Best ARV & Repair Estimator Tools for Investors 2026
Calculating After Repair Value (ARV) accurately is the difference between a profitable deal and a costly mistake. Overestimate ARV by 10% and your flip that was supposed to make $40K suddenly breaks even. Underestimate it and you'll submit offers too low to get accepted. Here are the best tools for calculating ARV in 2026, from AI-powered automation to free manual methods.

1. Deal Run — $99/month
Best for: Investors who want comp analysis, rental analysis, and repair estimation in one tool with AI automation.
Deal Run's comp analysis pulls comparables from both MLS and public records, then scores each comp using AI that evaluates distance, size match, age, condition level, and recency. Instead of manually selecting and adjusting comps, the system presents a ranked list of the most relevant comparables with similarity scores. You can filter by distance, date, property type, and price range, and manually select or deselect comps to fine-tune your ARV.
What makes Deal Run unique in the ARV space is the combination of comp analysis with AI repair estimation (photo-based) and disposition tools. You calculate ARV, estimate repairs, determine your MAO, find buyers, and build a marketing package all in the same platform. The AI condition scoring has a median absolute error of 3.28%, which is competitive with professional appraisals.
Deal Run also pulls rental comps alongside sale comps, so you can evaluate ARR for landlord buyers in the same workflow. This dual analysis is essential for marketing deals to both flippers and rental investors.
Pros: MLS + public records data. AI comp scoring. Rental comps included. Repair estimation. Full disposition workflow. $99/mo includes everything.
Cons: Newer platform. AI scoring is automated -- experienced investors may want more manual control (which is available via the comp grid).
2. PropStream — $99/month
Best for: Property data with basic comp analysis as part of a broader data subscription.
PropStream provides comparable sales data pulled from public records. You can search for sold properties near your subject and view the basic details (address, sold price, date, beds/baths, sqft). The data is helpful but less detailed than MLS data -- you don't get listing photos, days on market, or agent remarks that help assess condition.
PropStream's strength is breadth of data. It covers nationwide property records, tax data, pre-foreclosure, and ownership information. Comp analysis is one feature among many rather than the primary focus. There's no AI scoring, no condition assessment, and no rental comp analysis.
Pros: Nationwide property data. Good for basic comp lookup alongside other property research. Reasonable price.
Cons: Public records only (no MLS data). No AI scoring or condition assessment. No rental comps. Comp selection is entirely manual. No repair estimation or deal analysis built in.
3. Privy — $197/month
Best for: Investors with MLS access who want a dedicated comp analysis platform.
Privy connects directly to MLS data and provides comp analysis with MLS-quality detail (photos, DOM, listing remarks). The platform can identify recently renovated properties, which is useful for finding post-renovation comps. Privy also shows investment metrics like cash-on-cash return and cap rate for rental analysis.
The main drawback is price ($197/mo) and the fact that it requires MLS access in your area. Privy doesn't include skip tracing, buyer identification, marketing packages, or any other disposition features. It's a pure analysis tool.
Pros: MLS data quality. Good at identifying renovated comps. Investment metrics.
Cons: $197/mo for comp analysis only. Requires MLS access. No disposition features. No AI scoring. No repair estimation.
4. DealCheck — $10-$50/month
Best for: Quick deal analysis with manual comp input. Good for beginners learning the math.
DealCheck is a deal analysis calculator, not a comp data platform. You manually input the ARV, repair cost, and other deal parameters, and it calculates returns for flip, rental, BRRRR, and wholesale strategies. It doesn't pull comp data for you -- you need to find comps elsewhere and enter the ARV yourself.
For learning the math of real estate analysis, DealCheck is excellent and cheap. For efficiently analyzing multiple deals per day, the manual data entry becomes the bottleneck. It's a calculator, not a data tool.
Pros: Cheap. Clean interface. Good analysis templates for multiple strategies. Educational for beginners.
Cons: No comp data -- you input everything manually. No AI. No buyer identification or disposition features. Becomes tedious at volume.
5. BiggerPockets Calculators — Free
Best for: Free analysis tools for casual investors. Limited to basic calculations.
BiggerPockets offers free and paid calculators for rental properties, flips, BRRRR, and wholesaling. Like DealCheck, these are calculators that require you to input your own ARV and repair numbers. The free tier has limitations on the number of reports you can run. The analysis templates are solid but basic.
Pros: Free (basic). Well-known brand. Good for learning. Shareable reports.
Cons: No comp data. Manual input only. Free tier is limited. No disposition features. No AI.
6. Manual MLS method — Free (with access)
Best for: Licensed agents or investors with MLS access who want full control over comp selection.
The traditional method: log into the MLS, search for sold comps within your criteria (distance, date, size, type), review each one for condition match, make manual adjustments, and average the results. This produces the most thorough analysis when done by an experienced person, because no AI can fully replace human judgment on condition, neighborhood dynamics, and renovation quality.
The downside is time. A thorough manual comp analysis takes 30-60 minutes per property. At 5+ deals per week, that's 2.5-5 hours just on comp analysis. Tools that automate the initial comp pull and scoring let you focus your time on judgment calls rather than data collection.
Pros: Full MLS data quality. Maximum control. Free if you already have access.
Cons: Requires MLS access (real estate license). Time-intensive (30-60 min per property). No automation. No integration with disposition tools.
The bottom line
The best ARV tool depends on your workflow and what other tools you're already using. If you need comp analysis as part of a complete disposition platform, Deal Run gives you the most value at $99/mo. If you just need a quick calculator and already have comp data from elsewhere, DealCheck at $10/mo or BiggerPockets for free will do the math. And if you have MLS access and the time, the manual method is still the gold standard for accuracy.
