How to Calculate After-Repair Value (ARV) for an Oklahoma Flip
Every flip offer starts with one number: what the house will be worth once it is finished. Get it wrong and the rest of the math is fiction.
What ARV actually means
After-repair value (ARV) is the price a renovated house should sell for in the current market. It is an estimate of a future sale, which is why it is the number investors argue about most. A flipper who overestimates ARV by a few percent can erase the entire profit on a project.
Step 1: Choose comparable sales
A comparable sale (comp) is a recently closed sale of a similar house nearby. Good comps share as many of these traits as possible with the house you are valuing:
- Location. Same subdivision or the same few blocks first. Widen the search only when you run out of sales.
- Size. Living area within roughly 10 to 15 percent, the same bedroom and bathroom count, and a similar garage.
- Age and style. A 1960s ranch should be compared to other 1960s ranches, not to a 2005 two-story down the road.
- Condition. This is the one that matters for a flip. You want comps that are renovated to the level you plan to finish at, not distressed sales and not untouched originals.
- Timing. Closed within about the last six months, sooner when the market is moving.
Step 2: Use closed sales, not asking prices
A listing price is a seller's hope. A closed sale price is what a buyer actually paid. Active and pending listings are useful for judging competition, but only closed sales belong in the ARV. If renovated homes in the neighborhood sit on the market for months and sell below asking, the closed prices tell you that and the asking prices hide it.
Step 3: Adjust for differences
No comp is identical. Appraisers adjust each comp up or down for differences such as an extra bathroom, a larger lot, a garage, or a newer roof. You can do the same on a simple scale, then compare the adjusted figures. The comps that need the fewest adjustments deserve the most weight. If one comp needs large adjustments to look like your house, it is probably the wrong comp.
Step 4: Check it against the street
Older Oklahoma City neighborhoods are uneven. Two blocks can separate very different price points, and school boundaries can sit on an unexpected line. A citywide average will mislead you. The best check is to ask: if a buyer walked through this finished house and the nearest comparable sold house, which would they choose, and at what price difference?
Common ARV mistakes
- Comping to the best house, not the typical one. One unusually high sale is an outlier until a second sale confirms it.
- Using unrenovated comps for a renovated house, or the reverse. Condition is a real value driver, so compare like with like.
- Ignoring the neighborhood ceiling. Every street has a price a house cannot exceed no matter how nice the finish. Over-improving a modest house for its street is a classic flip loss.
- Counting on a market that is still rising. Build the deal so it still works if the finished house sells for a little less than you hoped.
Where ARV fits in a deal
Once you have a defensible ARV, the rest of the analysis works backward from it: subtract the rehab budget, holding costs, and selling costs, and decide how much margin you need for the risk. See our guide to the 70% rule for one common shortcut and where it stops working.
