What decreasing-term buyers should look for
- Match the interest assumption: if your mortgage is 5%, ask for a 5% decreasing schedule (default is often 6%).
- Match the term: add 1–2 years to your mortgage term to cover completion delays.
- Joint vs single: joint is cheaper but pays once.
- Indexation usually not needed on decreasing term (your mortgage isn't indexed either).
What to avoid
- Decreasing term for interest-only mortgages — the balance never falls, so level term is needed.
- Lender-recommended cover without comparison — typically 20–40% over-priced.
- Schedules with steeper decreases than your mortgage actually reduces — leaves coverage shortfall.
