Rent control makes apartment rentals more expensive (and lower quality).

Regarding housing prices: this may be true in first-rate cities like San Francisco or New York, but here in St. Louis (and in dozens of similar cities in the U.S.) housing is usually cheaper in the city's core. People left for the suburbs to get more space, because they had automobiles, because the housing stock in the suburbs is much newer, because blacks were moving in, and because of crime levels (some real, some perceived).
Also, rent controls depress the quality of housing stock.
