How much can refinancing save me?

A 0.5% rate reduction on a $500,000 loan saves about $1,850 per year. Over a 25-year loan, that's potentially $40,000+ in savings even after accounting for refinance costs.

What are the costs of refinancing?

Typical costs include: discharge fee from old lender ($150-400), application/establishment fee ($0-600), valuation ($0-300), and legal/settlement costs ($200-500). Many lenders waive fees or offer cashback to offset these.

Pro tips

Refinancing usually makes sense if you can save 0.25% or more AND have at least 2 years left
Many lenders offer cashback of $2,000-$4,000 to cover switching costs - factor this in
Wait until any fixed rate period ends to avoid break costs unless savings are massive
Your existing lender often matches competitors - use refinance quotes as negotiation leverage

Avoid these

Only looking at advertised rates - comparison rates include fees and give the true picture
Forgetting about fixed rate break costs which can be $10,000+ depending on market conditions
Not factoring in the cost of new valuations, legal fees, and settlement costs
Refinancing repeatedly and resetting to 30 years each time - you pay more interest overall
