Have a few properties here, the holton-wise neighborhood grading system helped incredibly. 

Blue collared neighborhoods with low crime.They cash flow the best :) 

I have a two family home in the Hillside neighborhood in Medford.

I have a relative who acted as her own project manager to fix up their personal residence in that same neighborhood.

Single family/townhome in NE or SE DC in a less desirable neighborhood.

Rents of properties that are updated range from $1,200-$1,450 (depends on BAH/Rank).

Ideal situation would be a 3/2 (or a 2/2 with a separate office since I work from home), small yard, decent neighborhood, washer and dryer in-house/unit in a neighborhood where you're hard-pressed to find bars on the windows and front door. 

So, anything that can cashflow $200-$300/mo. in decent neighborhoods.

In order to know if the property you are considering is a good deal, you will need to know the neighborhood, the comps, the amount of repairs needed and their costs, the amount you can rent it for, the financing you have available, etc.

I'm looking at a property here in Florida zip (33830), it's 3/1, 1157 sqft , in quiet neighborhood.
