How to Estimate Rehab Costs Like a Pro

One of the most common mistakes new investors make is underestimating rehab costs. Here is a systematic approach to creating accurate estimates.

The Three Tiers of Rehab

Cosmetic ($10-20/sqft) - Interior and exterior paint - New fixtures and hardware - Carpet/flooring refresh - Minor landscaping - Deep cleaning

Moderate ($25-45/sqft) - Everything in cosmetic, plus: - Kitchen remodel (cabinets, counters, appliances) - Bathroom updates - New flooring throughout - Electrical panel upgrade - Minor plumbing updates

Full Gut ($60-100+/sqft) - Complete interior demolition - New mechanical systems (HVAC, plumbing, electrical) - Structural repairs - Foundation work - Complete kitchen and bath - New windows and doors - Roof replacement if needed

Cost Multipliers

Several factors can increase your base costs: - Property age: Pre-1960 homes add 15-30% for lead paint, asbestos, and outdated systems - Market conditions: Labor shortages can add 10-20% in hot markets - Permits: Budget $2,000-10,000 for permits depending on scope - Contingency: Always add 10-15% for unexpected issues

Pro Tips

1. Get three contractor bids minimum 2. Walk the property with your contractor before making an offer 3. Use a standardized scope of work template 4. Build relationships with reliable subcontractors 5. Factor in holding costs during rehab (mortgage, insurance, utilities)

The difference between successful and struggling investors often comes down to rehab estimation accuracy.
