If you sign a non-renewable contract (which is what he wants) I believe you will not have a case against the landlord in the eyes of the RC, and 1 year down the line he will be entitled to get you out. You will then have to find another place, at god knows how much more money it will cost you to rent an apartment in Dubai next year with rents continously going up! If the contract is renewable, then he can only kick you out if he prooves he or a member of his family is moving in, which is usually not the case, you are also allowed to stay a second year without increase on your rent, and he can only put up your rent by a 5% as per current rules.
I strongly suggest you do not sign a non-renewable contract!!!
