Comparing a 3.10% five-year fixed mortgage quote in Oslo

[AmberPost]

I’ve checked the headline rate, arrangement fee and overpayment terms, but I’m still unclear about the fairest comparison period. The quote is 3.10% fixed for five years on an Oslo purchase around NOK 11,720,000, and the loan-to-value tier appears to matter as much as the advertised pricing.

Should I compare the offers using all payments and fees over those five years, while also showing the principal remaining at the end? I also need to test the monthly payment against our actual budget rather than focusing only on total cost. My next step is to request the written conditions for portability and early repayment, then compare them with how likely we are to move or overpay during the fixed period.

I would compare both offers over the same five-year cash-flow period: upfront fees, scheduled payments and the remaining principal at the end. APR is useful, but it may reflect assumptions extending beyond your fixed period. Keep the overpayment and exit provisions beside the numbers rather than trying to assign them an arbitrary value.

How much are you actually borrowing, and how close are you to the next loan-to-value tier? On a purchase of NOK 11,720,000, a change in deposit could potentially alter the rate category and make the fee comparison secondary. Also, do you realistically expect to move or make large overpayments within five years?

Ask each lender for written illustrations of three scenarios: hold for all five years, repay after two years, and sell after three. Fixed-rate early repayment can depend on the contract and circumstances, so a generic statement that it is “allowed” is not enough. You need the method used to determine what you would owe.

I wouldn’t dismiss APR so quickly. It is the best first filter because it forces at least some fees into the comparison. A custom five-year spreadsheet can look more precise while still being wrong if the repayment timing or fee treatment differs between quotes. Start with APR, then investigate why the ranking changes under your five-year calculation.

The expensive fee may be buying flexibility you never use. I’d estimate the maximum plausible overpayment rather than the maximum permitted one. If normal monthly affordability already leaves little surplus, generous overpayment terms have limited practical value.

Portability also needs a more specific question: can the fixed loan move to another property, or does a move end the agreement and require a new affordability and loan-to-value assessment? Even if transfer is possible in principle, the replacement property and borrowing amount may not match neatly. Get the process and consequences described in writing.

 

[daily_sparrow]

Don’t compare only the fixed period. What would the monthly payment look like after year five under a meaningfully higher reset rate? You cannot know that future rate, but you can test whether the purchase still feels manageable. Refinancing should be treated as an option, not as the plan that makes today’s numbers work.

Is the 3.10% figure the nominal fixed rate or the effective rate after the quoted costs? That could explain why the advertisement and offer appear inconsistent. I would also confirm that the rate is tied to your current loan-to-value rather than dependent on a larger deposit or another condition.

 

[sketchesAndEcho]

That is why the actual borrowing amount matters. Two buyers paying NOK 11,720,000 can receive materially different comparisons if their deposits place them in different tiers. Oscar should ask for each offer to be rerun using exactly the same loan amount, repayment schedule and fee-payment method; otherwise the headline rates are not directly comparable.

 

[alba_finance]

Agreed on matching the assumptions. I’d add one affordability test using the real monthly payment, including any fees financed into the loan, and another after the five-year reset. A low total cost is not automatically the better choice if the payment pattern leaves no room for repairs, moving costs or ordinary surprises.

 

[watchTheCairn]

There is also a genuine trade-off between certainty and flexibility. If staying for five years is highly likely, the lower five-year cash cost deserves more weight. If a move, sale or major repayment is plausible, the quote with the painful fee might still be rational—but only if its better terms produce a clear advantage in one of your realistic scenarios.

I’d reduce this to a one-page comparison: same opening balance, same amortisation, all upfront and recurring fees, monthly payment, principal remaining after five years, and costs under early-sale scenarios. Then list portability and overpayment terms separately. Before choosing, ask both lenders to confirm the 3.10% basis, the applicable loan-to-value tier and the early-repayment calculation in writing.
