What is affordability and why does it matter?
The affordability threshold is the percentage of monthly gross income that can be used for mortgage payments. Affordability is usually considered by lenders when deciding on loan approval.
How is affordability calculated?
Affordability is calculated by determining a buyer's available income after deducting monthly expenses. Generally the monthly mortgage payment should not exceed 33% of gross monthly income.
How can you increase affordability?
There are three main levers:
- Find a favourable interest rate
- Increase income
- Bring more equity
What do banks look at?
Banks consider not only financial factors but also individual life situations. Families with children have higher monthly expenses than childless couples. Make sure you can afford a home that meets your needs without endangering your financial stability.
