Per-square-foot cost is the fastest way to ballpark a rehab. "It's a 1,400 sqft house that needs a moderate rehab. $35-$50 per foot. That's $49,000-$70,000." You can do that math while driving past the property. Here's how to calibrate your numbers.
The Benchmarks
These are starting points. Your market will vary.
Cosmetic Refresh ($15-$25/sqft) Paint, new flooring, updated fixtures, minor repairs. No structural. No system changes. Kitchen gets hardware and countertop at most. Bathrooms get new fixtures.
A 1,400 sqft cosmetic: $21,000-$35,000
Moderate Rehab ($30-$50/sqft) New kitchen, updated bathrooms, new flooring throughout, paint, possible selective system updates (panel upgrade, partial re-pipe). Some drywall work.
A 1,400 sqft moderate: $42,000-$70,000
Full Gut ($60-$100/sqft) Down to studs. New electrical, new plumbing, new HVAC, new drywall, new everything. Possibly structural modifications.
A 1,400 sqft full gut: $84,000-$140,000
Calibrating for Your Market
National benchmarks are useless without local calibration. Here's how to build accurate per-sqft numbers for your area:
- Track your actual costs on every completed project
- Divide total rehab cost by square footage
- Categorize by scope level (cosmetic, moderate, full)
- After 3-5 projects, you'll have reliable per-sqft ranges for your market
Until you have your own data, use these benchmarks as a starting point and verify with local contractors and fellow investors.
When Per-Sqft Breaks Down
Per-sqft estimation is great for quick deal analysis but fails when:
- Kitchens and bathrooms are disproportionate. A 1,000 sqft house with 3 bathrooms costs more per foot than a 1,000 sqft house with 1 bathroom.
- Basements are included. Unfinished basements inflate sqft without proportional cost.
- The house has unusual features. A house with a pool, detached garage, or complex roofline breaks the per-sqft model.
- Systems need replacement. An HVAC replacement is a fixed cost regardless of sqft.
Use per-sqft for initial screening. Use a detailed scope for actual budgeting.
The Two-Step Method
Step 1: Per-sqft estimate for deal screening. "This 1,400 sqft house needs a moderate rehab. Roughly $42K-$70K. Does the deal work at $55K rehab cost?" If yes, move to step 2. If no, pass.
Step 2: Detailed scope for actual budgeting. Book a scope visit. Get line-item detail. Know the real number before committing.
