My first questions exactly. Renting out but giving a more discounted rate the poorer the tenant is probably the only sustainable approach to keep them having a home as living costs just keep rising. Of course, the discount should gradually dissolve as the tenants get better paid jobs to avoid someone moving in poor and keeping the same flat after ten years of career development. Getting raises or better paying jobs would pay off but rent would just eat a bigger portion of the monthly costs until they would be on par with market rates.
