For most independent physician practice owners, occupancy is the second-largest expense category after staffing. Whether you lease or buy your medical office space is one of the most consequential financial decisions you will make — affecting cash flow, tax liability, balance sheet, and practice flexibility for a decade or more.
This guide provides a structured financial comparison of leasing versus buying medical office space, with break-even analysis, cost breakdowns, and decision frameworks informed by commercial real estate data and SBA lending guidelines.
Lease Types Explained
Understanding lease structures is essential because the type of lease directly determines your true occupancy cost. There are three primary types used in medical office space:
| Lease Type | What It Includes | Typical Base Rent (Annual PSF) | Best For |
|---|---|---|---|
| Gross Lease (Full Service) | Rent + all operating expenses (CAM, taxes, insurance, utilities, janitorial) | $30–$55 | Predictable costs; smaller practices that want a single monthly payment |
| Net Lease (Triple Net / NNN) | Base rent + tenant pays share of CAM, property taxes, and insurance separately | $18–$32 (base) + $8–$15 (NNN) | Larger practices; those wanting to control their own operating expense decisions |
| Modified Gross Lease | Rent + some expenses included (typically utilities and janitorial); tenant pays CAM, taxes, and insurance | $24–$42 | Middle ground; moderate-sized practices |
Rent ranges are approximate for Class B medical office space in mid-sized metropolitan markets (200K–1M population), 2025–2026. Class A space in major metros can command $45–$70+ PSF on a gross basis. Source: CBRE Medical Office Market Reports, Colliers Healthcare Research.
Key trap: In a triple-net lease, the landlord passes through operating expense increases. CAM (Common Area Maintenance) escalations typically run 3–5% annually, meaning your effective rent grows every year even if base rent is flat.
Costs of Buying Medical Office Space
Buying commercial real estate involves costs that many physician owners underestimate.
| Cost Component | Typical Amount | Notes |
|---|---|---|
| Down payment | 20–30% of purchase price | SBA 504 requires 10–15% down; conventional commercial loans require 20–30% |
| Purchase price (2,000–4,000 sq ft) | $400K–$1.2M | Depends on market; $200–$350 PSF typical for medical office |
| Mortgage payment (monthly) | $3,500–$8,000 | Rate-dependent; SBA 504 offers 25-year amortization |
| Property taxes (annual) | $8,000–$24,000 | Varies by location; typically 1–3% of assessed value |
| Building insurance (annual) | $3,000–$10,000 | Commercial property insurance; higher for medical with specialized build-outs |
| Maintenance & repairs (annual) | $5,000–$15,000 | Budget 1–2% of property value annually |
| CAM (if multi-tenant building) | $4–$8 PSF annually | Common area maintenance, snow removal, landscaping, etc. |
| Capital reserves | $10,000–$30,000/year | For roof, HVAC, parking lot replacement over time |
Costs of Leasing Medical Office Space
| Cost Component | Typical Amount | Notes |
|---|---|---|
| Security deposit | 2–3 months' rent | Typically $10K–$20K; returned at lease end (minus damages) |
| Tenant improvement (TI) allowance | $15–$60 PSF | Landlord may contribute $20–$40 PSF; tenant pays the excess |
| Monthly base rent | $4,000–$12,000 | 1,500–3,000 sq ft at $24–$48 PSF |
| Annual rent escalations | 2–4% per year | Built into the lease; compounds over the term |
| Moving costs (at lease end if relocating) | $15K–$50K | Plus downtime during the move; often overlooked |
| Broker commission (if applicable) | 4–6% of total lease value | Usually paid by landlord, factored into rent |
5-Year Cost Comparison: Lease vs. Buy
The table below models a realistic comparison for a 2,500 sq ft medical office in a mid-sized market, assuming a 5-year holding period:
| Cost Category | Lease (NNN, 5-Year Term) | Buy (SBA 504, 25-Year Amortization) |
|---|---|---|
| Monthly base payment | $8,333 ($40 PSF) | $5,672 (mortgage @ ~7.5%) |
| Monthly NNN / operating expenses | $2,500 ($12 PSF) | $2,500 (taxes, insurance, CAM) |
| Monthly maintenance reserve | $0 (landlord's responsibility) | $1,042 ($12,500/year) |
| Total monthly occupancy cost | $10,833 | $9,214 |
| Total 5-year cost (cash outlay) | $650,000 | $553,000 |
| Upfront capital required | $30,000–$50,000 | $100,000–$150,000 |
| Equity built after 5 years | $0 | $90,000–$120,000 |
| Tax benefit (mortgage interest deduction) | $0 (rent is fully deductible) | Interest + depreciation deduction |
| Net 5-year effective cost | $650,000 | $433,000–$463,000 |
Assumptions: 2,500 sq ft, purchase price $625K ($250 PSF), 15% down ($93,750) via SBA 504, 25-year amortization at 7.5% blended rate, 3% annual rent escalation for lease, 2% annual property tax increase. Actual results vary by market and terms.
