ARV formula
ARV = renovated comps $/sqft × your square footage. Max offer = ARV × 70% − rehab. Model the refinance instead of selling with the BRRRR calculator.
Frequently asked questions
How do you calculate ARV?
Average the price per square foot of 3–5 renovated comparable sales within a mile and multiply by your property's square footage. Adjust for beds, lot and condition.
What is the 70% rule?
Flippers pay at most 70% of ARV minus rehab costs. The 30% margin covers financing, closing, holding costs and profit.
Is the 70% rule too strict in hot markets?
Experienced flippers sometimes stretch to 75–80% in low-risk, fast-moving markets — but the thinner the margin, the less room for surprises.
