I'd be very curious to know on what you base your judgment. Here is a search on Airbnb for Summerlin Las Vegas 4BR/3Baths and I'd say $200-$250/night looks reasonable (apparently average is $429) https://www.airbnb.com/s/summerlin-las-vegas/homes?allow_ove...
There's a difference between what's listed and what actually moves.
You would find a 4 bedroom property in Las Vegas for $25 a night? Sign me up.
Where are you getting that from? The price seems totally in line with what’s actually advertised for properties on Airbnb. I don’t know anything about Las Vegas rentals though.
Really? For a week? 4 bedrooms potentially sleeps 8 people.
4 bedrooms can sleep more than 8 people. More like 12 possibly. All that matters is the beds layout and your willingness so try and max the sleeping area. This is from experience.
The intention is to extract value from your unoccupied home without irritating the neighbors/running a tenement.
