It's not for everyone just like other trainers do not resonate with all people.

If you don't mind me asking, what is a a Sustainability Consultant?

"You too can be a real estate millionaire with no money down," Carlton Sheets said to me.Maybe it was the fact that I had no other prospects, maybe it was the fact that it was at 3 am, and everything sounds amazing at 3 o'clock in the morning ,(I'm not even allowed to have a credit card after midnight anymore) but his message really resonated with me.

I'd mitigate the worst case by not going over $150K on purchase price.Also, it looks like you have some money, so even in worse the worst case scenario, you could sell and sustain a loss without sinking.In the expected case you will invest about $200K and earn about $20K, a 10% ROI.  

I want to start investing there to increase cash reserves however I have an end goal of buying and holding multiple properties that are free and clear in order to sustain a comfortable, but not lavish, lifestyle for myself and my family. 

FHA is very picky when it comes to 3 and 4 unit MFHs making you prove the income from other units will sustain the mortgage which gets difficult since you'll be living in one of the other units and the LTV will be really high.

A new tenant just moved in and the other tenants have complained about the smell of pot resonating to their units.I have communicated to the new tenant about other tenants complaining about smoke resonating from her apartment and I pointed out that I advertised the apartment as a smoke free apartment.  

It seems to me you will be able to sustain the trials and will only come out stronger.

I have heard that your best chance of sustaining yourself full-time is exceeding 10 properties.

If your assumptions are based on how fast real estate values have been going up the last couple years, I would caution you that I do not think the current growth trajectory is sustainable.
