my cousins are staying in a campound. 2 bedrooms and are paying arround 18000 per year.
trust me, there its better than doha to save money, and its good that u have ur family with u, so no one will tell u u cant go to the mall if u r not a family.
food u dont have to think about it. its cheap as well.
local people in Qatar they go to KSA to buy cars and bring it here, cause u cant compare the 2 prices.
jeddah its kind of open minded city, girls they dont have to cover the head.
trus me, there u will save much more than what are u saving here.
