I acquired a condo which I am now renting. Therefore, I need to establish my basis for depreciation purposes (i.e., the value of "land" and the value of "improvements"). My cpa told me that in a condo you don't own the land so the value is zero. But when I found out that he was wrong on a number of other issues, I questioned this & starting asking around. Long story short the answers were: (1) zero land value; (2) you own a portion of common elements which includes land & buildings, so multiply the condo association's land & building value by the percentage I own (.71%) for "land value"; (3) just take the tax assessor's apportionment (50-50). I have read the IRS's materials and they do not address this issue. Since I plan to rent this property for a long time, I want to make sure I get this right (as I can only go back and amend 3 years for any deductions).
