Commercial construction loans: ground-up financing for builders

Quick answer

A commercial construction loan funds the building of income-producing or for-sale property — apartments, retail, office, or spec development. Funds release in draws as the project hits milestones, and you pay interest only on what you've drawn.

Most lenders finance 70–85% of total project cost, so plan for 15–30% equity. The loan is short-term; you repay it by selling or refinancing into permanent financing when the build is done.

A commercial construction loan is a different animal from a regular business loan. Lenders aren't really underwriting you. They're underwriting the project.

The budget, the timeline, the general contractor, and the exit all matter as much as your credit. Get those right and the financing follows. Get them wrong and no rate in the world saves the deal.

Here's how these loans actually work, what they cost, and what lenders need to see before they fund a ground-up build.

Key takeaways

  • Funds release in draws as the build hits milestones — you pay interest only on what's drawn.
  • Loan-to-cost usually runs 70–85%, so you bring 15–30% equity in cash or land value.
  • Lenders underwrite the project: budget, timeline, your experience, and the exit.
  • It's short-term — repay by selling or refinancing into permanent financing at completion.

What is a commercial construction loan?

A commercial construction loan finances building property meant to produce income or be sold. Think apartment complexes, retail centers, offices, or spec homes built for resale.

It's not the same as a mortgage on a finished building. You're borrowing to create the asset, which is riskier for the lender, so the structure and pricing are different.

The borrower is usually a developer, builder, or investor with a plan to complete the project and then either sell it or hold it with long-term financing.

How commercial construction loans work

The lender commits to a total amount, then releases it in pieces called draws as the project progresses.

You don't get the money up front. Complete the foundation, the lender inspects it, and the first draw releases. Same for framing, mechanicals, and finishes. The process protects the lender from funding a building that never gets finished.

During construction you pay interest only on the amount drawn so far, which keeps carrying costs manageable while you build. Our guide to how draw schedules work covers the mechanics in detail.

Types of commercial construction loans

Ground-up construction finances a project from raw land through completion. The lender funds a percentage of total cost and releases draws as the build progresses.

Multifamily and apartment construction is among the most fundable, thanks to strong rental demand. Lenders scrutinize your rent-roll projections and your path to permanent agency financing.

Land development is earlier-stage — acquiring and improving land with grading, utilities, and roads before vertical construction. It's riskier, so terms are tighter and experience matters more.

If your model is buying and rehabbing rather than building new, compare these against fix and flip loans, which fund purchase plus renovation.

Loan-to-cost and how much you can borrow

The number that sizes your loan is loan-to-cost, or LTC.

Most lenders fund 70 to 85% of total project cost. At 80% LTC on a $1 million project, the lender puts in $800,000 and you bring $200,000.

Your equity can come from cash or from the value of land you already own. Land you bought years ago at a good price can cover a big chunk of your required equity, which is one reason developers hold land.

Rates and terms

Commercial construction loan rates run higher than permanent mortgages because building carries more risk. They're often floating — a benchmark rate plus a spread — rather than fixed.

The construction phase usually lasts 12 to 24 months. That's deliberately short, because the loan is meant to get you to completion and then convert or pay off.

Strong sponsors with experience and real equity in the deal get the best pricing. Thin equity or no track record means a higher rate, lower leverage, or both.

What lenders look at

Four things carry the decision. The project budget, the timeline, your experience as a sponsor, and the exit.

A detailed, realistic budget signals you know the job. A padded or vague one signals the opposite, and lenders have seen plenty of both.

Your general contractor matters too. A first-time developer with a proven GC is far more fundable than an experienced one paired with an unknown builder. For the company side of your operation, a construction business loan can fund overhead while project loans fund the builds.

The exit: how you repay

Every commercial construction loan needs an exit, and lenders evaluate it before they fund a dollar.

You either sell the completed property and repay from the proceeds, or you refinance into permanent long-term financing and hold the asset. For owner-occupied projects, an SBA 504 loan can be a strong permanent-financing exit.

One real-world wrinkle. If your permanent financing is approved but delayed, or a draw lags, a short-term bridge keeps the project moving. eBoost Partners offers bridge construction financing for exactly that gap between phases.

How to apply

Lead with the project package. Lenders want the budget, the timeline, the site, your GC's credentials, and your pro forma with realistic projections.

Show your equity clearly — cash, land value, or both — and your exit plan in writing. A clean package moves faster and earns better terms.

Then compare offers on leverage and structure, not just the headline rate, since LTC and draw terms change your real return more than a quarter-point on the rate. If cash flow gets tight between draws, a line of credit bridges the gap. You can also compare project-friendly lenders through eBoost's construction business financing on a single application.

When your package is ready, pre-qualify with a soft credit pull — no impact to your score.

Frequently Asked Questions

How much do I need to put down on a commercial construction loan?

Most lenders fund 70–85% of total project cost (loan-to-cost), so plan for 15–30% equity. That equity can be cash, the value of land you already own, or a mix of both.

What is loan-to-cost (LTC)?

Loan-to-cost is the percentage of total project cost the lender will finance. At 80% LTC on a $1M project, the lender funds $800,000 and you bring $200,000. LTC is the main number that sizes a commercial construction loan.

Do I need construction experience to qualify?

It helps a lot. First-time developers can still get funded with a strong general contractor, a detailed budget, and meaningful equity in the deal, but experienced sponsors get better terms and higher leverage.

How are commercial construction loans paid out?

In draws — funds release in stages as the project hits milestones like foundation, framing, and finishes, with an inspection before each release. You pay interest only on what's been drawn.

What happens when construction is finished?

You repay the construction loan through your exit: either selling the completed property or refinancing into permanent (long-term) financing. Lenders evaluate that exit before they fund the project.

What are commercial construction loan rates?

Rates run higher than permanent mortgages because of build risk and are often floating — a benchmark rate plus a spread. Experienced sponsors with strong equity get the best pricing.

How long does a commercial construction loan last?

The construction phase typically runs 12 to 24 months. After completion you move into permanent financing or sell, so the construction loan itself is short-term by design.
