The 70% Rule Explained: How to Calculate Maximum Purchase Price
The 70% rule is the most widely used formula in fix-and-flip investing. Learn how it works, when to use it, and when to break it.
From acquisition to sale, follow the complete lifecycle of a profitable flip and learn what makes each phase successful.
A successful fix-and-flip project follows a predictable lifecycle with five distinct phases: acquisition, planning, renovation, marketing, and sale. Excellence in each phase compounds to produce consistent profits.
Phase 1 — Acquisition (Weeks 1–2): The deal is won or lost here. Conduct thorough due diligence: verify ARV with 5+ recent comps, get contractor estimates for the renovation (or use your per-square-foot cost database), confirm title is clear, check for liens and code violations, and negotiate terms that give you adequate margin. Close quickly — sellers choose speed and certainty over a marginally higher price.
Phase 2 — Planning (Week 2–3): Before any demolition begins, create a detailed scope of work, material selections, and project timeline. Submit permit applications, order long-lead-time materials (custom cabinets, special-order windows), and schedule subcontractors. A week of planning saves two weeks of execution.
Phase 3 — Renovation (Weeks 3–10): Execute the scope of work in the proper sequence: demolition, structural, rough-ins (electrical, plumbing, HVAC), insulation, drywall, finish carpentry, painting, flooring, fixtures, and landscaping. Inspect work daily, document progress with photos, and manage your budget against actuals weekly.
Phase 4 — Marketing (Weeks 8–11): Begin marketing before renovation is complete. Professional photography, virtual staging, targeted social media ads, and MLS listing should be coordinated to launch within days of project completion. Price based on your comp analysis, not your cost basis.
Phase 5 — Sale (Weeks 11–16): Manage showings, negotiate offers, and navigate the closing process. Have your next deal lined up so capital isn't sitting idle between projects.
