Hey @Calvin173 ,
I definitely understand where you're coming from with figuring out how to manage multiple properties. My wife and I are in the process of doing the same. Although we only have two so far, we have one in Maryland and one in California, so we definitely needed to have some type of management process that can sort of run itself and be easily scalable while being remote. With our current setup, managing two properties across the country is less work than handling one locally.
I personally recommend getting detailed checklists for your properties and trying to have them be as parent/child as possible. Every property will need 80ish% of the same supplies, cleanings, and maintenance routines to keep it going. That can be your general purpose checklist that you work from and then you have specifics split out for each property's special needs (maybe one has a hot tub, or one has a gas grill vs a charcoal grill, etc. Once you have this setup, you can use some type of chat platform to manage your team. Copy/paste your checklist there, and add your team. I recommend Slack/Discord for something like this so you can split this out into specific channels for each property. This way your team can always come back to this content without having to ask you every time.
I also recommend connecting with a channel manager to sync up your properties, cleaners, handymen, and calendars all in one place so that everything is automated based on your incoming reservations.
Sorry for the mini brain dump lol I can talk all day about this stuff. Send me a message if you want to brain storm or just have questions!
