Buying a Medical Practice vs. Starting From Scratch: What the 5-Year Numbers Actually Show
Compare the true 5-year financial outcomes, startup capital requirements, and hidden costs of buying an existing medical practice versus starting from scratch.
Every physician who considers practice ownership eventually faces the same fork: buy an existing practice or build one from zero. The conventional wisdom says buying is faster and starting is cheaper. Like most conventional wisdom in physician finance, it is partially right and mostly incomplete.
Starting a medical practice from scratch in 2026 requires between $500,000 and $900,000 in total capital — including the build-out, equipment, technology, staffing, and the working capital to survive the 6 to 12 months before consistent revenue arrives. Buying an existing practice requires a purchase price of $400,000 to $1,500,000 for a typical small to mid-sized practice — with revenue that begins on day one from a patient panel that already exists.
The total capital required is similar. The risk profile is different. The cash flow trajectory is dramatically different. And the 5-year wealth outcome — the number that actually determines whether either path was worth taking — depends almost entirely on variables that have nothing to do with which path you chose. They have to do with how well you executed it.
This article models both paths with real numbers, covers the hidden costs that derail each one, shows the 5-year financial comparison for a realistic family medicine practice scenario, and gives you the decision framework that determines which path makes sense for your specific situation.
The Cost Structure of Starting From Scratch
The most common financial planning error in de novo practice startups is underestimating the working capital requirement — not the build-out, not the equipment, not the technology. The working capital.
Here is why: a practice that opens its doors has zero revenue for the first 3 to 6 months because insurance credentialing takes 3 to 6 months to complete. Even after credentialing, reimbursements take 30 to 90 additional days to arrive after claims are submitted. Even after payments begin arriving, patient volume ramps gradually over 12 to 24 months before reaching a sustainable level.
Plan for 6 to 12 months of full operating expense coverage before consistent cash flow begins. A practice with $40,000 per month in operating costs needs $240,000 to $480,000 in startup working capital. That working capital requirement is the silent expense that most startup cost articles minimize — and it is often the variable that determines whether a startup practice survives its first year or closes before reaching full productivity.
The Complete Startup Cost Breakdown
Facility costs: $50,000 to $350,000
The range reflects the lease-versus-build decision. Leasing an existing medical office shell — a space already built for clinical use — costs $0 to $50,000 in tenant improvements. Leasing a raw commercial space and building it out to medical code requirements costs $100,000 to $350,000 depending on specialty. Medical practices need specialized medical-grade plumbing and electrical systems for zoning approval.
The lease terms matter as much as the build-out cost. A landlord who offers $50 per square foot in tenant improvement allowance (TIA) effectively subsidizes $50,000 to $150,000 of your build-out cost in exchange for a longer lease commitment.
Medical equipment: $50,000 to $300,000
The range is entirely specialty-driven. A psychiatry practice needs a laptop, a few chairs, and a HIPAA-compliant video platform. A gastroenterology practice starting from scratch needs endoscopy equipment that costs $150,000 to $300,000 before seeing its first colonoscopy patient.
The 2026 tax treatment makes equipment purchase significantly more favorable than leasing for well-capitalized startups: Section 179 allows immediate deduction of up to $2.56 million in medical equipment purchases for 2026. Bonus depreciation offers 100 percent immediate deduction with no dollar limits for equipment purchased after January 19, 2025.
Technology infrastructure
$15,000 to $60,000
EHR implementation, billing software, practice management system, patient portal, cybersecurity compliance. Most EHR vendors require implementation fees of $5,000 to $25,000 for small practices, plus ongoing monthly subscription costs.
Staffing costs pre-revenue
$80,000 to $200,000
You need staff before the first patient arrives. At $20,000 to $40,000 per month in staff payroll, the 3 to 6-month pre-revenue period represents $60,000 to $240,000 in compensation paid before a single dollar of collections arrives.
Credentialing and licensing: $5,000 to $20,000
Beyond the physician license, the practice entity needs its own credentialing with Medicare, Medicaid, and each commercial payer — a process that takes 3 to 6 months per payer and must be initiated before opening.
Marketing and patient acquisition: $10,000 to $50,000 in year one
A de novo practice starts with zero patients. Attracting patients requires website development, Google Business Profile optimization, physician directory listings, and referral relationship development.
