Frequently asked questions

What percentage of income should rent be?
The general rule is that rent should not exceed 30% of net income per month. If rent exceeds 40%, it is considered a heavy burden and should be considered to find cheaper accommodation or increase income.
Where's the 30% rule for rent coming from?
The 30% rule originated from the U. S. government housing program in the 1960s-70s period that stipulated that residents should not pay more than 25-30% of their income for housing.
What if the rent is higher than 30%?
Consider finding a cheaper room or apartment in the same area, or a location farther away but close to the tram, sharing a room with friends, or targeting income to reduce the rent proportion.
