Mortgage refinancing providers
Eligible balances, terms, fees, appraisal, and insurance for refinancing.
Most major and online banks and PRESTIA offer refinancing; compare the new rate against the full switching cost — origination fee, cancellation and registration, judicial scrivener, appraisal, and new insurance — over your remaining term.
Key points
- Major banks, online banks, and PRESTIA all offer refinancing.
- Compare the new rate against origination, registration, judicial-scrivener, appraisal, and insurance costs.
- Refinancing needs fresh group credit life insurance and health screening.
- A meaningful balance and remaining term are needed for savings to beat the fees.
Who offers refinancing and how to compare
Most major banks, online banks, and specialist lenders such as PRESTIA (which offers purchase and refinance uses up to ¥500 million with no guarantee fee) will refinance an existing mortgage subject to fresh underwriting. Because a refinance replaces the whole loan, compare the new rate against the full switching cost — a new origination fee, the old mortgage’s cancellation and the new registration, judicial-scrivener costs, appraisal, and new group credit life insurance — measured over your remaining term. A meaningful remaining balance and term are needed for the savings to exceed those costs.
Check the break-even before you switch
Refinancing pays only when the discounted present-value interest saving exceeds every new cost, so run the break-even before you apply: how many months of lower payments it takes to recover the switching costs, and whether you will hold the loan that long. Obtaining permanent residence or a stronger credit record can broaden the lenders available to you and improve the rate, but approval is never guaranteed, and a new loan means a fresh health screening for group credit life insurance — poor health can restrict standard cover, though wider-acceptance products may exist at a higher cost. Beware term extension: stretching the loan back out lowers the monthly payment and can make a refinance look attractive while raising the total interest, so compare like-for-like remaining terms and treat a lower monthly payment achieved by re-lengthening the loan as a cost, not a saving.
