My 'landlord' doesn't own the house I'm renting - what rights do I have?

After signing a contract for 1 year in November, we recently have had mortgage company employees knocking on our door saying the house is owned by them. After speaking to the landlord who assured me it was fine and that he did own the house, we received a letter today saying that unless we or the so called landlord can provide legal documents showing that he owns the house, then they have a right to evict tenants ect.

I don't believe the landlord anymore and have zero trust in him so would like to break the contract. Due to him not telling us that he didn't own the house, do we as tenants have any rights to get money back ect. And this illegal for the landlord to rent a property without owning it?
