Intuit Payment Network is a natural progression.

But intuition goes a long way and I somehow just feel good about CC.

Interestingly, my intuition has been telling me go multifamily as well, so your advice seems to be confirming my gut feeling.  

It seems intuitive and easier then trying to find a property halfway across the country. 

We only use AirBnB as their cut is low, the management tools are intuitive and we haven't felt like managing multiple calendars with other services.

@Joshua Biondi I think my advice will be a little counter-intuitive but lay out for the realtor if there's anything that you don't know about navigating a real estate purchase. 

Rick H. mentioned, reliance on calculators hinders your ability to think instinctively , objectively, you won't be able to adapt variables in reality that come to play in the analysis of real estate, or law, or economics, or finance or accounting or any other professional endeavor that requires intuition, abstract thinking or layers of relevance of variables in circumstances or situations. 

By all means, give back, use your intuition about a tenant, and the first time the property is wrecked and you have a $3-5k bill to put the house back together again, you'll realize that giving back is not a good way to go.Been there, done that.It all comes back to screening.

Your intuition tells you a lot. 

I balance that with mortgage/insurance costs and throw in some speculation on property values increasing/decreasing and add a pinch of intuition.
