Due Diligence Checklist for Buying a Gym or Fitness Business

Export a full active member list from the billing platform (Mindbody, ClubReady, ABC Financial, or equivalent) showing member name, join date, membership tier, monthly rate, and last payment date.

This is the ground truth of recurring revenue. Sellers frequently quote 'active members' using a definition that includes frozen, past-due, or promotional accounts. You need actual paying members to calculate real MRR.

Red flag: Seller refuses to export raw data or provides a summary PDF instead of a live platform export — this suggests manual manipulation or inflated member counts.

Reconcile 24 months of MRR against actual bank deposits on a month-by-month basis. Look for consistent alignment between the billing platform totals and what actually cleared the bank.

MRR figures in a CIM are often taken from the billing platform, which shows what was billed — not what was collected. Chargebacks, failed payments, and refunds can create a 5–15% gap between billed and collected revenue.

Red flag: A persistent gap greater than 8% between billed MRR and bank deposits, or bank deposits that spike in months before a sale listing, may indicate revenue manipulation.

Calculate monthly churn rate over the past 24 months. Divide members lost per month by total members at the start of that month. Benchmark against the industry standard of under 5% monthly churn for a healthy gym.

Churn is the single biggest destroyer of gym value post-close. A gym with 400 members and 8% monthly churn will lose nearly half its base within a year. This directly affects your debt service coverage if you're using SBA financing.

Red flag: Monthly churn consistently above 6%, churn that spikes in the 6 months immediately preceding the sale listing, or a seller who cannot produce historical churn data at all.

Break down the membership mix by contract type: month-to-month, annual prepaid, annual EFT, and corporate/employer accounts. Calculate the percentage of revenue each type represents.

Month-to-month memberships can evaporate quickly after an ownership change. Annual contracts or corporate wellness agreements provide revenue certainty during the transition period and are more defensible in an SBA loan underwriting.

Red flag: More than 60% of members on month-to-month agreements with no long-term commitments, or a heavy reliance on a single corporate account representing more than 20% of membership revenue.

Identify the top 20% of revenue-generating members (high-tier memberships, frequent personal training buyers, retail spenders). Assess whether these relationships are tied to the seller personally.

High-value members who train exclusively with the seller or attend only the seller's classes represent a concentration risk. Their departure post-close can disproportionately impact both revenue and community culture.

Red flag: The seller personally trains more than 30% of the top revenue members, or multiple high-value members have stated to staff that they will 'follow the owner' to a new gym.

Review average revenue per member (ARPM) over 24 months, segmented by membership tier and ancillary revenue (personal training, classes, nutrition, retail).

ARPM tells you how effectively the gym monetizes its base beyond the base membership fee. A gym with $65 ARPM is more valuable than one with $45 ARPM of the same size, because diversified revenue is more resilient to churn.

Red flag: ARPM declining over the past 12 months, or personal training revenue that is entirely concentrated with one or two trainers who may not stay post-close.

Request the new member acquisition data for the past 24 months — how many new members joined each month and through what channel (referral, social media, paid ads, walk-in, corporate deal).

A gym that is not replacing churned members with new ones is shrinking. Understanding acquisition channels also tells you whether growth is dependent on the seller's personal social following or referral network.

Red flag: New member acquisition declining over the past 3–4 consecutive quarters, or more than 50% of new members citing the owner personally as the reason they joined.

Verify that all membership contracts are assignable to a new owner and confirm that member billing agreements will survive the ownership change without requiring member re-enrollment.

If membership contracts are not assignable, or if the billing platform requires a new merchant account setup that forces re-enrollment, you could trigger mass cancellations at close — the worst possible moment.

Red flag: Membership agreements that include owner-specific language, a billing processor that requires a 30–60 day re-enrollment window, or a seller who has never reviewed contract assignability.

Obtain and review the full lease agreement including all amendments, side letters, and landlord correspondence. Confirm the remaining lease term, base rent, rent escalation clauses, and renewal option terms.

