Mortgage insurance, a commonly used credit enhancement, protects lenders against losses in the event of default, and FHA is a government mortgage insurer in a market that also includes private insurers. During fiscal years 2001 to 2003, FHA insured a total of about 3.7 million mortgages with a total value of about $425 billion. FHA plays a particularly large role in certain market segments, including low-income and first-time homebuyers. In 2000, almost 90 percent of FHA-insured home purchase mortgages had an LTV higher than 95 percent. FHA insures most of its mortgages for single-family housing under its Mutual Mortgage Insurance (MMI) Fund. To cover lender’s losses, FHA collects premiums from borrowers. These premiums, along with proceeds from the sale of foreclosed properties, pay for claims that FHA pays lenders as a result of foreclosures. In recent years, other members of the conventional mortgage market (such as private mortgage insurers, government-sponsored enterprises such as Fannie Mae and Freddie Mac, and large private lenders) have been increasingly active in supporting low and even no down payment mortgage products. For example, Fannie Mae and Freddie Mac’s no down payment mortgage products were introduced in 2000; and many private mortgage insurers will now insure a mortgage up to 100 percent LTV. However, the characteristics and standards for low and no down payment products vary among mortgage institutions. Currently, homebuyers with FHA-insured loans need to make a 3 percent contribution toward the purchase of the property and may finance some of the closing costs associated with the loan. As a result, an FHA-insured loan could equal nearly 100 percent of the property’s value or sales price. In recent years, a growing proportion of borrowers have received down payment assistance, which further helps them meet the hurdle of accumulating sufficient funds to purchase a home. Based on our preliminary analysis of FHA-insured loans that had LTVs above 95 percent, use of down payment assistance has grown to over half of such loans insured during the first seven months of 2005. When considering the risk of mortgages, a substantial amount of research GAO reviewed indicates that the LTV ratio and the borrower’s credit score are among the most important factors when estimating the risk level associated with individual mortgages. We also analyzed the performance, expressed by the percent of borrowers defaulting within four years of mortgage origination, of low and no down payment mortgages supported by FHA and others. Our analysis supports the findings we found in the research literature. Generally, mortgages with higher LTV ratios (smaller down payments) and lower credit scores are riskier than mortgages with lower LTV ratios and higher credit scores. As can be seen in Figure 1, when focusing only on LTV for FHA loans, default rates increase as the LTV ranges increase. In theory, LTV ratios are important because of the direct relationship that exists between the amount of equity borrowers have in their homes and the risk of default. The higher the LTV ratio, the less cash borrowers will have invested in their homes and the more likely it is that they may default on mortgage obligations, especially during times of economic hardship (e.g., unemployment, divorce, home price depreciation). Risk assessment is a very important component of issuing and insuring mortgages, particularly when introducing a mortgage product that has the risk associated with a higher LTV. To help assess the risks associated with mortgages, the mortgage industry has moved toward greater use of mortgage scoring and automated underwriting systems. Mortgage scoring is a technology-based tool that relies on the statistical analysis of millions of previously originated mortgage loans to determine how key attributes such as the borrower’s credit history, the property characteristics, and the terms of the mortgage note affect future loan performance. During the 1990s, private mortgage insurers, the GSEs, and larger financial institutions developed automated underwriting systems. Automated underwriting systems refer to the process of collecting and processing the data used in the underwriting process. These systems rely, in part, on individuals’ credit scores or credit history, and they have played an integral role in the provision of low and no down payment mortgage products. These systems allow lenders to quickly assess the riskiness of mortgages by simultaneously considering multiple factors including the credit score and credit history of borrowers. FHA has developed and recently implemented a mortgage scoring tool, called the FHA TOTAL Scorecard, to be used in conjunction with existing automated underwriting systems. More than 60 percent of all mortgages— conventional and government-insured—were underwritten by an automated underwriting system, as of 2002, and this percentage continues to rise. According to representatives of mortgage institutions we interviewed, they use a number of similar practices in designing and implementing new products. These practices can be especially important when designing and implementing new products with higher or less well understood risk, such as low and no down payment products. Some of these practices could be helpful to FHA in its design and implementation of a zero down payment product, as well as other new products. More specifically, mortgage institutions often establish additional requirements for new products such as additional credit enhancements or underwriting requirements. Although FHA has less flexibility in imposing additional credit enhancements it does have the authority to seek co-insurance, which it is not currently using. FHA makes adjustments to underwriting criteria and to its premiums, but told us that it is unlikely to use a credit score threshold for a new zero down payment product. Further, mortgage institutions also use different means to limit how widely they make available a new product, particularly during its early