Another idea, make it so that the more single family homes someone or a corporation owns, they pay a higher tax rate on all their properties. So someone who only owns two or three SF homes they maybe pay 1.5%, but if they own 20 they pay 5%. Similar rules could apply for apartments or condos but with different multipliers. If set properly it'll be impossible for large landlords to pass those taxes on to tenants, because they'll be undercut by smaller ones and buyers who just want a place to live.
