In my case, there'd be agency that specializes in cost segregation (with fees and not cheap) and they will give me 3115 to file. It will have new 5/15/27.5 years cost bases. The 5/15 years would be on Other expenses section on Sch E, but how'd we tell TT that the new base for 27.5 part is not the old purchase price - land cost anymore, perhaps by reducing the (purchase) cost by the same amount of 5/15 years from 3115? I saw this link https://ttlc.intuit.com/community/investments-and-rental-properties/discussion/bonus-special-depreci... for similar matters. The host says he "restarted by first adding the "27.5 year structure" (total cost minus the cost of segregated 5 and 15 year items)". I am wondering how he did that as TT 27.5 year asset will always ask you total cost and land cost. I am guessing he might have used purchase/total cost minus 5/15 years bases from the cost study and just entered that on TT directly? Is that the correct way?
