The Real Estate one is definitely one on my list I actually just finished reading the Business of the 21st Century!

24 units is definitely a decent size and you spread your risk and keep a big % of your income when a tenant or two move out. 

While you could definitely handle the communication and management from home; you DON'T want to be driving to clean. 

There are pockets of 35805 that you can definitely find good properties and positive cash flow. 

I think they can work, and I have different partners on a number of deals, but you should definitely know who you're dealing with and be super explicit about who's responsible for what, especially what happens if things don't work out as planned.For example, what if a tenant really trashes a unit/property and it takes several months to re-do and re-rent, making you cash flow negative for the year.

I will definitely notate on my notes when making deals!

Although, I'm sure that there is a definitive answer to that in your state. 

It’s definitely a lot of money to be leaving on the table if I don’t do a significant rent increase.

I'll definitely make the short trip out there here in a few weeks.

I will definitely start looking at my options and will reach out when it comes time for us to make our move.
