Tagteam pointed out a rather important aspect that you must be clear on.
When you sell the property, all depreciation must be recaptured in the year of the sale. That recaptured depreciation is taxable no matter what, with no exceptions. It is not included in the "2 of last 5" rule. Take note that the recaptured depreciation does get added to and included in your overall AGI. Therefore, it is perfectly possible the increased AGI could bump you into the next higher tax bracket.
