The $500K SDE Search: A Realistic Roadmap for Solo Buyers

$500K SDE is the gravitational center of solo acquisition. It's large enough to pay you a real salary post-close, small enough that search funds and PE firms ignore it, and common enough in established HVAC, plumbing, and pest control markets that you can actually find deals.

The math that matters

At 3.0x–3.5x SDE, a $500K SDE business costs $1.5M–$1.75M. With SBA financing at 10% down, you need $150K–$175K cash plus $50K–$75K for working capital, legal, and QoE. Total capital requirement: roughly $225K–$250K. That's achievable for a corporate professional who's saved aggressively for 3–5 years.

A realistic 12-month timeline

1. Months 1–2: Pick trade + metro. Build target list of 75–100 operators. Learn licensing requirements.
2. Months 3–5: Outreach wave 1. Goal: 8–12 owner conversations, 2–3 site visits.
3. Months 6–8: Outreach wave 2 + re-engage warm leads. Goal: 1–2 businesses in serious discussion.
4. Months 9–10: LOI, exclusivity, QoE, SBA application.
5. Months 11–12: Close, transition, first 90 days as operator.

This timeline assumes 10–15 hours per week. Full-time searchers compress it to 6–8 months. Part-time searchers at 5 hours/week should expect 18 months. Both are normal.

Where $500K SDE businesses actually live

• HVAC contractors in Sun Belt metros (15–25 trucks, owner-operated for 20+ years).
• Commercial cleaning companies with 30–50 recurring contracts.
• Pest control operators with route density in suburban corridors.
• Multi-location laundromats with absentee ownership (different playbook — see Passive Assets cluster).

When to walk away

Walk away if: customer concentration exceeds 30%, the owner is the only licensed technician, equipment is leased with personal guarantees you can't assume, or revenue dropped more than 15% year-over-year without a clear explanation. Discipline in the search phase saves you from a disaster in year one.
