If the investor is ok with 0% or negative cash flow and only looking to build equity over time by paying down the mortgage then by all means move forward.

I'm sure there's a wide range of talent represented in their employees, and I can't speak about every person who works for either of these companies.

I look forward to speaking with you soon. 

If you have already contributed to a tax advantaged account, generally speaking, your "job" is to get that money to make the most money.  

Now it is in both your names so to speak.

If this is a "house hack", then your monthly negative cash flow looks to be about the same as rent anyway.

The only subjective area is just how much you can maximize the travel benefits (assigning a dollar value to your points) and how quickly they will be devalued by the travel companies (it is inevitable like inflation, but how much and how soon is unknown)Very generally speaking, the best cash back cards provide better rewards than travel cards, however signing bonuses tip the scales in favor of travel cards for the first few years.

@Dave Levy, the speakers don't start til 7PM or later, but since there are 5 of them, they will likely be still speaking after 8:30, so you are welcome whenever you get there. 

What specific things should I look for, both positive and negative?
