Buying a Gym: Due Diligence Checklist & Red Flags (2026)

Red flag: High month-over-month churn (>5% for general gyms) or large number of frozen/membership pause accounts without reactivation plans.

Ask: Can I review the last 24 months of billing reports showing gross EFT deposits, breakdown by membership type, and monthly freeze/cancellation counts?

Red flag: More than 30% of total revenue coming from one or two trainers who are independent contractors and could easily leave, or no enforceable non-solicitation agreements.

Ask: What percentage of total gym revenue comes from personal training, and can I see the top three trainers' production and their contractor agreements or employment terms?

Red flag: Large lease payments on cardio equipment that exceed 15% of gross revenue, or lease terms ending within 12 months with significant balloon payments or return conditions that require refurbishment.

Ask: Provide a schedule of all financed or leased equipment, including monthly payment, residual/buyout amount, and maintenance contract terms. Are any pieces under warranty or near end-of-life?

Red flag: Owner adds back 'personal' expenses that are actually necessary operating costs (e.g., 'promotional' expenses, vehicle, meals that are not truly discretionary), inflating SDE by 20%+.

Ask: Walk me through every add-back on the recast P&L. Which expenses will disappear completely upon sale, and which have a business purpose I would need to replace?

Red flag: Gaps in waiver execution for long-term members, or a pattern of slip-and-fall or equipment-injury claims that have caused premium spikes or policy cancellations.

Ask: Can I see copies of the executed waivers for the top 50 members by tenure and the loss-run statements from your general liability insurer for the last three years?

Red flag: Access logs show the gym is consistently empty during advertised staffed hours, or significant tailgating (one fob letting in multiple people) indicating revenue leakage.

Ask: Export the last 12 months of key-fob entry data by timestamp. What is the average daily check-in count and what percentage occurs during staffed vs. unstaffed hours?

Red flag: Cardio machines averaging 7+ years with no repair records, visible rust on strength equipment pins, or multiple 'out of order' signs plastered on machines for weeks.

Ask: Show me the preventive maintenance log and service records for all major equipment over the last 24 months. What is the planned capex for equipment replacement over the next 2 years?

Red flag: Using an outdated, unsupported system or one that does not integrate with modern payment gateways, making it difficult to enforce billing or manage freezes.

Ask: Which gym management platform do you use (e.g., Mindbody, ClubReady, Glofox), and is the data easily exportable? Can you demo the billing freeze, delinquency follow-up, and reporting dashboards?

Red flag: Class schedule is entirely dependent on the owner teaching 20+ sessions per week, or front desk staff have been hired through informal cash payments with no payroll records.

Ask: Who covers classes and personal training sessions if you are gone for a week? Provide a roster of all instructors with hire dates and W-2 or 1099 status.

Red flag: Mold smell in locker rooms, missing tiles, or HVAC units that can't maintain proper humidity, leading to rust on equipment and a reputation for being unclean.

Ask: When was the last HVAC/air-handling unit service, and do you have a dehumidification system in the pool area or locker rooms? I want to visually inspect the ceilings and drain pans for mold.

Red flag: A new big-box gym (Planet Fitness, Crunch, VASA) has opened or is opening within 1 mile offering memberships at half the price, or a boutique studio has siphoned off the high-end training clientele.

Ask: List all competing gyms and boutique studios within a 3-mile radius. Have any opened or announced renovations in the last 12 months? How has your membership count trended since?

Red flag: The trade area's daytime population is shrinking or aging out of the gym's core demographic, and the seller cannot articulate a plan to attract the remaining segment.

Ask: What is the average age and income of your current membership base, and how has that shifted over the last three years? Can I see the last three tax returns' gross receipts to correlate with population changes?

Red flag: Below 4.0 stars with a significant number of recent negative reviews mentioning billing disputes, cleanliness, or broken equipment — indicating systemic issues that will take months of reputation repair.

Ask: Provide a screenshot of your Google Business Profile dashboard showing review velocity and response rate. What is your current monthly website traffic and lead conversion rate?

Red flag: No corporate wellness partnerships, zero revenue from tanning/hydro-massage/spa add-ons, or a pro shop that is dead — signaling the gym is a pure commodity.

Ask: What percentage of memberships come from corporate accounts or group discounts, and what is the annual revenue from tanning, massage chairs, supplements, and any other non-dues sources?

Red flag: Lease requires landlord approval for assignment but the landlord has a reputation for unreasonable refusal or demanding a new 5-year personal guarantee at above-market terms.

Ask: May I see the original lease and all amendments? Is assignment permitted, and can we get a written estoppel certificate from the landlord confirming rent, term, and any outstanding defaults?

Red flag: The gym was grandfathered into a non-conforming use that will be lost upon sale, or ADA bathroom/shower/locker configurations are not compliant, risking a lawsuit.

Ask: Is the current zoning 'fitness center/health club' by right, or does it require a special permit? Provide any recent ADA surveys or modification records.

Red flag: Top trainers are independent contractors with no non-solicit or non-compete, and they have strong personal relationships with members — meaning they can leave and take 40% of the revenue with them.

Ask: Do all trainers earning over $2,000/month have a signed agreement restricting them from soliciting members for a period after departure? Are these agreements enforceable in this state?

Red flag: No public-performance music license, or the gym runs kids' programs without proper parental waivers and background checks for staff, creating liability exposure.

Ask: Show current ASCAP, BMI, and SESAC licensing certificates. If you offer youth programs or daycare, provide the child-injury waiver template and evidence of staff background checks.

Red flag: The seller is the face of the gym and wants to walk away on Day 1 with no transition period, or their personal training clients represent the majority of gym profit and they plan to start a new studio nearby.

Ask: Will you agree to a 30-day full-time transition, plus an additional 60 days of phone/email support? How do you plan to introduce me to key members and trainers, and will you sign a specific non-compete tied to this zip code?

Red flag: Merchant processor account is tied to the seller's personal Social Security number and cannot be transferred, requiring a new underwriting process that could cause billing interruptions.

Ask: Is your payment processing account corporate or personal? What are the early termination fees for your existing supplier contracts (janitorial, laundry, equipment maintenance) if I want to renegotiate?

Red flag: A significant portion of members are on month-to-month verbal agreements with no signed contract, or their written agreements do not have compliant auto-renewal disclosures, making them unenforceable.

Ask: I need to inspect the signed membership agreements for all active members. What percentage have an initial term obligation versus true month-to-month? Are your EFT authorization forms compliant with state law?

Red flag: The gym's Facebook and Instagram accounts are personal profiles of the owner, not a business page, and they refuse to transfer admin rights; or the domain is registered in the owner's personal account with no backup.

Ask: Provide a list of all digital assets (domain registrar, website hosting, CRM, social media admin rights). Can you demonstrate how to transfer ownership to my business entity at closing?
