The Myth of Expensive Sustainable Homes
Many banks and major mortgage lenders continue to make loan decisions based on the false assumption that better-built homes are an expensive luxury. FSC-certified tropical lumber could indeed be a costly addition to a new hardwood floor. But, other sustainable building elements make perfect economic sense.
For example, opting for ENERGY Star certified triple-pane windows or even Passive House grade windows would add a few thousand dollars to your home's price tag. Fortunately, these types of windows would help lower the heating requirements of the dwelling. In addition, it may allow you to opt for a smaller furnace and possibly less ductwork in new home construction. These savings would help offset a significant portion of the added cost of the windows.
Unfortunately, many mortgage lenders are not prepared or trained to take into consideration these immediate savings. Banks will often focus only on the initial upfront costs associated with home building or retrofits instead of looking at the larger picture of life-cycle costs. Sustainable homes are usually durably built, meaning that homeowners will most likely spend less on replacements and repairs over the lifetime of the mortgage.
How Do You Present Sustainable Upgrades To Banks?
Mortgage lenders tend not to be the most flexible institutions in the financial world. However, homeowners can use strategies to demonstrate to the bank the financial sturdiness of your plans to build or retrofit a sustainable home.
Firstly, make an effort to show the bank the potential savings associated with your building plan. You might even consider hiring a certified energy auditor or advisor to document the expected energy savings associated with the blueprint for your new home construction or sustainable retrofit. Your energy advisor will be able to identify certain rebates and incentives that are available to you. These rebates and incentives will further increase your expected monthly savings.
Secondly, consider utilizing a simple mortgage calculator to experiment with increased mortgage costs. You can then compare how these costs correspond to your expected savings through energy-efficient upgrades to your building plan. You may be able to convince your bank to offer a lower interest rate if you can demonstrate that the savings offset the higher monthly payments.
Show your bank how sustainable upgrades to your home will increase your home's value and help it maintain its premium price into the future. For example, a Berkeley Lab study demonstrated how solar panels add significant long-term value to a home.
Making our homes more efficient - and eventually getting to net-zero, is vital in our global fight against climate change. Experts in North America are looking to Europe and other parts of the world where this process is already well underway. Hopefully, many more financing options will be available soon, not just for those who are forward-thinking but for everyone. Soon, sustainable homes will be the norm!
