Every medical practice owner faces the lease-or-buy question eventually. Sometimes it’s forced by a lease expiration. Sometimes it comes with an expansion decision. Sometimes it’s a broker calling with a building for sale in your medical corridor. Occasionally it’s the disposition question at practice sale: keep the real estate, or sell it too?
The answer is almost never obvious, and it’s rarely just about money. This guide walks through the financial, operational, tax, and personal considerations that determine whether leasing or buying makes more sense for a given practice — and what the decision actually implies for how you’ll run the facility either way.
This isn’t financial or legal advice. Your CPA, real estate broker, lender, and attorney should run the numbers for your specific situation. What follows is the framework we’ve seen most practice owners use to reach a good decision.
Why Medical Practices Approach This Differently
Medical office real estate isn’t like general commercial real estate. A few things make the medical practice owner’s decision distinctive:
- You’re often both tenant and (potentially) landlord. Many practice owners buy the building through a separate LLC and lease to their practice — a common structure that moves rent from your practice into your personal wealth column.
- Your practice’s location is clinically load-bearing. Patient relationships, referral networks, and staff commutes are geographically anchored in a way most businesses’ aren’t. Moving hurts.
- You have specific improvements at risk. Exam rooms, plumbing for operatories, medical gas, X-ray shielding, waiting rooms designed around your patient flow — none of it is generic. Every dollar you spent making a space clinical is at risk when you leave a leased space.
- You have a practice sale on the horizon. Even if it’s 15 years out. That endgame shapes the right answer today.
- You’re the buyer of a specialized property. Medical office buildings trade to a fairly narrow buyer pool at fairly specific cap rates. That affects both the price you pay and the price you’ll get.
Any lease-or-buy analysis that ignores these is generic office-space advice with the word “medical” pasted on.
The Financial Comparison
The headline numbers are simple. What matters underneath them is not.
Leasing requires no down payment, produces a fully-deductible monthly business expense, and preserves capital for equipment, hiring, or expansion. It gives you a fixed occupancy cost you can budget against. It gives you nothing at the end.
Buying requires a down payment (typically 10% with SBA 504 financing, 20–30% with conventional commercial real estate loans), replaces rent with a mortgage payment plus operating costs, builds equity, captures appreciation, generates real depreciation tax benefits, and ties up capital that could have gone elsewhere. It gives you an asset at the end.
The right comparison is not “lease payment vs. mortgage payment.” That comparison is almost always wrong. The right comparison is total occupancy cost including all the pieces:
Leasing includes: base rent, CAM reconciliations, tax and insurance pass-throughs, tenant improvement amortization, annual rent escalations (typically 2.5–3.5%), and potential restoration costs at lease-end.
Buying includes: mortgage principal and interest, property taxes, property insurance (including windstorm in Florida), all maintenance and capital replacement, property management if you don’t self-manage, and the opportunity cost of your down payment.
Run those side by side over 10 and 20 years, with realistic escalation assumptions and realistic capital replacement reserves for the buy scenario, and one of them will be meaningfully better than the other. Usually — but not always — buying wins over a 10+ year horizon if you have the down payment and the location is stable. Under that horizon, or if capital is scarce, leasing usually wins.
The Operational Comparison
Money is one axis. Control is the other.
When you lease, you don’t fully control your facility. Major renovations require landlord consent (and often landlord contribution negotiations). Roof leaks are the landlord’s problem — unless your lease says otherwise, which many medical NNN leases do. HVAC replacement is a shared conversation you may or may not win. Signage, exterior appearance, and common-area quality are somebody else’s decision. If your landlord sells the building, you inherit a new landlord with new priorities.
When you buy, you control everything. Every renovation is your call. Every equipment replacement is your capital plan. Every roof, parking lot, and HVAC unit is your responsibility — including the ones you didn’t know were near end-of-life when you bought. If you find good tenants for extra suites, that’s rental income; if you find bad ones, that’s your problem.
Neither is universally better. What matters is whether the trade fits your practice. High-growth groups making rapid location decisions often lease deliberately to stay flexible. Established practices with a decade-plus commitment to a location often buy deliberately to control their environment and build equity.
