who pays condo fees

I recently moved to a home that unknown to us is in the process of foreclosure. I was approached by HOA and was told that in the state of Florida the law is that if a home is in foreclosure and the home owner rents it out the rent will be given to HOA to bring condo fees up to date. I refused and they told me they will deny me access through the security gate and will turn off water and stop lawn care. I tried to just pay the monthly fees and deduct from rent and pay landlord the difference. No they want it all..whAT TO DO??????????????????????????????????????
