Compare Fixed-Rate vs Tracker Mortgage at Renewal

Your deal is ending and the lender wants an answer: fix the rate or track the base rate. This works through the trade-off in plain terms, no regulated advice, so you understand what each choice exposes you to. Give your balance, the years left, and how you read the rate environment, and get a structured comparison to decide on.
