    ARV at different comp levels

    Comps are never identical, so pressure-test the value. Each row applies a different price per sqft to your square footage.

    ARV, explained

    What Is ARV

    After Repair Value is what a property will be worth after renovations are complete. Used by investors to determine maximum offer and exit strategy.

    Comp Selection Rules

    Use 3+ recent sales (within 90 days). Same neighborhood (under 1 mile). Similar size (within 20%). Similar condition (renovated to your planned level). Adjust for differences.

    Conservative ARV

    Always use a conservative ARV for offer math. Take the lowest comp, not the average. If math works at conservative ARV, you have margin. If it only works at average, too tight.

    ARV vs Appraisal

    ARV is investor estimate. Lender appraisal is formal valuation by licensed appraiser. They often differ. Refinance loans use appraised value, not your ARV estimate.

    Common questions

    How many comps do I need?

    Minimum 3. Use most recent and most similar. More comps = better estimate.

    How recent should comps be?

    Within 90 days ideal. Up to 6 months acceptable in slow markets. Older comps lose accuracy fast in changing markets.

    Where do I find comps?

    Public records, MLS (with agent), Zillow, Redfin, Realtor.com. Cross-reference at least 2 sources.

    Do I adjust for differences?

    Yes, bigger lots, more bedrooms, garages, finished basements all justify adjustments. Subtract for inferior features, add for superior.

    What's the 70% rule?

    Maximum offer = 70% × ARV minus rehab costs. Built-in 30% margin for profit, holding costs, and risk. Common rule among house flippers.

    Estimates for planning only. ARV depends on the comps you choose and on market conditions at resale, not on what you spend on repairs. Pull recent, nearby, similar sold comps and confirm every figure before you make an offer.
