"Can an Alaska Energy Rating Lower Your Mortgage Rate? What to Have Done, and When"

An energy rater is standing in the front doorway of a two-story home outside Palmer with a red nylon panel sealed into the frame and a fan set into the middle of it. The fan comes on, the home is pulled gently out of balance on purpose, and for the next few minutes every draft in the place gives itself away. The rater has already measured the walls, checked the attic and the crawlspace, and read the labels on the boiler and the water heater. All of it goes into a piece of software that only exists for Alaska, and the result is a star rating and a point score on a certificate. In Alaska, that certificate can change the interest rate on your mortgage.

Alaska Housing Finance Corporation lowers the rate on its home loans when the home carries a 5 Star Plus or 6 Star energy rating from an approved rater, or when you raise an existing home's rating after closing. The rater has to be approved by Alaska Housing, and the rating has to be in your lender's hands before the rate on your loan is set.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, licensed in fifteen states, including Alaska, NMLS #483943, through C2 Financial Corporation. I write about the state rules that move money and time on a home purchase, and this one in Alaska comes down to timing.

How does an Alaska energy rating lower my mortgage rate?

Alaska Housing Finance Corporation, which most Alaskans call AHFC or Alaska Housing, is the state's housing finance agency. It does not lend to you directly. It buys loans from a network of Alaska Housing approved lenders, and other lenders can offer its loans in partnership with one of them. Its programs carry add-on options, and this article is about the Energy Efficiency Interest Rate Reduction.

Alaska Housing lowers the interest rate on its loan when the home you are financing is more energy efficient than the standard, or when you make it more efficient. Its page says any property that can be energy-rated and is otherwise eligible for Alaska Housing financing qualifies.

The rating has to come from an Alaska Housing approved energy rater. A utility's online audit or a national score from another program does not count for this purpose. Alaska Housing keeps its own list of approved energy raters by community, and that is the list to work from.

The reduction applies to the first portion of the loan. Alaska Housing sets a dollar threshold, and the reduced rate applies to the loan amount up to it. The amount above it gets a blended rate, meaning the reduced rate and the regular rate are averaged together by how much of the loan falls on each side of the threshold. The program page notes that the threshold changed for loan commitments issued on or after October 1, 2024. A loan commitment is the lender's written agreement to make your loan on stated terms, so your lender quotes the figure that applies to yours.

Access to natural gas changes the size of the reduction. Alaska Housing publishes a larger reduction for homes without natural gas access than for homes with it, at each rating tier. I am leaving the percentages out on purpose, because they move, and your lender will show you how the current ones land on your scenario.

The three ways a home qualifies

Alaska Housing's program page splits the option into three paths, and the path you are on decides what you need to have done and when.

A newly built home that beats the state standard. Every home in Alaska that began construction on or after January 1, 1992 has to meet the Building Energy Efficiency Standard, called BEES, if Alaska Housing or other state financial assistance is used in the purchase. The minimum under that standard is 5 Star. A new home earns the reduction by rating above the minimum, at 5 Star Plus or 6 Star. So the question for the builder is which tier the home landed on, and whether the certificate is finished before you need it.

An existing home that already rates 5 Star Plus or 6 Star. Alaska Housing defines an existing property as one completed for more than one year or previously occupied. If the home already rates at one of those tiers, the certificate is the whole requirement on the property side. A rating can be on file from an earlier sale or from the owner's own project, so it is worth asking the seller directly whether one exists and how recent it is.

An existing home you intend to improve. Your lender notifies Alaska Housing at the time of application that you intend to participate. Then, within 365 days of closing, you have an initial energy rating done, complete the improvements, and have a final rating done. Within 30 days of that final rating, the documentation goes to your loan servicer, which is the company you send your monthly payment to after closing. The home has to move up at least one step on the star scale and gain at least 5 points.

The rating itself

An Alaska energy rating is a score on a one to six star scale, backed by a point score that runs from 0 to over 100. Alaska Housing's explainer, Understanding Home Energy Ratings, describes how a rater gets there. The rater measures the shell of the home, meaning the walls, ceilings, windows, garage, crawlspace and attic, and records the insulation at each one. Then come the heating and water heating systems and the blower door test, which is the fan in the doorway measuring how tight the construction is.

Every detail goes into AkWarm, the modeling software Alaska Housing released in 1996 and the only software used for ratings in the state, and it produces the certificate your lender needs.

The seller already owes you a written disclosure before you make a written offer in Alaska, so that is a natural moment to ask for the rating too. The Alaska seller disclosure covers what that document holds and when it arrives.

Getting the rating before the rate is set

The reduction is applied to the interest rate on an Alaska Housing loan, which means your lender needs the certificate in hand when the rate gets set. If the certificate shows up after that, the loan has already been priced without the reduction.

If I were sitting across from you looking at an Alaska home, this is the order I would work it in.

I would ask whether the home already has a rating before writing the offer. On new construction, that means asking the builder which tier the home was built to and when the final rating will be complete. On an existing home, it means asking the seller or the listing agent whether an Alaska Housing rating exists and when it was done.

If there is no rating and the home might qualify, you will want to book the rater during your inspection period. In many parts of Alaska the number of approved raters is small and travel is part of the job, so a rater's schedule can run longer than a home inspector's.

Your lender should hear at application that you want this option. On the improvement path, Alaska Housing requires the lender to notify it at application, so the plan has to be on the table from the first conversation. On the purchase paths, telling the lender early means the rate does not get set before the certificate lands.

