Frequently Asked Questions
How much house can I afford?+
Lenders typically use the 28/36 rule: housing costs should be under 28% of gross income, and total debts under 36%. On $85K income, that's ~$1,983/month for housing, supporting a home around $300-350K depending on rate and down payment.
What is DTI ratio?+
Debt-to-Income ratio compares monthly debt payments to gross income. Front-end DTI is just housing costs. Back-end includes all debts (car, student loans, credit cards). Most lenders want back-end DTI under 36-43%.
Does a bigger down payment help?+
Yes. A larger down payment means a smaller loan, lower monthly payments, and often a better interest rate. At 20%, you also avoid PMI. But even 3-5% down can work with FHA or conventional loans.
