Regarding Accommodation

Jatin there are plenty of other threads on this if you want to search - in general:

1. The north side of Jeddah has many malls - so if near airport you are also not far from many malls

2. Costs- depends on lifestyle, what you eat and where you shop, how often you eat out etc. Imported goods are more expensive than local - markets/souks are cheaper than big shopping centres like Red Sea Mall.

3. In Jeddah family places are abundant - most restaurants have family areas - amusement parks are for family - there are beaches also for family........... if a local Saudi establishment your wife will need to wear abaya - so in restaurants/amusement parks but at some of the beaches which are western she will not have to to wear it.

4. Taxi cost will again depend on where you go and how often. Local taxis are cheaper than private taxis but they are also a little more dodgy! In a private taxi service you will pay about SR30-40 for a 30-40min trip, local taxis can be cheaper.

Can't help with rent.

JK, Al Sharafiyah, Aziziya & Al Hamra are really far from KAAA INT'L terminal. If you choose to live in those areas it would cost you around SR100 for taxi ride -round trip-, though the rent in those areas are relatively cheaper than the north side of Jeddah. In Azizyah you will find the majority of the residences there are Indians and Pakistani, you will find a lot of Indian/Pakistani stores there.

I hope I offered you a good advice, don't hesitate if you have more inquires  .
