Only if the tenant leaved. If leaving loses the rent-control, the tenant will stay. The price is well below market rate, then they wouldnt even get roomates, harming the entire rental market on both ends: by removing profits from the owner and decreasing supply. If rent-control didn't have the restriction, then it wouldnt make a dent into rent prices, but it would clearly show that it is a mere transfer from the owner to the rent-controllee.
