There are companies that will supply coin-operated washers & dryers, service them and split the funds with you.Confused though, you stated you have a 4-plex, but that the laundry area supports 16 total adjacent units.

However, it does depend on what sort of investing you are doing and how your real estate market typically operates. 

It's a bit harder to find repair guys that work on commercial coin-operated machines and if it's isolated it could be a huge headache. 

Of course we would establish and talk through an operating agreement with an attorney etc.

Do you own all facets of the operation?

So, my question is: What are professional STR managers are doing to keep operational, maintenance, and cleaning issues to a minimum and everything running smoothly? 

Also, you want the insurance so that you can let their lawyers fight the lawsuit, otherwise you'll go broke just defedning your LLC.https://www.biggerpockets.com/...https://www.biggerpockets.com/...Then, there is the extra overhead with operating with a LLC. 

@Michael HutchinsonI’m sure out of state owners or self operators could use this service.

I honestly think it is the perfect platform for most operators until they need to switch to a Buildium or Appfolio type of platform.

They should provide you with a very clear & thorough breakdown of their businesses operating expenses, though they may not provide it until you've signed an NDA disclosure and made a formal offer.
