I rented a basement bachelor suite in a house, but now I remember that there is a dog upstairs in the house. Is this haram for me to rent?

I have been struggling quite a bit in my current shared accommodation. My non-Muslim roommates are dirty and listen to music (often during prayer/salah times). So I've been looking for a bachelor suite for myself for a long time. I've just found what I feel is a very, very good deal - an affordable place in a really beautiful neighborhood. I've paid the security deposit and I plan to move in next month. I now remember that the landlord who lives upstairs mentioned he has a small dog (i.e., not a guard or hunting dog). I am now all over the place gasping for air. I know having a pet dog in the house is prohibited and that angels don't enter homes with a pet dog. My question is, does that apply to me? I have a separate basement suite and it has a separate entrance. I am willing to let go of the deposit and look for a new place if it is indeed haram for me, but I want to be sure. Can someone point me in the right direction. Maybe a hadith that talks about a dog living in the premises but not in the person's direct apartment?