SBA lenders require lease term to equal or exceed the loan term (typically 10 years including options). A lease with 3 years remaining and no renewal options will either kill the SBA deal or require a costly lease renegotiation before close.

Red flag: Fewer than 5 years remaining on the lease with no exercised or exercisable options, or rent escalation clauses that will push rent above 12–15% of projected revenue within the next 3 years.

Review the assignment clause specifically. Confirm whether landlord consent is required, what the landlord's approval criteria are, and whether there is a time limit on the landlord's response.

Most commercial leases require landlord consent to assign. An uncooperative landlord can delay close by 60–90 days or extract rent concessions or personal guarantee requirements as a condition of consent.

Red flag: A lease with a blanket prohibition on assignment, a landlord who is known to be difficult or has previously rejected assignment requests, or a seller who has not yet approached the landlord about the pending sale.

Determine whether the seller is operating under a personal guarantee on the lease, and negotiate how that guarantee will be handled at close — released, replaced by the buyer, or structured as a seller indemnification.

Most landlords will demand a personal guarantee from the new owner. If the seller's guarantee is not released at close, the seller remains liable — which can affect their willingness to cooperate with the transaction and create post-close disputes.

Red flag: Landlord insists on both seller and buyer personal guarantees for the remaining term without offering any burn-down schedule, suggesting the landlord has concerns about the gym's operating viability.

Commission an independent review of the rent against current market comparables for comparable retail or fitness-use space in the same submarket.

Below-market rent is a genuine value driver that provides a competitive cost advantage. Above-market rent is a liability that SBA lenders will discount in their underwriting and that creates ongoing margin pressure.

Red flag: Current rent is more than 15–20% above market for comparable fitness-use space, or the next renewal option is at 'fair market value' with no cap — meaning rent could reset dramatically at renewal.

Review the permitted use clause in the lease to confirm it explicitly permits fitness, gym, or health club operations and identify any exclusivity provisions or competing tenant restrictions in the center.

A lease with a narrow permitted use clause (e.g., 'yoga studio only') may restrict you from expanding programming or rebranding. Conversely, an exclusivity clause preventing the landlord from leasing to competing fitness tenants is extremely valuable.

Red flag: Permitted use clause that is narrower than the gym's current service mix, or a shopping center where the landlord has already signed a new fitness tenant in an adjacent space.

Obtain a complete equipment inventory listing every piece of cardio, strength, functional training, and studio equipment including manufacturer, model, serial number, purchase date, and estimated replacement cost.

You cannot underwrite a gym acquisition without knowing exactly what you are buying and what it will cost to replace. This inventory also forms the basis of the asset schedule in the purchase agreement.

Red flag: Seller cannot produce a complete inventory list or purchase records, suggesting informal asset management and likely undisclosed maintenance deferrals.

Hire an independent fitness equipment service technician to physically inspect all cardio machines, assess belt wear, motor condition, and frame integrity, and provide a written condition report with estimated repair and replacement costs.

A treadmill belt replacement costs $150–$300. A motor replacement costs $800–$1,500. Full cardio floor replacement for a 5,000 sq ft gym can run $80,000–$200,000. You need to know what you are inheriting before you negotiate price.

Red flag: More than 25% of cardio equipment is more than 8 years old with no documented service history, or multiple machines with visible damage that the seller has not disclosed in the listing materials.

Review all equipment maintenance and service records for the past 3 years. Confirm whether the gym has a preventive maintenance contract with a commercial equipment service provider.

Regular preventive maintenance extends equipment life and signals an operationally disciplined seller. Gyms without service contracts typically have higher failure rates and larger deferred repair backlogs.

Red flag: No maintenance records exist, or all service was performed by unqualified staff rather than certified commercial equipment technicians.

Assess the HVAC system capacity and condition — gym HVAC runs at significantly higher load than typical retail due to density, body heat, and humidity. Request service records and last inspection report.

HVAC failure in a gym is an immediate operational crisis. A full commercial HVAC replacement for a mid-size gym space can cost $30,000–$80,000 and can take weeks to resolve, causing member attrition during repair.

