Whether or not you want to live off the cash flow, why risk your money for a property that doesn't cash flow?

Risk free for me, huge risk for you. 

If not, you'll need to carry the difference.  

There were several times where we felt like we were going to lose money on this property, but we carried on and were able to finish the house.

The math for me is if one is not a complete loss every 2 years, I make out better.7) That said, I carry liability insurance on each

I'm seeing a lot of videos where investors are growing from 1 rental to 100 rentals overtime, but still can't figure out how these investors are mitigating the risk while growing so rapidly?

You may also be thinking of using the money that actually belongs to someone else and buy even more properties with the money while you put yourself in a position to be carrying more than one mortgage yourself.

If you immediately raise it to an amount she really can't afford you run the risk that she stops paying because she can't afford it and then you're stuck with a non-paying tenant and a potentially a costly eviction, which wouldn't be good for either of you. 

More units (usually) less risk (financially).

I am new into investing and was wondering if I should take the risk and invest into it granted I do not know much about foundations of a home.
