PACE Financing: What Appraisers Should Know

By Michael V. Sanders, MAI, SRA

PACE, an acronym for Property Assessed Clean Energy, is a relatively new and somewhat innovative financing mechanism for energy efficiency, renewable energy and water conservation projects (think insulation, replacement windows and photo-voltaic solar systems as typical examples). While PACE is effectively a loan, it is repaid as an assessment on an owner’s property tax bill, and is available for both residential and commercial/industrial properties in selected areas of the country. So what does this have to do with appraising?

PACE assessments can be substantial depending on the improvements funded. And because they are paid as a tax assessment that runs with the property over a specified term, they have priority over normal financing. Existing PACE loans have reportedly been an issue in many transactions, due to both buyer resistance and reluctance of lenders to finance the sale and potentially jeopardize their loan security to a superior lien. In some cases, sellers have been required to pay off a PACE loan before closing, significantly reducing their net proceeds. Thus it is clear that PACE assessments can and do impact property value.

The PACE program effectively started in 2009. PACE-enabling legislation has currently been passed in 33 states, authorizing local governments to establish PACE programs for both residential and commercial properties. While residential PACE programs presently operate in only three states – California, Florida and Missouri – widespread government support for energy efficiency and renewable energy improvements makes it likely that use of this financing mechanism will increase in the future.

A major issue with PACE financing is its status as a “super lien.” Since PACE is a tax assessment, it technically has priority over new or existing loans, which has generated significant resistance from regulatory agencies and the secondary market. FNMA and FHLMC have refused to back mortgages on properties with PACE loans, noting the most recent FNMA Selling Guide in May 2017 stating that the agency “will not purchase mortgage loans secured by properties with an outstanding PACE loan unless the terms of the PACE loan program do not provide for lien priority over first mortgage liens.” Cash-out refinancing is permitted to pay off an existing PACE loan as part of the refinance, however.

FHA and VA guidelines in mid-2016 seek to maintain their first lien position by classifying a PACE loan as a tax assessment and not a super lien, although several prominent housing industry trade groups are unconvinced, characterizing the guidance as “form over substance.”

Notwithstanding problems in the lending markets, the cumulative dollar volume of residential PACE loans, which was relatively small prior to 2014, has since skyrocketed, exceeding $3.8 billion in June 2017. The chart below from PACENation ( shows the exponential growth of residential PACE financing in the residential sector from late 2009 to date.

Access Denied
Today’s lenders have access to massive amounts of data. According to Hagar, government lenders have access to every recorded sale in most every county across the U.S. via information providers like CoreLogic. He believes appraisal adjustments should be cross-checked against sales metrics of the five million home sales that occur each year.

However, appraisers typically use Multiple Listing Service (MLS) for residential appraising. Data provided by MLS may vary from information shown by providers like CoreLogic. MLS has more detailed information that county records don’t contain. Oftentimes, though, MLS contains errors or missing data. In other words, both types of systems have errors, but not necessarily the same errors.

Increasingly, appraisers indicate that underwriters are rejecting appraisal reports for vague reasons based on ambiguous results from CU analysis. Problems arise when these methods are not accessible or replicable for others to validate results. Mr. Hagar emailed us his opinion:

Many appraisers do not understand how the CU system works. When there is a lack of understanding, people tend to reject the results and fight back.  When the CU system spits out, “Your adjustments are different from what the model indicates or other appraisers in your area are using,” many appraisers don’t understand how the lender or CU arrived at this conclusion. What algorithm was used? What data were analyzed? All are legitimate questions that usually go unanswered.

By design, the CU output is only provided to the lender. The person reading the output is not supposed to simply cut and paste the comments into an email and send them to the appraiser. Unfortunately, many poorly trained people working for lenders and appraisal management companies do just that – cut and paste – without telling the appraiser, “Data indicates something different than what you indicated; how did you [the appraiser] determine the adjustment for x?” The CU isn’t necessarily telling the appraiser they are wrong; it is merely stating that their adjustments are different and therefore questionable.

Many appraisers fail to understand that they do indeed have access to the same sales data that the CU uses. Sales are sales, regardless of the storage method. The CU analyzes the sales data using their secret algorithm. Appraisers can use the same data along with a different method and produce a similar or different conclusion. For this reason, appraisers cannot guess at what an adjustment should be; they must have a valid method to determine the adjustment or their conclusions will be tested and questioned.

This brings us back to where we started; data must be properly analyzed using an acceptable, repeatable methodology. Otherwise, results are merely a guess.

Transparency & Reproducibility
Transparency and reproducibility are key ingredients of good science and, we would argue, of appraising also. It requires that data and methods, including computer code, be made available. Whatever the information vessel – in science, appraisals, or otherwise – these elements are imperative to validate methods. Denying access to the methods used to form an opinion becomes a serious issue, such as with CU, when the results are viewed as “true.” Neither science nor appraising can be replicated on its own; people need the data to recreate the studies. They need the model to verify the methods.

