US Mortgage Lock-in Effect Drives Rise of 'Accidental Landlords'

Homeowners in the United States are increasingly becoming 'accidental landlords' due to the mortgage lock-in effect, where low existing interest rates deter them from selling and moving.

A growing number of American homeowners are turning into 'accidental landlords' as the mortgage lock-in effect significantly influences their housing decisions. This phenomenon occurs when individuals possess mortgages with substantially lower interest rates than those currently available on the market.

Faced with the prospect of selling their existing property and then securing new financing at higher rates, many homeowners who need to relocate for reasons such as work or family choose to rent out their current homes instead. This strategic decision allows them to retain their favourable mortgage terms while still addressing their need for a new residence, effectively transforming them into landlords by circumstance rather than initial intent. This trend also contributes to a reduced supply of homes for sale in the US market.
