Frequently Asked Questions
The 30% rule suggests that you should spend no more than 30% of your gross monthly income on rent. This is a common guideline used by landlords and financial advisors to ensure housing costs remain manageable.
A down payment is a one-time upfront payment that can be spread over the lease term to increase your monthly budget. By dividing the down payment by the number of months in the lease, you effectively increase the rent you can afford each month.
If after subtracting expenses, debt, and savings from 50% of your income the result is negative, it indicates that your current financial obligations exceed the recommended housing budget. You may need to reduce expenses or increase income to afford rent.
