If you sign a rental agreement for 12 months, the standard payment terms are to pay 1 month rent, plus a security deposit equal to 1 month rent. However, if you sign a contract in the busy summer season, or before it, the owner may ask for a larger deposit or charge a higher rent for the summer months. This is because rental properties are extremely valuable for summer rentals, so owners can be wary of giving a lower 12 month price, and then having the tenant leave at the start of winter. Please keep this in mind.
