One more question on your spreadsheet ...
In your example, you used $5000 of Improvements to help figure a ratio at the time of purchase. I didn't do any improvements to the house before renting it out ... I only did improvements along the way.
The total of my improvements over the 6 years of ownership adds up to $33,260.
I don't think I can use that figure in the same way you did on your spreadsheet. The only ratio that I can come up with is the house/land ratio which is 72/28.
