It should be fine until you arrive. It will be a little shaggy, but definitely shouldn’t be out of control. Do not let your friends adjust your sprinklers. You’ll void what little warranty there is on landscaping if this is a new home purchase. Instead, ask if they’d be willing to contact the contractor who installed the irrigation to come and check the system and adjust the timer as needed. This is something that must be done within thirty days of closing unless you get an extension from Home Warranty. If pre-owned, definitely have your friends adjust as needed.

As to getting info on your neighbors, the best would probably be to have your friends leave a note with occupied homes asking them to contact you. Doubt they’d be particularly appreciative of a stranger contacting, even if claiming to be a new neighbor. If typical villagers, they’ll be knocking in your door almost before you move in.
