What is One-Room Investment Loan Refinancing?

For investment loans used for one-room investments, the available financial institutions and loan conditions may have changed since the contract was signed. By refinancing to a loan with a lower interest rate or better conditions, you may be able to reduce your monthly payments and total repayment amount.

"I don't know which financial institution to choose."

"I can't tell if refinancing is beneficial, even including the fees."

If you have concerns like these, please take advantage of our free consultation campaign via our official LINE. You can easily consult about refinancing simulations.

Three Features of "One-Room Investment Karikae-kun," which Supports One-Room Investment Loan Refinancing

1. Compare conditions from a network of 17 partner financial institutions

We compare refinancing options by utilizing a network of 17 partner financial institutions based on your current loan status, property, income, and other conditions.

We will provide the best conditions tailored to the current market and your borrowing situation, reducing the burden of researching and contacting each financial institution individually while proposing candidates.

2. Simulate not only interest rates but also fees

When refinancing, even if the interest rate decreases, you may not achieve sufficient benefits due to various costs such as administrative fees. Without checking the fees, it can be difficult to accurately assess the benefits of refinancing.

Our service's free consultation campaign provides concrete simulations including estimated fees and total repayment amounts.

3. Specialized support for one-room investment loans

Unlike residential home loans, refinancing investment loans is influenced by various factors such as property profitability, asset value, and the owner's borrowing status during screening.

This service utilizes expertise specialized in one-room investment loan refinancing, supporting everything from reviewing current conditions to completing procedures.
