This really isn't that difficult when you stand your ground and remind the tenants who the real home owner is.Tell them that you are going to schedule open houses and they are responsible for removing their valuables and/or locking them up in the closet or off the premises.The realtor will escort each buyer throughout the property so there really isn't anything to worry about as long as they keep their valuables out of sight.No one is going to open their dresser drawers or touch their clothes and stuff with an escort watching them.Never let a tenant dictate anything to you ever.

I furnish the house with the stuff they need for living like beds and dresser drawers etc, then play property manager and get the lawn then care of and such.

No bottom bunk and a large dresser in it's place.

They have a dresser for the rest.Like this:

I did one property in a duplex nice, but nothing fancy, the other side I called the Bunkhouse and put all kinds of Cowboy ornaments in it, like tables with horse legs, western logwood couch and bed, wagon wheels, varnished pine baseboard and trim, stainless steel appliances, hickory hardwood floors, antique oak hutches and dressers,walk in tiled shower with horses depicted on the shower curtain, elk antler lamp and mirror, etc. 

She said she's a hair dresser. 

My wife had her hair dresser in Progresso, MX, 7 miles from our home.

Storage is critical and I would hate to have to walk into another room to get my clothes. buy a dresser/wardrobe?

I’ve looked online but I haven’t really read about why are good setups for rooms(bed size, night stands, dressers, mirrors???)

A bed a couple of dressers and scattered toys remain.