This is from (Shuttleworth, M. Reproducibility. 14 June, 2009): “Reproducibility is regarded as one of the foundations of the entire scientific method, a benchmark upon which the reliability of an experiment can be tested. The basic principle is that, for any research program, an independent researcher should be able to replicate the experiment, under the same conditions, and achieve the same results.”

On the surface, CU guidelines align with these principles by promising, “Appraisers that make a good faith effort to use the most similar comparables, provide accurate and consistent data, and support their adjustments with market data and analysis can generally expect a minimum of CU feedback that would cause a follow-up request from the reviewer.” However, word on the street from appraisers shows quite the opposite. As mentioned previously, lenders are sending feedback such as:

  • Do you have data to support this adjustment?
    • We are asking that you take a class on how to support and prove your adjustments.
    • The appraiser’s net adjustments for the comparable sales are materially different from the model net adjustments.
    • The appraiser-provided comparables are materially different than the model-selected comparables.

How is the appraiser to understand feedback like this and understand the models when they aren’t made available? The process doesn’t lend itself to either transparency or reproducibility.

Fannie Mae emphasizes, “An accurate description of the physical condition and quality of the subject property is a critical element in arriving at a supportable opinion of market value, as well as in the prudent underwriting of a mortgage loan.” Lenders initially rely on appraisals to give an accurate firsthand description of the subject since the appraisers are, after all, on the front lines of evaluating properties. However, lenders later rely on CU feedback to tell them whether or not the appraiser’s eyewitness assessment is correct.

Collateral Underwriting
According to CU guidelines outlined by Fannie Mae, specific factors contribute to successful CU implementation. Among these are considering the restrictions of automated analysis, awareness of possible property or neighborhood nuances, and ensuring educated appraiser opinions are a priority over computerized results.

Fannie Mae’s guidelines expect lenders to “use human due diligence in combination with the CU findings.” They go on, “Lenders should not, however, make demands or provide instructions to the appraiser based solely on automated feedback.” However, this appears to be what is happening. Appraisers are accountable for conclusions driven by unknown models and an obscure algorithm for selecting sales to analyze. Their common-sense opinions are being overridden by the all-knowing system.

CU legalities forbid providing appraisers access to the CU interface or reports containing CU findings. Yet Fannie Mae claims, “CU is model-based and performs a more comprehensive analysis of data integrity, comparable selection, adjustments, and reconciliation.” If this were the case, according to basic scientific principles, then outside parties (appraisers) would be allowed access in order to verify the data and analysis.

In short, residential appraisers may be unfairly criticized and condemned for their conclusions and have no method for rebuttal. Potential discrepancies are issued based upon this model without the appraiser being fully informed of the basis for criticism; the appraiser has no opportunity to examine the questionable sales and explain why adjustments were made. No clarification is offered regarding why the appraiser’s opinions are contested. The process caters to underwriters, often leaving appraisers frustrated and unable to defend their work.

Shine the Light
Once again, CU models may be perfectly good- or they may not be. We have no way of knowing since Fannie Mae won’t share them. This leaves ambiguity whether appraisers are being treated fairly.

We must ask ourselves:

  • Is the CU tool a one-size-fits-all method?
    • If so, is the implementation in keeping with its own design of, “Well-informed human judgement should take precedence over automated results”?
    • More importantly, do CU methods align with the basic principles of good science?

Until the models are made available we don’t have answers. A disconnect exists between Fannie Mae guidelines, lender interpretations and feedback to the appraiser. Meanwhile, appraisers must continue responding to lender requests and defending their conclusions as thoroughly as possible with the limited tools available to them.

  1. Interesting that not one method or technique noted in the article measures actual participants reactions. I’m a pretty ‘typical’ buyer in terms of my requirements for a property title. I am NOT going to pay the seller more for a special feature that I in turn have to then pay off myself! IF the loan was used for (owned vs leased) solar panels; insulation and or windows that’s fine provided (1) ALL the added cost is recognized as market value BY the market and (2) the seller PAYS OFF THE LIEN!

    I dont mean this to be a Catch-22 issue but if the items the lien is for don’t add as much or more than the lien pay off to the value, then they are a functional inadequacy. I’m not paying extra for functional inadequacy or super-adequacy as the case may be. I’m also not going to pay $25k to $50k more for a property via down payment or financing and then turn around and pay more in taxes for the same items that provided a higher price to the seller!

  2. Due to the inherent problems with this program,ie. unscrupulous contractors, high interest rates, super liens, ect. the County of Kern, California and the City of Bakersfield, California has recently voted to not allow these products and loans to operate. More people than not had been taken or did not realize what they were getting into. As you suggested, it was always difficult to value and the owners had a very difficult time selling.
