How to Estimate Repair, Rehab, and Renovation Costs for Any Project

How to Estimate Repair, Rehab, and Renovation Costs for Any Project

Estimating rehab costs can be tricky as every project is unique. However, with the right approach and resources, you can get a good idea of what to expect. Here's a guide to help you figure out repair, rehab, and renovation costs for any property.

Ways to Estimate Costs

1. General Contractor Walk-Through

A seasoned general contractor (GC) can walk the property and give you a rough estimate of the necessary repairs. They have the experience to quickly identify potential issues and provide a ballpark figure.

2. Home Inspector Report

Hire a licensed home inspector to identify needed repairs and deficiencies. While they won't provide cost estimates, their report is a great starting point for your budget.

3. Square Footage Cost

Calculate the cost per square foot for the entire project or for specific trades like tile installation or drywall. Over time, you'll develop a reliable cost estimate for these trades based on past projects.

4. Online Calculators

Use online calculators to get a rough estimate of renovation costs. While they can't account for regional price variations or sudden economic changes, they can be helpful in putting together a well-priced scope of work.

5. Ask Friends for Help

Reach out to friends who have recently completed remodels or have construction experience. They can provide valuable insights and price ranges based on their projects.

Who to Work With

General Contractors

Working with a veteran GC is the safest option, especially for large projects. Their experience allows them to provide semi-accurate estimates quickly. However, keep in mind that even experienced contractors can sometimes be off in their estimates.

Home Inspectors

Home inspectors can provide a detailed list of repairs but won't give you cost estimates. Use their report to research prices online and create your budget.

How to Calculate Costs

Use the following methods to calculate costs for additional improvements:

Develop a Square Footage Cost

Track costs for each trade as you complete projects. For example, if your tile contractor consistently charges $5 per square foot, use that figure for future estimates.

Online Resources

Use the internet to attach prices to items listed in the home inspector's report. This approach is sensible and relatively safe.

Contact Subcontractors

Reach out to subcontractors to get square footage prices for their work. Some may be willing to provide this information, while others may not.

Customize Your Approach

Different projects require different approaches:

Major Remodels

For large projects involving major structural changes, hire a GC to walk the site and provide an estimate. Accuracy is crucial for high-cost projects to ensure profitability.

Moderate Updates

For homes needing updates like a new kitchen, bathrooms, flooring, and paint, consider contacting subcontractors directly for pricing on each trade.

Small Projects

For small jobs requiring minor updates, measure carefully and shop for materials yourself. Include all costs like taxes, delivery, and installation.

Regional Price Variations

Keep in mind that prices vary greatly by region. Costs in major cities like San Francisco or New York can differ significantly from smaller cities.

Final Thoughts

The more experience you gain, the better you'll become at estimating costs. While mistakes can be costly, the ability to accurately estimate construction costs will set you apart from your competition and increase your profitability. There's a lot of money to be made in fixing up distressed properties, so invest your time and effort to master this skill.
