I've allowed pets in my STR for five years and haven't had any problems except some extra cleaning a couple times, which was paid for by the guest. 

Their biggest challenge was finding a reliable cleaning crew, but once they built a team, everything ran smoothly.Let me share another example.

You can even "pay yourself" the cleaning fee if you want to and do the turnovers yourself. 

There thinking some clean-up-fairy comes swooping in with a broom, washes the ashes away and then Bob The Builder n all his friends comes hot on the hells, Bing-Bang-Boom all is rebuilt and were singing kumbayas by Christmas.......Reality is it took about 10 years to rebuild post katrina. 

Maybe you can add clear rules on noise, guests, shared space usage, cleaning responsibilities, maintenance expectations, and specific guidelines for shared bathrooms/kitchen.7.

OP said: It’s frustrating, especially because our due diligence came back clean, leases were solid, and the property had just been fully renovated.

Or are they moving out when the cleaning is complete?

Few left were broken, never cleaned.

Consider cleaning, lawn care, snow removal and supplies as well as utilities  in your calculations.
