I feel pretty set on what I want to do but some people have told me I need to be careful on what I choose and to make sure to have a fall back plan in case the market crashes or being realtor does not work out.

My usual response to a multiple offer situation is: "Let me know if the other offers don't work out." :)But good luck!

While location plays a huge role in determining if numbers work out for any deal, I like to keep an open mind.

If this is a good tenant all of this stuff will work out.

I feel good about the deal and What matters is how the numbers work out.

Could you work out a deal with the bank and get a statement in writing that they would not call the loan due if the title transferred?

In the areas we are looking , the BRRRR deals wouldnt work out in such a way that at refi time we'd be getting 100% of our funds back with a 75% LTV loan.  

But what I really want is the freedom to be able to take risk like start my own business, get into a startup, etc. but have a basic safety net or backstop in place in case things don't work out.  

You might be able to work out a referral deal with another realtor, it might even net more than wholesaling if you find the right agent.

A mobile home might work out but watch the space rent as that can be a killer and they may be harder to fill a vacancy.
