for real property, depreciation is computed using the mid-month convention.
so if you purchased it in April (based on what you supplied as fair rental days) you would only get 1/2 month depreciation for April and then a full month for the rest of the year 8.5 in all.
i agree a full year s/b $5648 (based on the tax basis of 1/2 the building being $155,337) and thus depreciation should be 8.5/12 of a full year or $4001. rental days do not enter into the computation of depreciation. if you changed FRD to 10 I'd bet depreciation wouldn't change from what you have. I assume you use 0 for personal use days. $2433 make no sense to me. it almost seems like TT took 1/2 the total cost and then subtracted the full cost of the land to come up with the depreciable basis of the building.
my guess is that somewhere in answering TT questions something was entered incorrectly. we can't see your return
.
