The After Repair Value (ARV) is the North Star of the BRRRR method. If your ARV is wrong, your entire financial structure collapses.
Most beginners think they need a Realtor to pull “comps” (comparable sales) from the MLS to know what a house is worth. While a professional appraisal is final, you can—and should—know how to estimate ARV yourself before you ever pick up the phone.
Here is the step-by-step framework to calculating ARV from your laptop in 2026.
1. The “Golden Mile” Rule
Location is everything, but in a BRRRR deal, it’s even more specific.
- Stay within 0.5 to 1 mile: Do not cross major highways, rivers, or railroad tracks. Neighborhood vibes change fast.
- Same school district: This is the #1 driver of value for family homes in the US.
2. Find “Sold” Comps, Not “Active” Listings
This is the biggest mistake rookies make. An “Active” listing is just a seller’s dream. A “Sold” price is a market reality.
- Go to Zillow or Redfin and filter by “Sold” in the last 90-180 days.
- If the market is moving fast (like in 2026), stick to the last 90 days.
3. Match the “Bones” (The 15% Variance Rule)
You cannot compare a 2-bedroom bungalow to a 4-bedroom colonial. Your comps must be:
- Square Footage: Within 15% of your target property.
- Bed/Bath Count: Exactly the same if possible (or adjust +$10k/$15k per bedroom).
- Year Built: Within 10-20 years of yours.
4. The “Renovation Mirror”
To find a true ARV, you must look for houses that look exactly like your house will look after the rehab.
- Look for listings with professional photography, granite/quartz countertops, and luxury vinyl plank (LVP) flooring.
- The Math: Take the average price per square foot ($/sqft) of the 3 best renovated comps and multiply it by your house’s square footage.
ARV Formula:
Average $/sqft of Renovated Comps × Your Property Sqft = Your Estimated ARV
⚠️ The “Zestimate” Trap
Never, ever use the Zestimate or Redfin Estimate as your ARV. These algorithms don’t know if a house has gold-plated faucets or a hole in the roof. They use averages.
In a BRRRR deal, an error of 5% in your ARV can trap $15,000 of your cash in the deal forever.

5. Adjust for Market Trends
In 2026, interest rates are the “invisible hand.”
- If rates are rising: Subtract 3-5% from your estimated ARV as a safety buffer.
- If inventory is record-low: You might be able to lean towards the higher end of your comps.
The “Stress Test” Strategy
Before making an offer, calculate three ARV scenarios:
- Conservative: The lowest renovated comp.
- Realistic: The average of the best 3 comps.
- Aggressive: The highest comp in the area.
If your BRRRR deal only works in the “Aggressive” scenario, walk away.
Conclusion
Estimating ARV is a skill that gets sharper with every deal. Once you have your realistic ARV, the rest is just math.
Don’t let a bad estimate kill your “Repeat” step. Plug your ARV, Purchase Price, and Rehab costs into BRRRR Metrics right now and see if the deal actually pencils out.
