Frequently Asked Questions
The 30% rule is a widely accepted financial guideline suggesting that you should spend no more than 30% of your gross (pre-tax) monthly income on rent. This ensures you have enough money left over to cover necessities, pay off debts, and save for the future.
Common in highly competitive real estate markets like New York City, the 40x rule requires a tenant's annual gross income to be at least 40 times the monthly rent. Mathematically, the 40x rule and the 30% rule yield the exact same affordability limits.
Landlords evaluate your application based on your gross (pre-tax) income. However, for your own personal budgeting and financial safety, it is often wiser to calculate your 30% limit based on your net (take-home) pay.
Your base rent is rarely your only housing expense. You must also budget for utilities (electricity, water, gas), internet, parking fees, pet rent, and required renter's insurance. These hidden costs can easily add $200 to $400 to your monthly obligations.
