Possible purchase help, help me avoid a trap

[Nick Sotelo]

I found a home that is in need of significant repair. It appears that it was at one time repurposed as a multifamily with possibly three units,  but two for sure. 

This home was sold a year ago via a Trustee sale. It is now owned by an LLC in a different state.

I made contact with the LLC via their lead capture website asking for them to sell the house to me.

I got a reply stating that said "I do owed the property subject to the 1st lien. Make me an offer and we can go from there." 

I checked the county clerk and I don't see any active liens. What do I need to be aware of before making an offer on this house? I'm trying to avoid forking out some money only to find out someone else has a legal right to it, rights of redemption or something like that. 

I'm itching to pull the trigger on this. Help me avoid a trap.

Thanks!
