* The median rental price underlying this estimate was affected by the same pandemic-induced survey issues influencing the homeownership and vacancy rates for Q2 2020 through Q2 2021 (see Homeownership and Housing Vacancy section). Normal data collection procedures resumed in Q3 2021. The rental price will be reviewed with the availability of new Census ACS data, although the ACS survey methods were also affected by COVID-19 restrictions.

** The share of previous-quarter shipments sold (or leased) and placed for residential use four months after shipment. For shipments in the first quarter, for example: sales and placements (from January - May) for January shipments; (from February - June) for February shipments; and (from March - July) for March shipments are summed and divided by the total number of homes shipped in the first quarter to obtain the percentage of manufactured homes sold and placed four months after shipment.

*** Commitment (advertised) rates on the 5-Yr ARM are now reported in place of rates on the 1-Yr ARM. Freddie Mac discontinued surveying lenders on the 1-Yr ARM as of January 2016.

**** FHA market share estimates are based on new methodology beginning with the Q3 2013 report; estimates were revised back through Q1 2011. See the FHA Market Share report on their website for an explanation of the new methodology: https://www.hud.gov/program_offices/housing/rmra/oe/rpts/fhamktsh/fhamktqtrly.

***** FHA mortgage applications and endorsements data have been revised to exclude Home Equity Conversion Mortgages (HECM) beginning with the Q3 2013 release.

****** The Q2 2020 - Q2 2021 data on homeownership and vacancy rates, housing stock, and households should be viewed with caution. The data are based on the BLS Current Population Survey/Housing Vacancy Survey conducted by the Census Bureau and represent a break in the series because the surveys were conducted under COVID-19 restrictions that prevented normal data collection procedures. In-person interviews were suspended on March 20, 2020, and the Q2 survey was conducted solely by telephone interviews. In-person interviews were incrementally added back for the surveys from Q3 2020 through Q2 2021 with respective rates of 63, 94, 98, and 99 percent of the in-person interviews allowed. Normal data collection procedures resumed in Q3 2021. See Source and Accuracy release https://www.census.gov/housing/hvs/index.html.
