The effect on housing prices of changes in the proportion of institutionally owned single-family homes ares likely to be second order compared to more basic supply considerations.

Larger owners may be more likely to use tools enabling algorithmic collusion. They may also deploy sophisticated strategies to create concentration in markets (e.g. university campus neighborhoods) that escape antitrust scrutiny because they are small but have inelastic demand

"Affordability" is the user cost of ownership, not house prices. Banning large institutional investors reduces liquidity which reduces the cost of buying a house but also the value from selling one. It would also raise the cost of renting a home.

Institutions own about 1 of every 300 single-family houses in the US. Removing a single potential buyer in 0.33% of sales will not have any aggregate effect.

Maybe a small, probably temporary effect. Doesn't address constraints to increasing supply.

This seems pretty small in terms of any mortgage interest rate effect, which could be partially counteracted by lower rates being capitalized in prices anyway.
