done the VRBO and indirectly the Home and Away is it was linked within the VRBO description.
I looked at Air B and B for a few ski towns but in checking, a large share was a property management co. I don't mind but I'd just assume go direct.
For VRBO, have good experiences but I normally will check with the county or city assessors offices on who the owner is, etc to see if things jive. however since most sites let you pay them with assurances, worry a bit less these days if booking. Overall I've noted for places I've booked, the owner isn't trying to fill it 100% of time, seems more so just offsetting cost of second home. Rentals I've made from a property agency seem to be units the owner only visits once or twice a year so they're using property management to fill as many days possible.
