One of the most common questions buyers ask is, “How much can I borrow for a mortgage?”
Let’s break down the 2025 affordability rules and what lenders are looking for.
- How Lenders Calculate Affordability
- Income multiples: Most lenders offer 4x to 5x your annual income.
- Debt-to-income ratio and regular expenses.
- Credit score and employment history.
- Deposit Size and Loan-to-Value (LTV)
- A bigger deposit = better interest rates.