Red flag: HVAC units that are more than 12 years old with no recent service documentation, or evidence of persistent humidity or air quality complaints in member reviews.

Build a 5-year capital expenditure projection for equipment replacement, HVAC, flooring, locker room fixtures, and technology infrastructure. Use this to stress-test your post-close cash flow model.

SBA lenders will ask for this. More importantly, unexpected capex in years 1–2 post-close can destroy cash flow and default your loan. Knowing the number before you close allows you to negotiate price adjustments or escrow holdbacks.

Red flag: 5-year capex projection exceeds 20% of the purchase price, or the seller has made no capital reinvestment in equipment in the past 3+ years — a clear sign of milking the asset before sale.

Obtain a complete staff roster with role, certification status, tenure, employment type (W-2 vs. 1099), hours, and compensation. Identify all staff whose departure would materially affect member retention.

Many gyms classify personal trainers as independent contractors (1099) when they should legally be W-2 employees. Misclassification creates IRS liability that transfers to the buyer if not caught in due diligence.

Red flag: Personal trainers classified as 1099 contractors who work exclusively at the gym, follow set schedules, and use gym equipment — a classic misclassification pattern that creates back-tax and penalty exposure.

Conduct confidential one-on-one conversations with key staff members — head trainers, class instructors, and the gym manager — to assess their intent to remain post-close and their relationship with the seller.

Key staff departures in the first 90 days post-close are the number-one driver of member attrition beyond the owner's own departure. You need to know whether loyalty is to the gym or to the seller personally.

Red flag: The gym manager or top-revenue trainer has already been approached by competitors, is known to be unhappy, or has made comments to other staff about 'not knowing what will happen after the sale.'

Review all employment contracts, independent contractor agreements, non-solicitation clauses, and non-compete provisions currently in place for all staff.

If key trainers have no non-solicitation agreements, they can legally take their client rosters to a competitor gym the day after you close. This is a common and devastating post-close scenario.

Red flag: No non-solicitation or non-compete agreements exist for any staff, or existing agreements are unenforceable due to overly broad geographic scope or lack of consideration.

Assess staff certifications and confirm they are current. Key certifications include ACE, NASM, NSCA, CrossFit L1/L2, CPR/AED, and any specialty programming credentials (Pilates, TRX, yoga).

Lapsed certifications create liability exposure and, in some states, may violate fitness industry regulations. They also signal a lack of operational discipline that may extend to other compliance areas.

Red flag: More than two trainers with lapsed certifications, or a group class program built around a format (e.g., CrossFit, Les Mills) where the gym's licensing is tied to the seller personally.

Negotiate a seller transition period of 60–180 days post-close during which the seller makes formal introductions to key members, co-leads high-traffic classes, and assists with staff and operational handover.

Member churn spikes most severely in the first 90 days post-close. A structured seller transition plan mitigates this by providing continuity and signaling confidence to the community.

Red flag: Seller is unwilling to commit to any transition period or wants to close and immediately stop all involvement — a major signal that they believe the community is not transferable without them.

Request 3 years of tax returns (business and personal), 3 years of P&L statements, and 24 months of bank statements. Cross-reference all three sources for consistency.

Tax returns represent the floor — what the seller reported to the IRS. P&Ls represent the seller's adjusted view. Bank statements are the ground truth. All three should tell a consistent story; significant divergence demands explanation.

Red flag: Tax returns showing significant losses while the seller claims substantial add-backs, or bank deposits materially inconsistent with both the P&L and the billing platform data — a classic sign of undisclosed cash transactions.

Build a full add-back schedule. Require the seller to document every discretionary, non-recurring, or owner-specific expense with supporting invoices or bank statements. Common gym add-backs include the owner's personal training sessions, family member salaries, personal cell and vehicle expenses, and one-time equipment repairs.

Add-backs directly determine SDE and, therefore, your purchase price. An undocumented add-back is a negotiating fiction. Every add-back must be supported by evidence and must represent a real expense that a new owner would not incur.

