What this calculator measures

Checks your purchase price against the 70% rule to ensure margin.
Calculates ROI and annualized ROI based on hold period.
The 70% rule explained
Max purchase price = (ARV × 70%) − Rehab Costs.
This leaves ~30% margin for profit, holding costs, and sale costs.
Conservative flippers use 65%, aggressive markets may go to 75%, but rarely higher.
Critical inputs
ARV: use conservative comps — optimistic ARV is the #1 reason flips fail.
Rehab costs: add 10-20% buffer for unknowns.
Holding period: longer holds = higher costs (interest, taxes, utilities).
Sale closing costs: typically 8-10% (6% realtor, 2-4% closing/transfer).
What makes a good flip
Net profit ≥ $30K-$50K minimum (worth your time and risk).
Follows 70% rule with conservative ARV and rehab.
Hold period ≤ 6 months (less carry cost risk).
Annualized ROI ≥ 20-30%+.
Common mistakes
Underestimating rehab — always add a buffer.
Overestimating ARV — use sold comps, not active listings.
Ignoring holding costs — they add up fast on longer projects.
Paying above 70% rule without solid justification.
