Pass a law making rent based on the renter's income. Exclude only combined income of $250,000/year and up. Set aside 20% of properties at market, no more. Only minor once every five years cost increases may be permitted.
Why is this important?
Rents across the country are skyrocketing. People cannot afford to pay a market rate for a necessity. If the market cannot stabilize rent as affordable then it must be mandated by law. It literally makes zero sense for a renter's rent to go up every year just because vacant property is in demand, so this fixes that. People on fixed incomes are particularly vulnerable to this treason.
