Every PM I’ve worked with (3 so far) has been a smaller outfit with a handful of employees.

One of the turn key outfits I fund in Indy .. they do something similar .. some sweat equity.. along with start the carpets in a beige color then in every turn over they just progressively die them darker until they change them out.. cheap to die them.. you know some how these tenants just cant cross a room with out spilling their big gulp or their coffee.  

Many of those TK outfits make profit when they sell and PM is something they do to get the sale to happen.

Shortly after we went under contract the 200k res next to it close to a gold mining outfit!

For outfitting the house I found a room-by-room checklist that showed essentials, I believe I searched Google for AirBnB checklist.

I would suggest looking in the rust belt and mid-west .... you could get 8 SFRs, 6 duplexes, two quadraplexes or one octoplex for the price tag of that 250K(ish) duplex you've been considering.Ironically I had a cold caller today from a turn-key outfit in Columbus.  

The more I think about it, that would be really fun to have a STR outfitting like the 80's or 90's and a place I would love to stay at! 

Lots of bigger outfits do well with these mediums.

I can't speak to this outfit, but often times these things are just marketing tactics.

Find that outfit in your area.
