A startup gives you full control but opens at zero cash flow. A leased 4-operatory startup at standard finish plans at $746,000 to $824,000 all-in under the Alithos model. An acquisition buys existing collections, so lenders underwrite its real cash flow against the 1.25x coverage benchmark many use. Choose by how much room your market has, what is actually for sale near you, and whether you would rather build a team or lead an inherited one.
Both paths end with your name on the door. They get there with very different risk curves. The right answer is personal, but it isn't mysterious. It comes down to a few honest comparisons and one honest look at your temperament.
I don't sell practices, broker them or value them. I'm not a broker, appraiser, lender, attorney or CPA, and I take no commissions or referral fees from anyone on either side of a deal. What I do is build the budget for the facility side: the startup you'd open instead, or the space you'd move an acquired practice into. For a practice valuation, hire an independent valuation professional who works for you, not the seller.
How do a dental startup and an acquisition compare?
Here is the short version. Each row is a trade-off, not a verdict.
| Factor | De novo startup | Acquisition |
|---|---|---|
| Up-front cost | $746K–$824K for a leased 4-op at standard finish (Alithos model, incl. $85,000 working capital) | Purchase price, commonly set as a share of collections, plus working capital, updates and closing costs |
| Day-one cash flow | Zero. You build it patient by patient | Existing collections from the first Monday |
| How the lender underwrites it | Projections, your budget and your working capital plan | The practice's historical cash flow, tax returns and add-backs |
| Control | Total: location, size, design, systems, brand, team | Inherited: charts, staff, fee schedule, payer mix, equipment, lease |
| Main risk | A slow ramp that outlasts your working capital | Paying for cash flow that doesn't survive the transition |
| Facility | New and sized to your plan | Whatever the seller built, at whatever age |
| Who sets the price | Your choices, contractors and dealers | Negotiation with the seller, guided by a valuation |
Is it cheaper to buy a dental practice or start one?
Not by default. The two price tags measure different things. A startup budget buys a facility and a runway. An acquisition price buys a facility plus a patient base and its cash flow. Comparing them on sticker price alone misses the point.
The startup side is the easier one to model. Here is how the Alithos estimator builds a 4-operatory startup in leased space at standard finish. These are planning assumptions, not survey data or a quote.
| Line | Model assumption | 4 ops, 2,000 sq ft |
|---|---|---|
| Construction | $170 per sq ft (lease, standard); 500 sq ft per op | $340,000 |
| Equipment | $42,000 per op | $168,000 |
| Imaging | Sensors + pano | $60,000 |
| Cabinetry | 10% of construction | $34,000 |
| Soft costs | 12% of construction | $40,800 |
| IT + furniture | $45,000 + $3,000 per op | $57,000 |
| Working capital | Flat default | $85,000 |
| Total | Point estimate; range is ±5% | $784,800 ($746K–$824K) |
For context, an ADA News expert column says opening a practice often takes $500,000 at minimum (ADA News, 2025). The model sits above that floor, and it includes working capital, cabinetry and soft costs as their own lines. The full line-by-line picture is in the dental practice startup costs guide.
The acquisition side has no model I can give you, because the price comes from a specific practice. Acquisitions are commonly priced as a share of collections, and the right share depends on that practice's profit, condition and patient base. Get an independent valuation. Then add what the purchase price doesn't cover: working capital, deferred equipment and facility updates, technology changes, legal and accounting fees, and the cost of any transition period.
How do lenders evaluate a startup vs. an acquisition?
Both get measured on debt-service coverage (DSCR). The common benchmark is cash flow of at least 1.25 times all debt payments and living costs. One dental lender writing in ADA News calls that a guideline, not a strict minimum (ADA News, 2026). What differs is where the cash flow number comes from.
Acquisition: actual numbers, adjusted
For a purchase, the lender starts from the practice's real history: collections minus overhead, from tax returns and financial statements. Then it adds back items that won't continue under you, such as the seller's own salary, depreciation, interest, and personal or one-time expenses run through the practice. The result is the cash flow you're buying. The lender divides it by your new debt service plus your personal obligations.
