James, if you get the rent bumps you are projecting, the renovation ROI seems very good, even at a middle $10k/door upgrade. 

These cheap out of town properties seem like a good deal but the leverage you can get on owner occupied properties makes it unbeatable for building wealth.

I've noticed that charging by pages doesn't seem to work because after filling I have to go through days of communication with the municipalities to get results.

Seems that they will conflict at times. 

If it seems like too much, think about traditional rentals, rent-to-own, or teaming up with corporate housing companies for a simpler and potentially more guaranteed approach.

Maybe, but maybe not (see below).Another assumption I'd suggest re-evaluating: you seem concerned that if you have a 30 yr mortgage and you just let the tenant pay it off at the minimal rate, you'll have the mortgage until you're in your 50s.

Seems most decent duples/tri's and quads are quite hot!

Seems built to appeal to younger folks.The loans aren't available in all states.

It seems as though most people in this world are so focused on themselves that they forget to care about others.

2: Does purchasing a house 100% cash seem like a good strategy for my available cash or is there something else I should be thinking about?
