They have the right to be paid with a check that doesn't bounce. After that, no, it is no longer thier property.
They have no right to determine to whom they wish to sell their property?
Isn't it within the property rights of the seller (the person who actually owns the property) to sell to whomever he wishes?

They have a right to sell to who they want without discrimination. You can't refuse to sell to a gay couple, or interracial couple, or jews, or muslims, or black folk, etc.
If your idea of the right to decide who to sell it to involves restricting the property rights of the new owners (especially if they end up with less rights than you had as the owner) then there is something seriously and fundamentally wrong with you.
