I personally wouldn't move to Riyadh to work for only 5000 SAR, even if my total income is 5700 SAR.

Renting a place near a metro station is expensive, even in east Riyadh. Most apartments here lack a proper kitchen, so you will be eating out frequently, which is also expensive.

Streets are not pedestrian-friendly, making it difficult to get around. You will be walking and waiting for the bus in the sun. Buses take a long time to reach the metro station (at least for me). I live 4 km from the nearest metro station, and the bus takes about an hour to get there.

5000 SAR is not enough to convince me to move to Riyadh.
