re: Flood Rental Eviction Question (what would you do?) UPDATE

A renter is entitled to a reduced rent based upon the condition of the unit. Your lease has continued on a month to month period.

Obviously, I would stop putting money into the unit. If you know an attorney, have them send them a letter asserting your rights. Document all work done and expenses undertaken in good faith.

No way a judge sides with the landlord here, but you need to get an attorney.
