SBA 504 Loans for Dental Practices: Own Your Office Space

Most dentists spend their entire career paying rent on the building where their practice operates. The SBA 504 loan exists specifically to change that math.

What the SBA 504 Loan Is — and What It Isn't

The SBA 504 loan is a fixed-asset financing program. It covers commercial real estate, construction, and major long-term equipment — not goodwill, not working capital, and not practice acquisitions.

If you're buying a dental practice from a retiring dentist, you want an SBA 7(a) loan. That program covers intangibles — the patient list, the goodwill, the value that doesn't show up on a balance sheet.

If you're buying or building the physical space your practice operates in, the SBA 504 loan is the right structure.

How the SBA 504 Structure Works

Every SBA 504 deal follows the same financing split:

• 50% — conventional first mortgage from a bank or credit union

• 40% — CDC/SBA debenture (fixed rate, long-term)

• 10% — your down payment

On a $1.5 million dental office purchase, that breaks down to: $750,000 from the bank, $600,000 from the CDC/SBA, and $150,000 from the dentist.

The CDC debenture carries a fixed rate set monthly through NADCO. As of May 2026, the rates are 5.88% (10-year), 6.01% (20-year), and 5.95% (25-year) — fixed for the life of the loan, not variable, not tied to Prime.

The bank portion carries a conventional rate negotiated separately. Monthly payment math will vary by deal size and the bank's terms on the first position.

Why Dental Practices Work Well for SBA 504

Lenders like dental practices as 504 borrowers for reasons beyond the numbers.

Dental revenue is stable and recurring. Patients schedule future appointments. Revenue holds through economic downturns — people still need dental care when belts tighten. That stability makes dental cash flow predictable to underwrite.

Owner-occupied real estate under the 504 program requires the borrower to occupy at least 51% of the building. A dentist running a full practice easily clears that threshold.

One scenario where the 504 loan comes up regularly: a dentist's landlord decides to sell the building. Rather than relocating or hoping a new landlord holds rent steady, the dentist buys the building instead — often finding that the monthly debt service is comparable to what they were already paying in rent.

SBA 504 vs. SBA 7(a) for Dentists: When to Use Which

This is the decision most dental borrowers get wrong.

Use the 7(a) when:

• Buying a dental practice (price includes goodwill and patient list)

• Purchasing equipment without real estate in the deal

• Covering working capital during a buildout or transition

• Acquiring both a practice and its building in a single transaction

Use the 504 when:

• Buying the commercial space your practice already occupies

• Purchasing property for a new dental office location

• Building out a new office on land you own or are acquiring

• Refinancing existing owner-occupied commercial real estate under the SBA 504 refi program

The two programs can also be structured together in certain deals — 7(a) for the practice acquisition, 504 for the real estate component. That requires coordination between lenders and careful underwriting, but it can work.

What Lenders Actually Underwrite

The bank handling the 50% conventional piece runs its own underwriting separate from the SBA process. For a dental borrower, they're looking at three things:

Cash flow. Does the practice generate enough to service both the bank note and the CDC debenture, with margin remaining? Lenders typically want a debt service coverage ratio (DSCR) of 1.25x or better. A practice with $600,000 in collections and $150,000 in annual debt service is in workable territory.

Practice stability. Three years of tax returns showing consistent or growing revenue. A single difficult year with a clear explanation is manageable. Declining revenue without a clear turnaround story is not.

Property fit. For an existing building, an appraisal is required. For ground-up construction, lenders evaluate location, zoning, and projected stabilized value. A specialty practice — oral surgery, implants, pediatric — with custom-built infrastructure tends to score well here because the space has limited use outside dentistry, which cuts relocation risk.

The Timeline

SBA 504 deals typically close in 45 to 90 days from signed purchase agreement. Ground-up construction projects take longer — 90 to 120 days is realistic once you account for permits and draw schedules.

The dual-lender structure (bank plus CDC) means two approval tracks running in parallel. A broker who works regularly with 504 dental deals knows which lenders move fast and how to structure the package so both sides close on the same schedule.

Bottom Line

The SBA 504 loan is one of the most efficient financing structures available for dental practice owners who want to stop paying rent and start building equity in their real estate. Fixed rates, 25-year terms, and a 10% down requirement make the monthly math work for most practices with stable production.

If you're looking at buying your office building or building a new location, the right time to model the financing is before you've signed a purchase agreement — not after.
