Staying is simplest: sign and continue.

The comparison should include the term, prepayment privileges and the penalty formula, not just the headline rate.

At maturity there is normally no prepayment penalty. Breaking early is different: variable-rate mortgages typically use three months' interest, while fixed-rate mortgages use the greater of three months' interest or an interest rate differential calculation that varies significantly between lenders.
If you bought in St. Thomas several years ago, you may have meaningful equity relative to your original purchase price. That opens options at renewal: shortening amortization, consolidating higher-interest debt, or funding a renovation on an older property — because you're already re-documenting the file.
Generally no, if you simply sign the renewal. Switching to a new lender or adding funds means qualifying, including the stress test with most federally regulated lenders.
About four months before maturity. That leaves room to hold a rate and complete a switch without rushing.
On a straight switch, many lenders cover or reimburse the standard legal and appraisal costs. That should be confirmed in writing for your specific file.
Yes, and it's one of the most effective ways to reduce total interest if the higher payment fits your budget.
A short conversation is usually enough to know what's realistic. No obligation, no pressure.
