I have limited cash in hand that I'm able to invest...I'm not sure that the current equity in my house is enough either to use it for future investments. 

It's a nice benefit while you live there, but it shouldn't be the deciding factor in what you do next...it can play a part in the discussion, but the much greater benefit is your ability to sell tax free on your personal residence with a 121 exclusion. 

I found myself a guy who was willing to teach me the whole thing for free and doing it at one step at a time. someone like him is just after your money.

Otherwise it couldn’t be free and clear and you would not be able to purchase it.  

@Mojgan Azar Second the opinion of Option A where you get to stay hands on with your investment.

Especially because in 10 years, if you need cash, you could consider a cash out refi, the tenants pay the mortgage, and you just got money tax free. 

I'm reminded from non-RE friends about how I take risks with real estate and I should be try to be mortgage free but when I look at my stocks, I have no control over the value other than to buy or sell. 

One the one hand, I like to be with my team leader.

Mine is at 2, but honestly could go on forever.If anyone is reading this and wants help, feel free to reach out.

So, effectively getting some of the profit tax free.
