My landlord has refused to maintain the building im renting from him, and is now taking us to court?

for non payment of rent, we have a very strong counter claim, but very litle money. he now states that he has deep pockets and will wait for us to go bakrupt. If we were to on with the case an win he states he will go bankrupt, the building is morgaged to the hilt and owing moneies to his other companies. he will then buy back the building from the liquidators at a discount price and start again. what can i do?
