Frequently Asked Questions
How long should due diligence take for a car wash?
Due diligence timelines vary based on transaction complexity, financing requirements, and deal structure. Most car wash acquisitions allow 30-45 days for due diligence, though environmental review or complex financing situations may require longer periods. Buyers should negotiate adequate time in the purchase agreement.
Should I hire a professional inspector for a car wash?
Yes, professional inspection is recommended for major equipment and building systems. Car wash equipment specialists can assess tunnel systems, pumps, and specialized equipment. Building inspectors evaluate structure, roof, electrical, and plumbing. Environmental professionals conduct Phase I/II assessments when required.
What financial documents should I request?
Request 3 years of tax returns, profit and loss statements, balance sheets, and bank statements. Also request POS reports, membership records, utility bills, equipment maintenance records, lease agreements, and any existing appraisals or environmental reports. Organized sellers will have these readily available.
How do I verify membership revenue is accurate?
Verify membership revenue by comparing reported figures to POS system data, bank deposits, and membership management system reports. Request current membership lists and contact the software provider to verify active subscriptions. Review churn rates and member aging reports to assess revenue sustainability.
What environmental issues should I be concerned about?
Common concerns include historical underground storage tanks, chemical storage practices, wastewater discharge systems, drainage issues, and site history. Phase I environmental assessments identify potential concerns and typically determine whether Phase II investigation is needed. Lenders usually require Phase I for financed transactions.
How do I assess equipment condition?
Review maintenance records, interview operators about known issues, and hire equipment specialists to inspect major systems. Document equipment age, condition, and expected remaining useful life. Get cost estimates for any repairs or replacements identified. This information becomes negotiating leverage if issues are found.
Should I review employee records during due diligence?
Employment practices review during due diligence may include verifying employee classifications, reviewing compensation structures, understanding key employee roles, and assessing any labor issues. However, detailed personnel file review typically occurs closer to closing and involves employment law considerations. Discuss scope with your attorney.
What lease terms should I focus on during review?
Key lease provisions include remaining term, renewal options, rent amount and escalation clauses, assignment provisions, use restrictions, maintenance responsibilities, and landlord consent requirements. Understanding these terms helps assess business value, risk, and whether assumptions about future operations are valid.