Understanding Your Lease (If You Lease)
Most medical office leases in Florida are triple net (NNN) or modified NNN. In a true NNN lease, the tenant pays base rent plus pro-rata share of property taxes, property insurance, and common area maintenance (CAM). In an absolute NNN, the tenant is responsible for essentially everything, including structural components and roof.
Before you sign or renew, you need clear answers to a specific set of questions:
- What exactly does CAM include? Landscaping, parking lot maintenance, common HVAC, management fees? Ask for a three-year historical CAM reconciliation.
- Who replaces the roof? Who replaces rooftop HVAC units? Who repaves the parking lot? These are the “gotcha” items in medical NNN leases.
- What’s the tenant improvement allowance, and what happens to unamortized TI if you leave early?
- What are the rent escalation terms — fixed percentage, CPI, or market resets?
- What’s the restoration clause? Some medical leases require the tenant to return the space to shell condition, which can be a six-figure surprise at lease-end.
- Are personal guarantees required? For how long? Can you negotiate a burn-off?
- What are the assignment and subletting rights if you sell the practice?
- What’s the co-tenancy language? If a big anchor tenant leaves, do you have rights?
If you already lease and can’t answer these questions from your current document, that’s the audit to run before you renew.
The maintenance-responsibility questions matter operationally too. If you’re on the hook for HVAC service or replacement — and many medical NNN leases put you there — that’s a preventive maintenance program you need to actually run, because letting equipment fail from neglect can trigger both operational and lease-related consequences.
Understanding What You Own (If You Buy)
Buying a medical office building is buying a business. You are now responsible for the operation of a specialized facility, which includes:
- Deferred maintenance you inherited. This is the biggest post-close surprise for first-time medical office building owners. That 12-year-old rooftop unit the seller called “well-maintained” is a $25,000 replacement waiting to happen. A thorough building inspection and equipment inventory before close is not optional.
- Capital replacement planning. Roofs (20–25 years). HVAC (10–20 years by component). Parking lot (7–10 year seal/patch, 20–25 year resurface). Electrical infrastructure. Plumbing. Every one of these is a five- or six-figure event. If you don’t reserve for them, you’ll finance them under pressure.
- Ongoing preventive maintenance. HVAC filter changes and coil cleaning. Backflow testing. Fire panel monitoring. Generator testing. Roof inspections. Landscape and irrigation. Pest control. Elevator inspection if applicable. This is a program, not a series of reactions.
- Compliance and permitting. Any modification triggers permits. Signage rules. ADA obligations. If you’re a licensed facility, AHCA implications on the physical plant.
- Insurance. Property insurance including windstorm for Florida coastal counties (expensive), liability, business interruption. Higher deductibles are the usual response to Florida’s insurance market, which shifts more risk to your reserves.
- Property management decisions. Self-manage, hire a property manager, or hire a coordinated maintenance partner. Each has cost and control trade-offs.
The reason many practice owners underestimate the “buy” side isn’t the mortgage math — it’s this list. Facility ownership is real work, and it doesn’t stop.
The Tax and Wealth-Building Angle
This is where buying gets interesting for physician-owners specifically.
- Depreciation on the building (excluding land) reduces taxable income. A cost segregation study can accelerate depreciation on many components, front-loading the tax benefit.
- Mortgage interest is deductible.
- Property taxes and operating costs are deductible in the operating entity.
- The self-rental structure — owning the building through a separate LLC and leasing it to your practice — is common. It moves rent from your practice’s expenses into your personal wealth column, keeps the real estate on a separate risk-and-sale timeline from the practice, and lets you continue collecting rent from the practice buyer after you sell the practice. Talk to your CPA about self-rental rules (specifically the passive activity rules around self-rental); the structure needs to be set up correctly to work.
- 1031 exchanges let you defer gains when you eventually sell and reinvest in another property.
- Estate planning — commercial real estate is often a cleaner asset to pass to heirs than an operating medical practice.
The practice sale endgame is worth thinking about a decade before it happens. Many practice sales — especially to DSOs and MSOs — are structured as the buyer acquiring the practice while continuing to lease from the seller’s real estate entity. If you own the building, you have that option. If you lease, you don’t.
Florida-Specific Considerations
- No state income tax simplifies some of the personal analysis and makes the personal wealth-building angle of ownership more attractive than in high-tax states.