years. FHA does sometimes use practices for limiting a new product but usually does not pilot products on its own initiative. FHA officials with whom we spoke question the circumstances in which they can limit the availability of a program and told us they do not have the resources to manage programs with limited availability. Finally, according to officials of mortgage institutions, including FHA, they also often put in place more substantial monitoring and oversight mechanisms for their new products including lender oversight. In an earlier report, we made recommendations designed to improve HUD’s oversight of FHA lenders. Some mortgage institutions require additional credit enhancements— mechanisms for transferring risk from one party to another such as mortgage insurance—on low and no down payment products. Mortgage institutions such as Fannie Mae and Freddie Mac mitigate the risk of low and no down payment products by requiring additional credit enhancements such as higher mortgage insurance coverage. Fannie Mae and Freddie Mac believe that the higher-LTV loans represent a greater risk to them and they seek to partially mitigate this risk by requiring higher mortgage insurance coverage on these loans. For example, Fannie Mae and Freddie Mac require insurance coverage of 35 percent of the claim amount (on individual loans that foreclose) for loans that have an LTV of greater than 95 percent and require lower insurance coverage for loans with LTVs below 95 percent. Although FHA is required to provide up to 100 percent coverage of the loans it insures, FHA may engage in co-insurance of its single-family loans. Under co-insurance, FHA could require lenders to share in the risks of insuring mortgages by assuming some percentage of the losses on the loans that they originated (lenders would generally use private mortgage insurance for risk sharing). FHA has used co-insurance before, primarily in its multifamily programs, but does not currently use co-insurance at all. FHA officials told us they tried to put together a co-insurance agreement with Fannie Mae and Freddie Mac and, while they were able to come to agreement on the sharing of premiums, they could not reach agreement on the sharing of losses and it was never implemented. Mortgage institutions also can mitigate risk through stricter underwriting. For example, mortgage institutions such as Fannie Mae and Freddie Mac sometimes introduce stricter underwriting standards as part of the development of new low and no down payment products (or products about which they do not fully understand the risks). Institutions can do this in a number of ways, including requiring a higher credit score threshold for certain products, or requiring greater borrower reserves or more documentation of income or assets from the borrower. Once the mortgage institution has learned enough about the risks that were previously not understood, it can change the underwriting requirements for these new products. FHA could also benefit from mitigating risk such as through stricter underwriting. Although FHA has to meet some statutory standards, it retains some flexibility in how it implements a newly authorized product or changes an existing product. The HUD Secretary has latitude within statutory limitations in changing underwriting requirements for new and existing products and has done this many times. The requirements in H.R. 3043 that prospective zero down payment loans go through FHA’s TOTAL Scorecard and that borrowers receive prepurchase counseling are consistent with stricter underwriting. However, in addressing the final recommendations in our February report, FHA wrote that is unlikely to mandate a credit score threshold for a new zero down payment product because the new product is intended to serve borrowers who are underserved by the conventional market including those who lack credit scores. Also, FHA wrote that it is unlikely to mandate borrower reserve requirements since the purpose of a zero down payment product is to serve borrowers with little wealth or personal savings. Mortgage institutions can increase fees or charge higher premiums to help offset the potential costs of a program that is believed to have greater risk. For example, Fannie Mae officials stated that they would charge higher guarantee fees on low and no down payment loans if they were not able to require higher insurance coverage. FHA could set higher premiums in anticipation of higher claims from no down payment loans. Within statutory limits, the HUD Secretary has the authority to set up-front and annual premiums that are charged to borrowers who have FHA-insured loans. In fact, in the administration’s 2006 budget proposal for a zero down payment product, it included higher up front and annual premiums for these loans. Some mortgage institutions may limit in some way a new product before fully implementing the new product. For example, Fannie Mae and Freddie Mac sometimes use pilots, or limited offerings of new products, to build experience with a new product type or to learn about particular variables that can help them better understand the factors that contribute to risk for these products. Freddie Mac and Fannie Mae also sometimes set volume limits for the percentage of their business that could be low and no down payment lending. Fannie Mae and Freddie Mac officials provided numerous examples of products that they now offer as standard products but which began as part of underwriting experiments. These include the Fannie Mae Flexible 97® product, as well as the Freddie Mac 100 product. FHA has utilized pilots or demonstrations as well when making changes to its single-family mortgage insurance. Generally, HUD has done this in response to legislation that requires a pilot and not on its own initiative. For example, FHA’s Home Equity Conversion Mortgage (HECM) insurance program started as a pilot. Congress initiated HECM in 1987; the program is designed to provide elderly homeowners a financial vehicle to tap the equity in their homes