Criteria
What Banks Check When You Apply for a Loan

Personal Criteria

When assessing a loan application, the focus is first and foremost on the borrower. Income and its stability are examined—that is, employment status, industry, work hours, and long-term sustainability. Closely linked to this is Affordability: How high are housing costs relative to income? Also relevant are equity and the borrower’s overall financial situation, as well as existing obligations such as loans, leases, or alimony payments.

As people get older, their retirement planning becomes increasingly important—especially after age 55, when banks begin to consider how a person’s financial situation will evolve after retirement. Savings habits and financial discipline are also factored into the assessment. Additional assets such as Pillar 3a accounts, securities, pension fund assets, or other real estate can significantly improve the rating.

The rule of thumb: The more stable and predictable your situation is, the better your rating tends to be.

Property Criteria

It’s not just the borrower who is evaluated—the property itself also has a significant impact on the terms. Key factors include location and marketability, condition and maintenance, as well as a realistic purchase price relative to the appraised value. Resale potential carries particular weight: standard properties in good locations are clearly preferred by most mortgage lenders, while luxury properties or collector’s items are often considered a risk that is more difficult to assess.
