Frequently asked questions

What is a good debt-to-income ratio?
Aim for a back-end DTI of 36% or lower and a front-end (housing) ratio of 28% or lower. Lenders may approve higher, but staying under these gives the most breathing room.
What is the difference between front-end and back-end DTI?
Front-end DTI counts only housing costs against gross income. Back-end DTI adds all other monthly debts like car loans, credit cards and student loans.
Does rent count in DTI?
Yes. Even though rent is not a loan, lenders count it as a recurring monthly obligation when working out your debt-to-income ratio.
Should I use gross or net income?
Use gross monthly income, your pay before taxes and deductions. Lenders always calculate DTI against gross income, not take-home pay.
Is this financial advice?
No. These are estimates to help you plan and compare options. Your real figures depend on your lender, taxes and personal situation, so check with a qualified professional before deciding.
