Tenant noise over landlord

[Travis Oakes]

I have a situation, I am house hacking a 3 family house and I am living on the 2nd floor. My 3rd floor tenant keeps to himself and is a older gentlemen. However, most mornings I am woken up by him walking and the floor is really creaky! And most mornings he will start moving/walking at 2:30am-6am and it’s so loud it wakes me up and I continue to toss and turn and not get much sleep.

What can I do? What should I do?

P.s. his rent is low for the market, only paying $625 a month. His unit is outdated b/c he’s been there for 15 years!