The complete startup capital requirement:
| Cost Category | Low End | High End |
|---|---|---|
| Facility / build-out | $50,000 | $350,000 |
| Medical equipment | $50,000 | $300,000 |
| Technology / EHR | $15,000 | $60,000 |
| Pre-revenue staffing (6 months) | $80,000 | $240,000 |
| Working capital reserves | $120,000 | $300,000 |
| Credentialing and licensing | $5,000 | $20,000 |
| Marketing and launch | $10,000 | $50,000 |
| Legal / entity setup | $5,000 | $20,000 |
| Total | $335,000 | $1,340,000 |
The realistic all-in startup cost for a solo primary care practice in a moderate cost-of-living market falls in the $450,000 to $700,000 range. For a complete deep-dive, see our Guide to Medical Practice Startup Costs.
The Cost Structure of Buying an Existing Practice
Buying an existing practice replaces the build-out, equipment procurement, and patient acquisition problems with one transaction: a purchase price that reflects the practice's established value.
How medical practices are valued:
Medical practices typically sell for 2.5 to 4 times EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization. A medical practice with $300,000 EBITDA might sell for $750,000 to $1,200,000. Valuation depends on location, patient demographics, payer mix, equipment condition, competition, and growth potential.
For a full explanation of how practice valuations are calculated, see our Medical Practice Partnership Buy-In Guide or run your numbers through our Practice Valuation Calculator.
What the purchase price buys:
- Patient panel: established patients booking from day one
- Payer contracts: existing credentialing (eliminates the 3-6 month gap)
- Staff: employees who know the workflows
- Equipment: functional medical equipment
- EHR and technology: an operational system
- Goodwill: reputation, brand, and community presence
What it does NOT buy:
- Patient loyalty: some attrition is inevitable
- Staff retention: key staff may leave during transition
- Clean liability: you inherit AR history and vendor relationships
The Attrition Risk — Quantified
The patient panel attrition following a physician transition is the most consistently underestimated risk in medical practice acquisitions. Industry data suggests that 10 to 35 percent of an existing patient panel may leave following a physician change.
On a practice collecting $700,000 annually, a 20 percent patient attrition event reduces year-one collections to $560,000 — a $140,000 revenue gap that must be absorbed while the new owner simultaneously services acquisition debt.
The hidden costs of acquisition:
- Professional due diligence: A healthcare CPA reviewing three years of financial statements. Cost: $3,000 to $8,000.
- Healthcare attorney review: Contract review, asset purchase agreement negotiation. Cost: $3,000 to $10,000.
- Independent practice valuation: Third-party appraisal from an ASA or ABV-certified healthcare valuator. Cost: $3,000 to $8,000.
- Transition overlap period: Paying both the selling physician and operating the practice simultaneously during the 30-90 day handoff.
Total transaction costs for a well-executed acquisition: $15,000 to $30,000 in professional fees above the purchase price.
The 5-Year Financial Model: Side by Side
This is the calculation that actually answers the question. Not which path costs less to start — but which path produces more wealth over the first 5 years of ownership.
The scenario: A family medicine physician purchasing or starting a solo practice in a mid-sized market. Target: 2,500 active patients, $800,000 in annual gross collections at maturity, 55 percent overhead ratio, $360,000 net physician income at steady state.
Path A: Starting From Scratch
Year 0 (pre-opening): $585,000 Capital deployed
Financed through a practice startup loan.
Year 1: The Credentialing Gap
Gross collections: ~$250,000. Operating loss: -$100,000.
Physician income: $0–$50,000
Year 2: Building the Panel
Gross collections: ~$480,000.
Physician income: ~$115,000
Year 3: Approaching Maturity
Gross collections: ~$640,000.
Physician income: ~$203,000
Year 4: Full Productivity
Gross collections: ~$800,000.
Physician income: ~$275,000
Year 5: Equity Building
Physician income: ~$290,000
Net practice equity: ~$470,000
Path B: Buying an Existing Practice
Year 0: Acquisition ($600k purchase)
Total capital deployed: $625,000 (SBA 7(a) loan).
