The way to handle this, which no one seems to be willing to face, is to make laws that are not wealth-neutral. If you are a mom-and-pop landlord (with a relatively low net worth), your should have more leeway in dealing with tenants. If you are a large landlord, you should have very little. Couple this with ruinous penalties (e.g., full forfeiture) for attempting to hide the true beneficial ownership of the property.
