The credit report and background check does not indicate any red flags. 

In addition to watching the market (day & night:) I have a degree in economics: all major economic indicators point to increase; not to mention many relocations (including businesses from CA, & North East.

Also when I negotiate my leases, I negotiate getting oil changes and servicing included into my lease so that I have pretty minimal upkeep costs. 

There is a box on the form that indicated it is from rent which at least in my case is always Passive Income NOT SE income that I would have to pay SE tax on.

Great Ontario specific advice on systems and processes to minimize your efforts. 

@Ryan BuchananThey will likely issue you a 1099 at the end of the year indicating to you how much rent they paid you for the year.This will not change anything for you as you normally have a requirement to report all income(whether given to you on a tax document or not).

Do your best to minimize disruptions (eg group showings).

If you pass all of the qualifying tests and indicate at tax time that you’re a real estate professional, does that allow you to use all of your losses to offset gains?

Note that it's minimal service, they list and you do the rest.

This will allow you to minimally encumber the paid for properties and should allow you to consider good cash flowing investments.
