Rental Portfolio Question

[Chris Jones]

I recently closed on my second single family home in Winston Salem, NC.  My strategy is to buy and hold single family homes in areas that produce good rental income and have significant potential for appreciation.  I currently saving for my third house, but I am unsure  if I should buy a third property in Winston Salem or branch out to surrounding towns like Charlotte, High Point, or Greensboro.  Maybe I have too much exposure to a small market?  Any advice is appreciated!
