How to Estimate ARV Like a Pro Using Real Data (Not Guesswork)
If you want to know "how to calculate ARV," you first have to understand that it is science, not art. Get the ARV wrong, and your flip is doomed from day one.
The After Repair Value (ARV) represents what a property will realistically sell for once it is fully renovated to standard market conditions. Inexperienced flippers often look at the highest priced house in a neighborhood and assume that is their ARV. This is incredibly dangerous.
Rule 1: Use Only 'Sold' Data
Active listings show what sellers *want*, not what buyers are willing to pay. Pending listings are helpful, but sold listings (within the last 3-6 months) are the only absolute truth. If the market is shifting fast, prioritize comps from the last 90 days.
Rule 2: Stay Within the Neighborhood Boundaries
Crossing a major highway, a railroad track, or entering a different school district can shift house values by $50,000+. Keep your comps within a 0.5 to 1-mile radius from your subject property, and respect hard geographical boundaries.
Rule 3: Match the Specs (Apples to Apples)
Your comps must match your subject property. Compare 3 bed/2 baths to other 3 bed/2 baths. Do not compare a 1,200 sqft ranch to a 2,500 sqft two-story colonial. Try to stay within a 15-20% variance in square footage.
Rule 4: Compare Condition
You cannot use a newly constructed house as a comp for a 1970s house you simply put lipstick on. Your target comps should represent the level of finish you plan to provide. If your comp has luxury appliances and a pool, ensure you adjust the value down if your subject property lacks these.
Rule 5: The Appraisal Approach
Once you are under contract with a retail buyer, a bank appraiser will verify your price. Think exactly like an appraiser. Use the exact same metrics they do so there are no surprises at closing.
