Dental Practice Real Estate: Sell, Retain and Lease, or Separate the Building Guide
A dentist who owns the practice building should value the real estate separately from the dental business, then compare after-tax sale proceeds with the risk-adjusted value of future rent. The lease must work for both the seller-landlord and the practice buyer.
Should a dentist sell or retain the building when selling the practice?
Sell the building when immediate liquidity, diversification and a clean exit outweigh future rental income and appreciation. Retain the building when market rent produces acceptable cash flow, the buyer is a strong tenant and the seller accepts landlord, vacancy and concentration risk.
Do not decide from gross rent or gross sale price. Compare after-tax cash by year, debt payoff, transaction costs, capital needs, property-tax changes and a realistic terminal value.
As of August 24, 2026
The building and dental practice are separate economic assets.
- Use separate valuations for real estate and the operating practice.
- Model market rent in the buyer's normalized cash flow.
- Test sale, retained-lease and later-sale scenarios after tax.
- Review California reassessment and federal disposition rules.
What are the main dental-practice real estate options?
| Option | Seller benefit | Seller risk | Buyer issue |
|---|---|---|---|
| Sell building with practice | Immediate liquidity and clean exit | Current tax and loss of future appreciation | Larger financing need |
| Retain and lease to buyer | Rental income and retained asset | Tenant, vacancy, repair and concentration risk | Long-term occupancy cost |
| Lease with later purchase option | Rent now and possible later liquidity | Future price and financing uncertainty | Option terms and capital planning |
| Sell building to third party | Liquidity without requiring buyer ownership | Closing coordination and lease assignment | New landlord and lease terms |
Illustration—not an appraisal
How can a seller compare a building sale with retained rent?
| Illustrative building economics | Sell now | Retain and lease |
|---|---|---|
| Market value | $1,500,000 | $1,500,000 retained asset |
| Mortgage payoff | ($500,000) | $500,000 debt remains |
| Annual base rent | — | $120,000 |
| Annual owner costs | — | ($25,000) |
| Annual debt service | — | ($55,000) |
| Pre-tax cash flow | Net sale proceeds | $40,000 per year |
The retained option does not produce an 8% cash yield merely because $120,000 of rent equals 8% of value. In this example, owner costs and debt service reduce annual pre-tax cash flow to $40,000. A complete comparison adds tax, principal amortization, capital expenditures, vacancy and future sale value.
Which lease terms affect dental-practice value and financing?
| Lease term | What to define | Transaction effect |
|---|---|---|
| Premises and permitted use | Suite, parking, signage and dental use | Confirms the buyer can operate |
| Initial term and options | Length, renewal notice and option rent | Supports lender and buyer occupancy horizon |
| Base rent and escalations | Market support and increase formula | Changes normalized practice cash flow |
| Operating expenses | Taxes, insurance, CAM and reconciliations | Determines total occupancy cost |
| Repairs and replacement | HVAC, roof, plumbing and dental systems | Allocates capital risk |
| Improvements | Ownership, removal and restoration | Affects buyer investment and landlord value |
| Assignment and change of control | Lender rights and future practice sale | Can restrict buyer financing or resale |
| Default and remedies | Cure, acceleration and lease termination | Links real estate to practice continuity |
How should market rent be established?
Use an independent commercial appraisal or broker analysis with comparable dental or medical space, location, condition, tenant improvements, lease term and expense structure. Market rent should be tested against the buyer's normalized practice cash flow and lender underwriting.
| Rent input | Evidence |
|---|---|
| Usable and rentable square feet | Lease plan or measurement |
| Comparable rent | Recent comparable leases |
| Expense structure | Gross, modified gross or triple-net terms |
| Tenant improvements | Dental buildout age and replacement needs |
| Escalations | Fixed, indexed or market reset |
| Term and credit | Lease duration and buyer financial strength |
Above-market rent can depress practice value and debt-service capacity. Below-market rent can transfer value from the landlord to the practice buyer. Separate appraisals help prevent either asset from subsidizing the other without disclosure.
What taxes should be modeled if the dental building is sold?
| Tax item | Review question |
|---|---|
| Adjusted basis | What are original cost, improvements, depreciation and other adjustments? |
| Federal gain character | How do §1231, depreciation and unrecaptured §1250 rules apply? |
| California income tax | What state tax applies to the recognized gain? |
| Debt payoff | How does liability relief affect amount realized and cash? |
| Transaction costs | Which selling costs reduce amount realized? |
| Estimated taxes | When are federal and California payments due? |
The real estate sale should be modeled separately from the dental-practice asset sale. The building, land, improvements, equipment and goodwill can have different basis and tax character.
Can a dentist use a §1031 exchange for the building?
A qualifying §1031 exchange may defer gain when real property held for productive business use or investment is exchanged for like-kind real property that will also be held for business or investment and all timing and procedural requirements are met. Since 2018, §1031 applies only to real property, not dental equipment, goodwill or other practice assets.
Exchange planning must begin before the sale closes and before the seller receives or controls proceeds. A qualified intermediary and transaction-specific tax and legal advisers should be involved before documents are finalized.
How can California property-tax reassessment affect the decision?
A California change in ownership generally causes the county assessor to reassess the transferred real-property interest to current fair market value unless an exclusion applies. A higher assessed value can increase the buyer's property tax and total occupancy cost. Entity-interest transfers and leases with long remaining terms or renewal options can also require specialized review.
| California event | Review |
|---|---|
| Direct building sale | Expected reassessed value and supplemental assessment |
| Partial ownership transfer | Percentage transferred and applicable exclusions |
| Legal-entity ownership change | Change-in-control and cumulative transfer rules |
| Long-term lease | Remaining term including renewal options |
| Practice-only sale | Confirm no unintended real-property ownership change |
What risks remain when the seller keeps the building?
- One dental tenant may represent most or all property income.
- Specialized dental improvements can increase downtime and re-leasing cost.
- The seller remains exposed to repairs, insurance, taxes and environmental issues.
- A practice default can reduce both rent and the value of deferred sale consideration.
- Future sale value depends on lease terms, tenant credit and capital-market conditions.
- Estate and succession plans must address the building separately from the practice sale.

Frequently asked questions
Should a dentist sell the building with the dental practice?
Sell when immediate liquidity, diversification and a clean exit outweigh future rent and appreciation. Retain when the lease produces acceptable risk-adjusted cash flow and the seller is willing to remain a landlord.
How should rent be set after a dental-practice sale?
Use supportable market rent and define the premises, term, escalations, operating expenses, repairs, improvements, assignment and default. The rent must also fit the buyer's practice cash flow and financing.
Does selling California dental office real estate cause reassessment?
A California change in ownership generally causes the county assessor to reassess the transferred interest to current fair market value unless an exclusion applies. Entity-interest transfers and long leases can also require specialized review.
Can a dentist use a §1031 exchange for the dental building?
A qualifying exchange may defer gain on real property held for business or investment when all requirements are met. §1031 does not apply to the dental practice's equipment, goodwill or other non-real-property assets.
Should the dental practice and building have separate valuations?
Yes. Separate appraisals and agreements help distinguish real-estate value and market rent from dental-practice goodwill, equipment and operating cash flow.
