Does a home office deduction wreck the exclusion on a live-in flip
Take a live-in flipper running a service business out of a bedroom for five years, roughly 12 percent of the square footage, with an accountant taking depreciation on that portion, call it $3,400 a year. Work through the numbers. Bought at 310, roughly 85 put into it over four years, comps saying 505 to 520. Gain lands somewhere near 100 to 115 after selling costs, well inside the exclusion on paper. Where this gets murky is the depreciation. Depreciation claimed on the office portion doesn't get excluded and comes back as its own item at sale, which on four years is maybe 13 or 14k. Some sources also hold that using part of the house for business inside the same dwelling doesn't split the property for exclusion purposes the way a separate structure would. Both of those can't be the shape of the same rule, and this is exactly the kind of conflict worth bringing to a CPA directly rather than accepting a first answer. The right approach is to ask specifically how the office square footage is treated at sale versus how it was treated for the annual deduction, and to get that answer in writing before listing.
