It is always a tough decison where to buy since good properties tend to be priced above what makes sense for cash flow (low rents compared to sales price). I personally like to buy in marginal neighborhoods since they tend to have better cash flow and my company is good at picking tenants like South Sacramento(95820, 95823, 95824, 95828). But some like more middle of the road neighborhoods and pay a little more, with less cash flow Natomas (95834, 95835) or Elk Grove (95624, 95757, 95758) make sense for that middle area. Higher end properties like Folsom (95630) can make sense if the deal is good and the investor can wait out the slow sales market. Of course, there are a lot more choices than that, but most fall in one of those three categories.
