PTDY can be used used for job hunting and/or house hunting. If you have a job, then you need to house hunt. I belive its rule 4 on the PTDY table ( i dont remember the reg but thats the info on my terminal PTDY pprwrk).
As its been explained to me, because this same rule only authorizes either house or job hunting, actually working the job isnt allowed. You can work on terminal leave.
