Buying a tenant-occupied condo

[Chris Oei]

Hi all! This is my first post ever on Bigger Pockets.

So I see on the MLS there's a condo for sale by an investor, and the condo is currently occupied by a tenant who intends to stay there. I'm totally new at investment properties and I'm wondering: what are the chances the tenant is behind on his/her rent? I mean, it doesn't sound promising to me, but what do I know.

Do investors who purchase an occupied investment property typically ask for (and get) the rental records? And if I get them, is there a way an investor can verify those records independently?

Thanks in advance for any help or advice,

Chris
