The legislation, known as the Homes for American Families Act, would amend the landmark Sherman Antitrust Act of 1890 to make it illegal for investment funds with over $150 million in assets to buy single-family homes, condominiums or townhouses. It doesn’t apply to homebuilders that are constructing units for sale.
Anti-collusion laws could just as easily be part of the system. With mandatory jail time and fines included.
Then again, laws about this issue probably need to be studied and verified for their effectiveness and to see how the market and how nefarious people will respond.
