Energy efficient mortgages can be utilized for which of the following purposes?

Energy efficient mortgages are designed specifically to promote and facilitate energy-saving improvements in residential properties. This type of mortgage allows borrowers to secure higher borrowing limits because it includes the financial costs associated with energy efficiency upgrades.

For instance, when a buyer is purchasing a home or refinancing an existing mortgage, they can use the additional funds provided through an energy efficient mortgage to implement energy-saving improvements such as solar panel installation, energy-efficient windows, or enhanced insulation. This not only helps in making the property more energy-efficient but can also lower long-term utility costs for the homeowner, making it a beneficial investment.

Utilizing energy efficient mortgages specifically for repairs or solely on new home purchases would not capture the full scope of their intended purpose. These mortgages are not just restricted to new homes or basic repairs; instead, they aim to encourage comprehensive improvements that make homes more sustainable and reduce energy usage. Thus, the understanding of energy efficient mortgages as tools for both raising borrowing limits and financing energy-related enhancements solidifies why this answer is correct.
