She is 100% right, there is definitely a good market in the perimeter cities around Nashville and I think as a new investor living in the Nashville area you will want something you can regularly manage and not in another state. 

@Alexis Schreier I'm using Perimeter Property Services (PPS).

Now, if we're talking inside the perimeter, no one really has a clue when the rougher areas will get better (if ever).

Around here the perimeter of the floor slab needs to be insulated.

I have had no complaints from any of the tenants after doing this and I simply periodically apply this along the border and between the deck boards of the home; downside is you can see it around the perimeter and a heavy rain will wash it away. 

Have them supply push mower and just mow perimeter of back yard.Your thoughts?  

I see what some SFR are selling for inside Atlanta perimeter and I just shake my head.

outlining timeframe and other perimeters of its status.

I doubt you'll find much inside the perimeter that's just a cosmetic rehab. 

@Dave Dunaway as long as the units meet code, you're good...we just passed on 8 duplexes where the design called for basement apartments...typically, below grade footage carries less value than above grade...so, for example...if the upstairs is $100/sq.ft. you won't double your square footage at the same rate by putting living space in the basement....and you are basically asking the auditor to reassess your taxes based on the square footage...so you claim it...you pay taxes on it.Most of the other inherent issues are around controlling water...the right thing to do would be to install a perimeter drain and sump...if there is any moisture or water intrusion in the basement (and there will be), you run the risk of mold inside the finished walls...I think my ultimate questions is who would really want to rent an apartment with the bedroom in the basement...even if it is finished, but who knows.
