Buying an Existing Gym: A Due-Diligence Checklist

A gym for sale comes with a listing, and the listing is the seller's best day.

When you're buying a gym, you're buying the seller's word that the members will keep showing up and the lease will hold.

Due diligence is how you check both before you wire the money.

This checklist covers independent gyms and martial arts schools, in the order you'd check things. Franchise buyers, start with low-cost gym franchises.

Buy or Build

Build from scratch and your problem is an empty room. The cost to open a gym is real money spent before a single member walks in.

Buying a gym gets you a room that's already full, or at least the seller says it is.

You're paying for members and cash flow that exist today, and inheriting whatever is wrong with the place.

One catch if you plan to finance.

The SBA's lender rulebook counts buying all or substantially all of a business's assets, and continuing its operations, as a change of ownership. Buy only the equipment and don't carry on the seller's operations, and a lender may evaluate it as a start-up.

Read the Books Before the Pitch

Ask for three years of profit-and-loss statements and tax returns, plus at least two years of bank statements. Check that the three agree.

The SBA's lender rulebook calls this a "cash proof": rebuild the cash in and out from the bank statements, then reconcile it to the income statement and the tax return.

It requires the full review only at $3 million and up, so you'll run a lighter version yourself or pay a CPA to.

Question the add-backs

The number a seller leads with is usually seller's discretionary earnings, or SDE: profit with the owner's pay and certain other costs added back.

It's the most flattering number in the room, since it's before your salary and any loan payment.

‍What gym owners make shows what's left after both.

The SBA's rulebook lists five things its quality-of-earnings review has to document. It's required at $3 million and up, but it works as a checklist at any size.

Here's each one in a gym:

• Owner pay. An owner who teaches most of the classes is doing a job you'll pay someone to do.
• "One-time" costs. The same repair three years running isn't one-time.
• Related parties. Family on payroll, or rent paid to a building the owner holds.
• Deferred maintenance. Skipped repairs become yours the day you close.
• Cash versus accrual. Ask which one the books use and how front-desk cash gets recorded. Gym accounting basics explains the difference.

Prove the Members Are Real

Everything so far is the seller's version of the numbers. The member list is the part you can check yourself.

Recurring revenue you can count

Ask for a roster export: every member, with status, start and cancel dates, membership type, what they pay, and last attendance. Any decent system produces it in minutes. If it takes a week, that's an answer too.

From that file, count who's active and paying, who's frozen but still on the books, who's billed but hasn't been in for two months, and who's active with no card on file.

Count that last group first.

In Gymdesk's own benchmark of 4,594 gyms, which is one platform's data and mostly martial arts and combat sports schools, gyms collected about 92 cents of every dollar owed.

Close to $6 of every $8 that went uncollected came from members who never had a card on file.

Split last year's revenue into dues and one-time sales: belt tests, seminars, retail.

Retention you can calculate

Take everyone who joined 12 to 24 months ago and count how many are still active. That's your retention number.

For a reference point, the same benchmark found that nearly one in five new members quits inside 90 days, then churn settles at 2% to 3.5% a month. Use it to test the seller's story. Vital metrics for martial arts walks through the math.

Where the revenue sits

Ask what walks out the door if one thing changes.

If the owner teaches the flagship class or one partnership brings in the new members, that's concentration.

The SBA's quality-of-earnings review asks the same questions: customer concentration risk, contract continuity, and whether revenue and margins will hold after the sale.

Check What Actually Transfers

A purchase agreement lists what you're buying, and some of it needs someone else's approval before it moves to you.

None of this is legal or tax advice. It's the list of questions to bring your attorney and your CPA.

Contracts, waivers, and prepaid memberships

Your attorney reads every member agreement, starting with the assignment clause. It decides whether the contracts move to you at all.

Next, ask for the prepaid list: annual memberships paid in full, class packs, gift cards, credits. The seller already collected that cash, and you'd owe the classes. Put a number on it and negotiate it into the price.

Waivers were signed with the old business. Ask whether the waivers carry over or whether every member signs a new gym liability waiver at closing.

Your state may regulate gym memberships directly, and Texas does.

Its Health Spa Act counts a gym as "closed" when the seller sells and the buyer doesn't adopt or honor the existing members' contracts.

