EDIT: of course if you mess up, that mistake is now set in stone and backed by legal resource of your city, so it’s not risk free.
this assumes the returns set out by the rent control is appropriate in all future situations. Even with the allowance for increases, there are still situations where such an increase is insufficient.
Unfortunately, the proverbial cat is out of the bag and we will likely see repeats of such “subsidies”. It’s unclear how it will change the calculations long-term. Short-term, it has already driven the unlucky small landlords out of business and forced surviving to keep greater reserves. This increased reserves need will definitely hamper future development and probably will drive rents up even more due to lack of supply. Large corporate landlords tend to focus on the higher end of the market, but the shortage is in the more affordable price range…
