I'm going to reiterate what's already been mentioned above, but I'm going to actually give you examples of why it's relevant to you to find a U.S. tax professional.1 - You're going to need to file U.S. taxes once you have property down here, there's federal filings, state filings, and sometimes local filings too2 - Tons of tax treaties between the U.S. and Canada that are easy to miss and can cost you a lot of money (important one with rentals - effectively connected income - if the professional you talk to doesn't know what this is, run away)3 - The amount of days you spend in the U.S. needs to be tracked and if you go over a threshold, all of your worldwide income could be taxable by the U.S.4 - Selling real property means up to 15% of your sales proceeds might not be available to you for years (FIRPTA)5 - Lots of nuance at the state and local levels, which both want to take as much money from you as possibleMain takeaway here is that you should find a U.S. based tax person.

They mentioned they didn’t need any income.

St Cloud MN Duplex, list/purchase price $259,900market rents $1,610 per unit BUT yes, if one really wanted to sec8 income standards are $1,957 per unit so one could go that direction if wanted be.

FHA now allows us to count rental income from an ADU (additional dwelling unit) to help borrowers qualify.

If you don't care about income and are more of a capital gain kind of guy, prices are already high (as you noticed) and there's plenty of land available to buy so I'm not sure how much is left in the tank.

They generally treat the debt like they would with a rental and count around 75% of the gross mortgage payment as "income" in the DTI calculation.

Both are for tracking income/expense and generate reports (P&L, cash flow, but not balance sheet) only, not for listing, screening, collecting rent. 

My bank account is connected to Stessa to eliminate the need for me to manually track income, expenses etc. 

I don't know your living situation but if your paying x,xxx for rent or a mortgage and instead by living in one side and renting out the other you will be paying y,yyy instead and y is less then x that's great, especially if you can rent out your primary residence and make income there too. 

The income of a property manager is dependent on whether you property is filled with tenants as well.
