Things doesn’t usually work like that.
Rent subsidiaries work by your annual income and usually the cost of your rent.
For instance they may pay you 300€ a month for your rent as long as your income is less than 30.000€ a year and your rent is bellow 800€/month. And increasing the thresholds if you have kids or if you are part of a protected collective.
They may be above this thresholds. It’s pretty common in Europe for people who struggle to meet ends are above the needed thresholds for getting help.
