What You Would Owe At The Sale
The recapture bill, in advance. Every deduction you take comes back when you
sell — the fast cost-segregation parts at ordinary rates (sec. 1245), the building
itself at up to 25% (unrecaptured sec. 1250), the rest as long-term gain — plus the
3.8% net investment income tax, plus your home state’s read of the same sale. This prints
that number the day you buy, not the week you sell.
