Lock-In Effect
Definition
The phenomenon where homeowners with low mortgage rates refuse to sell because they'd lose their rate advantage, freezing housing market liquidity. Particularly strong for borrowers with rates below 4% who would face 6-7% rates on new purchases.
Example
You have a 3% rate on a $500K mortgage ($2,108/month). Selling to buy a $700K home at 6.5% would cost $4,423/month—a $2,315/month increase. This "locks you in" to your current home.
