Last updated: About 2 min read

When choosing a home loan for a real estate purchase, online banks have become increasingly prominent in recent years. Their biggest feature is lower interest rates than megabanks and regional banks, but borrowers also need to understand differences in screening standards and procedures before making a decision. This article organizes the advantages and disadvantages of online bank home loans.

Why are interest rates on online bank home loans lower?

Because online banks do not operate physical branches, they can significantly reduce personnel and branch maintenance costs. They return those savings to customers in the form of lower interest rates. Examples of variable rates (as of 2022):

  • auじぶん銀行:0.31%
  • SBI住信ネット銀行:0.44%
  • ソニー銀行:0.457%
  • イオン銀行:0.47%
  • 楽天銀行:0.537%

When comparing 30 million yen over 35 years with equal principal-and-interest repayment, even a 0.05% difference in interest can create a gap of about 300,000 yen in total repayment, so even small rate differences can have a major long-term impact.

Advantages of online bank home loans

Lower rates can reduce total repayment

Compared with megabanks and regional banks, interest rates are lower, making it possible to substantially reduce the total interest burden on a long-term loan.

Comprehensive ancillary services

To strengthen competitiveness against other providers, many banks offer robust ancillary services at no extra cost, such as cancer coverage, full illness protection, and no-fee early repayment.

The process can be completed without visiting a branch

All procedures can be completed by phone, email, and mail. This is a significant advantage for people who are busy with work or childcare.

Preliminary screening is fast

Some banks can provide preliminary screening results as soon as the same day (formal screening usually takes about one to two weeks).

Disadvantages of online bank home loans

Screening is rigid and strict

Because there is no face-to-face consultation, screening is conducted mechanically based on documents alone. Factors such as personal background, reasons for changing jobs, and the context behind income fluctuations are not taken into account, so there are cases where approval rates are lower than at megabanks.

Product details are complex and hard to understand

Because campaigns and product offerings change almost every month, gaps in understanding can easily arise between sellers and users, leading to cases of regret afterward.

No in-person individual consultation

You cannot directly confirm questions about how to complete documents or about specific procedures. If documents are incomplete, additional time and effort are required to send them back and forth by mail.

Who are online bank home loans suitable for?

  • People with stable income and employment history who are confident they can pass screening
  • People who want to keep total repayment as low as possible
  • People with strong digital literacy who can proceed on their own judgment
  • People who do not have time to visit a branch

Frequently Asked Questions (FAQ)

Q. Is screening for online bank home loans stricter than at megabanks?

A. Because there is no face-to-face holistic assessment and screening is mechanical, people who have just changed jobs or whose income is unstable may find it harder to be approved.

Q. Could variable rates at online banks rise in the future?

A. Yes. Because variable rates are linked to the Bank of Japan's policy rate, there is a risk that repayment amounts will increase in a rising-rate environment. It is important to confirm your risk tolerance based on the loan amount, repayment period, and room in your household budget.

Q. Is no branch visit required at all when taking out a home loan with an online bank?

A. Many online banks do not require branch visits, but some procedures may still require documents to be sent by mail. Please confirm each bank's process in advance.

Q. Is group credit life insurance (団信) also comprehensive at online banks?

A. Yes. To strengthen competitiveness, online banks often provide extensive services at no extra cost, including 50% cancer coverage and full illness protection. We recommend comparing the details offered by each bank.
