A dentist I spoke with last year had built a thriving practice inside a leased suite for eight years, paying down someone else’s mortgage the whole time. When her landlord put the building up for sale, she had 60 days to either buy it or start over somewhere new. That’s the scenario an SBA loan for a dental office is built for: financing the real estate a dental practice sits in, often alongside the practice acquisition itself, without draining the cash a growing practice needs to operate.
If you’re a dentist buying your building, buying out a retiring dentist’s practice and real estate together, or building a new office from the ground up, SBA 7(a) and SBA 504 loans are the two programs that make it possible with a fraction of the down payment a conventional commercial mortgage would require.

What Is an SBA Loan for a Dental Office?
An SBA loan for a dental office is a commercial real estate loan, guaranteed in part by the U.S. Small Business Administration, used to purchase, construct, or renovate the building a dental practice occupies. The two programs dentists use most are the SBA 7(a) loan and the SBA 504 loan. Both require the practice to occupy at least 51% of an existing building, or 60% of a newly constructed one. That’s the SBA’s owner-occupancy rule, and it exists to keep these programs focused on small businesses using the space they finance rather than investors.
Dental real estate is a good fit for both programs because the collateral (a specialized medical/dental buildout with plumbing, electrical, and equipment infrastructure already in place) tends to hold value, and the borrower’s income (practice collections) is usually well-documented and stable.
SBA 7(a) vs. SBA 504 for Dental Practice Real Estate
These two programs solve overlapping but different problems. Here’s how they compare for a typical dental real estate purchase:
| Feature | SBA 7(a) | SBA 504 |
|---|---|---|
| Maximum loan amount | $5 million | $5.5 million (504 portion) |
| Typical down payment | 10-15% | 10% (15% for a new/special-use property like a dental office) |
| Rate structure | Variable, tied to prime | Fixed on the 504 debenture portion |
| Real estate term | Up to 25 years | 10, 20, or 25 years |
| Can finance practice acquisition + real estate together | Yes, in one loan | No. 504 is real estate/equipment only; practice acquisition needs a separate 7(a) or conventional loan |
| Best for | Combined practice + real estate purchase, or when you want one lender and one closing | Real-estate-only purchases where you want the lowest long-term fixed rate |
Here’s what doesn’t get talked about enough: most dentists don’t actually choose 7(a) or 504 based on rate. They choose based on whether they’re buying just the building, or the building and the practice together. If it’s both, 7(a) is usually the cleaner path: one loan, one closing, one lender to manage. If it’s real estate only and you already own the practice, 504 usually wins on long-term fixed pricing. We cover this comparison in more depth in our SBA 504 vs. SBA 7(a) breakdown.
How Much Down Payment Do You Need?
For a straightforward real estate purchase, SBA 504 typically requires 10% down. That jumps to 15% if the property is considered “special use,” and dental offices, with their plumbing lines, vacuum systems, and treatment room buildouts, often get classified that way by SBA lenders. If you’re a startup practice (less than two years in business), add another 5%, for 15-20% total.
SBA 7(a) down payments run similarly, generally 10-15% depending on whether you’re financing real estate alone or bundling in a practice acquisition, working capital, or equipment. Either way, you’re putting down a fraction of what a conventional bank would ask for on medical-use real estate, where 25-35% down is common.

Buying the Practice and the Building at the Same Time
This is where dental deals get more complicated than a typical owner-occupied commercial purchase, and where a lender’s SBA experience actually matters. Most retiring dentists sell the practice and the real estate together, which means you’re underwriting two assets in one transaction: the goodwill and patient base of the practice, and the building it sits in.
I recently worked through this exact structure with a dentist buying out a retiring practitioner’s office in the Southeast. The practice itself supported roughly $900,000 in annual collections, and the seller owned the building outright. We structured it as a single SBA 7(a) loan covering the real estate, the practice purchase price, and a working capital reserve for the transition: one closing, 10% down from the buyer, 25-year amortization on the real estate portion blended with a 10-year term on the practice debt. That blended structure is standard for combined deals and it’s the main reason 7(a) tends to be the better fit when the real estate and the practice are changing hands together.
Lenders will want to see the seller’s practice financials (usually 2-3 years of collections and a profit-and-loss statement), a valuation of the practice itself, and, separately, an appraisal on the real estate. Expect the underwriting timeline to run longer than a real-estate-only deal, generally 60-90 days from application to close.
Building a New Dental Office vs. Buying an Existing One
Ground-up construction changes the occupancy math and the draw process, but the loan programs are the same. For new construction, the SBA’s occupancy requirement rises to 60% (versus 51% for an existing building), since the SBA assumes a growing practice will eventually fill out the space it built.
Construction financing through SBA 504 or 7(a) funds in draws tied to completion milestones, similar to any ground-up construction loan, and typically converts to permanent financing once the certificate of occupancy is issued. Budget for dental-specific buildout costs to run considerably higher per square foot than a standard medical office. Plumbing for multiple operatories, compressed air and vacuum systems, and x-ray shielding all add cost that a generic commercial construction estimate won’t capture. Get your general contractor’s dental-specific experience documented early; SBA lenders will ask for it.
What Rates Look Like Right Now
SBA 7(a) rates float over the prime rate, which sits at 7.00% as of late September 2026, according to Federal Reserve data. Real estate-secured 7(a) loans over $50,000 with terms of at least seven years are typically capped at prime plus 2.75%, putting most dental real estate deals somewhere in the 9.5-10.5% range depending on loan size and the lender’s spread.
SBA 504 pricing works differently. The bank-financed first mortgage portion (roughly 50% of the deal) floats with the market, while the SBA-guaranteed second mortgage (up to 40%) is fixed for the life of the loan, pegged to an increment over 10-year Treasury yields. That fixed piece is the main reason practices that don’t need working capital or practice-acquisition financing often prefer 504.
Neither program is cheap money. This is still small business lending, not agency multifamily debt, but the 10% down payment and long amortization are what make monthly payments manageable for a practice that’s carrying equipment leases and, often, student loan debt on top of the real estate.
Frequently Asked Questions
Can a dentist use an SBA loan to buy an existing practice and its building together?
Yes. This is one of the most common uses of the SBA 7(a) program among dental borrowers: it can finance the real estate, the practice purchase price, and a working capital reserve in a single loan.
How much down payment is required for an SBA loan on a dental office?
Generally 10% for an established practice buying existing real estate, rising to 15% for special-use buildings (which most dental offices qualify as) and up to 20% for startup practices under two years old.
What credit score do you need for an SBA loan for a dental practice?
Most SBA lenders look for a minimum personal credit score in the mid-600s for the guarantor, though a stronger score helps with pricing and can offset a thinner down payment on a case-by-case basis.
Can you use an SBA loan to build a new dental office from the ground up?
Yes. Both SBA 7(a) and SBA 504 finance ground-up construction, funded in draws tied to completion milestones, with the SBA’s owner-occupancy requirement rising to 60% for new construction versus 51% for an existing building.
Is SBA 7(a) or SBA 504 better for a dental practice?
It depends on what you’re financing. If you’re buying the practice and the building together, 7(a) is usually simpler: one loan, one closing. If it’s a real-estate-only purchase, 504 usually offers the better long-term fixed rate on the largest piece of the loan.
