Yeah, this is all well-established. When you buy an apartment building you know the legal rent for every apartment. That only changes by a percentage amount every year, and the amounts are available historically, and landlord reps make up a big chunk of the board that sets those percentages.
There’s no mystery here, everyone knows the score, it’s just that landlords try to take advantage.
Doesn’t everyone try to take advantage? I’ve never heard of renters offering to pay more than rent, it’d be like haggling with a street vendor to pay a higher price.
Sure, but there used to be big loopholes, so, for example, if you made capital improvements to an apartment you could increase the rent further. Landlord buys a $500 fridge and hires his buddy to install it and gets from him a receipt for 8k in installation fees. Now he can raise the rent $800/mo. the same sort of shenanigans aren’t available the opposite direction for the tenants.
