Hi,
after switching from Evolve, I didn't bother to buy or transfer reviews from them. felt like more of a hassle doing it. They do sell photos/descriptions after your 90 days time with them.
I have used Guesty for hosts, since I currently only manage one property(I have mixed opinions on this, few things to note are that VRBO integration can be an absolute pain, scheduled messages can be a hit-and-miss (you will have to disconnect and reconnect at times), you could potentially choose hospitable/hostaway/guesty for pros if you need more robust PMS.
One thing to note is you will have to learn a little bit of dynamic pricing( pick and choose your favourite and try them out before settling) pricelabs/wheelhouse/guesty price optimizer
Once you start managing yourself, you will thank yourself later for the money that you will end up saving. The only thing to keep in mind is finding a reliable cleaner(make sure you have good communication/backup plans), and a good handyman.
understand your market and do the switch in a slow period, that way you can get experience and not lose a lot trying to figure it out.
I have learnt a great deal from bigger pockets, and lots of helpful people here. when in doubt ask and be specific to get the quickest answer :)
