The short version
- Green home loans offer lower rates on energy efficient homes or upgrades.
- Lenders use energy ratings like NatHERS, or a list of approved upgrades.
- Check your state's rebates for solar and batteries too.
What green home loans cover
A lower rate for homes with a high energy rating, or a loan to add solar panels, batteries, heat pumps and other upgrades. Each lender sets its own rules on what qualifies, such as a new home's energy star rating or a list of eligible upgrades.
Check the rate after any discount ends, and look for state rebates and interest-free loans for solar and batteries too.
Pros
- A lower rate than the lender's standard loan.
- Lower power bills from an efficient home.
- Some loans cover upgrades like solar and batteries at the same rate.
Cons
- Only for homes or upgrades that meet the lender's rules.
- The discount may be small or time limited.
- Few lenders offer them, so compare with standard loans too.
Alternatives
- A green personal loan, for upgrades on your current home.
- Government rebates and interest free state loans for solar and batteries.
- Refinancing your current loan, if you already own a home. A lower rate on your existing loan can save more than a new product.
How to apply
Most people get pre-approval for a green home loan before they start making offers, then the full approval once they've found a home.
- Get your documents together. Payslips, two years of tax returns if you're self-employed, bank statements showing your savings, and details of your debts and credit limits.
- Get pre-approval. It tells you how much you can borrow and shows sellers you're serious. It usually lasts three to six months.
- Find the home and sign the contract. The lender then values the property before it gives full approval.
- Settle. Your lender pays the seller, and your repayments start about a month later.
- Have the home's energy rating or the installer's quote ready, so the lender can check it qualifies.
What to compare
Start with the rate for your situation: the rate a lender offers depends on whether you'll live in the home or rent it out, how you repay, and the size of your deposit. The comparison above picks each lender's rate for your choices.
Then look past the rate.
- Fees: upfront fees, and annual package fees that often come with an offset account.
- Features: an offset account, redraw, extra repayments and the option to split the loan between fixed and variable.
- The comparison rate, which adds standard fees to the rate for an example loan of $150,000 over 25 years.
- Any cashback, but only after the rate and fees, since a higher rate can cost far more over the life of the loan.
