How to Finance a Dental Office Build: Loans, Down Payments, and the Monthly Nut

Financing a dental office build almost always means stacking three separate loans — construction, real estate, and equipment — and the number your banker actually cares about isn't your total project cost. It's the monthly payment increase your production has to cover, starting the month the doors open.

That distinction trips up more dentists than the interest rate does. Let's walk through the pieces.

The three loans in a build

A construction loan funds the actual build-out — typically disbursed in draws as work is completed, and typically converting to permanent financing once the space is finished and open. A real estate loan applies if you're purchasing the building or land rather than leasing — commonly structured as an SBA 504 loan, with terms running up to 25 years, which helps keep the monthly payment manageable relative to a shorter-term note. And an equipment loan covers chairs, imaging, sterilization, and technology — usually financed separately, over a shorter term (often 7 to 10 years) that roughly matches the useful life of the equipment itself.

Most de novo builds run all three simultaneously, which is exactly why the total financed amount can look intimidating even when each individual piece, on its own, is manageable.

Down payment, loan points, and construction-period interest

For financed amounts over $500,000 — which covers nearly every full build — most lenders want 10 to 20% down. SBA 7(a) structures can bring that down payment requirement lower in some cases, particularly when the real estate itself serves as strong collateral, though goodwill-heavy acquisition-style deals sometimes draw a lender overlay requiring 12.5 to 15% down instead of the program floor.

Two costs get missed in almost every first-pass budget. Loan points — the origination fee charged as a percentage of the loan amount, paid at closing, not spread across the loan term. And construction-period interest — you're paying interest on every dollar drawn from your construction loan while the building isn't yet producing revenue, which means real cash is leaving the project before a single patient sits in a chair.

The "monthly increase" — the number your banker cares about most

Here's the reframe that changes how this whole process feels: stop thinking about the total loan amount, and start thinking about the monthly increase — the difference between what you're paying now (rent, or your current loan payments) and what you'll be paying once the new debt service starts. That's the number that has to be covered by new production, and it's the number a lender is actually underwriting against when they look at your projected cash flow.

If your practice needs to generate an additional $12,000 a month in collections just to break even on the new debt service, that's a materially different conversation than if the increase is $4,000 a month — even if the total loan amount looks similar on paper because of different terms or down payments.

The debt-service math lenders run

Lenders aren't just checking whether you can technically make the payment — they're checking how much room you have above it. The standard benchmark is a debt service coverage ratio (DSCR) of 1.25 or higher, meaning your projected practice cash flow needs to generate $1.25 for every $1.00 of debt payment, not just $1.01. On top of that, most lenders want to see a cash reserve at closing — commonly $50,000 to $75,000 — that's separate from your working capital line, as a buffer specifically against the unexpected.

They'll also look at your projected new-patient flow and production per operatory as leading indicators of whether your revenue projection is realistic rather than aspirational — the same benchmarks we cover in Will Your New Dental Office Pencil Out?, because a lender is essentially asking the same feasibility question you should be asking yourself before you sign.

What to bring to the bank

A lender underwriting a construction loan wants to see your total project budget broken into the buckets we cover in the full cost breakdown pillar guide — construction, soft costs, equipment, and contingency — not a single lump-sum number. They'll want your projected P&L for the first 24 months, your personal financial statement, and — if you're financing an acquisition alongside a build-out or expansion — documentation on the existing practice's financials as well. The more your request looks like a modeled business plan and the less it looks like a back-of-envelope guess, the better terms you're likely to see, because you're demonstrating exactly the discipline a lender is trying to underwrite for in the first place.

This is also where running your numbers through the Dental Office Build Tool before your first meeting pays off — you walk in with a modeled monthly payment increase and payback period instead of asking your loan officer to tell you what you can afford.

Frequently asked questions

What loans do I need to build a dental office? Most builds require three: a construction loan for the build-out, a real estate loan if you're purchasing rather than leasing, and a separate equipment loan for chairs, imaging, and technology.

How much down payment do I need for a dental practice construction loan? Most lenders want 10 to 20% down on financed amounts over $500,000, though SBA 7(a) structures can reduce that in some cases depending on collateral and deal structure.

What is debt service coverage ratio and why does it matter? DSCR measures how much cash flow your practice generates relative to its debt payments. Lenders typically want a ratio of 1.25 or higher — $1.25 in cash flow for every $1.00 of debt payment — as a cushion against a slower-than-projected ramp-up.

What's the difference between total loan amount and monthly increase? Total loan amount is what you're borrowing. Monthly increase is the actual new cash your production has to cover each month compared to what you're paying now — and it's the number that determines whether the project is affordable in practice, not just on paper.
