I do not think he is a successful person, but I do believe he is a hardworking and enthusiastic person who has accomplished many more things than the average person of my age that I know here in NYC I would really like to help him.

I love that you are an enthusiastic house-hacker!

The Tenants friend pulled out a gun and shot the poor man multiple times killing him.

To be successful your wife must embrace the challenge and become enthusiastic about the prospect of being in business regardless of the risk.  

I recently had some trouble renting too and I started thinking, "maybe I should just drop the fee, especially if I'll eat it later anyway", or "maybe I should drop the rent", or "maybe I should reduce the security deposit", well I was showing a 1BR and a 2BR and had nothing after a month and all of a sudden, they both popped at once.If you know you're competitive, stick to your guns.  

And blast them away with a 12 gauge shot gun .  

No one is putting a gun to anyone's head and marking them buy homes at prices above their estimation of intrinsic value.

I carry a gun and don't like to go there at night.
