Oeko Mortgage

Definition
Eco-Mortgage

An eco-mortgage is a mortgage that offers a reduced interest rate compared to the official, non-negotiable for properties that meet certain environmental standards.

Typical requirements are as follows:

  • energy-efficient construction
  • sustainable Renovation
  • often in combination with a certification (e.g., or )

The eco-mortgage is not a separate but is usually a traditional model (e.g., Fixed-rate mortgages or Saron mortgages) with a discount on the benchmark interest rate.

Pros and Cons of the Eco-Mortgage
What You Need to Know

Benefits of Sustainable Mortgages

  • Sustainable living and energy savings
    Main advantage

    Those who build or renovate in an eco-friendly manner reduce energy consumption, lower ancillary costs in the long term, and increase property value at the same time. This goal is achieved regardless of whether or not an eco-mortgage is taken out.

  • Interest rate discount on the Mortgage

    Many providers offer an interest rate discount of approximately 0.1% to 0.3% off the published, non-negotiable benchmark rates.
    Depending on the Mortgage, this can amount to several thousand francs.

  • A Future-Proof Investment

    Sustainable real estate is in higher demand on the market, is less affected by regulatory risks, and retains its value more consistently over the long term.

Disadvantages of sustainable mortgages

  • Discounts are often smaller than expected
    Main drawback

    The advertised interest rate advantage is often less significant than it seems, as it typically applies only to a portion of the Mortgage, is time-limited, and is based on mortgage rates that are sometimes inflated . As a result, the actual benefit is often smaller than expected.

  • Higher investment costs

    Sustainable construction or renovation requires higher initial investments, additional planning, and certification costs.

  • Often not the best solution

    A standard can be significantly cheaper than a discounted green mortgage. The environment doesn’t care whether your Mortgage was sold to you as a green Mortgage or a standard Mortgage.
