Worst case get a double security deposit, a higher rent/guest/occupany fee, and make the SSN holder the sole applicant and the other adult as a guest.

As someone who was in your shoes as long time ago, with a newly minted finance degree, I can tell you to just keep going.

We own a local condo that we rent, and I serve as the property manager, which pays me $3000 per year to be the property manager (ie, self-employed, single employee, sole proprietor).

You own the real estate in an LLC so that could still limit exposure to business assets and not you personally but that is really circumstantial based on the fact pattern and jurisdiction and whether level of negligence opens the door to piercing the corporate veil (again very jurisdiction specific and circumstantial).I am a proponent of owning investment real estate in LLC's for the sole reason it keeps your name out of the docket more than if real estate is owned in your personal name and they are good tools for business planning.

There are definitely business opportunities for bookkeepers who can help landlords, because to create especially useful bookkeeping data, you need to analyze the performance of each individual property rather than your portfolio as a lumped-together business (though of course, for taxes you need that too...and for each entity if you've got more than sole-proprietorships like the original poster.

So, owners mistakenly think price is the only differentiator – and look for a PMC like they’d shop for groceries☹We encourage you to learn from the mistakes of others by reading posts here on BiggerPockets from owners that picked a PMC solely by price and regretted it.We recommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Even if someone gives you a referral, do NOT make the mistake of assuming that just because a PMC met their expectations, they’ll meet your expectations.

It’ll work fine, just means more paperwork and duplicate costs.Option 2 – Create a Missouri LLC just for that propertyThis is what most investors in your shoes do.
