Do variable mortgage payments always change with prime?

No. Adjustable-rate products usually change the payment when prime changes. Some variable products keep payments static for a time and change the interest/principal split instead.

Is a variable rate cheaper than fixed?

Not always. Variable can outperform in some rate cycles, but the result depends on rate movement, discount, timing, penalties, and whether the borrower can stay in the product long enough.

What is a trigger rate?

A trigger rate is the point where the scheduled payment no longer covers enough interest under the lender's rules. The lender may require a payment increase, lump-sum payment, or other adjustment.

Can I switch from variable to fixed?

Many lenders allow a conversion from variable to fixed, but the available fixed rate, remaining term options, and conditions depend on the lender and contract. Check the conversion rules before choosing variable.

Clients who understand the rate cycle and are not choosing variable only because the starting rate looks lower.

Static-payment variable mortgages may keep the payment level but change the principal-versus-interest mix.
If rates rise enough, a trigger rate or trigger point can force a payment change, lump-sum payment, or other lender action.
