Your maximum mortgage isn’t just a simple income x rule, it’s a combination of a few key factors that lenders use to assess affordability.
They start with your gross income, then factor in your housing costs (like mortgage payments, property taxes, and heating), as well as any other debts you carry.
From there, they apply debt ratio guidelines (GDS and TDS) to make sure your monthly payments stay within a manageable range.
Interest rates also play a role in the calculation, which means your maximum approval can shift depending on market conditions.
That’s why two people earning the same income can end up with very different approval amounts, because it’s not just about income, it’s about the full financial picture.
If you’re curious what your actual maximum purchase price looks like, it’s always worth getting a personalized breakdown.
