In my observations, a lot of well off people in the area seem to use these investments for tax reductions and not cash flow investments, making the cash flow properties even harder to find as prices are inflated by that demand and they could care less about positive cash flow.If you can boost rents to 1% or more of the purchase price as @Rich O'Neill suggests, you'll find its probably much closer to a worthwhile investment.
