The delinquinte HOA is grounds for the HOA foreclosing on the condo. You the tenant have rights. They must go through the full eviction process where if they want you out they will offer you money/cash to help you move. Tenants can stay without paying rent until the eviction process is complete. They cannot expect you to pay HOA fees on behalf of the owner and they certainly cannot put a lien on your property if you do not pay.
