The “Lock-In Effect”: Why Some Homeowners Stay Put

By David Parks · eXp Realty · The Apollo Group · 2 min read

The Short Answer

The lock-in effect is when homeowners with low mortgage rates choose not to sell because a new loan would cost more each month. It can reduce the number of homes for sale.

How it works

Someone with a low fixed rate has a strong reason to stay, even if they want a different home. Selling means giving up that rate and taking a new one at current levels.

Effects on the market

Fewer sellers means less inventory, which can support prices even when rates are high. It also means buyers have fewer choices.
