House hacking law

[Muhammad Ahmad]

So for house hacking I know a person needs to live in the property for at least one whole year before moving out.

Let’s say I house hack a property for which my cousin is going to pay for the down payment. In this situation he wants the property under both of our names.
Now he is married and can’t live in property, however I can. My question is, since the property is going to be under both of our names, do both of us needs to physically live in the house Or I can only live in the property and he can live where he is living right now. What does the law say (since property will be under both of our names)

Any feedback or comments will be highly appreciated.
