Buying vacant property

I want to buy a property that has been vacant for 10+ years. The previous owners filed bankruptcy. Numerous investors in my area have attempted to acquire the home but nobody can find an owner. I thought about attempting to buy the note(s) instead but would need to find what company owns those. I would greatly appreciate any advice on what to do or who to contact for help.
Thank you

Look well before you leap.

Ten years, no maintenance, no care, dry rot, termites, roaches, water damage, all sorts of pests.

Is is actually worth the time and effort?

I do believe it will be worth my time and effort but I will do a thorough property investigation before finalizing any deal. I have a long background in construction and home building so that part of the project is a breeze. However, being a newbie investor, I am struggling to figure out how to buy the property. No body wants to admit they own the home so that makes it hard to make someone an offer!
I appreciate all advice on being cautious, but what I really need is help figuring out how to make the deal happen.
Thank you
