Blend-and-extend mixes your current rate with today’s rates into one new rate and a longer term — no lender switch, no legal bill.
When it wins
- You need relief now and can’t wait for maturity.
- The blended rate beats any competitor’s offer after switch costs.
- You value simplicity over squeezing the last 10 bps.
When it’s a trap
- The “blend” barely discounts while re-locking you for 5 more years.
- A competitor’s switch offer nets lower all-in cost within a year.
- You plan to sell soon — a fresh 5-year IRD tail is expensive.
