Hello fellow filipinos. In case you are going to work in Jazan (Jizan) be prepared for a surprise. Besides from being backwards and ugly as compared to other cities of Saudi Arabia, the cost of room rent is also very high. One room without a kitchen and separate toilet will cost you 1000 riyals per month. I you want room with kitchen and bathroom you should be prepared to pay 1500 riyals or more. Why is this so? Because Jizan was left behind during the previous boom years in Saudi Arabia and the buildings here are new. This means that the cost of construction of this buildings is higher as compared to the construciton cost of older buildings in Riyadh, Jeddah, Taif, etc.
There is also no intercity bus so everytime you move you have to use taxi which are also charging much higher rates. So consider these things when you are negotiating with your employer for housing and transport allowance.
