Are abandoned houses unoccupied?

It is a deflection.

To be clear now, they're now relevant enough to know how many in each category?

Let's just give this the sniff test:

Ok, you dismissed abandoned houses as irrelevant because you didn't know how many there are

There are various reasons why a home may be vacant, including that they’re up for sale, in probate, under renovation,

You think these ones are relevant because you did know how many there were?

Can you see why it's a deflection? It doesn't matter to your position how many there are. You, at the time, didn't know how many there were of any of them, but you made a distinction anyway.
