What Percentage of Homes in the US are Owned Free and Clear: Mortgage Paid Off!
Considering that today 90% of all homeowners have more than 20% equity based on their initial loan, it is highly unlikely that there will be a housing crash or bubble similar to 2008. The housing market in the US is very strong with over 37% of people in the 2020 census owning their home free and clear without a mortgage payment because it is paid off.
The census did not specify the percentages of home owners living in the home vs rental properties.