- Property tax appeals are worth running annually — commercial property valuations from the county appraiser are often high, and a successful appeal is real money.
- Windstorm insurance is a material line item in coastal counties. Get quotes before you’re in contract, not after.
- Hurricane preparedness — impact-rated windows, roof systems, generator readiness, and post-storm response are all owner responsibilities on a building you own. Post-storm damage that isn’t documented for insurance within the required window becomes your out-of-pocket cost.
- AHCA implications — if your facility is a licensed ambulatory surgery center, birth center, or hospital, a building change may trigger licensure implications. Any lease-vs-buy analysis for a licensed facility needs to run through the licensure review path.
When Leasing Usually Makes Sense
- Early-career practice with limited capital
- Uncertain about long-term location commitment
- Rapid growth or geographic market testing
- Multi-location group opening new sites where flexibility matters more than equity
- Time horizon under about 7–10 years in the location
- Preserving capital for equipment, hiring, or acquisition
When Buying Usually Makes Sense
- Established practice with a stable, growing patient base
- 10+ year commitment intended
- Strong local medical corridor with appreciation potential
- Down payment available without straining practice cash flow
- Personal wealth-building strategy that includes real estate
- Practice-sale plan that could include continued rental income
What MedServ Does Either Way
Whether you lease or buy, someone is running preventive maintenance, coordinating repairs, tracking service history, and answering “when was this last serviced?” when it matters. If you buy, that’s you (or someone you delegate it to). If you lease NNN, that’s still often you for a meaningful portion of the systems.
MedServ is built to be that operating partner across either scenario. If you’re a multi-location group, we run the program consistently across leased and owned sites so your operations director has one view of every location’s maintenance status, service history, and open issues — regardless of who signed which lease. If you buy a building and inherit deferred maintenance, we build the catch-up program and the ongoing PM cadence around it. If you renew a lease with new maintenance obligations, we run those obligations without your office manager becoming a facility manager.
The lease-or-buy question is a real estate and financial decision. The facility-runs-well question is what MedServ handles once that decision is made.
FAQ
How much down payment do I need to buy a medical office building? SBA 504 financing typically allows as little as 10% down for owner-occupied medical office buildings. Conventional commercial real estate loans usually require 20–30%. SBA 7(a) is more flexible but often at higher rates. Talk to a lender who specializes in medical practice real estate — not every commercial lender does.
Is it better to own the building through my practice or a separate LLC? Most CPAs recommend a separate LLC (or similar entity) that owns the real estate and leases to the practice. It separates the assets, opens up self-rental treatment for tax purposes, and lets you sell the practice and the real estate on independent timelines. Set this up with your CPA and attorney — the structure needs to be right from day one.
What’s a typical cap rate for medical office real estate? Cap rates vary by market, tenant credit, lease term, and property quality. Medical office in Florida secondary markets has typically traded in a range roughly comparable to other stabilized commercial real estate, with premiums for strong locations and long tenant leases. A local medical-office-experienced broker can give you current market numbers.
Should I sign a personal guarantee on my medical office lease? Landlords usually ask. Whether you should — and for how long — is negotiable and depends on your practice’s financial strength, the size of the space, and the deal economics. A common compromise is a burn-off guarantee that reduces or expires after a period of on-time performance. Never sign a personal guarantee without your attorney reviewing the lease.
How long do I need to stay to make buying pencil out? The general rule of thumb is that buying makes financial sense at roughly 7–10 years and up, with real advantage at 15+ years. But the number depends heavily on your specific down payment, financing terms, tax situation, and local market appreciation. Run the actual analysis with your CPA rather than relying on a rule of thumb.
What if I lease now and want to buy later? Two common paths: buy your current building when the current owner decides to sell (get right of first refusal in your lease if possible), or buy the next building when you outgrow or move on from the current one. Some practices deliberately lease their first 5–10 years to build capital and buy at their long-term location.
Thinking through a facility decision?
Whether you’re evaluating a purchase, a lease renewal, or a new build, MedServ can look at the operational side — what the facility will actually cost to run, what maintenance obligations the lease creates, and what the capital replacement picture looks like on a building you’re considering. Schedule a walkthrough and we’ll walk your current or prospective space with you.
