## Executive Summary & Unmet Pain Point
- **Summary**: Underwrite membership recurring revenue, water/electric utility-to-gross-revenue ratios, equipment depreciation, and SBA 7(a)/504 DSCR (>=1.30x) for car wash and laundromat acquisitions.
- **Unmet Pain Point**: Buyers get rejected by SBA credit committees when seller tax returns underreport cash revenue and fail to verify water-meter gallon-per-turn utility audits.
