## 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

计算示例
A 1,500 sqft home needing kitchen ($15K), bathrooms ($10K), flooring ($5K), paint ($4K), plumbing ($2K), electrical ($1.5K), landscaping ($2.5K), other ($3K). 15% contingency.
- Kitchen: $15,000
- Bathrooms: $10,000
- Flooring: $5,000
- Painting: $4,000
- Plumbing: $2,000
- Electrical: $1,500
- Landscaping: $2,500
- Other: $3,000
- Base total: $43,000
- Contingency (15%): $43,000 x 15% = $6,450
- Total rehab budget: $43,000 + $6,450 = $49,450
- Cost per sqft: $49,450 / 1,500 = $32.97/sqft
