You can always not be there.
As for the light bulbs, do you use energy savers? They last sooo much longer than old-school bulbs.
Personally, if I had a property I hadn't seen for 2 years I would want to check it out too - especially if there were some bigger issues like the door and tree trimming that had been requested, I would need to see if there was anything else to be done etc.
Good on the RE for giving you some warning too! So many of them would jut not have bothered. Sounds like you have a good one there.
