How does change in ownership percentage affect depreciation?

Scenario: Rental property purchased for $100,000. I put in $60,000 and am 60% owner and my business partner put in $40,000 and is 40% owner. We have been entering depreciation for the past 3 years using Schedule E based on our ownership percentages. This year there were significant repairs totaling $10,000 and so my partner offered to pay for them in exchange for 10% more ownership.

 

My understanding  is my partner can claim 100% of the extra $10k in expenses and I need to change the depreciation schedule to reflect this change. I can't just change the amounts for the asset in TurboTax because it will mess up what is reported for the depreciation already taken in prior years. Based on reading this other question it appears I need to create a new asset and deduct all prior depreciation I've taken from the COST and add it to the LAND.  That article refers to an increase in ownership percentage, so I'm wondering if it is the same process for a decrease? Also, with my decrease in ownership do I need to start a new 27.5 year schedule based on the day ownership percentage changed or can I get TurboTax to continue the schedule that started on the original date of purchase?
