This all sounds bad. First, the change in rent, that is a red flag and you should have ran. Second, are you responsible for the utilities or is the landlord responsible for the utilities? That would have told you who's name goes on the utilities. Most tenants pay for all utilities. FHA is just the type of loan the landlord has. It could be he bought the home as owner occupied to get a better interest rated on his loan and cannot rent the home out for 2 years?
