The single-family agency MBS market benefits from a set of consistent standards that allows traders and analysts to make straightforward judgments about relative value between securities. This is particularly the case for the conforming mortgage market since the single security UMBS market was launched in June 2019. The result is a market that is very liquid, supporting homeownership and affordability.

There is a very different situation in the multifamily space. The programs are very distinct across, and even within Agencies. This is particularly the case for the Ginnie Mae program, which consists of construction loans that are lines of credit that are drawn upon, and then converted to project loans. The two largest programs within the GSE multifamily space are the Fannie Mae DUS program[1], where losses are shared between Fannie Mae and the underwriting banks, and the Freddie K-deals, where losses are shared with investors[2]. Both Agencies have numerous smaller programs as well with their own distinct characteristics.

In the single-family space, the unit of analysis is the mortgage. These are pooled, and pools and loans are sometimes, in turn, aggregated into CMOs (We classify highly-structured deals such as Freddie K, Q, ML, SB, etc., as CMOs, too). Investors have a complete picture of activity in this market. In the multifamily space, however, the picture is murkier. There are two reasons for this. First is the multitude of different programs across the Agencies as cited above. The second is that a consistent data set for multifamily loans across the three agencies is not easily produced, as loans are typically securitized into pools, however, Freddie tends to securitize loans directly into structures more like CMOs, such as Freddie K, Q, SBL programs[3]. A year ago, we posted a note that described our bottom-up approach to sizing the multifamily market and validated this by comparing our calculation to similar figures obtained from the Federal Reserve Z.1 report. We are pleased to report that this approach continues to provide an accurate picture of total market size as our figures for the third quarter have consistently aligned within a margin of 0.5% for the past three years.

Some months ago, we set off to assess the impact of high interest rates on the usage of appraisal waivers. It soon became clear that we first needed to look in some detail at recent developments in the structure of the new market for appraisal modernization[1]. In this piece, we return to the original question.

To begin we look at the landscape of loan deliveries for Freddie Mac and Fannie Mae across the suite of available approaches towards appraising property values. Below find such charts for purchase mortgages.

On June 29, 2023, both Fannie Mae and Freddie Mac announced enhancements to their MBS disclosures starting with the September monthly release[1]. The data covers active pools issued back to January 2022. As rates were quite low prior to this time, these disclosures cover the relevant period of high demand for buydowns:

In a recent post, we discussed trends in commercial real estate outstanding debt, with an emphasis on the Agency multifamily market[1]. We mentioned that the key difference between risk sources associated with multi- and single-family debt is that the I/O structure and balloon term that predominates in multifamily loans implies that there is significant refinance risk in this market.
​
We also previously wrote that we have collected all the loans in the major Agency multifamily books and verified that this data was consistent with the Federal Reserve’s Z.1 report[2]. We are now prepared to take some first steps at estimating the extent of this risk. To simplify things, in this note, we look just at the two major GSE multifamily programs, Freddie Mae DUS[3] and Freddie Mac K-deals[4].

To begin, as of August 1, 2023, the Fannie Mae DUS deals account for $384.5 bn or 86% of the total FNM book of $448.1 bn, while Freddie K deals account for $317.9 bn or 83% of $384.9 bn outstanding as of June 1, 2023. Superficially similar.
​
Below find the maturities for the two programs by year starting in June 2023 for Freddie Mac and August 2023 for Fannie Mae[5]:

On September 15, Recursion Data was cited in a story in Commercial Mortgage Alert that pointed out that Fannie Mae “has started to restrict the interest-only payment periods on debt backing properties built before 2000.” They cite Recursion data in pointing out that Fannie Mae purchased $4.2 bn in multifamily loans in August, bringing the year-to-date total to 35.3 billion, down 20% from the same period in 2022.
​
Recursion is pleased to provide excellent support to all participants in this crucial segment of the commercial real estate market.

We’ve written many, many times about the inexorable rise in the role of nonbanks in the mortgage market[1]. A variety of factors have contributed to these gains, including superior technology, a relatively less oppressive regulatory environment, and Covid-19 chasing people out of bank branches online. 
​
This picture can be a little blurry, however, depending on the way you look at the market. There is, for example, the distinction between servicing book shares and origination shares. Our agency disclosure data doesn’t provide information on originators, but we can use “seller” as a proxy. The table below looks at the trends in outstanding portfolio and issuance for the conforming and Government markets over the period January 2022 – July 2023:

Overview
The release of the Financial Accounts of the United States (also known as the Z.1[1]) is always an opportunity to learn about important structural changes in the mortgage market. This is particularly the case in our current environment of high home prices and borrowing costs which we call “mortgage winter”. In this note, we focus on the breakdown on the ownership of risk for single family mortgages. This is not the share of ownership of MBS; it is who bears the credit risk for the loans.

Unsurprisingly, the growth in single-family mortgage credit outstanding in Q1 grew by the smallest amount in almost 7 years in the first quarter of 2023:

The last time we discussed the topic of appraisal waivers was at the end of 2022, when we looked at the impact of sharply higher interest rates on the use of this flexibility. Property valuation impact profitability of loan origination. Lenders can gain a significant advantage if they fully understand and choose from all the options in front of them. Given recent market developments, it is no doubt time to take another look at this topic, but structural change has come to this space, so it makes sense to discuss this first.

​Until last year we were in a binary appraisal/waiver world. One or zero. For some time, there have been discussions of various “modernization” programs somewhere in between, with valuations produced via a process that requires less information than that obtained from a full appraisal but not no information.
