., and is bickering the entire time during a showing-- showing up with rude, uncontrollable kids- showing up in a filthy vehicle- calling to tell me they will be late for an appointment because they're stuck in traffic - and I check Google traffic to find out there is no traffic jam - so, they're lying to me- using a relative as a reference- blowing off an appointment (automatic denial - they'd often then call for another appointment - uh, nope)- tenants going through a divorce (they won't end up honoring the lease and there is almost always drama with the ex)- being really picky during a showing - asking if we can change the closet to add another rod, or to change the paint color or can they have hardwood flooring instead of carpet, or will we pay for room darkening curtains if the street lights are too bright - these tenants will be constant whiners.These are all I can think of right now, but are all things I learned about the types of personalities that will cause problems. 

To me, one is an act of kindness, the other would be funding what equates to a gambling addiction.I'm glad I'm not in your shoes. 

I think @Mike Dymski brought up what may be the biggest uncontrollable variable which is having a consistently good PM.

Their gamble.  

At the end of the day, people are unpredictable and leasing anything to anyone is a little bit of a gamble.

I'd leave it at that, unless you want to gamble regarding them taking you to court.If your contract says you provide a working fridge, then fixing it would be on you anyway.But, you can sure charge them for cleaning it - if you did everything else right.  

If you are not making cash flow you are gambling on tomorrow instead of investing in today.

As both a short and long term rental owner I’ll just add a few words of caution here...AirBnB and other vacation rental sites like HomeAway are great for the purpose they originated: short term rentals, but they offer minimal protection for the concerns of many owners needing to secure their properties for longer lease terms.As a traditional property manager I’m far more interested in ensuring I pull a full criminal background check, speak with a potential tenant’s present and prior landlord, confirm consistent employment/income sources for > 6 months, and ensure a potential tenant has a track record of paying other bills they have agreed to in writing like credit cards, car loans, and others.On the contrary, at best AirBnB/HomeAway/others give me the following info on guest/tenant: a blurry selfie (that could be their dog)confirmation of a non-specific government IDconfirmation of an email address I can’t seecurrent city/state of residencelist of reviews by individuals running a different AirBnB (that I have no way of confirming is not the guest’s best friend)Property insurance secured by (and in the interest of) someone who is not meWhile I’m OK with taking a gamble on unknown guests using my property for short term stays, stays of longer than 1 month generally involve: Someone looking to move significant belongings in with them (that I cannot legally remove in most states)Moving in for a period of time they’re generally unable to pay for entirely upfrontTenants receiving access only after a legally-executed lease, criminal, background, credit, and income check that’s par for the course in a professional, term stay arrangementEven beyond the blatant lack of risk mitigation tactics common in long term lease agreements, the fact remains that many STR platforms are also skimming 10-20% of gross revenue off the top of owners’ profits for little beyond the initial SEO and payment processing.

Really, I have to agree with Greg on this one, as far as it being easy to deny them, and from my personal experience, it's worth the gamble.  

Or, the Landlord can take possession and charge them rent until he finds a new tenant.Requiring giving the tenant the choice of a termination fee or gambling on the other landlord options, is actually a tenant-friendly move for FL.
