The Complete House Flipping Software Stack (2026)

Serious house flippers rely on a combination of: lead generation software (PropStream, DealMachine) to find distressed properties, rehab estimating software to scope repair costs room-by-room, ARV calculators to determine after-repair value from comps, and deal analysis software to model full profit projections. Many investors use free web-based calculators like those at RealEstateStackHub for the math layer before committing to paid platforms.

ARV stands for After-Repair Value — the estimated market value of a property after all planned renovations are complete. It is the cornerstone number in any flip analysis. Your maximum allowable offer (MAO) is typically ARV × 70% minus estimated repair costs. An accurate ARV requires recent comparable sales within 0.5–1 mile, similar square footage and condition, sold within the last 90–180 days. Use our free ARV Calculator to weight and adjust comps.

Flip profit = ARV − (purchase price + rehab costs + holding costs + selling costs). Holding costs include mortgage interest, taxes, insurance, and utilities for the renovation period. Selling costs include agent commissions (5–6%) and closing costs (1–2%). A healthy flip targets 15–20% net profit margin on ARV. Use the Flip Profit Calculator to model all variables with one form.

The 70% rule is a quick screening heuristic: MAO = (ARV × 0.70) − Repair Costs. For a home with $250,000 ARV and $40,000 in repairs: MAO = ($175,000) − $40,000 = $135,000. Deals above this price need scrutiny — the margin compresses fast when costs overrun or the market softens. Use it as a filter, not a substitute for full deal analysis.

Real estate rehab software estimates repair costs before you buy a distressed property. Good house rehab software breaks costs by trade (electrical, plumbing, HVAC, roofing, flooring) and room, applies local labor rate benchmarks, and generates a scope-of-work estimate for contractors and lenders. RealEstateStackHub's Rehab Cost Estimator covers 13 room types with city-specific benchmarks across 60+ US markets.

RealEstateStackHub provides a free suite: Rehab Cost Estimator (13 rooms, 60+ cities), Flip Profit Calculator (8 metrics, MAO/break-even), ARV Calculator, and Deal Analyzer (full 10-year pro forma, 7 data sources). No account required. All tools run entirely in-browser with sub-2-second load times.
