building.
If you already have a house, a mortgage, and equity built up, a construction loan is usually the wrong tool. What you actually want is a way to borrow against the home you already own — that's exactly what a home equity line of credit (HELOC) is built for.
Think of a HELOC less like a loan and more like a credit card secured by your house. You get approved for a credit limit based on your equity, and you draw from it as your project needs money — pay the framer when the framing's done, pay the electrician when the wiring's in — instead of receiving one lump sum on day one and paying interest on all of it before you've spent a dime of it.
What do you need to qualify for a HELOC?
Most HELOCs give you a 5–10 year draw period where you only pay interest on what you've actually borrowed, followed by a repayment period where you pay down both principal and interest. And here's a detail worth knowing: if the money genuinely goes toward building, buying, or substantially improving the home securing the loan, the interest may still be tax-deductible under current IRS rules — worth confirming with a CPA for your specific situation, since the deduction has limits tied to your total mortgage debt.
| Question | Construction Loan | HELOC |
|---|---|---|
| Best for | Building a home from the ground up | Adding onto or renovating a home you already own |
| How you get the money | Draws released by the lender as milestones are inspected | You draw whenever you need it, like a credit card |
| Typical rate (2026) | 7–9% during construction | Variable, often tied to Prime + a margin |
| Down payment / equity needed | 20–25% down | 15–20% equity remaining after the HELOC |
| What happens after | Converts to a permanent mortgage, or you refinance | Repayment period begins — no conversion needed |
Ask yourself one question: does the house you want already exist? If you're buying land and starting from an empty lot, you need a construction loan — there's no equity yet to borrow against. If you're standing inside a house you already own and just want more of it, a HELOC almost always makes more sense: no builder-approval process for the lender, no draw-schedule bureaucracy for a full new build, and you keep your original mortgage's rate untouched.
Ready to run the numbers on your own build?

If you're buying a new-construction home from a builder like Lennar or KB Home, the builder typically finances construction themselves, and you just apply for a standard mortgage on the finished home. Construction loans are mainly for custom or semi-custom builds where you're hiring your own contractor.
Not usually for the same project — but some homeowners use a HELOC on their current home to cover the down payment on a construction loan for a new build. It's a real strategy, but it means carrying two forms of debt at once, so run the full numbers before committing.
Some lenders offer renovation-specific HELOCs that lend against your home's after-renovation value instead of its current value — which can unlock more borrowing power for a bigger addition. It's a more specialized product, so ask specifically for it by name when you shop lenders.
Your home secures the debt either way, so yes — falling behind on a HELOC carries the same foreclosure risk as falling behind on your mortgage. The added wrinkle with a HELOC is the variable rate: your payment can move up over time. If predictability matters more to you than flexibility, a fixed-rate home equity loan is worth comparing too.
The builder provides it, but you should still ask to see it yourself before you commit. The lender is approving the builder on the bank's behalf — it's still your project, your money, and your name on the loan.