The certificate goes to your lender as soon as it exists. Please provide the complete energy rating certificate, all pages, please. The star rating, the point score, the rater's name and the date are all on the full document.

Then you choose a rate option. Once the certificate is in the file, the lender can show you the loan with the reduction applied, and you can choose the option that works best for you. Your selection can still change until the rate is set. How rate locks work covers the general mechanics, and the Alaska Housing reduction comes on top of them.

If you are improving the home after closing, the clock matters. The 365 days run from closing, and the documentation has to reach the servicer within 30 days of the final rating. Winter can push exterior work to summer, and summer contractors book up, so the work has to fit inside those dates.

A home in a small community can carry the rural rate and the energy reduction together

The Rural Owner-Occupied program is an Alaska Housing loan for a home in a small community, which Alaska Housing defines by population and by whether the community is connected by road or rail to Anchorage or Fairbanks. Its rate applies to the first portion of the loan with a blended rate above that. The energy reduction is an option that the Alaska Housing program matrix carries across its single-family programs, with its own threshold. A home in a small community that also carries a qualifying rating can have both, and your lender works out how they stack.

Mistakes that cost Alaska clients the reduction

Assuming any energy audit counts. Only a rating from an Alaska Housing approved rater, run through AkWarm, qualifies. A utility's audit can help you decide what to fix, and it does not earn the reduction.

Finding out about the rating after the rate is set. A seller can have a recent certificate on file, and if nobody asks until the loan is already priced, it does not help the rate.

Mixing up the seller's improvements and your own. New windows the seller put in last year show up in the home's current rating, if the rating is recent enough to reflect them. Windows you plan to install after closing are the improvement path, and the lender has to know about that plan when you apply.

An example, with invented numbers

Numbers below are made up to show the sequence. They are not a quote, not a prediction and not a statement about any real property, and the rate amounts are left out because those come from your lender.

A client is buying an existing home outside Wasilla with no natural gas service, and the seller has no rating on file. Both versions start with a signed contract and a closing set 40 days out.

Nobody asks. The home inspection gets done, the loan goes to processing, and the rate gets set in the third week. In week five the client hears about the energy reduction from a neighbor, calls a rater, and gets a certificate showing 5 Star Plus. The loan was already priced without it.

The client asks first. The same client asks about a rating the day the contract is signed, learns there is none, and books an approved rater for the following week. The certificate comes back at 5 Star Plus on day nine, the lender has it on day ten, and the client chooses a rate option on day twelve with the reduction already in it.

The home, the rating and the closing date are the same in both versions, and the only difference is that the second client asked before the rate was set.

Your next step on an Alaska purchase

You can run your numbers first, with no credit pull, no account, and nobody calling you. You will see pricing for your own scenario, with closing costs figured for Alaska rather than a national average.

Once you are ready to make an offer a seller will take seriously, get pre-approved for an Alaska mortgage, which means income, debts and credit get reviewed rather than estimated. How an Alaska closing works covers recording districts and the title rules here, and how to read the septic record for every bedroom covers the other record worth reading early on a home with its own septic system. Buying a home with solar panels covers what a panel agreement does to your application, and what moves your rate explains the pricing underneath all of it.

You are also welcome to call me and talk it through before you book a rater.

Nothing here is a loan approval, a denial, a commitment to lend, or legal advice. Alaska Housing Finance Corporation's program documents are the authority on their own terms, and the reductions and thresholds in them change. No letter from anyone is a loan commitment, and final approval depends on the property, the appraisal and full underwriting.

Common questions

What is the AHFC Energy Efficiency Interest Rate Reduction?

It is an option on Alaska Housing Finance Corporation's home loan programs that lowers the interest rate when the home being financed carries a qualifying energy rating, or when you make energy improvements to an existing home after closing. The reduction applies to the first portion of the loan up to a threshold Alaska Housing sets, with a blended rate above it. The size depends on the rating tier and on whether the home has access to natural gas, and the current amounts come from your lender because they change.

What energy rating does a home need to qualify in Alaska?

For a purchase, the home needs a 5 Star Plus or 6 Star rating from an Alaska Housing approved energy rater. On new construction, 5 Star is the minimum under Alaska's Building Energy Efficiency Standard for a home financed with state assistance, so the reduction starts one tier above that. For an existing home you plan to improve, the rating has to go up at least one step on the star scale and gain at least 5 points between the initial rating and the final rating.

Who can do an energy rating in Alaska?

Only an energy rater approved by Alaska Housing Finance Corporation, using the AkWarm software that all Alaska ratings run on. Alaska Housing publishes a list of approved energy raters sorted by community on its website. An audit from a utility, a national energy score, or an online estimate can help you decide what to fix, and none of them earns the Alaska Housing rate reduction.

Does the energy rating need to be done before I lock my rate?

For a purchase, yes in practice. The reduction is applied to the interest rate on the Alaska Housing loan, so your lender needs the rating certificate in the file when the rate gets set. The improvement path runs on a different clock. The lender notifies Alaska Housing at application, and the initial rating, the work and the final rating all happen within 365 days after closing. The documentation then reaches the servicer within 30 days of the final rating.

Can I get the energy rate reduction on an Alaska Housing rural loan?

Yes. The Rural Owner-Occupied program is an Alaska Housing loan for a home in a small community, and the energy reduction is an option that Alaska Housing's program matrix carries across its single-family programs. Each has its own threshold and blended rate, and your lender works out how they stack on your loan.
