Optimize your mortgage in one afternoon

A 0.4% rate cut on a 3 MSEK mortgage saves ≈ 12,000 SEK per year — for 25 years. Here is the exact script that gets banks to move.

Optimize your mortgage in one afternoon

Your mortgage is almost certainly the single largest contract in your life. A small rate change compounds into six-figure differences over a 25-year horizon. Yet most households never renegotiate after the initial signing — they let inertia cost them more than any investment decision they will ever make.

Banks know this. Their entire retention model is built on the assumption that you will not call. The hour you spend on this is, statistically, the highest-paid hour of your year.

Step 1 — Pull three real, written offers. Go to two banks where you are not currently a customer and request a written rate proposal based on your loan-to-value ratio (LTV). Do it digitally; most banks respond within 48 hours. Add the public floor rate from a niche or digital-first lender as additional leverage. Three offers is the minimum — one is a data point, three is a market.

Step 2 — Never negotiate over the phone. Send the offers by email or your bank's secure message. Open with one sentence: "I would like the opportunity to keep my business with you — please match or beat the lowest of the attached offers within 3 business days." Phone calls let an advisor talk you out of competing offers in real time. Writing forces them to escalate it to someone who can actually move the number.

Step 3 — Be visibly willing to move. Banks read your tone. If you sound like a bluffer you get a token 0.05% cut. If you have already started the bank-transfer paperwork — even just downloaded the forms — the counter-offer typically arrives within hours. Your willingness to leave is the only real leverage you have.

Step 4 — Re-amortize, do not just re-rate. While the bank is paying attention, also ask whether you can shorten the amortization period without raising the monthly payment (often possible if your income has grown). Cutting 5 years off a 30-year schedule can save more than another 0.2% rate cut.

Common mistakes: • Calling instead of writing — instant loss of leverage. • Accepting the first counter — banks almost always have 0.1–0.2% more to give. • Confusing the listed "list rate" with the negotiated rate — you are entitled to the latter. • Forgetting to repeat next year. A rate hard-fought in 2026 quietly drifts upward by 2027 if you do not check.

What success looks like: Your new written rate is at least 0.2% below your old one, the change confirmed in writing, and a calendar reminder is set 12 months from today.

Checklist: • Loan-to-value ratio calculated and on hand • 3 written competing offers obtained • Email sent to current bank with a 3-day deadline • Amortization length reviewed in the same conversation • Calendar reminder set for 12 months from today to repeat
