AFAIK, the posting rules for airmen, set out in the '70s still apply. This was that an airman would be posted to fulfill a vacancy caused by someone posted overseas, promoted or retired. At the time I knew a steward who was an SAC serving in the feeder at Cottesmore for 17 yrs.
I know a kipper fleet pilot who (as far as I remember) never served outside Scotland and rose to become AOSNI.
Many aircrew serve their entire career with one type on one base. It is almost the same with some engineers rising through the ranks to sqn ldr branch and being essentially a unit subject matter expert.
Given the quartering situation I believe it is not unknown for people to retain a quarter during the odd periods at the ministry etc. At a secret air base in Wiltshire one quarters occupant had installed his own patio, new fence, glass greenhouse, swimming pool etc.
