Would you rent a condo from VBRO with no ratings? It's on Maui, and managed by a property management company. It looks nice, is on Wailea Beach and the price is right.
I only stick to VRBO properties with lots of reviews. But since this is a Management Co, I'd google it and see if they have a legit website. If so, I'd feel confident booking.
I might make a phone call and ask a few questions just to feel the management company out before booking, but that wouldn't prevent me 100%. We've done enough VRBOs without problems that I tend to think most are OK (though obviously there are problems with some, as evidenced by recent posts!).
Try searching the tripadvisor forums for the condo name or management company. I've done that before and been fine, but if I can't find anything online about the place I'm trying to rent, I find a different place.
