Borrowing

Renteradar says it uses the loan amount, remaining term and repayment method to calculate effective interest, instalments, total interest costs and a full repayment plan. These calculations do not guarantee lender approval or savings.

Data Access

Borrowers can choose whether to enter their loan details by hand or have them pulled from their bank automatically. When the bank option is used, the service sees the same information the borrower sees after logging in with that bank, and it says it uses that access to retrieve loan data along with basic contact details. A login step confirms identity before anything is displayed. Information travels through encrypted channels, and the operating company is a Norwegian limited company.

Who runs the service

Renteradar is run by Hayon AS, which is the company behind the service. The service is built around mortgage holders who want a clear overview of their own loan and of what other banks provide. Its purpose is to make a home loan easier to understand, so that a homeowner can see where the current arrangement stands alongside other options. The team behind the service has real experience with home loans.

Focus on existing home loans

Renteradar sits in the home loan field, aimed at people who already hold a mortgage rather than at people looking for their first home. Its focus on existing loans sets it apart from broader consumer lending tools that also cover credit cards and personal borrowing. Homeowners who want one tool for reviewing their own loan will find the approach direct, while people who want help with a fresh purchase will need to look elsewhere. Moving a loan can be less complicated than many people expect, and the tool can direct attention to lenders where a move looks worthwhile.

Our full take

Renteradar helps Norwegian home owners compare mortgage rates and refinance their home loan.

How Renteradar compares

Frequently asked questions

Which alerts does the service send?+

The service sends an email when the terms of a mortgage change and when more attractive terms from other lenders appear. It also follows changes over time, so they can be seen as they happen. Borrowers can respond by negotiating with the current bank through the included tool, or by looking at moving the loan to a different institution where the change looks worthwhile.
