Investors & landlords

Ugh... that makes sense and I wonder if I split out our personal side correctly this year for taxes.  I started depreciating the FMV of renovations applicable to our personal side, date-of-service starting from the date we rented it.

For example, I determined the FMV of the driveway resurfacing (discounting for wear-and-tear) and started depreciating 50% of that value. 50% of it was already being depreciated for the rented side. And, or course, I've already submitted our taxes so can't go back and easily change that.  Can I continue to depreciate our personal side renovations (now rented) in this way, or did I mess things up?
