OWNING A HOME EVALUATION STUDY
(OMB CONTROL NUMBER: 3170-XXXX)
Describe (including a numerical estimate) the potential respondent universe and any
sampling or other respondent selection method to be used. Data on the number of entities
(e.g., establishments, State and local government units, households, or persons) in the
universe covered by the collection and in the corresponding sample are to be provided in
tabular form for the universe as a whole and for each of the strata in the proposed sample.
Indicate expected response rates for the collection as a whole. If the collection has been
conducted previously, include the actual response rate achieved during the last collection.
The target audience for the Owning a Home suite of tools is prospective homebuyers. To
replicate this target audience as much as possible, the respondent universe is composed of
qualified users of a national home buying website. Qualified users are defined as those who
have registered accounts and who have both opted-in to receive marketing emails and have saved
criteria for a home search on their website profile. A random sample of qualified users will be
invited to participate in the study via email and directed to visit the study’s homepage. The
partner website will send these recruiting emails using their email management system. We will
use phased recruitment waves to target an initial pool of approximately 230,000 potential
respondents who receive the email and click through to the study homepage. We may adjust this
target up or down based on early results from the initial recruitment waves.
We acknowledge that qualified users may be different from the general population of prospective
homebuyers, especially insofar as they are likely to be especially comfortable with online tools
and resources. However, in order to recruit consumers who are actively shopping for a home, we
need access to a large number of people who can easily be identified as prospective homebuyers.
We do not intend to extrapolate our findings to larger populations, including a general population
of internet users or homebuyers. Nevertheless, based on results from our pilot study, we expect
that the final sample will be diverse in terms of age (25-29 to over 65) and credit scores (less
than 580 to over 760). Respondents from our pilot study varied in terms of marital status (62.6%
married), education (5% high school graduates, 28% with an associate’s degree or some college,
39% college graduates, and 29% with postgraduate studies), gender (% male), yearly income
(8% less than $35,000, 6% between $35,000 and $49,999, 23% between $50,000 and $74,999,
20% between $75,000 and $99,999, 24% between $100,000 and $174,999, and 19% with
$175,000 or more), and other characteristics.
Potential respondents will be asked to complete a short screening questionnaire to determine
eligibility for the study. To be eligible, a respondent must intend to purchase a home in the next
3 months, intend to pay for that purchase using a mortgage, be involved in financial decisions in
his/her household, and not be professionally involved in the real estate industry.
Based on pilot experience, we anticipate that approximately 74% of the potential respondents
who arrive at the study home page will complete the screener, of which about 25% will be found
eligible. Of those eligible respondents, we anticipate about 59% will agree to participate in the
study, for an overall study pool of approximately 25,000 and a participation rate of 11% of the
recruited pool.

