Quote from @Sarah Rosko: We manage several medium-term rentals as well and typically operate with a 30-day minimum stay.

If this isn't an attractive alternative to your business partner then you might consider changing the ownership structure or operating agreement as one of your options.

Heck go to the casino and put it on roulette wheel of black or red. 

Operations- tenants refusals, either cull them before they get to you by requiring autopay as an example, document on their application why you refused them, make sure your facilities are maintained properly and no safety hazards exist, etcLLC.

When funding is rare and flips are plentiful, there will be enough opportunities for everyone but return will be depressed and better operators will make better returns. 

An LLC is a smart move for individuals looking to protect themselves, grow their business in a professional light, and operate as a corporation. 

One thing I would mention though - doing STR just to save taxes often leaves you operationally unstable or too detached from the management to be successful.

Use an operating account for income and expenses, a reserve account for maintenance and taxes, and a high-yield savings account (HYSA) like Capital One's 4% APY for idle funds awaiting reinvestment.

Quote from @Carlos Lopes: Gross income doesn't matter.This is the number most people post, and it's 92.7% useless.What you need is NET income, meaning the money left over after all expenses, and that should include a dollar amount for your personal time spent operating the business. 

Also, depending on your long term goals, transitioning part of your portfolio into more passive investments might help reduce operational stress while keeping your equity working for you.