The number exists before you sign. Your job is to verify it, not trust a one-page summary. Add-backs are where optimism hides. The same ADA News column says overhead in a well-run general practice typically runs 58% to 68% of collections, in that lender's view. If a listing shows overhead far below that, ask why. That column also cites a cash reserve at closing often in the $50,000 to $75,000 range.
Startup: projections, so the budget is the application
A startup has no history, so the same ratio runs on projections. The quality of your budget is the quality of your loan application. A verified space program, equipment budget and ramp plan is what lets a lender price your risk instead of guessing at it. Here is the debt side, on the model's assumptions of 15 years at 8.25%:
| 4-op leased startup (model) | Amount |
|---|---|
| Project total, if fully financed | $784,800 |
| Monthly payment (15 years, 8.25%) | $7,614 |
| Annual payment | $91,364 |
| Cash flow needed for that payment at 1.25x | $114,205 a year |
That last line covers the practice loan only. A global calculation adds your living costs and personal debt, including student loans. Run your own version in the DSCR calculator, and see what else lenders look at and the financing guide for loan types and terms.
On the SBA side, 7(a) loans list "changes of ownership (complete or partial)" and short- and long-term working capital among permitted uses, up to a $5 million maximum (SBA). Working capital and equipment maturities generally run up to 10 years, and real estate up to 25 (SBA). Conventional dental lenders set their own terms, so ask each one in writing.
What should you check before buying a dental practice?
Treat the seller's numbers as a claim to test. Your attorney, CPA and valuation professional each own part of this. The list below is what I'd want answered before the budget conversation even starts.
- Charts and active patients. How many patients were actually seen in the last 12 to 24 months, not how many charts exist.
- Fee schedule. Whether fees are current for the market or years behind, and what raising them would do.
- Payer mix. The split between fee-for-service, PPO plans and public programs, and the write-offs each carries.
- Staff. Tenure, pay against the local market, and who is likely to stay through the transition.
- Lease. Remaining term, renewal options, assignment rights, rent escalations and relocation clauses. Your attorney reviews before you sign.
- Equipment age. Chairs, delivery units, compressor, vacuum, sterilization and imaging, with what needs replacing in the next few years.
- Accounts receivable. How old it is, how it will be collected, and whether it is in or out of the price.
- Tax returns. Several years of practice returns and statements, reconciled to the production and collection reports.
Deferred maintenance. A practice can show strong cash flow partly because the seller stopped reinvesting. Price the next few years of equipment and facility updates into your plan, or the cash flow you bought will go straight back into the building.
How long does a dental startup take to reach a full schedule?
There is no published standard, and anyone who quotes one for your market is guessing. In my own planning I budget for 12 to 24 months to a full schedule, depending on the market, marketing and how many patients follow you. That is a planning assumption, not a promise.
What matters is that the ramp is funded. Insurance collections lag production, while rent, payroll and loan payments start on schedule. The Alithos estimator carries $85,000 of working capital as a default, and the right number for you depends on your overhead and how fast you expect to grow. The working-capital post walks through the math. An acquisition skips most of this ramp, which is a large part of what you pay for.
What does the dental ownership market look like?
A few numbers from the ADA Health Policy Institute (HPI) set the scene. There were 205,088 professionally active dentists in the U.S. in 2025, about 60 per 100,000 people (ADA HPI). In 2023, 72.5% of dentists were private-practice owners, down from 84.7% in 2005. About 16% were affiliated with a DSO in 2024 (ADA HPI).
The same HPI research puts average gross billings for a private-practice general dentist at $965,660 in 2025, with average net income of $215,320 (ADA HPI, 2025). Gross billings are not collections, so don't use them as a collections target. They are a useful sanity check on any projection, startup or acquisition.
