Seller is leaving everything in the home

[Hayward Bryant Jr]

Hi everyone!! I'm under contract to purchase a single family home for a fix and flip. To make a long story short, mom moved out of town, left the home to the son, son trashed it, left the house loaded with junk, and moved out. In the garage is a truck that's been sitting up at least a year. Decent truck, but not great. It's loaded with spiders, spider webs, and such. Despite the current condition of this truck, it's just nice enough to have a note that's not been paid, and a possible lien. In the contract, whatever is left after closing will be mine. I don't mind having cleaning up this mess, but what happens if money is owed on this truck? Will it too become my debt? Help me out guys and gals.....
