But remember to only concentrate on one thing at a time.

My properties are concentrated around Gravios park, but I'm looking to expand into better class neighborhoods. 

I suggest a good dose of C combined with B (cause that's inevitable).Just concentrate on #9 and #10 - real estate investing is a long game (at least IMHO).

I have been concentrating on buy-and-hold rental properties in more rural areas of North Florida and, to a lesser extent, the Ft Lauderdale area and I've seen the same thing:  Prices have risen more quickly than rents to an extent that it is difficult to find properties with the right fundamentals.  

I do almost all of my maintenance and what I don't do I have long-term business partners handle according to my specifications -- lasting fixes when necessary, high-quality paint that can be touched up repeatedly, Whirlpool appliances, hardwood and tile I do myself.I am on the electrical board and the outlets, I am on the roof, I am inspecting the windows, I am on the gutters all the time, I am liberal with the weedkiller concentrate, saving myself money in the long run wherever I can.What happens when you're extended from here to eternity with 75 SFR and three furnaces die in the first heavy cold snap?

Probably because it attracts the poorest people in high concentrations.

We have the greatest concentration of commercial grows in the state.  

Work hard, take on additional work, live a conservative life style, change your habits and circle of friends, save money and concentrate on getting your credit up into the high 700s.To be successful you need to modify your life style.

Your coop is a liability that I would off load and concentrate on investing as your #1 priority.Your plans to have children is going to be a major constraint on your plans going forward.
