live out of camp option

If you choose not to take the Aramco assigned house and live off camp, yes I think you would be at a disadvantage when trying to relocate later back into the camps. If you live outside Aramco housing your children are not eligible to attend Aramco schools.

Your children must be accepted by the Aramco schools prior to them receiving a visa. Or you are asked to sign a form stating you are responsible for getting your children enrolled into a different school somewhere. Once here if you choose to homeschool you can do so, homeschooling is not an official option, but is allowed. Although all the support groups for homeschooling are not available in KSA or Aramco that you would have back home.

Anyone with GC 11+ Aramco ID may use the facilities in any Aramco compound. Below GC 11, have their own recreation facilities that can be used with an Aramco ID.

Do not know prices for bachelor housing outside camp, but have heard that most places ask for 6 months to a year's rent up front.

I recommend you take the assigned housing first. Then if you want to look for outside camp housing you can do so at your leisure and find what you want or you may discover you want to keep the Aramco housing.
