Using the Appraisal Addendum to Increase the Value of your Certified Home

I think you would all agree with me if I said communication bridges gaps, improves performance and, in general, good communication usually results in a more positive experience for all parties involved.

When I think of building a home I think of the many opportunities I am given to communicate with the client, the subcontractors, the suppliers, the designers and the sales team. Each communication takes us one step closer to successfully building the homeowner a certified green home they will proud to live in. Imagine if we chose not to communicate enough. How would that experience be? We do not want to go down that road except to ask ourselves who else we could communicate with to improve the experience. The answer is banks and appraisers.  

Fortunately we now have a tool to help us communicate with banks and appraisers and speak their language, if you will. That tool is the Residential Green and Energy Efficient Addendum, created by the Appraisal Institute.  This AI Form 820.04 is proof that industry is evolving and that valuing green and energy efficient homes is on the Appraisal industries radar. It has long been believed that homebuilders and home buyers have zero control over which appraiser arrives to value their home.  Likewise, we have been told by the bank that they cannot communicate directly with appraisers. Let’s dig a little deeper to see what is possible and identify steps to using this valuable tool in our favor.

First, we need to understand how appraisers are selected and how to assure the right appraiser arrives at your certified home. The bank does not and cannot decide who appraises a home. This is done by a selection process that is out of their and your control. What they can do is request an appraiser who has experience evaluating green certified homes or who is “competent in the subject matter”.  This should be step one in our communication with the bank. So, now that the bank knows we have a simple request the next step is to ensure the selected appraiser really is competent and knowledgeable about certified green homes. This step is real easy, interview the appraiser before the work begins. Trust me, appraisers want to be assigned jobs within their comfort zone and competency level. Once you have found an appraiser with the experience required it is now time to communicate fully with them.

This communication with the appraiser involves completing AI Form 820.04, the Residential Green and Energy Efficient Addendum, and providing a copy to the bank, appraiser and sales team.  A few items to note when completing the form are:

  • It should be completed by a knowledgeable person. As the builder I will often complete parts of it but I send it to the 3rd party green verifier, home energy rater and/or the solar installer for specific details about energy savings, HERS scores, envelope tightness, azimuth of an array and other technical information requested in the form. I ask them to sign that they have completed the form. This lets they appraiser know that a licensed professional has performed the energy modeling and verification work.
  • For construction to perm projects or other pre-construction loans be sure to use the comments sections to note “Proposed New Construction” as the work will not be done yet. In this case it is best to provide an “as built” addendum at the end of the project.
  • Attach the Green Certification and/or the Energy Certification to the addendum.
  • Attach other forms provided the Home Energy Rater and/or solar installer that share information about the HERS score and annual energy savings.
  • Use the comments section to identify costs for the appraiser. 
  • The form is not limited to certified homes. It can be used to identify saving associated with solar arrays, solar thermal, water efficiency, etc.

To conclude I want to remind myself and you that this form is no magic potion for insuring we get the proper value assigned to our certified homes. It is, however, one great tool we can use to assist in the process. The Appraisal Institute did a very thorough job in designing this document. The information requested is straight forward and is exactly the kind of information we need to be getting to the appraiser. Imagine if this form became a standard attachment to every build contract, every set of builder specification, and every home loan. If it was pretty soon bankers, underwriters, and appraisers would know more about green building, insulation types, ACH50, passive solar, HERS scores, energy saving, solar arrays, etc. Isn’t this what we all want? Communication is the key to successfully building a great home and it will also be key in continuing to move the market for high performance homes forward. I encourage all high performance home professionals to look to this AI Form 820.04 as a step in the right direction and a valuable tool to helping not only their businesses but our industry.
