Aren't most people who are "locked into house" a seller that's removed from the market, but also a buyer that's removed from the market?
I can see how someone who decides to keep their current house to use as a rental and buy a new owner-occupied property would tend to increase house purchase prices slightly (but also increase rental availability and lower rent prices slightly), but also think that’s a tiny minority of current homeowners.
