Lender backed out after closing docs signed

[Ryan Weimer]

Was supposed to close on a 4 plex Friday 3/20.  Final closing docs were late getting out to me but were signed on 3/19 evening and shipped the next morning.  Disbursement date on the docs was 3/20.  The docs did not arrive in time to title to close on 3/20, so I got a 2 business day extension to close (3/24).  As of this morning, everything was set to close today according to title.

As of an hour ago - I received an email and a call from my lender that they were suspending funding to all loans because of COVID19, including my file.  I am going to lose this deal and wanted to know my rights here (if any) for legal action.  I have never heard of a situation where I am cleared to close, final docs are signed, and the lender just refuses to send the wire.  Any thoughts out there what I can do?
