I’ve had realtors/brokerages ask me for a $500 “paperwork/storage fee” as a buyer.

What factors would make such an option more attractive?

@Scott Anderson-  If you are able to obtain a large  credit from seller - I would  recommend  using this to " buy down the  rate" ...if you have no credit to  work with - I would recommend  using a  0 fee / low loan fee  option  to close the loan  ( with the  premise that  refinancing will be an option in the next few yrs ) 

A small fee and possible annual inspections .

Your difficulty and cost will be based on many factors.

I'm looking for opinions on flat fee listing services.

So, the first question they usually ask a PMC is about fees - instead of asking about services and HOW those services are executed.EXAMPLE: PMC states they will handle tenant screening – what does that specifically mean?

@Bret Kingcade I’ve never heard of inspectIng a carpet with black light Were you paying a pet fee in addition to your rent?

Typical property management fees for long-term rentals are anywhere between 6-12% of rental income while fees for short-term rentals can range between 20-40% of income.  

However with credit card payments they do get hit with a fee unlike ACH payments which are free.