without selling or moving from their homes (sometimes called a “reverse mortgage”). Through statute, HECM started as a demonstration program that authorized FHA to insure 2,500 reverse mortgages. Through subsequent legislation, FHA was authorized to insure an increasing number of these mortgages until Congress made the program permanent in 1998. Under the National Housing Act, the HECM program was required to undergo a series of evaluations and it has been evaluated four times since its inception. FHA officials told us that administering this demonstration for 2,500 loans was difficult because of the challenges of selecting a limited number of lenders and borrowers. FHA ultimately had to use a lottery to limit loans to lenders. H.R. 3043 also would mandate that FHA pilot the zero down payment program: it limits the annual number of zero down mortgages to 10 percent of the aggregate number of loans insured during the previous fiscal year, and sets an aggregate limit of 50,000 loans. The appropriate size for a pilot program depends on several factors. For example, the precise number of loans needed to detect a difference in performance between standard loans and loans of a new product type depends in part on how great the differences are in loan performance. If delinquencies early in the life of a mortgage were about 10 percent for FHA’s standard high LTV loans, and FHA wished to determine whether loans in the pilot had delinquency rates no more than 20 percent greater that the standard loans (delinquency no more than 12 percent), a sample size of about 1,000 loans would be sufficient to detect this difference with 95 percent confidence. If delinquency rates or FHA’s desired degree of precision were different, a different sample size would be appropriate. FHA officials told us they have conducted pilot programs when Congress has authorized them, but they questioned the circumstances under which pilot programs are needed. FHA officials also said that they lacked sufficient resources to appropriately manage a pilot. Additionally, some mortgage institutions may also limit the initial implementation of a new product by limiting the origination and servicing of the product to their better lenders and servicers. Mortgage institutions may also limit servicing on the loans to servicers with particular product expertise, regardless of who originates the loans. Fannie Mae and Freddie Mac both reported that these were important steps in introducing a new product and noted that lenders tend to take a more conservative approach when first implementing a new product. FHA officials agreed that they could, under certain circumstances, envision piloting or limiting the ways in which a new or changed product would be available but pointed to the practical limitations in doing so. FHA approves the sellers and services that are authorized to support FHA’s single-family product, but FHA officials told us they face challenges in offering any of their programs only in certain regions of the country or in limiting programs to certain approved lenders or servicers. FHA generally offers products on a national basis and, when they do not, specific regions of the county or lenders might question why they are not able to receive the same benefit (even on a demonstration or pilot basis). However, these officials did provide examples in which their products had been initially limited to particular regions of the country or to particular lenders, including the rollout of the HECMs and their TOTAL Scorecard. Mortgage institutions, including FHA, may take several steps related to increased monitoring of new products and subsequently make changes based on what they learned. Fannie Mae and Freddie Mac officials described processes in which they monitor actual versus expected loan performance for new products, sometimes including enhanced monitoring of early loan performance. Some mortgage institutions, such as Fannie Mae, told us that they may conduct rigorous quality control sampling of new acquisitions, early payment defaults, and nonperforming loans. Depending on the scale of a new initiative, and its perceived risk, these quality control reviews could include a review of up to 100 percent of the loans that are part of the new product. FHA officials told us they also monitor more closely loans underwritten under revised guidelines. Specifically, FHA officials told us that FHA routinely conducts a review of underwriting for approximately 6 to 7 percent of loans it insures. According to FHA officials, as part of the review, it may place greater emphasis on reviewing those aspects of the insurance product that are the subject of a recent change. Fannie Mae and Freddie Mac also reported that they conduct more regular reviews at mortgage servicer sites for new products. In some cases, Fannie Mae and Freddie Mac have staff who conduct on-site audits at the sellers and servicers to provide an extra layer of oversight. According to FHA officials, they have staff that conduct reviews of lenders that they have identified as representing higher risk to FHA programs. However, we recently reported that HUD’s oversight of lenders could be improved and identified a number of recommendations for improving this oversight. Loans with low or no down payments carry greater risk. Without any compensating measures such as offsetting credit enhancements and increased risk monitoring and oversight of lenders, introducing a new FHA no down payment product would expose FHA to greater credit risk. The administration’s proposal for a zero down product included increased premiums to help compensate for an increase in the cost of the FHA program which would permit FHA to potentially offset additional costs stemming from a new product that entails greater risk or not well understood risk. The proposed bill also requires that borrowers receive prepurchase counseling. Although FHA appears to follow many key practices used by mortgage institutions in designing and implementing new products, several practices not currently