I think there's a pretty low bar for competency in the management business because it's not glamorous and can be a grind.

.: Quote from @Chad Hale: I used QB when first starting my property management business.

Sell your investment property and buy the land for your business. 

My wife and I are a team in our business too.

You’re running a business not a charity after all. 

Just my personal opinion - get a mentor or a person who already has good experience running STR business, preferably in your area (but not 100% required). 

You should be able to get a good feel for their knowledge and expertise through digital resources they provide (webinars, youtube videos, social content) Character - You need to believe they have your best in mind and they prioritize it.

In our 'day job' business of remodeling we have stayed just a partnership with an LLC.

That's why I would never had a business partner.

I find that it's almost a one stop shop in that I can use it for my business checking and savings accounts, bookkeeping, for rent collection, I can issue virtual credit card, I can create all the financial reports I need to run my real estate business and prepare for tax filing and through their partners I can vet my tenants, develop state-specific leases and more.
