1. Deal Run ($99/month)
Deal Run combines flip analysis with real comp data and AI-powered repair estimates. Enter an address, and the platform pulls comparable sales, estimates repairs from property photos and data, and calculates your projected profit. It also supports rental and BRRRR analysis on the same property, plus investor search for when you need to sell the finished product.
Best for: Investors who want analysis AND disposition in one platform.
2. DealCheck (Free-$29/month)
The most popular standalone deal calculator with a clean mobile app. Analyze flips, rentals, BRRRR, and commercial deals. Comp lookup included on paid plans. Import from MLS or Zillow links. PDF reports for partners or lenders.
Best for: Investors who only need analysis (no buyer finding or marketing). Great mobile app.
Limitation: No skip tracing, no buyer search, no deal marketing. Stops at "is this a good deal?" — does not help you sell it.
3. BiggerPockets Calculator (Free)
BiggerPockets offers free flip, rental, and BRRRR calculators. Basic but functional. All inputs are manual (no comp integration). Good for beginners learning the formulas.
Best for: New investors on a budget who want to practice running numbers.
4. Rehab Valuator (Free-$49/month)
Detailed flip calculator with presentations and reports you can share with lenders or partners. The free version handles basic flip analysis. Paid version adds marketing materials and team features.
Best for: Flippers who need polished deal presentations for private lenders.
5. FlipperForce ($79-$199/month)
Project management platform for flippers with built-in deal analysis, budget tracking, and contractor management. More focused on managing active flips than analyzing potential deals.
Best for: Active flippers managing multiple renovations simultaneously.
6. Spreadsheet (DIY, free)
Many investors use custom Google Sheets or Excel templates. Fully customizable but requires building formulas from scratch and manually inputting all data. See our spreadsheet vs. software comparison.
