Hi there,
welcome to jordan, Khalda is a good place to live but its somewhat crowded, on the other hand all services are available in that area meaning you can get lots of your errands done in no time.
Yes its a bit crowded, usually °µÍø½ûÇøs live in places like Abdoun, Jabal AL-Lowaibdeh and 4th circle all of those °µÍø½ûÇøs are mostly diplomats so its kinda pricey, you might get a good deal if you searched enough.
Best of luck
