hunting down an abandoned property owner

[Heather Harrison]

Hi, I found a little gem whilst "driving for dollars" in my own neighborhood! SFH, winterized, vacant and in dire need of some TLC. After discovering the property owner passed away 2 years ago, and the mailing address belongs to the owners parents estate, I am unsure how to go about finding them. I know they live out of state. The phone numbers I found for them on BeenVerified lead to nowhere.

Does anyone have any advice or recommendations as to how I might hunt down the deed owner? 

Thanks!
