Frequently asked questions
Is the 30% rule realistic?
In expensive cities many renters spend more. Spending over 30% is officially called 'cost-burdened' in the US; over 50% is severely cost-burdened.
What is the 40× rule?
A landlord screening test: your yearly income should be at least 40 times the monthly rent. For $2,000 rent that's $80,000 a year.
Should utilities be included?
Yes, if they aren't included in the rent — add them to your rent when comparing with these limits.
