> In less than 3 years the rent in our working class city went up 45%.
I sympathize with that but I want to make sure people understand the dynamics. Prices are driven by supply and demand. If there's only one empty apartment in the city and you're willing to pay $2000/month, I am gonna have to pay $2100 month if I want to live there instead of you. That's sort of separate (though related to) prices of houses.
What will make rents go down? Only two things: demand goes down, meaning people aren't looking to move into / are moving out of the city. This happened in NYC rents in early covid as everyone bailed out. So one way to drive prices in your city down is to have some even that renders it undesirable (COVID, defund the police, rising crime, suburbs more attractive with work from home, etc.) The other way is to increase supply - that is to build more housing. Counterintuitively, this happens more when prices are high because it compels builders to create more housing stock.
People in NYC love to complain about all the new construction going on (or at least that was going on in the last few decades) but imagine what rents would have been without that.
