That's where I am; last year I brought in assistance to help with the owner statement data entry and managing getting the income/expenses into the system that we use for tracking.

Chances of those additions being well-done (and not negatively impacting the roofing, plumbing, or electrical systems) is slim to none.  

As for the wall you can do a lot of things like stagger studs in a double wall or use resilient hat channel system (horiz) over the studs. 

(I guess they maintenance the well system and provide salt, etc.) 

You may also see older heating and cooling systems, roofs that have a bit of wear and tear and parking lots that need repair.

I know I can go drive there, look up the school systems, check crime, and etc.. but I want to hear from *you* guys - How do you like investing there? 

Condition: Roof leaks in a couple of places, floor around the commode in the master bath is week and sinking, Central HVAC system does not work, mold infestation as a result of the recent SC flood, and the house is full of junk as the seller was a hoarder. 

How old is the roof, major system:, hvac, electrical, hot water heaters?

My point is use a software program to collect email address, just get there permission to opted them into the system.
