And cats can be just as bad for odors.

Be aware, though, this may foul up your Title Insurance policy. 

The tenants who live in the unit next to mine complained of an odor that smells like stale cigarette smoke in their apartment.

It was always plugged in so the odor wasn't too bad but it had food, meat juice, and sticky substances in every crack and crevice. 

I've spoken with only the selling agent which is probably a foul but I do have a contact of another real estate agent up there who is also a landlord. 

I would suggest talking to your tenant regarding the pet odor, to see if there is anything they can do to eliminate it on their end.

I personally fall into the latter because in my mind, the money on the low interest debt will have to be paid regardless...and if it's not hurting me to continually pay it monthly as I've been paying it, then there's no harm no foul.