Red flag: Add-backs that exceed 25% of EBITDA, add-backs with no supporting documentation, or add-backs that represent revenue the seller claims informally but has never run through the business (i.e., claimed but unprovable cash income).

Verify personal training revenue against trainer session logs, scheduling software records, and client payment histories. Compare against W-2/1099 compensation paid to trainers to validate margin integrity.

Personal training is often the highest-margin revenue line in a gym — but it is also the easiest to overstate. Trainer session logs cross-referenced with payroll costs provide an independent check on reported PT revenue.

Red flag: Personal training revenue that cannot be reconciled with trainer compensation expense, or PT revenue that is disproportionately concentrated in sessions delivered personally by the selling owner.

Review all recurring vendor contracts: cleaning services, music licensing (BMI/ASCAP), equipment leases, software subscriptions (Mindbody, ClubReady, Zen Planner), insurance policies, and any franchise or affiliate fees (CrossFit affiliation, etc.).

These costs transfer to the buyer and must be reflected in your post-close P&L model. Music licensing violations (unlicensed streaming) are also a common compliance issue that creates retroactive liability exposure.

Red flag: Music or content played in group classes without verified ASCAP/BMI licensing, equipment on lease with unfavorable buyout terms, or a CrossFit affiliation fee that is substantially below market — suggesting informal arrangement that may not survive ownership transfer.

Model post-close financials with realistic management replacement cost. If the seller performs any operational role (training, front desk, management), add the market-rate cost of replacing that labor to your pro forma.

Gym SDE figures frequently omit the economic value of the seller's labor. A seller who personally trains 15 clients per week and manages daily operations is providing $80,000–$120,000 of annual labor value that must be replaced at market rates.

Red flag: SDE that requires the buyer to work 50+ hours per week to maintain, or a pro forma that assumes the buyer will personally replace all seller functions without adjusting for realistic labor costs.

Review all member liability waiver forms for enforceability in the state where the gym operates. Waivers must be signed, dated, and retained in a searchable system (paper or digital).

Slip-and-fall injuries, equipment-related injuries, and medical events during training are the primary sources of gym litigation. An unenforceable or missing waiver converts a defensible claim into an expensive settlement.

Red flag: Waivers that have not been updated in more than 5 years, states where pre-injury liability waivers are unenforceable (California, Louisiana, Virginia), or a digital system with no audit trail of waiver execution.

Confirm the gym carries adequate commercial general liability insurance (minimum $1M per occurrence / $2M aggregate), commercial property coverage, and hired/non-owned auto if staff drive for gym purposes. Review loss run reports for the past 5 years.

Loss runs reveal claim history that affects post-close insurability and premium costs. A gym with multiple prior claims may face difficulty obtaining comparable coverage at renewal or may face premium spikes that erode post-close margins.

Red flag: More than two general liability claims in the past 5 years, a gap in coverage at any point in the past 3 years, or insurance coverage that is clearly inadequate for the facility's member count and programming intensity.

Verify business licenses, local health department permits, building occupancy permits, and any state-specific fitness facility licenses are current and transferable to a new owner.

Some states (California, Florida, New York) have specific health club licensing laws that require bonding, pre-sale member disclosures, and contract regulations. Non-compliance creates regulatory liability that transfers to the buyer.

Red flag: Any expired permits, a certificate of occupancy that does not match the current use of the space (e.g., space was converted from retail without a new permit), or a state health club bond that will lapse at ownership transfer.

Review any pending or historical litigation, EEOC complaints, ADA accessibility violations, or labor department investigations involving the gym.

Undisclosed pending litigation is a dealbreaker. ADA violations in gym facilities (accessible entrances, restrooms, and equipment areas) can result in demand letters and remediation costs of $10,000–$100,000+.

Red flag: Any undisclosed litigation revealed during UCC lien searches or through staff interviews, or obvious ADA deficiencies in the facility that the seller has not remediated.