As this is a longitudinal study occurring over three months, there is likely to be considerable
attrition over time. Based on pilot experience, we estimate that approximately 4,122 participants
will complete the entire study, amounting to approximately 16% of the participants who opted in
and approximately 1.8% of the overall recruited pool. Monetary incentives will be offered to
encourage participation in the study and to incentivize survey completion. Further efforts to
increase response rates are detailed below.
1. Describe the procedures for the collection of information:
Data will consist of a combination of participant surveys, administrative data from the Owning a
Home suite of tools, and data from participants’ mortgage documents. Before analysis, data will
be de-identified to exclude any direct identifying information protect the privacy of sampled
consumers.
Participant surveys: Surveys will be used to obtain additional information on
respondents’ shopping behavior, perceptions of the mortgage market, expectations of
personal mortgage terms, mortgage knowledge, and feelings of empowerment. Surveys
will be administered online every two weeks for three months or until a home is
purchased, whichever occurs first. An initial baseline survey will additionally contain
information on respondents’ background characteristics, including an overview of their
existing assets and liabilities. Closing surveys will ask for information on the
respondent’s experiences at closing, the terms of their home purchase and the mortgage
that they obtained, including a request to provide the final mortgage documents. If
participants have not purchased a home before the end of the three month study window,
they will be asked to complete a final closing survey, administered upon closing and up
to 8 weeks later.
Owning a Home web suite of tools: Website metrics will include measures of
participants’ activity on the site. For instance, participants may access various tools (e.g.
background information on the process of searching for a mortgage, a mortgage rate
benchmarking tool, or a guide to loan options), and may spend varying amounts of times
on each. To ensure participants’ privacy and eliminate re-identification risk, the CFPB
will provide web analytics data to the study contractor using a set of unique participant
ID codes provided by the contractor through the referral links. The contractor will match
the web analytics data with the rest of the study data using this ID code. The contractor
will then assign a new, different, and randomized unique ID code to each record after
matching the data. The CFPB will receive only this second identifier in the final deidentified analysis dataset.
Mortgage document data: Mortgage data will be provided either through direct access
to mortgage documents or by respondents answering survey questions about their
mortgage terms, whichever method participants prefer. Specifically, respondents who
provide their documents directly have the option to upload an electronic document
(including taking a picture of the forms) or faxing the information. Those who choose to
answer survey questions will be asked basic mortgage information, such as the amount of
the loan and the interest rate. Survey questions will be administered during standard
survey procedures.
a. Include statistical methodology for stratification and sample selection,
As described above, the sample will be drawn from a home-buying website’s existing registered
users. Potential respondents will be asked to complete a short screening questionnaire first in
order to determine if they are eligible. Data obtained in the screening questionnaire does not
contain any directly identifying information and will be analyzed only to assess eligibility. Upon
completing the screening questionnaire, respondents are presented with informed consent
language and asked to opt-in to the study.
The research team does not anticipate the need to rely on stratification, although respondents
may be analyzed according to individual characteristics (e.g. previous homeownership
experience). Findings from this study will not be generalized to larger populations, including
internet users, all homebuyers, or the U.S. population.
b. Estimation procedure,
The primary analytic technique for estimating the impact of a randomized controlled trial (RCT)
such as this study is a comparison of outcomes for participants in different study groups. In this
study, the research team will compare outcomes for participants who were given access to the
Owning a Home tools (the first treatment group) to outcomes for participants who were
encouraged to shop for their mortgage (the second treatment group) and to those who did not
receive any additional resources (the control group). The research team intends to use “intent to
treat” analysis, thereby estimating effects on those who had the opportunity to receive treatment,
including those who did and did not use the tools. This analysis will identify the causal impact
of the treatments on mortgage outcomes for those in the study population.
Estimates of the differences between the two groups will be calculated using data from surveys,
usage of the Owning a Home website, and mortgage outcomes. For each difference, statistical
confidence intervals will be calculated using standard statistical assumptions.
For some outcomes, the research team is additionally interested in how outcomes changed during
the home shopping process. For example, it may be expected that respondents who have
completed their home purchase and have closed on a mortgage will have higher knowledge of
the mortgage process than those who are in the initial stages of their home search. As such,
changes in mortgage knowledge between baseline and the final survey will be compared for
those in treatment and control groups.
c. Degree of accuracy needed for the purpose described in the justification,
There is limited existing data on the methods that prospective homebuyers use to search for
home and mortgage options. Additionally, there is limited evidence regarding how much money
homebuyers save from obtaining an additional mortgage estimate. As such, it is difficult to
estimate the expected effects of the described intervention, and in turn, the degree of accuracy
required.
Based on power analyses using existing information on estimated savings from mortgage search,
the research team has estimated that approximately 3,300 participants are needed to complete the
study in order to detect a difference between those exposed to the Owning a Home tools, those
who receive the shopping treatment, and those who receive neither. Given uncertainty around
the level of attrition in the later stages of the study, the recruitment plan is sufficient to produce
3,300 complete participants with some additional buffer.
d. Unusual problems requiring specialized sampling procedures, and
The research team does not anticipate using any specialized sampling procedures.
e. Any use of periodic (less frequent than annual) data collection cycles to reduce
burden.
The proposed research is a one-time collection (i.e., it will not be repeated annually), however
the collection is accomplished using several discrete surveys. Respondents will be asked to
report information every two weeks, for a period of approximately three months. This frequency
of survey was chosen so as to ensure that we can capture the changes in consumers’ attitudes and
behaviors over a relatively short mortgage shopping/acquisition window. To minimize burden,
the individual surveys will be kept short.
2. Describe methods to maximize response rates and to deal with issues of non-response.
The accuracy and reliability of information collected must be shown to be adequate for
intended uses. For collections based on sampling a special justification must be
provided for any collection that will not yield “reliable” data that can be generalized to
the universe studied.
Non-response may be a challenge for this study, particularly because respondents are being
asked to participate multiple times throughout their shopping process. While we will strive to
minimize attrition over the course of the study, we will also include data from participants who
partially participated where appropriate. The survey modules have been carefully designed to
collect the data needed for analysis while minimizing burden to participants. Additionally, a
combination of strategies is being employed to address non-response, as outlined below.
Strategies to maximize participation
a. Participants will be offered a monetary incentive, which has been shown to increase
response rates. 1
b. Reminder emails will be sent to those who have not taken a survey or who dropped
out in the middle. These emails will request that participants complete the survey.
Such reminders have been shown to increase response rates. 2

