| Lets assume that there were 2 rental properties and both partners owned 50/50 prior to 2007, and in 2007 effective 1/1/07 they did a like kind exchange and both partners now owned 100% of 1 property. I think that this the actual scenario you are presenting!
Now that the partner has acquired 100% of the rental property, there is an additional amount of basis that is acquired and depending on the that amount, the property would be subject to additional depreciation in 2007. This amount would now equal to sum of the depreciation on the original 50% amount (that was claimed in 2006) plus the depreciation on the newly acquired basis (on the exchange of the 50% interest on the 2nd rental property, assuming on exchange of any cash). |
