I'll throw in a little backstory.
Farmer owns 5 parcels of land. On one parcel of land he has a few barns and a 2 bedroom house. He leases this out to his sister who only uses the house. Under the lease agreement, upon death of the owner the sister has an option to buy the land and all buildings for $1. (There is no time frame in which she can exercise the option listed on the lease agreement)
Farmer wants a new barn. He gets a loan out against two parcels of land he owns, one being the one his sister currently resides on, the other in which him and his wife live on.
Farmer unexpectedly passes. Farmers wife now inherits the 5 parcels of land and remaining properties. She now owes the bank the remaining loan for barn he built in 2018. Again, the lien is against the land in which she lives on, and the land her sister-in-law lives on.
Is the sister still able to buy the property for $1 if there is a lien against it? If so, does she also take on the debt of the lien? And this question might vary from state to state (PA), how long is she able to exercise her option to buy-in?
