The best tips for optimizing your housing costs
The adequacy standard states that at least 95% of households entitled to a rent allowance are allocated suitable accommodation. This means housing where the rent is below the ceiling threshold. So about 600 euros of rent per month.
This allows for a good match between income, household size and rent level. This allows entry-level tenants with limited income to cover housing costs.
Income and family composition change over time. Entry-level earners may acquire a (much) higher income within a few years. Income may decrease when a tenant retires. Family composition may also change. Through cohabitation, expansion of the family or death.
That is why it is a good idea to periodically check whether the income still corresponds to the rent paid for the unit and whether the unit still corresponds to the composition of the household.
