Usually your contract will specify that your sponsor is responsible for making sure that the conditions of your rental contract are upheld.
There are two main reasons for this:
Remember that just because you can change your housing before the end of your contract doesn´t necessarily mean that you should. Landlord behavior is notoriously difficult in such situations - your landlord is likely to make the process as miserable as he possibly can.
Contracts usually call for advance payment in the form of one or two cheques, one of which is usually post-dated six months ahead. Employers often make rental payments on behalf of their employees, then deduct the cost from the employees´ salaries
Most rental contracts demand that property be returned without damage. Any damages must be repaired or replaced by the tenant. In addition, contracts usually contain provisions regarding "anti-social" behavior, which allow your landlord to evict you if you irritate your neighbors, party excessively, or otherwise disrupt the daily lives of other tenants.
Still, most foreigners come to Oman with full knowledge of landlords´ and neighbors´ high expctations, and therefore remain on their best behvior for the duration of their stays.
Furnished apartments are equipped with a wide range of goods, usually of reasonable quality. A copy of the inventory will be provided along with the contract, and it will be checked again when you leave.
You will be charged for any property that is damaged, destroyed, or missing. If you are ignorant or clumsy enough to seriously damage your rental property, don´t expect to get your deposit back.