The breakeven period — the time after which buying becomes cheaper than leasing — typically occurs between year 3 and year 5 for most medical office properties. A practice that stays in the same space for 7+ years almost always comes out ahead financially by owning.
Break-Even Analysis by Practice Size
| Practice Size | Typical Square Footage | Lease Cost (5-Year) | Buy Cost (5-Year Net) | Break-Even Year |
|---|---|---|---|---|
| Solo practitioner | 1,200–1,800 | $360K–$540K | $250K–$380K | 3–4 years |
| Small group (2–3 providers) | 2,000–3,500 | $600K–$950K | $430K–$680K | 3–5 years |
| Medium group (4–6 providers) | 3,500–6,000 | $1M–$1.6M | $750K–$1.2M | 4–6 years |
| Large group (7+ providers) | 6,000–12,000 | $1.8M–$3.2M | $1.3M–$2.4M | 5–7 years |
Analysis assumes mid-sized market, Class B medical office space. Larger practices benefit more from economies of scale in ownership but have more complex space needs. Break-even year may extend if the practice requires significant tenant improvements that are not fully covered by the landlord under a lease.
SBA 504 Loan Program for Owner-Occupied
The SBA 504 loan program is the single most favorable financing vehicle for physician practice owners who want to buy their office space. Key terms:
| Feature | SBA 504 Loan | Conventional Commercial Loan |
|---|---|---|
| Minimum down payment | 10–15% | 20–30% |
| Interest rate type | Fixed (50% of loan) | Variable or fixed at higher spread |
| Amortization period | 25 years | 15–20 years |
| Owner-occupancy requirement | 51% minimum | None typically |
| Personal guarantee | Required (but no blanket lien) | Required (full recourse) |
| Typical closing time | 60–90 days | 30–60 days |
| Maximum loan amount (2026) | $5.5M for green projects | Varies by lender |
Source: U.S. Small Business Administration, "504 Loan Program Overview," 2026. Interest rates are based on 5- and 10-year Treasury plus spread; the debenture portion is fixed at a below-market rate.
The 504 program's low down payment (10–15% vs. 20–30% conventional) and 25-year amortization make ownership much more accessible for physician practices. The trade-off is higher closing costs and a longer closing timeline.
When Each Option Makes Sense
Leasing is likely the better choice if:
- You expect to need more (or less) space within 3–5 years
- You are in the first 2–3 years of practice ownership and capital is constrained
- Your practice is in a market where sale prices are inflated relative to rental rates (price-to-rent ratio above 20)
- You are unsure about the long-term viability of the location
- You want to preserve borrowing capacity for practice operations or equipment
- You prefer predictable, capped occupancy costs with no capital expenditure surprises
Buying is likely the better choice if:
- You plan to practice in the same location for 7+ years
- You have the capital for a 10–15% down payment via SBA 504
- You want to build equity and have an asset that appreciates over time
- You want to control your occupancy costs long-term and avoid rent escalation
- You are interested in the tax benefits of real estate ownership (depreciation, interest deduction, Section 179 for improvements)
- You may eventually lease excess space to other providers, creating ancillary income
Location Flexibility vs. Equity Building
The biggest qualitative trade-off is flexibility versus equity. Leasing gives you the ability to relocate as your practice grows or as demographics shift. Buying gives you a forced savings vehicle and a hedge against rent inflation.
Consider this: over a 20-year career, a physician who buys their office space and pays off the mortgage will have a fully owned asset worth $500K–$1.5M (depending on market appreciation). The physician who leases for 20 years will have spent $1.5M–$3M in rent and have nothing to show for it — but they had the flexibility to move three times as their practice evolved.
A middle path: buy a space slightly larger than your current needs and sublease the excess to another provider. This gives you real estate income, covers part of your mortgage, and retains some flexibility.
