I originally purchased a 50% share of a property in 2009 (aggregate purchase of price of $175k for the property) and subsequently purchased my partner's 50% share (at a cost of $121k for her portion only) in 2016. I then paid off the mortgage in 2017 and began renting out the property in March of 2018. How do I calculate the Original Purchase Price, Available Date and Purchase Date in order to determine the depreciation (i.e. what amounts and dates should I use for each field)?
