Now hold on.

Now hold on. The man's house does not exist in a vaccume but within a state and the owner who owns it only does so at the pleasure of that state. In a sense the owner is maybe the one most directly in control over who can and can't come in but he does not have final say. That comes from the states monopoly on violence able to will themselves into houses under their jurisdiction given the right legal work.
You might say no, in which case is the owner of the house the only one able to invite a vampire in? No other person with access or implied authority can? No roommate, child, house guest? I think we can all agree that the vampire would be able to enter with those peoples permissions and I would argue the state has more actual authority to pick and choose who can enter the house than any of the examples.
This vampire cop is truly unstoppable.
