Understanding ARV & the 70% Rule
ARV (After Repair Value) is what the property will be worth once fully renovated, based on comparable sold properties nearby.
MAO = (ARV × 70%) − Rehab Costs
Example: ($300k × 70%) − $45k = $165k max offer
Example: ($300k × 70%) − $45k = $165k max offer
The 30% buffer covers: selling costs (~8%), holding costs, profit margin (~15%), and contingency. Adjust the factor based on your market and target return.
Frequently Asked Questions
How do I find accurate comps?
Use recently sold properties (last 3–6 months) within 1 mile of your subject property, similar in size (±20%), bed/bath, age, and condition. Sources: MLS, Zillow "sold" filter, Redfin, or public county records. Always use post-renovation comps — you need properties that sold in renovated condition.
Should I always use 70%?
No. The 70% rule is a starting point. In hot markets with fast turns and low holding costs, experienced flippers may go to 75–80%. In slow markets or for large rehabs, 60–65% may be more appropriate. The key is that your rule factor must account for all costs and still produce your target profit.
What costs does the 30% buffer need to cover?
The 30% left over from the 70% rule should cover: purchase closing costs (2–3%), holding costs (taxes, insurance, utilities), selling costs (agent commissions + closing = 8–10%), financing costs (if using hard money), and your profit target (typically 10–20% of ARV).
