Tokyo mortgage quote: comparing 4.13% fixed for two years with fees

I want a predictable monthly payment on a Tokyo purchase of roughly ¥126,200,000, but the quote does not make the trade-off easy to judge. It offers 4.13% for a two-year fixed period, while the fees and applicable loan-to-value band make the headline figure a poor guide on its own.

My instinct is to compare the payments and all lender charges over 24 months, together with the balance still outstanding at that point, rather than rely on APR alone. Is that the right basis if I may refinance after the fix? I also need to check the lender’s illustration for the post-fix rate, portability conditions and early-repayment charges, as any of those could outweigh a small difference in the initial payment.
 
Compare total cost over the period you realistically expect to keep this loan, not just the advertised rate. For a two-year comparison, include upfront fees, 24 payments and the balance remaining after month 24. Two offers with similar payments can leave you owing different amounts.
 
What are the full mortgage term, repayment structure, fee amount and quoted loan-to-value band? Without those, 4.13% alone says very little. Also ask what rate or calculation applies immediately after the fixed period.
 
I would not make APR the only deciding figure here. If it is calculated across the full term using assumptions about the post-fix rate, it may hide the cost of a short two-year deal. A side-by-side cash-flow sheet is easier to interrogate.
 
I partly disagree with focusing only on the first 24 months. That works if refinancing after two years is genuinely feasible, but it can make an expensive reset look harmless. Run both a two-year case and a stay-with-the-lender case.
 
Also, treat refinancing as an option rather than the plan. Future approval, valuation, loan-to-value and fees are all unknown today.
 
Portability sounds attractive, but the useful question is what it actually permits. Does moving the loan require a fresh affordability decision or property approval? Does it preserve the 4.13% period, and can the amount change? Get the conditions in writing rather than assigning portability a monetary value now.
 
For affordability, calculate the payment at 4.13%, then repeat it at higher assumed rates after year two. The missing mortgage term matters a lot, so nobody can sensibly assess the monthly burden from the purchase price and rate alone.
 
Diego’s question about the fee is crucial. Check whether it is paid upfront or added to the balance. If financed, it affects both the initial debt and later interest, so listing it as a one-off cost understates its effect.
 
I would make four columns for each lender: cash needed at completion, monthly payment during the fix, balance after two years, and cost to exit at that point. Then put portability and other conditions underneath as notes rather than trying to force everything into one percentage.
 
Would a larger deposit move the quote into a better loan-to-value tier? If so, compare the actual saving against the extra cash tied up. A lower rate is not automatically worth using substantially more of your available funds.
 
Yes, and use the same loan amount when comparing lenders first. Otherwise the rate comparison becomes mixed up with the deposit decision. After identifying the better quote on equal terms, test whether changing the loan-to-value improves it enough to matter.
 
Early repayment needs splitting into partial overpayments and full redemption. A loan may treat them differently. Ask for the charge during the two-year fixed period, after it ends, and in any portability scenario. The timing could change whether refinancing or selling is economical.
 
Another missing detail is how the rate resets. Ask for the exact contractual mechanism, not merely an illustration of a future payment. You need to know what can change and when before modelling the longer holding case.
 
Agreed. I would build three scenarios: repay or refinance at two years, remain for several more years after a moderate reset, and remain after a more severe reset. They do not need to predict rates; they show whether the household budget has enough room if the preferred exit is unavailable.
 
One refinement to my earlier answer: subtract principal repaid when comparing borrowing cost over 24 months. Total payments alone can mislead because part of each payment reduces the balance. Fees plus interest and exit charges are costs; principal repayment is equity.
 
That distinction also helps compare a quote with a different repayment schedule. Still keep total monthly cash outflow visible, because an economically cheaper loan can be unaffordable if its required payments are badly timed for the borrower.
 
Have you asked the lender for a full payment schedule through the reset date? That should let you verify the 24-month interest, principal reduction and remaining balance rather than reconstructing everything from the headline rate.
 
Once you have that, ask each competing lender to quote on the same purchase price, deposit, term and repayment basis. If one cannot match the assumptions, mark the difference explicitly. Otherwise the advertised rate, loan-to-value tier and fees keep moving at the same time.
 
My decision sheet would therefore have two outputs, not one: the cost if you leave after two years and the cost plus monthly payment if you cannot leave. Then separately record early-repayment restrictions and portability conditions. That should expose what, if anything, the apparently lower advertised rate was omitting.