or consistently followed by FHA stand out as appropriate means to manage the risks associated with introducing new products or significantly changing existing products. Moreover, these practices can be viewed as part of a formal framework used by some mortgage institutions for managing the risks associated with new or changed products. The framework includes techniques such as limiting the availability of a new product until it is better understood and establishing stricter underwriting standards—all of which would help FHA to manage risk associated with any new product it may introduce. For example, FHA could set volume limits or limit the initial number of participating lenders in the product. Further, changes in FHA’s premiums, an important element of the administration’s 2006 budget proposal for a zero down payment product would permit FHA to potentially offset additional costs stemming from a new product that entails greater risk or not well understood risk. However, FHA officials believe that the agency does not have sufficient resources to implement products with limited volumes, such as through a pilot program. Yet, when FHA makes new products widely available or makes significant changes to existing products with less-understood risks, these products or actions also can introduce significant risks. Products that would introduce significant risks can impose significant costs. We believe that FHA could mitigate these risks and potential costs by using techniques such as piloting. Moreover, FHA told us that it believes that pilot programs are not needed because the risks of every new year of loans are assessed annually as part of credit subsidy budgetary transactions and in its annual actuarial study, and it could terminate the program early in its life if it identified problems. However, because it may take a few years to determine the risks of a new loan product, early termination could still expose the government to significant financial risk without some type of limits on the number of loans insured. If FHA is unsure about its authority to conduct pilots or concerned about expectations of equitable distribution of its products, Congress can make clear that FHA has this authority by requiring a product to be implemented as part of a pilot, or by explicitly giving the HUD Secretary the authority to establish and implement pilots for new products. If Congress authorizes FHA to insure a no down payment product or any other new single-family insurance products, Congress may want to provide guidance and clear authority to FHA on this new product. Congress may want to consider a number of means to mitigate the additional risks that these loans may pose. Such means may include limiting the initial availability of such a new product, requiring higher premiums, requiring stricter underwriting standards, or requiring enhanced monitoring. Such risk mitigation techniques would serve to help protect the Mutual Mortgage Insurance Fund while allowing FHA the time to learn more about the performance of loans using this new product. Limits on the initial availability of the new product would be consistent with the approach Congress took in implementing the HECM program. The limits could also come in the form of an FHA requirement to limit the new product to better performing lenders and servicers as part of a demonstration program or to limit the time period during which the product is first offered.

Summary: To assist Congress in considering legislation to authorize the Secretary of the Department of Housing and Urban Development (HUD) to carry out a pilot program to insure zero down payment mortgages, this testimony provides information about practices mortgage institutions use in designing and implementing low and no down payment products. It also contains information about how these practices could be instructive for FHA in managing risks associated with a zero down payment product--a product for which the risks are not well understood. This testimony is primarily based on GAO's February 2005 report, Mortgage Financing: Actions Needed to Help FHA Manage Risks from New Mortgage Loan Products, (GAO-05-194). In recent years, many mortgage institutions have become increasingly active in supporting low and even no down payment mortgage products. In considering the risks of these new products, a substantial amount of research GAO reviewed indicates that loan-to-value (LTV) ratio and credit score are among the most important factors when estimating the risk level associated with individual mortgages. GAO's analysis of the performance of low and no down payment mortgages supported by FHA and others corroborates key findings in the literature. Generally, mortgages with higher LTV ratios (smaller down payments) and lower credit scores are riskier than mortgages with lower LTV ratios and higher credit scores. Some practices of other mortgage institutions offer a framework that could help FHA manage the risks associated with introducing new products or making significant changes to existing products. Mortgage institutions sometimes require additional credit enhancements, such as higher insurance coverage, and stricter underwriting, such as credit score thresholds, when introducing a new low or no down payment product. FHA is authorized to require an additional credit enhancement, but does not currently use this authority. FHA has used stricter underwriting criteria, but told us it is unlikely they would use a credit score threshold for a new zero down payment product. Mortgage institutions may also impose limits on the volume of the new products they will permit and on who can sell and service these products. FHA officials question the circumstances in which they can limit volumes for their products and believe they do not have sufficient resources to manage a product with limited volumes, but the potential costs of making widely available a product with risk that is not well understood could exceed the cost of initially implementing such a product on a limited basis.
