During pre-approval, you’ll have to choose between a fixed or variable mortgage rate. This decision affects how much you can borrow, your monthly payment, and even your approval odds. Knowing the differences helps you make a confident choice that fits your long-term goals.
Fixed mortgage rates
A fixed rate stays the same for your entire mortgage term, usually one to five years. Your payment amount never changes, which gives you predictability and peace of mind.
Pros:
- Steady payments that make budgeting easy
- Protection from future rate hikes
- Often preferred by first-time buyers
Cons:
- Usually higher than variable rates at the start
- Less flexibility to take advantage of falling rates
Variable mortgage rates
A variable rate can change whenever your lender’s prime rate moves. This means your payment or the amount going toward principal and interest may shift.
Pros:
- Lower starting rates
- Potential savings if rates drop
- Easier to switch or pay down faster with some lenders
Cons:
- Payments could rise if rates increase
- Harder to plan long-term budgets

How the rate type affects pre-approval
When lenders calculate your affordability, they use a stress test based on a qualifying rate that’s higher than your actual rate. For fixed mortgages, that’s usually the greater of 5.25% or your rate plus 2%. For variable mortgages, the same rule applies.
Even if variable rates are lower, the stress test can reduce your borrowing limit slightly compared to a fixed rate, especially if rates are volatile.
What to consider before choosing
- Your risk comfort level – Do you prefer predictable payments or potential savings?
- Market outlook – Are interest rates likely to rise or fall soon?
- Length of stay in the home – Fixed rates are ideal for stability, variable rates for flexibility.
- Prepayment options – Check if you can make extra payments or increase your monthly amount.
