Yes. It should clearly state the monthly rent, the security deposit amount and conditions for return, what’s included in the rent (for example, are utilities or Wi-Fi covered?), the length of stay/notice period, and any specific house rules or restrictions. This protects both you and the landlord (or main tenant) by ensuring everyone knows the terms. Also, confirm that the landlord has approval to rent out the room (especially important in HDB flats, where there are rules on room rentals).
