In Canada we have a 25 year mortgage (for example), but we renew it every 1-5 years (they started a 10 year one as well) at the current interest rate. 

Are you working with a current lender?

I'm currently looking in the Lakeland area right now also Ocala and Gainesville for cash flowing properties.

This implies if you sold and bought the exact same house your current property tax would increase substantially.  

These properties also offer you the opportunity to perform cost segregations which help with those current taxes. 

Do you currently have equity in any of those homes?

Rental Property is located in Upstate NY in Oneida County.I have a tenant who is currently scheduled to have their lease end at the end of February; they will have only occupied the unit for a year at the end of their lease.I'm not looking to extend their lease and would like to have the unit vacant upon lease end.

You have to adjust your expectations to match current reality, which includes higher mortgage rates, higher prices, more expensive taxes and insurance, more competition, etc.

There, now it will appraise as a FORMERLY illegal bathroom, current storage closet (appraisals are about the CURRENT property, not speculation about what the property might once have been historically). 

@Patrick Pan, if I was operating in a state where that was a concern I would just contact their current landlord for a reference.
