If I were reading reviews on a vacation rental with negative comments about the management company, I don't think that would sway me at all. If a reviewer says that management and staff were great, that's a positive, but a tiny component of my research and decision.
In our case, The owners supply a desirable house with basics we require from our pro experience ( example white 100% cotton linens). They pay their mortgage, insurance and taxes; we handle 100% of guest experience. I own many of our properties as well as manage for absentee owners. I also traveled exclusively for about 20 years using vacation rentals.
This has been an interesting exercise for me . Your opinion and all those above have been been tremendous food for thought. I am very grateful. I can't find a citation at the moment but I heard a news story last month or so about a proposed congressional bill to create some oversight of reviews on amazon. (if I recall correctly--- some products on amazon, once made by supplier A was utilizing reviews now manufactured by supplier B. Of course in this story, supplier B was a far inferior product). regardless if my memory is correct on the story, it's poses an interesting question, yes?
Online reviews are not going away anytime soon. They are a vital part of our new society. This is new frontier stuff.
All that said --- I went and looked at the new VR rental listing (paid advert) of new PM company. All our reviews are there "4.9 stars! 67 reviews!" , but each one NOW states "This review was made while under different management". Maybe it took a while for that feature to get published? Maybe VRBO heard my entreaties and made a change? I don't know. But this is totally fair and I am at peace with this now.
Great community here; Many thanks!
