Families now have way less disposable income, I could go on, on this.

Hi Matt, whenever evaluating an MTR market I would suggest looking at Furnished Finder, Airbnb/VRBO (30+ day stays), and Zillow to try and see what other online listings are available. 

They'll need information on the deal (revenues, expenses, income, etc..), but they should be able to give you an idea of general terms (interest rate, amortization, fixed period, etc..) with some basic information.

DO you have access to an online Owner Portal?

I am looking to add passive income while still working my current job until it makes sense to do real estate investing full time. 

Buying a property with existing tenants can definitely have its perks, especially if you're looking to hit the ground running with rental income.

If not, they’re fine keeping it, especially if it’s still generating income.

The rental income just sits there in a non-interest bearing account until I invest in something.

So if you made $100 (on line 1) but used $100 in advertising (line 8) your taxable income (line 31) would be $0.

However, financial freedom isn't just about replacing your current income.
