Know exactly what the calculator is doing.
Rehab budget = area allowance + kitchens + bathrooms + systems + exterior + permits + contingencyPer-square-foot allowances are only a screening device. Separate large systems and room-specific work so they are not hidden inside one blended rate.
Use the result as a decision aid, not a verdict.
Measure the work
Record rooms, quantities, dimensions, assemblies, and observed conditions.
Separate uncertain systems
Do not bury roof, foundation, electrical, or plumbing risk in a cosmetic square-foot rate.
Replace allowances with evidence
Update the starting budget with written bids, selections, permit research, and verified quantities.
What this calculation cannot know.
- Regional labor and material prices vary materially.
- Hazardous materials, structural defects, concealed damage, and code upgrades require qualified review.
- Contingency is not a substitute for a complete scope.

Understand the terms before using the output.
How accurate is a rehab cost calculator?
It is a screening estimate. Accuracy improves when quantities, specifications, local pricing, and contractor bids replace allowances.
What should cost per square foot include?
Define it explicitly. This calculator treats it as general interior work and keeps kitchens, bathrooms, systems, exterior work, and permits separate.
How much contingency should I use?
Use a project-specific reserve based on scope completeness and uncertainty. A cosmetic project with verified conditions may need less than a structural renovation with limited access.
Should permits be included?
Yes. Include known permit, design, engineering, testing, and inspection-related costs when applicable.
Can I download a repair budget template?
Yes. The Rehabfolio investor toolkit includes a formula-driven rehab budget and scope-of-work workbook.
