Hello Derrick,
I would highly suggest getting a professional accountant to help you with this. His advise will help you arrange and be ready for taxes when due and what you need to claim.
Have a great day.
keep good records of all items ie leases, utility bills, roof repair bill, fridge bill, mortgage statements etc
have evidence of value of the rental property at time of conversion as you will have to pay capital gains taxes when you sell it eventually on the gain from that point forward (this could be an appraisal, or a realtor opinion, or just comparables)
