# How To Calculate Rehab Costs

Have you taken the time to accurately determine your real cost to acquire, rehab, and sell a project home? It’s incredibly important to do this so that you can determine the Maximum Allowable Offer (MAO) for an investment project.

Your MAO is based on a formula you use to determine the profit you will make. Rehabbing is a relatively risky business requiring a large amount of capital. That means the risk/reward ratio should be high. The typical profit margin is between 35% to 30% or a purchase price that is 65% to 70% of the After Repair Value (ARV).

The MAO is calculated by taking the ARV (the price you will sell at) and subtracting out the expenses you will have during the rehab. The formula is:

Retail selling price – purchase price – rehab costs – carrying costs – holding costs – closing costs = Profit X 0.65 = MAO.

All of these numbers will vary not only by region of the country you’re investing in but by exact neighborhood you are investing in. An experienced investor should have no trouble quickly determining the retail selling price. Carrying costs include your cost of capital (any loans you have to pay interest on). Rehab costs are the most challenging to calculate and I’ll go into detail shortly. Holding costs include insurance, property taxes, and utilities. Closing costs include points paid for loans, realtor commissions, and a slew of other smaller fees.

## Cost of Rehab

Rehab costs vary both by region and materials used. You need to become proficient at estimating your own rehab costs. Don’t use the numbers I’m going to give you. This is a technique for estimating rehab costs but you need to use numbers based on your location and materials.

• \$215 per window when replacing single pane windows.
• \$200 for every 100 square feet of replaced roof. The cost is more if old roofs need to be ripped off.
• \$200 per 100 square feet of siding.
• \$2.25 for a linear foot of gutter.
• \$6.65 per square foot of ceramic tile.
• \$325 per dumpster for demolished materials.
• \$450 per exterior door (includes new locks and storm door).
• \$2.00 per square foot of refinished hardwood floor or \$5.25 per new square foot.
• \$3,000 for 3 new kitchen cabinets.
• \$40 per square foot of granite kitchen counter (includes backsplash).
• \$2,600 for stainless steel stove, microwave, and fridge.

Those include the basics for a typical remodel. However, don’t forget to include other items such as garage doors, rebuilding porches, new asphalt on driveways, landscaping, new bathroom fixtures, drywall, and painting. In the end, add 10% to your estimate to be sure of coming in on budget.

You will be making this calculation frequently. Rehab investors typically have 20 offers rejected for every 1 accepted. You want to be both quick at estimating rehab costs and thorough. The best way of doing this is having a very detailed electronic spreadsheet. Include every conceivable cost to use it as a checklist. You want to automate the spreadsheet to capture all of the information needed to calculate your MAO. With experience, it should take you less than a half hour to fill out the spreadsheet for a possible deal. When the MAO pops out of the spreadsheet, you know exactly at what point to hold the deal or fold on the deal.
