What rent-to-income ratio should I use?

A common benchmark is 30–35%, meaning rent should not exceed 30–35% of gross monthly income. Some landlords prefer a higher threshold in expensive cities (e.g. London) or when tenants have no other major debts. Consider reviewing the latest benchmarks from companies like Statista (https://www.statista.com/statistics/752217/household-rent-to-income-ratio-by-region-uk/).
