Been thinking about this a lot since we run two short-term rentals ourselves with just AI tools and one VA, no property manager. Works fine at our current size, but I keep wondering where that actually breaks down for people managing more doors or a mix of property types. Is it purely a numbers thing, more units than you can physically handle, or is it more about hitting some specific headache, like handling maintenance emergencies alone, that makes people finally bring in help? Curious what pushed it for anyone here who switched from self-managing to using a property manager, or the other way around.
