Learning to estimate rehab costs

[Michael Storch]

Hello BP members,

I am new to REI and have only read a couple books on the topic. Are there any ways that would be recommended to learn to estimate rehab costs better? Obviously this will come with experience, but initial education can ease some growing pains.

Thanks!

Hey Michael,

So here is the process that I generally recommend for people trying to learn how to estimate repair costs. 

Unfortunately, it isn't easy and takes time, but it is the best way to develop the foundational knowledge of construction and estimating costs:

#1 Read the Book on Estimating Rehab Costs

JScott's 'The Book on Estimating Rehab Costs' is a great resource for new rehabbers to learn how to Estimate Repair Costs on 25 common rehab repairs.

#2 Explore Lowes and Home Depot to Learn About Material Pricing

Take a tour through Lowes and Home Depot (or their websites) and look at finishes materials and fixtures that you will consider using in your rehab projects. This will help you get a better idea of what tile, hardwood, carpet, plumbing fixtures and light fixtures costs for your rehabs.

#3 Contact Local Contractors for Pricing

Call local Subcontractors and get budget pricing for common repairs on your typical rehab project.

For example, call a roofer and ask what their average cost per Square of Architectural Asphalt Shingle Roofing would be on a 1,500 sf house, with a 6/12 pitch.

Note: Some contractors will be reluctant to share pricing without seeing the property, but tell them you are just looking for a rough budget number you can use on future projects.

#4 Compile Your Prices into a Spreadsheet or Estimating Software

Once you start to get a better understanding of Labor and Material costs you will want to store this data into a spreadsheet or software that you can use to help you streamline the estimating process.

The Book on Estimating Rehab Costs comes with a spreadsheet that you can use to help you populate your own database of labor pricing and material pricing. Or you can download my estimating templates I have in my Biggerpockets fileplace:

There are other Estimating Softwares available as well which can help you manage the Estimating process as well...

#5 Practice, Practice, Practice

Walkthrough potential rehab properties (or find properties virtually online) and practice creating detailed scopes of work, quantifying repairs and estimating rehab costs for the projects.

#6 Get Your First Rehab Project

You can practice all you want, but ultimately you will learn the most about estimating rehab costs by actually rehabbing a house. Getting your first rehab project will require you to create a SOW, talk to contractors, compare and review bid proposals, review budgets, & make countless trips to Home Depot. You will inevitably make mistakes and underestimate things, but you will learn 90% of what you know by just doing your first rehab!
