Did some work on a leaking faucet, got rid of some old furniture and replaced it with new, made a ton of tasteful decorative updates to decor.

They let it wander loose in the house and it dug or chewed the carpet under the furniture.

Furnish it with decent furniture from Cost Plus or Pier 1, and furnish glasses and dishes and pot/pans etc, then try for a family who is transferring in or an upscale or corporate type.

Provide felt furniture sliders for heavy furniture items at move in?

They don't buy chic furniture.

In the last LTR I bought (and converted to a STR) the previous tenant was a tweaker/hoarder and couldn't afford to pay his gas bill......so he starting burning furniture and kitchen cabinets to stay warm.....

Everyone who owns an older home has dragged all the soggy belongings (furniture, appliances, clothes, toys, knickknacks, etc.) out to the streets which are covered in mud, and there are downed trees, fences, pool cages, boats on front lawns, a major mess.

I had one with almost a dozen home sin a dozen states AND each with full identical wardrobes and furniture at each, lol. 

I used these on hard surface floors and have been glad I did (they get beat up but the floor underneath is preserved).I also advise tenants on having a rug/ pad/ protector under any sharp furniture legs and to look out for gravel stuck in your boot, etc.An added benefit: on the turnaround you just sweep/vacuum and damp dust/swiffer the floor and it is ready for the next tenant (provided it did not get damaged).

I should add that an agent who fits all of the above criteria I defined will ALSO have a vendor list of lenders, inspectors,  handymen, cleaners, flooring guys, furniture stores, etc., etc. so you can start building your team immediately.
