If you're talking about the physical temperature, I don't blame you.

It seems like a way to get familiar with the world of real estate investing that's not too expensive and much easier to deal with than physical properties.

It all starts upstairs (Higher Power, and your mental alignment), then the physical manifestation.Keep kicking butt!

Avoided having to show up at the unit multiple times and even weeded out those who were flaky since i didn't need to be physically present.

It also gives you flexibility to "not renew" less desirable tenants or push rent increases.Even after taking ownership, I would advise not just sending a letter, but also physically going to the property to meet them.

After keeping out cap ex, vacancy, etc I cash flow $450 with no mortgage. 15% return CoC vs 8%, instant liquidity (on the cash flow), plus I own a physical asset and get the tax deductions vs paying taxes on dividends. 

You will have more than a fair share of crappy yards and homes that have physical distress.

At that age, your physical health will deteriorate, and you will need medical care.

I think a lot of the "time and financial" arguments are really just a dog-whistle for the belief that the work is hard, dirty, physical, menial, and beneath their station in life.

That will improve your health (mentally and physically) and enable you to sell the car which would give you more money to pay towards your debt while saving thousands a year on insurance and gas.
