Estimating Rehab Costs

Accurate rehab estimates are critical for house flipping, BRRRR investing, and renovation projects. Underestimating costs is the most common reason flips lose money.

Major Cost Categories

  • Kitchen: Typically the most expensive room ($10,000-$40,000)
  • Bathrooms: $5,000-$20,000 per bathroom
  • Flooring: $3-$12 per square foot installed
  • Paint: $2-$5 per square foot (interior and exterior)
  • Roof: $5,000-$15,000 for full replacement
  • HVAC: $3,000-$8,000 for new system

    • Budgeting Tips

  • Always include a 10-20% contingency for surprises
  • Get at least 3 contractor bids for large jobs
  • Permits can add 10-15% to specific trade costs
  • Factor in dumpster rental, storage, and staging
