@Joel McGinley there are a lot of great responses here already but I will add my own two cents after managing five properties abroad for the past 3 years, 3 with property management, two "self-managed" with some assistance by friends and family. First, those fees you quoted are expensive in expensive markets but by no means outside of industry norms. This is why I chose to manage the two I did with friends and family, because they are in that price range as rentals. The other three were in more B-C neighborhoods which required a lot more day to day interaction which a PM was much more suited for.
Judging by what you are saying about your rental, my advice would be to enlist a friend or two that is still in the area and willing to act in an urgent/emergency situation that may arise in your property. Arm them with a list of pre-vetted contractors (plumber, electrician, general handyman, etc.) and set up all the automation that you possibly can (a lot can be done for free through platforms like apartments.com). Give that a shot for two or three months and if it works, you're good. If not, you can always interview some PM companies remotely and have them take over. I think with high-end rentals your day to day management is really not necessary (in my experience) and you can save significant money if you try to do it yourself. Best of luck!
