The amount of people in this thread who think that rental properties are based on anything other then what the market will bear is hilarious.

Your rent is always at the maximum the landlord can charge. There may be isolated landlords who are too lazy or even kind to raise rates, but 99% are charging the max they can while still keeping the unit occupied.

Pouring grease down a drain and causing plumbing problems doesn't have an impact on the broader rental market and amount that any indivudal landlord can charge while maintaining occupancy.

If the landlord tries to raise rent by a meaningful amount in order to recoup maintenance costs, they will either not rent the property because its priced to high or they would have always been able to rent the property at that price and its not magically justified because of oil down the drain.

No no, you don’t understand. Landlord bad. If landlord pay for fix pipes then rent go up $2000.

People are too dumb to understand economics. I can’t tell you how many overpriced apartments sit unoccupied for months on end in my area because their competition has better prices.
