Is the unit you normally rent managed by this property manager? If so, and you have had no complaints about your stays in terms of the unit being clean, well-maintained, and the communication being good, then you might want to continue with them.
Otherwise, I would thoroughly research the managers, look at their reviews, etc.
Inany case, make sure that you retain control of the listing, do not allow any management company to be the listing administrator, just the co-host.
Otherwise, if you decide at some point you aren’t pleased with the managers, it becomes a mess to get them to unlist it, and you would have to start the listing again from scratch, with no reviews.
Also be aware that listings and reservations are non-transferrable. If there are current pending bookings when you buy the place, they will not be transferred to you, the seller has to cancel those bookings or refund the guests and tell them they can rebook with the new owners.
