This isn't really true... it only applies to units that were built before a certain year (1979). If you are in any kind of modern unit / luxury unit as noted by GP, then this won't hold.
However, most landlords in non-managed buildings are fairly reasonable about only raising rent 2-5% a year. Your mileage may vary.
