Key takeaways

  • An energy-efficient mortgage, or EEM, can help you pay for an energy-efficient home or for energy-saving upgrades to a home.
  • An EEM can cover improvements such as installing energy-efficient appliances, doors and windows or replacing a furnace or water heater with a more energy-efficient model.
  • Depending on how much the improvements cost, the property might require an energy assessment in order to qualify.

What is an energy-efficient mortgage (EEM)?

An energy-efficient mortgage (EEM) is a loan for purchasing or refinancing a home that meets certain energy-efficiency requirements, or for improving a home to make it more energy-efficient.

An EEM can be a conventional loan, an FHA loan or VA loan. As with other types of mortgages, the home serves as collateral for the loan.

Mortgage
Some banks, credit unions and other types of lenders offer their own energy-efficient mortgages. The EEMs in this guide cover loans backed by Fannie Mae, Freddie Mac, the Federal Housing Administration and the U.S. Department of Veterans Affairs.

How does an energy-efficient mortgage work?

You can use an EEM alongside another mortgage, such as a conventional loan or renovation loan, and depending on the type of EEM, can borrow up to 15 percent of the home’s appraised value to make energy-efficiency improvements.

When assessing an applicant for an EEM, a mortgage lender considers how much money the borrower stands to save on utilities by either buying or refinancing an energy-efficient home or making energy-efficiency upgrades. These estimated savings are determined through an energy assessment, and can help you qualify for a larger loan, since the savings free up more in your budget for a mortgage payment.

If your lender allows it, you might be able to do some of the renovation work yourself to save money, but you can’t pay yourself — you can only use the EEM funds to pay contractors or for materials. You’ll have a certain amount of time to hire contractors and complete the improvements after the loan closes, usually three to six months.

Once the improvements are finished, your lender will order an inspection of your home to verify that the improvements have been made and are in fact increasing the home’s energy efficiency.

Energy-efficient mortgage requirements

If you’re planning to buy a home or refinance, you’ll need to qualify for a regular mortgage or refinance first. This means meeting credit score, debt-to-income (DTI) ratio and down payment requirements specific to the type of loan you’re getting.

Then, you’ll apply for the EEM, which will be on top of your regular mortgage. You might have to meet additional credit and documentation requirements. The most important is to obtain an energy assessment, in which an energy consultant examines the home and draws up a Department of Energy (DOE) Home Energy Score Report, a Home Energy Rating System (HERS) report or other comparable report. This report contains information about potential improvements, their cost and how much they’ll save.

The energy assessment isn’t free — about $400, on average, according to HomeAdvisor — but you might be able to finance the cost of the report with your loan. You can find a local professional to do the assessment through the DOE or HERS websites.

You’ll typically have three to six months to complete the improvements once your loan closes.

Acceptable energy-efficiency upgrades

You can only use an EEM for certain improvements. These are some of the acceptable upgrades:

  • Energy-efficient appliances
  • Energy-efficient doors and windows
  • Furnace or water heater replacement
  • Caulking or weather-stripping
  • Insulation
  • Solar panels

Energy-efficient mortgage options

There are different energy-efficient mortgage programs based on loan type. Here are the options:

Conventional energy-efficient mortgage

Conventional EEMs, including the Fannie Mae HomeStyle Energy loan and Freddie Mac GreenCHOICE Mortgage, allow you to borrow as much as 15 percent of the home’s appraised value to make energy-efficient improvements. If you’re buying or refinancing a home, this is on top of whatever loan amount you obtained for the purchase or refi.

A conventional EEM might also allow you to finance improvements to safeguard against natural disasters and storms, or pay off a Property Assessed Clean Energy (PACE) loan, another kind of energy-efficient home improvement loan.

A conventional EEM works just like a conventional loan and comes with similar requirements, such as a minimum down payment of 3 percent and a debt-to-income (DTI) ratio of no more than 45 percent. It can have a 15- or 30-year term or other duration, and a fixed or adjustable rate.

The Fannie Mae HomeStyle Energy loan doesn’t require an energy assessment if you’re making up to $3,500 in simple “weatherization” upgrades, such as installing insulation or a programmable thermostat, or making environmental or natural disaster repairs or protective upgrades. For the Freddie Mac GreenCHOICE program, that threshold is $6,500.

FHA energy-efficient mortgage

The Federal Housing Administration insures several types of mortgages, including the FHA EEM, which can come in a 15- or 30-year term and with a fixed or adjustable rate. With an FHA EEM, you don’t need to qualify for the additional funds that’ll go toward energy-efficiency improvements, but you do need to qualify for the FHA loan for the purchase or refinance first. When buying a home, this includes making a down payment of at least 3.5 percent.

With an FHA EEM, the improvements you make have to be “cost-effective,” meaning that the cost of the upgrades can’t exceed the energy savings they’d yield over their lifespan. Given this, the amount you can borrow for energy-efficiency improvements, according to the FHA, is the lesser of:

  • The cost of the improvements based on the energy assessment; or
  • The lesser of 5 percent of the home’s value; 115 percent of the area median single-family home price; or 150 percent of the conforming loan limit

VA energy-efficient mortgage

The U.S. Department of Veterans Affairs also backs energy-efficient mortgages. These are available to eligible military service members, veterans and surviving spouses, and provide up to $6,000 for energy-efficiency improvements on top of the VA loan for a purchase or refinance. You might have the option to obtain more than $6,000 with a VA EEM, but this isn’t as common, as you’ll need approval from both the VA and the lender to do it.

If the cost to make the improvements is $3,000 or less, you won’t need to do an energy assessment, but will need to provide contractor estimates. As with other types of EEMs, the projected savings from the energy-efficiency improvements need to outweigh the costs.

If you get a VA EEM, you also have to complete the improvements within six months of closing the loan.

Energy-efficient mortgage lenders

You can get an EEM through many of the same lenders that offer mortgages, including banks and credit unions. If you’re already working with a bank to get a mortgage for a purchase or refinance, ask about whether it offers EEMs.

Many states also facilitate programs for green mortgages, and your state housing finance agency might be able to direct you to lenders that offer EEMs. You can find your state’s housing authority in this Bankrate guide.

Alternatives to an energy-efficient mortgage

If you want to make energy-efficiency improvements to your home but need to borrow more than you can get with an EEM — or don’t want to deal with the process of an energy audit — here are some other options:

  • Cash-out refinance: If you’ve owned your home for a while, you might have significant equity in the property that you can leverage for home improvements. Generally, a cash-out refinance is a good idea if you can afford the closing costs, lower your interest rate and use the funds to add value to your home or make headway with other financial goals.
  • Home equity loan: A home equity loan functions similarly to a mortgage, allowing you to borrow money in a lump sum — with your home as collateral — and comes with a fixed rate and a term of up to 30 years. You can use the money for almost anything, including energy-efficiency upgrades.
  • Personal loan: Personal loans are more expensive than home equity loans and mortgages in general, but they don’t rely on you having equity in your home and don’t put your home on the line as collateral. They’re also highly flexible, so you can use them to make home improvements. Many lenders won’t let you borrow large amounts, however, which could make it difficult to finance more expensive energy-efficiency improvements like solar panels.

Is an energy-efficient mortgage right for you?

EEMs are best for homeowners who want to reduce their energy costs in the short run and increase their home’s value in the long run. Given the tight borrowing limits, EEM refinances are also better for homeowners who don’t need to take out a significant amount of equity at once.