60(6): 821-36.
a. To reduce respondent burden, the survey has been constructed so that participants
will answer only a subset of questions for each survey. Specifically, the survey
modules that are administered will change depending on a small set of initial
questions that allow us to quickly assess the respondent’s current situation. By
reducing the number of questions that are asked (and the associated time required to
respond) more respondents are expected to complete the surveys.
b. Additionally, participants will be allowed to “suspend” their survey session so that
they can “resume” it at a later date. Such a design accommodates technical problems
that may prohibit participants from completing the survey, such as an Internet
connection issue, as well as scheduling constraints. 3
3. Describe any tests of procedures or methods to be undertaken.
In preparing for this study, the CFPB has tested the survey instrument using cognitive interviews
and tested the data collection procedures in a pilot study.
The CFPB conducted two sets of cognitive interviews in order to refine the survey instrument. 4
The first set of interviews was conducted on September 25 and 26, 2014 while the second set
was conducted from March 6, 2015 through March 10, 2015. During both sets of interviews,
participants were asked open-ended questions regarding their understanding of study materials,
revealing problems with question comprehensibility and response options. Study materials were
subsequently refined to address these issues.
The pilot study was conducted from October 27, 2014 through November 9, 2014. This study
was conducted using procedures that were designed to parallel those from the full study and was
intended to assess only methodological issues. Specifically, participants were recruited through
an email solicitation, answered screening questions, and completed the baseline survey and up to
two periodic surveys. No participants closed on a home during this pilot, and therefore we did
not receive any data surrounding mortgage outcomes or changes in mortgage
knowledge/empowerment from baseline to closing.
We assessed the pilot study data for item-level non-response and participant attrition, concluding
that we should try to reduce respondent burden as much as possible. As such, the CFPB revised
the survey instrument and implementation method. An example of each change is as follows:
•

Survey instrument: Questions with low variance were eliminated in order to reduce the
length of the survey instrument. For example, 83.0% of respondents in the pilot study
could correctly identify the concept of “home equity”; therefore, we no longer ask this

question. Eliminating questions reduces the length of the survey instrument and
corresponding respondent burden.
Implementation method: The survey invitation now contains unique links so that
participants do not have to enter a survey password. This change reduces respondent
burden and is expected to reduce attrition.

of the design and the name of the agency unit, contractor(s), grantee(s), or other
person(s) who will actually collect and/or analyze the information for the agency.
