Whole-House Rehab Cost Calculator

Build a whole-house rehab planning range from square footage, renovation depth, property age, major work packages, market level, and contingency.

Choose cosmetic, moderate, or full-gut core scope Add kitchens, bathrooms, roof, HVAC, electrical, plumbing, windows, or structural work separately Adjust for property age and market cost level Keep contingency visible instead of burying it in the rate
Whole-house planning modelStart with core rehab depth, then add only the major systems you expect to touch.

This prevents a kitchen, bathroom, roof or systems package from being silently counted twice inside one giant square-foot rate.

How to use this whole house rehab cost calculator

A useful whole-house estimate should not hide kitchens, bathrooms, major systems, and structural work inside one square-foot rate. This model prices a core renovation allowance first, then adds only the major packages you select.

How this planning model works

The estimate is built from separate scope categories rather than one headline average. That makes it easier to see which selections and trade decisions are moving the range.

The figures are planning allowances, not contractor quotations. Local labor, permits, access, existing conditions, exact specifications, and contractor availability can materially change a real bid.

Why show a range instead of one number?

Early renovation inputs are uncertain. A low-to-high range keeps that uncertainty visible while the working budget gives you a practical middle point plus the contingency you selected.
