I have been looking for the best information, tools and skills to make my house flipping business run better. After losing tens of thousands of dollars to bad contractors, I sat down with my bank and created my own construction estimating tool. The excel document you are about to invest in has been time tested and I use it on every house I buy, fix-up and sell. We don’t have to remember everything, because it covers everything, because I don’t trust my memory. You won’t have to be held hostage by a contractor again, because this estimator asks all the questions you need to cover with your contractor, including plumbing, framing, electrical, framing, painting, flooring, sheetrock, roofing siding, etc. One of Napoleon Hill’s top 10 rules of success is making sure we cover all the details. This is an excel spreadsheet that you can use to track your repairs.
