How to find details on an off-market house

[Wesley Wilk]

Hey folks. There’s a house in the neighborhood that I walk the dogs in that is fairly neglected.  It doesn’t appear to be occupied. Very unusual for this street. Zillow says it was last sold about ten years ago. 

How can I go about finding more info about the house?  Like if it’s in good financial standing and whatnot?  Courthouse? Tax office?
