Falsified documents at close

[James Godbout]

Hell,

We recently closed on a 3 family, commercial loan to an LLC. Our new tenants are all claiming that the leases and e-stoppels provided to us / our bank during the mortgage process are fake. One of the tenants had a security deposit that was not on the lease or on the e-stoppel, and the other two tenants claim they pay $500 less in rent (each) than the leases / e-stoppels show.

I'd love to know what legal options we have here, particularly to go after the seller if the documents are falsified.
