Frequently Asked Questions
What is mortgage affordability?
Mortgage affordability is the amount you can comfortably borrow to buy a home, based on your income, expenses, and financial obligations. It ensures you can manage monthly payments without financial strain.
Why is the debt-to-income (DTI) ratio important?
The DTI ratio helps lenders determine how much of your income is used for debts. A lower DTI ratio increases mortgage affordability, making you a less risky borrower.
How do interest rates impact mortgage affordability?
Interest rates affect the cost of borrowing. Lower rates reduce monthly payments, increasing affordability, while higher rates have the opposite effect.
What role does my credit score play in mortgage affordability?
Your credit score influences the interest rate you’re offered. A higher score usually results in lower rates, improving your affordability by reducing monthly payments.
What is the recommended percentage of income to spend on a mortgage?
Financial experts recommend spending no more than 28% of your gross monthly income on housing expenses, including mortgage payments, taxes, and insurance.
Can I improve my mortgage affordability?
Yes, you can improve affordability by increasing your income, reducing debts, improving your credit score, or making a larger down payment to reduce the loan amount.
