It is a completely different game once you bridge a serious gap in the market. there are 3 kinds of houses in the US:
1) Homes people buy because they need to live somewhere and they can afford to buy this house here.
2) Homes in which nobody who could afford them would live there (rental only, think slumlord to casual investor to real-estate get-rich sucker)
3) Ultra premium. Houses so far above the cost of living for an area that you cannot buy it if you work for a living.
These all have wildly different real-estate agent behavior, and most people will only ever deal with #1, and maybe #2
#1 are 6% commissions with realtors who will be a realtor for an average of 5 years, any "staging" they do will be cheap or free, and mostly your commission is paying for their time.
#2 are square-foot checklists, repair lists, inspections, and flat broker fees. An agent might list on MLS and coordinate with inspectors... nothing really outside of that.
#3 People have no imagination, and they simply won't buy a premium/high-end house if it isn't staged. They aren't buying a house because they have to live somewhere.
a 10 million dollar+ house will be staged with a half-million dollars in furniture, art, dishes, towels, etc most rented, some owned by the realtor or their group. Any drawer, closet, or cabinet that might be opened, will have items in it that convey a luxury lifestyle. Leather-bound books on the book cases, electronics, toiletries, everything.
They might even hire a chef to put freshly made food in the refrigerator to be thrown away after a showing. I am dead serious.
They might learn that a buyer likes purple and replace all the flowers in the landscaping with purple pansies.
They will definitely put fresh cut flowers, fresh fruit, etc out before every showing. Spending hundreds of dollars on disposable goods every time they unlock the front door.
I worked in risk assessment for in the real-estate industry for years. Once for a listing in Malibu I had a 6 million dollar insurance policy go through my system... covering JUST THE ITEMS USED FOR STAGING. It included a Ferrari... Used for staging a garage.
