People hate to hear it, but renting is transactional. People provide rental units as an investment, not for funnies.
There's no magic formula where one can pay less for rent than the monthly fee the landlord pays the bank, city and government for the place.
The alternative is people stop investing in rental units, we get fewer regular people renting out spaces and more large corporations who will do the bare legal minimum to keep the place livable while keeping the rent as high as possible.
The core of the issue is unsustainably high real estate costs, which not only balloons the cost of purchasing a property, but also balloons property taxes as they are based on the estimated value of the property, not the amount paid for it. This means landlords pay higher taxes for the same property year over year, even if the mortgage stays the same.
Ehhh don't test me
