Comparing a 2.77% five-year fixed mortgage quote in Tokyo

I need to choose between lenders soon, and the trade-off is not as simple as taking the lowest displayed rate. One Tokyo quote is 2.77% with a five-year fix for a purchase around ¥48,960,000; fees and the relevant loan-to-value bracket make the other offers look closer than their advertisements suggest.

APR is tempting as a quick comparison, but I think the better measure may be total outlay through year five together with the balance remaining. That would also expose the cost of selling, repaying early or refinancing rather than assuming I keep the same loan.

My next step is to ask each lender for those figures using the same loan amount and exit date. Is there another refinance or early-repayment assumption that should be kept consistent?
 
Compare total cost over the period you realistically expect to keep that particular loan. For a five-year horizon, include upfront fees, five years of payments, any expected early-repayment cost, and the remaining balance at the end. APR can be a useful screening figure, but it may not reflect your actual exit date or flexibility needs.
 
Is ¥48,960,000 the purchase price or the amount you intend to borrow? That distinction matters because the loan-to-value tier could change with a larger down payment. Also, do you expect to own the property beyond five years, or is a sale or move reasonably possible before then?
 
I would not reduce this to one cost number. The bigger uncertainty is what happens after year five. Check what the rate resets to and whether your budget still works under a less favourable rate. A tiny monthly saving now can be outweighed by taking more reset risk later.
 
Be careful with the word “portability.” Ask the lender exactly what event it covers, whether a fresh affordability assessment would be required, and whether the same terms would carry over. A feature can sound valuable while being too conditional to rely on for an actual move.
 
The arrangement-fee comparison needs a break-even point. Divide the extra upfront fee by the monthly saving against the next-best offer. If the break-even date falls after the likely refinance, sale or repayment date, the lower advertised rate is not really cheaper for you.
 
I disagree slightly with using five years as the only comparison period. It is useful, but only if you also account for the balance remaining after five years. Two loans can demand similar cash payments while paying down principal at different speeds. Compare both cumulative cash outlay and outstanding balance on the same date.
 
Adding to my portability comment: ask for two separate illustrations—one where you keep the loan through the fixed period, and one where you repay early at your most plausible moving date. That should show whether the flexibility has real financial value rather than just reassuring wording.
 
Do not make refinancing the base assumption. Treat it as an option, because future rates, property value, lender criteria and refinancing costs may all differ. I would first test whether the post-fix payment is manageable without refinancing, then regard any successful refinance as an improvement on that case.
 
A simple spreadsheet should make this clearer. Give every offer the same loan amount, start date and comparison dates. List the initial cash contribution, lender fees, monthly payments, optional repayment costs and balance at each exit date. Then add a separate column for non-price terms such as portability. That prevents a flexible but slightly dearer loan from looking automatically inferior.
 
Yes, the remaining balance point is important. By “total cost” I meant fees plus interest and other non-principal charges, with principal tracked separately. Otherwise counting every payment as a cost can distort the comparison. I would run at least an early-exit date and the full five-year date.
 
The loan-to-value threshold may be the lever worth examining. Ask how much additional cash would be needed to enter the better tier, then compare that with the interest and fee saving. Even if the tier is cheaper, tying up more cash may not suit you if it leaves too little reserve after purchase.
 
I would send each lender the same short list of written questions: exact upfront cash due, whether fees are added to the loan, treatment of partial and full early repayment, rate-setting after five years, and what portability actually permits. Comparable answers are more useful than trying to reconcile differently presented advertisements.
 
Since the monthly difference is small, I would choose using three tests: affordable after a rate reset, sensible total cost at your likely exit date, and acceptable restrictions if plans change. If one offer wins only under a perfectly timed refinance, that is a fragile advantage. Flexibility is worth paying for, but only after confirming the terms are genuinely usable.