Year 1: Immediate Revenue
Gross collections: ~$600,000 (20% attrition).
Physician income: ~$182,400
Year 2: Stability Established
Gross collections: ~$720,000.
Physician income: ~$236,400
Year 3: Growing
Gross collections: ~$800,000.
Physician income: ~$272,400
Year 4: Full Ownership Economics
Loan paydown meaningful.
Physician income: ~$285,000
Year 5: Established Ownership
Physician income: ~$295,000
Net practice equity: ~$435,000
The 5-Year Wealth Comparison
| Metric | Start From Scratch | Buy Existing |
|---|---|---|
| Year 1 income | $0–$50,000 | $182,400 |
| Year 2 income | $115,000 | $236,400 |
| Year 3 income | $203,000 | $272,400 |
| Year 4 income | $275,000 | $285,000 |
| Year 5 income | $290,000 | $295,000 |
| 5-year cumulative income | $933,000 | $1,331,000 |
| Net practice equity at year 5 | $470,000 | $435,000 |
| 5-year total wealth creation | $1,403,000 | $1,766,000 |
The acquisition path produces approximately $363,000 more in total 5-year wealth — primarily because the income gap in years 1 through 3 for the startup path is substantial and does not fully close before year 5.
The important caveat: This model assumes 20 percent patient attrition in the acquisition and a normal credentialing ramp in the startup. Change either assumption and the comparison shifts.
The Decision Framework: When Each Path Wins
🏢 Buy an existing practice when:
- You want income from month one. A physician with student loan obligations and family commitments cannot typically absorb 2 years of below-market income.
- You are entering an established referral network. Building that network from zero takes 3 to 5 years in most markets.
- The existing infrastructure has value you cannot easily replicate. A dermatology practice with an operating MOHS surgery suite represents massive sunk capital costs.
🌱 Start from scratch when:
- No suitable acquisition target exists. In some markets, there simply are no practices for sale that meet your criteria.
- You want to build it exactly your way. Adapting an existing practice with ingrained culture is often harder than building a new one correctly from day one.
- The acquisition price exceeds fundamental value. Startups become attractive when the acquisition alternative is overpriced.
- Your working capital is secured. You have adequate cash reserves to absorb the startup's income ramp period.
Frequently Asked Questions
Is it cheaper to buy or start a medical practice?
The total capital required is similar for most practice types — $450,000 to $900,000 for a startup and $400,000 to $1,200,000 for an acquisition of a comparable practice. The startup's costs are spread across build-out, equipment, and working capital. The acquisition's cost is concentrated in the purchase price plus transaction costs. The more meaningful financial difference is the income trajectory — acquisitions produce income from day one, while startups require 12 to 24 months to reach comparable physician income levels.
How long does it take for a startup medical practice to become profitable?
A well-structured medical practice can reach break-even within 2 months of launch in favorable scenarios — but the more realistic timeline for a primary care practice is 12 to 24 months before consistent profitability, and 3 to 5 years before the practice reaches its full potential revenue level. The credentialing gap, patient panel ramp, and debt service burden all compress profitability in the first 2 years.
What is the biggest financial risk in buying a medical practice?
Patient attrition following the physician transition. An existing practice that loses 30 to 40 percent of its patient panel in the first year — because patients followed the departing physician or simply did not transfer loyalty to the new owner — produces significantly less revenue than the acquisition price assumed. Thorough transition planning, including a formal introduction period with the selling physician, is the most effective mitigation for this risk.
Can I get a loan to buy or start a medical practice?
Yes. SBA 7(a) loans up to $5 million are the most common financing vehicle for both acquisitions and startups, offering 10-year terms for working capital and practice purchase. Conventional practice loans from healthcare-specialized banks are available with shorter terms and in some cases faster approval. For a complete comparison of practice financing options, see our practice loans review page.
What is the most underestimated cost in starting a medical practice?
Working capital. The credentialing gap — the period between when a practice opens and when consistent insurance reimbursements begin arriving — requires 6 to 12 months of full operating expense coverage. A practice with $40,000 per month in operating costs needs $240,000 to $480,000 in startup working capital. Most physician startup cost estimates focus on equipment and build-out while dramatically underestimating the cash needed to survive before revenue reaches operating expense levels.
