After taking out my first mortgage, I consistently met the bank's conditions for a lower interest rate. I spent the required amount on a card, deposited my salary, and maintained enough automatic transfers.
It was one more thing to monitor, but I thought that was a fair price for lower interest. I kept doing it for nearly five years.
Checking transactions every month
Tracking card spending and transfers became a habit. If I failed to meet a condition, the discount could shrink.
The effort was not pointless. I really did receive lower interest charges while the benefit applied. Yet I paid much less attention to how long that benefit would last.
When I signed the mortgage, the initial rate mattered most to me. Five years felt far away.
What changed at the five-year mark?
As the rate reset approached, I reviewed the conditions more carefully. As I remember it, the agreed spread remained unchanged, but the transaction-based discount applied during the first five years expired. The reference rate was separately recalculated under the agreement.
That is not the same as saying the bank suddenly raised the spread outside the contract. The temporary reduction made the effective rate lower for a time; after it ended, the originally agreed spread applied without that discount.
Interest rates were also rising around the period as I experienced it. A rate reset and discount expiry together made the change feel much larger.
Why I felt as if I had been tricked
My initial reaction was strong enough that I felt as if I had been cheated. I had carefully met the requirements for years, only to learn that the benefit would no longer apply regardless of my effort.
But on reflection, I may well have been told about the limit at the beginning. It was my first mortgage and there was so much to learn. I had not translated the words about the discount period into a calculation of my future monthly payments.
Hearing a condition explained and truly understanding its financial effect are different things.
My surprise does not establish a breach of contract by the lender. I have not rechecked every clause of the original agreement, so this is a record of my experience, not an allegation of unlawful conduct.
What I wanted to check next time
Afterwards I wanted to know when discounts would expire, which formula would apply after that, and whether the discount required constant management of card and bank transactions.
If possible, I wanted a mortgage without those recurring obligations. That became an important factor when I considered a second mortgage.
