Question regarding lien and expenses

[Santosh Prabakar]

I'm under a contract to buy a fixer and spent a bit on inspection and various other expenses.

Title company notified me the property has liens and the seller need to bring in additional funds around 20k to close it. The liens were not disclosed in the disclosures. 

Is there a way that I can recover the expense from the seller? I'm still very interested in the property if the seller can bring in additional funds to close.

Just looking for general recommendations from the BP community.
