How to Calculate ARV: Complete Guide
After-repair value (ARV) is the estimated market value of a property after all renovations are complete. It is the single most important number in any flip or wholesale deal analysis because every other calculation flows from it. Your maximum purchase price, your profit margin, your buyer's offer, and your assignment fee all depend on an accurate ARV. Get it right and you make money. Get it wrong and everything else falls apart.
What ARV actually represents
ARV answers one question: "What will this property sell for after it is fully renovated to match the best comparable homes in the neighborhood?" It is not a theoretical value. It is grounded in real data: actual sale prices of similar, renovated properties that have recently closed in the same area. For an overview of how ARV relates to other valuation metrics, see our ARV vs. ARR guide.
The 5-step ARV calculation process
Step 1: Define your subject property after renovation
Before pulling comps, determine what the property will look like after your renovation. If you are turning a dated 3-bed/2-bath into a modern 3-bed/2-bath with new kitchen, bathrooms, flooring, and paint, then your comps should be modern, renovated 3-bed/2-bath homes. If you are adding a bedroom or bathroom, adjust accordingly.
Key attributes to match:
- Bedrooms and bathrooms (exact match preferred, +/- 1 acceptable)
- Square footage (within 20% of subject)
- Property type (single-family vs. townhome vs. condo)
- Condition after renovation (renovated, not distressed)
- Style and age range (similar era construction)
Step 2: Pull comparable sales
Search for recently sold properties that match your post-renovation subject. The ideal comps are:
- Within 0.5 miles of the subject property. In dense urban areas, 0.25 miles may be appropriate. In rural areas, you may need to expand to 1-2 miles.
- Sold within the last 6 months. Older sales reflect a different market. In rapidly appreciating markets, even 3-month-old sales may understate current value.
- Similar in size, bedrooms, bathrooms, and condition. Renovated properties should be compared to renovated properties.
- In the same school district if the area is family-oriented.
- On the same side of major boundaries (highways, railroad tracks, rivers) that create neighborhood divisions.
Pull 5-10 potential comps. You will narrow down to the best 3-5 after review. For detailed comp pulling techniques, see our comps guide.
Step 3: Adjust each comp
No two properties are identical. Adjust each comp's sale price to account for differences from your subject property. Standard adjustments:
| Difference | Adjustment | Direction |
|---|---|---|
| Square footage | $20-$40/sqft | Add if comp is smaller, subtract if larger |
| Extra bedroom | $5,000-$15,000 | Add if comp has fewer, subtract if more |
| Extra bathroom | $5,000-$10,000 | Add if comp has fewer, subtract if more |
| Garage (2-car vs. none) | $10,000-$25,000 | Add if comp lacks garage |
| Pool | $5,000-$15,000 | Market-dependent |
| Lot size (significant difference) | $5,000-$20,000 | Add if comp has smaller lot |
| Age difference (10+ years) | $3,000-$10,000 | Add if comp is older |
| Condition (superior finish) | $5,000-$15,000 | Subtract if comp has better finish |
Adjustments should never exceed 25% of the comp's sale price. If you need more than 25% adjustment, the comp is not comparable enough. Discard it and find a better one. See our comp adjustment guide.
Step 4: Calculate the ARV
After adjusting all comps, take the median of the adjusted values (not the average). The median is less affected by outliers and gives a more reliable estimate.
Example with 4 adjusted comps:
Comp A adjusted: $188,000
Comp B adjusted: $195,000
Comp C adjusted: $192,000
Comp D adjusted: $205,000
Median: ($192,000 + $195,000) / 2 = $193,500
Conservative ARV: $192,000 (round down to nearest $1,000)
Always round down, not up. Being conservative on ARV protects your profit margin on every deal.
Step 5: Validate against active listings
Cross-check your ARV against currently active listings of comparable properties. If three renovated homes similar to yours are listed at $185,000-$195,000, your $192,000 ARV is well-supported. If the only similar listings are at $175,000, your ARV may be too optimistic.
Active listings represent the ceiling of what buyers are currently being asked to pay. Your ARV should be at or slightly below the average active listing price for comparable properties.
Common ARV mistakes
Cherry-picking the highest comp. Using one outlier sale to justify a high ARV is the most common and most expensive mistake. Use the median of multiple comps.
Using non-renovated comps. If your subject will be fully renovated, do not use sales of unrenovated properties. The condition difference is too large to adjust for accurately.
Ignoring market direction. If prices have been declining for 3 months, a sale from 6 months ago may overstate current value. Weight recent sales more heavily.
Crossing neighborhood boundaries. A comp from across the highway, railroad tracks, or school district boundary may be in a completely different micro-market despite being geographically close.
Insufficient comps. One or two comps is not enough. Market flukes (estate sale, divorce, cash deal with concessions) can make individual sales misleading. Use at least 3 comps, preferably 4-5.
Using ARV in deal analysis
Once you have your ARV, it drives every other calculation:
Maximum purchase price (flip): ARV × 70% − repairs. See 70% rule guide.
Maximum purchase price (wholesale): ARV × 70% − repairs − your assignment fee. See MAO guide.
Projected profit (flip): ARV − purchase − repairs − holding costs − selling costs. See flip calculator guide.
Every investor who buys your deal will independently verify the ARV. If your numbers are inflated, buyers will pass. If your ARV is conservative and well-supported by comps, buyers will trust your deal packages and close faster.
