And I've found that when you tell people that there will be no appreciation, they think that you are wrong, too conservative, or trying to CYA.I think that the high cash flow low or no appreciation model does have some merit, but I wouldn't have that as my only investment strategy.We've talked about buying in neighborhoods with good schools and low crime and growth, but another factor is the percentage of rentals in the neighborhood.
