@jellis7  you are definitely treating flipping correctly, that you have no deductible expenses related to the houses being flipped, although you might have ordinary expenses such as tools, business liability insurance, office costs that do not have to be charged to each property. Projects as highlighted by @IntuitLily should do the trick, although class tracking (if you are on Plus) would also be a route to follow (but limited to a maximum of 40 classes)
