Dont we all...Put some of your own nut into the game then ask this question a few years later when you're established with a proven track record. 

That in itself is a game changer because it is a 50% increase you can charge.

Probably worth moving on, you could look into the NOD list if you can get that but even if you find the folks that own it this is a game of large numbers.

They have more skin in the game then you do.Make sure you get clear title.

REI is a numbers game. 

He needs to expect he will get these phone calls and he should know it's part of the game.

Management (even if you self manage you should budget for it so that that if something changes you have the room for it) repairs, maintenance, (this should b low initially since you just did rehab but in the rental game things happen and you should plan for it) Snow removal?

It puts them on notice that this isn't a game.

I just want to make sure I am following a sound strategy that puts ahead of the game now instead of behind. 

I am not suggesting that you get a printing press or copy machine and literally print paper money.