The same law says a registration certificate isn't transferable, so a buyer has to apply for their own within five days of taking ownership. It also lists martial arts equipment among a gym's facilities, so ask your attorney whether it covers a given school.

Ask for the insurer's claim history too, which is called a loss run. Our guide to gym insurance explains the coverage types.

Cards, accounts, and the member list

Stored cards live with the seller's payment processor, so ask early whether it will release the cards to you and what that costs.

Then list everything the business runs on: the phone number, the website and domain, the Google Business Profile, the social accounts, the software logins. Get each one named in the purchase agreement, with the roster and attendance history as a file.

Lease, Equipment, and the Building

Read the lease before you walk the floor.

The lease

Ask four questions:

• Can it be assigned to you, and does the landlord have to agree?
• How much time is left, and who controls the renewal options?
• Is there a personal guarantee, and whose name is on it?
• Who owns the buildout when the lease ends?

If an SBA loan funds the deal, the lender will care about the second one.

The 7(a) rulebook wants the lease term to equal or exceed the loan term, counting renewal options only you can exercise. It applies where leasehold improvements and attached equipment reach $500,000 or 30% of the loan or collateral, whichever is less.

Say you borrow $190,000. Thirty percent of that is $57,000, which a built-out gym floor can pass easily. Don't take a loan that outlasts your right to the room.

Equipment and buildout

Walk the floor with the equipment list in your hand. Match it to the depreciation schedule on the tax return, check what's owned versus leased or financed, and look for liens.

A list can't show the mats, flooring, HVAC, plumbing, and locker rooms. Those are the deferred-maintenance costs from the add-backs section, so price them now.

What a Fair Price Looks Like and How It Gets Financed

Independent gyms usually sell for about two to three times the owner's annual discretionary earnings, and the median sold gym went for $210,500.

The source is BizBuySell, a business-for-sale marketplace with figures from 400 gyms and fitness centers sold between 2021 and 2025.

It's one marketplace and includes franchise units, but these are real sales, which listings aren't.

The numbers from actual sales

Asking prices run high. BizBuySell says owners set asking prices above what the business would likely sell for, either as a negotiating move or because owners tend to overvalue their own gym.

The typical sold gym sat on the market about 171 days, so you have time to negotiate.

Size and owner involvement move the multiple. A gym with sales over $600,000 may sell near three times, and one under $250,000 may sell below two times.

Steady financials and low owner involvement push it up, and thin margins and a full-time owner pull it down.

IBBA, the business brokers' association, comes in a little lower.

Its Q2 2026 survey put businesses priced under $500K at roughly two times SDE, across all industries. BizBuySell's sold gyms cluster between 1.72 and three times, so read the two together as roughly two to three times the owner's annual discretionary earnings.

Terms matter as much as price

If an SBA 7(a) loan funds the deal, the rulebook shapes your offer.

These rules apply to loans from October 1, 2026, and a lender has the final word, so call one before you write an offer. Startup financing options covers the other routes.

Plan the First 90 Days Before You Close

Decide how the members hear about it before you sign. Abe Awad bought Subforce Jiujitsu & Muay Thai in New Jersey from its retiring founder and ran the handover as business as usual. In the Subforce story, he says:

Abe had a head start: he'd trained and taught at the school for years. If you're buying as an outsider, you don't get that head start, so the introduction matters more.

Before closing:

• Meet the members and coaches with the seller there.
• Keep the schedule, prices, and coaches steady at first.
• Decide what you'll say when people ask, and say it the same way every time.
• Put the seller's handover role in writing. An SBA loan lets the seller stay up to 24 months, and only as a consultant.

Get control of the data on day one

In week one, you want to know whether the seller's numbers were true, so load the data into your own system first.

Gymdesk's migration tools import members and memberships, attendance, payment history, products, and leads from CSV files, and member imports catch duplicates. Stored cards move from processor to processor, and Gymdesk connects to a supported processor account to sync the cards.

How fast that goes depends mostly on the old processor.

For a first look, gym reporting shows monthly member growth, churn, and how long members stay. Failed and missed payments show up in automated billing, which also exports payments and refunds as files for your bookkeeping software.

Compare it all to what the seller told you.

Reports only know what you've loaded. History from before the switch is only as good as the export the seller hands over, and your CPA still checks the books.
