How do I track down owner of abandoned house?

[Syed Ahmed]

Considering purchasing a house. They are asking 90k, but I feel I can get for 60k, and mostly cosmetic repairs. Comps of nearby homes sold for over 115k last year. The house next door is empty and much larger. Windows are broken, and I have driven by a few times with no signs of life. My question is, gle do I track down owner for potential sale and two, should I even consider the first house since the abandoned house will make it harder to sell first, since it's right next door.