What these numbers don't tell you is your market. Ownership is still the path most dentists take, but whether your town has room for a new office, or a good practice for sale, is a local question. Drive it, count the offices, and talk to the people who know which owners are near retirement.
What is acquire-then-relocate?
It is a third path. You buy an existing practice for its patients and cash flow, then move it into a space sized and designed for your plan. You get day-one collections and, after the move, a facility you chose.
It works best when the patient base is solid but the building isn't: an expiring lease, too few operatories, or a suite that can't take the equipment you want. The cost is that you finance two things, the purchase and the new facility, and the lender will look at coverage on both. Time the move around the lease and the transition, so patients and staff aren't asked to absorb two big changes at once. The relocation guide covers the facility side in detail.
When does each path win?
A startup tends to win when
- Your market has room, and the offices for sale near you don't fit the practice you want to run.
- You have a clear clinical identity, such as a technology-heavy or specialty-leaning practice, that existing offices can't deliver.
- You can fund a real ramp, with working capital that covers a slow first year.
- You want to hire and train your own team from the start.
An acquisition tends to win when
- Good practices are actually for sale where you want to live.
- The seller's numbers survive independent diligence and a valuation.
- Buying existing cash flow beats building it, given your debt and living costs.
- The seller will stay through a planned transition to introduce you to patients.
Acquire-then-relocate tends to win when
- The patient base is strong but the facility, lease or layout is the limit.
- The combined debt still clears your lender's coverage test.

Which path fits your temperament?
Startups reward builders who can sell. Acquisitions reward operators who can lead an inherited team through change. Neither is braver. The expensive version of either is the one you chose because someone selling it to you was persuasive on the day you were most excited.
Before you commit to either, get the startup number. Even if you end up buying, knowing what the build-it-yourself path costs gives you a reference point for any asking price. My Feasibility Check ($2,500 flat, credited toward the Budget Plan) is a go / no-go screen on the startup side: space and site fit, a high-level equipment budget range and a DSCR pre-check against the 1.25x standard. It doesn't value the practice you're looking at. It tells you what the alternative costs.
Startup vs. acquisition FAQ
Is it cheaper to buy a dental practice or start one?
Not by default. A leased 4-operatory startup at standard finish plans at $746,000 to $824,000 all-in under the Alithos model, including $85,000 of working capital. An acquisition price depends on the specific practice and is commonly set as a share of collections. Compare total cost, cash flow and risk, not sticker price, and get an independent valuation.
How do lenders evaluate a dental practice acquisition?
Lenders start from the practice's actual history: collections minus overhead from tax returns and statements, plus add-backs such as the seller's salary, depreciation and one-time expenses. They divide that cash flow by your new debt payments and living costs. Many dental lenders look for coverage of at least 1.25x, as a guideline rather than a strict rule.
How long does a dental startup take to reach a full schedule?
There is no published standard. In my own planning I budget 12 to 24 months to a full schedule, depending on the market, marketing and how many patients follow you. That is a planning assumption, not a promise. Fund the ramp with working capital; the Alithos estimator uses $85,000 as a default.
What is acquire-then-relocate?
Acquire-then-relocate means buying an existing practice for its patients and cash flow, then moving it into a new space sized for your plan. You get day-one collections and a facility you chose. The trade-off is financing both the purchase and the new space, so the combined debt has to clear your lender's coverage test.
What should I check before buying a dental practice?
Check active patients rather than total charts, the fee schedule, payer mix, staff tenure and pay, the lease terms and assignment rights, equipment age, accounts receivable, and several years of tax returns reconciled to production reports. Your attorney, CPA and an independent valuation professional should each review their part before you sign.
Can I finance working capital on an acquisition?
Often, yes. The SBA lists changes of ownership and short- and long-term working capital among permitted 7(a) loan uses, with working capital maturities generally up to 10 years. One dental lender writing in ADA News cites a cash reserve at closing often in the $50,000 to $75,000 range. Conventional lenders set their own terms, so ask each one.
