The Ultimate Guide to Rehabbing a Home in Houston

Fix and flipping a home means you need to know the do’s and don’ts of rehab work to accurately estimate costs before you make an offer.

If you estimate a fix and flip too low, you will lose out on profit. If you estimate too high, another real estate investor will swipe the deal from under you. Essentially, you need to walk the property like a pro.

Use these tips, do’s and don’ts and estimated costs for rehabbing a property in the Houston area.

Foundation Work on an Investment Property  

Hire a structural engineer for a foundation inspection and document what must be done.

An independent structural engineer can give you an unbiased evaluation, along with advising you where to put beams, how many, etc. He or she is getting paid for the evaluation and has no incentive on repairs, whereas a foundation company or contractor may have.

Look for cracks in the actual brick, which can indicate settling and foundation problems that could be costly. Also factor in any interior work related to foundation problems, such as replacing uneven flooring or doors.

Job Sequencing for a Fix and Flip

Once you close on a fix and flip home, job sequencing can be extremely important to your potential profitability.

Proper job sequencing can prevent increased costs. For example, if electrical work is done after paint, then you may need to cut a hole in the wall and redo drywall and paint. Use these steps as a guideline to job scheduling when flipping real estate.
