Lemmings continue to vastly underestimate who landlords are.

In fact, fewer than one-fifth of rental properties are owned by for-profit businesses of any kind. Most rental properties – about seven-in-ten – are owned by individuals, who typically own just one or two properties, according to 2018 census data. And landlords have complained about being unable to meet their obligations, such as mortgage payments, property taxes and repair bills, because of a falloff in rent payments.

Individual investors owned nearly 14.3 million of those properties (71.6%), comprising almost 19.9 million units (41.2%). For-profit businesses of various sorts owned 3.7 million properties, or 18.8%, but their holdings totaled 21.7 million units, or 45% of the total. Entities such as housing cooperative organizations and nonprofits owned smaller shares of the total.

only about half of individual landlords reported net income in 2018, with the rest losing money on their properties. Such losses can, under certain conditions, be used to offset other taxable income.
