I attended a workshop hosted by a large business advisors firm.

Throwing three sets of strangers in a house without a host onsite is a recipe for disaster.Guests who rent rooms tend to cause more problems than guests who rent entire places.

I know many hosts have completely recouped all their down payment and furnishing costs within the first year just by doing a cost seg.

At the very end of the description, you say "This is a hosted rental." 

At least people have ratings on the OTA and I can see if other hosts have had issues.

Either the owner or the co-host will need to live locally in order to register.

To me this makes sense because a one bedroom can host 1-2 people easily with a competitive ADR and cleaning fee, while 4+ beds can host multiple families and split up a higher ADR between more adults. 2 bedrooms can be price competitive with 1 bedrooms and attract the same guest avatar plus small families or 2 couples. 

I enjoy hosting and like to be the first point of contact with my guests. 

My name is Mercy and I am a virtual assistant and co-host for short-term rentals.

This is why I highly suggest hosts check into the info Justin Ford has, and the educational videos and course he provides.
