I just acquired the property in December, fixed it, and leased it in JuneThere have been a lot of items that they complain about like:AC not cold enough upstairs (this was repaired)Sprinkler busted (I believe this is a tenant expense but I fixed anyways)Water Heater not hot enough (I added a re-circulation pump, and didnt mind doing this)Saw too many bugs (It overlooks a creek and has a nice backyard view, but with that creek comes bugs so I pay for monthly pest sprays)Mice infestation (I paid for a comprehensive $6k package to take care of this)House cleaning (she didnt like the cleaning that the pest control did so I hired full house cleaning for her)Second house cleaning (for the end of the pest process, I have the maid giving me an update on if they're clean tenants or not)Mold Inspection (she claims there's mold so I did a mold check and it was 100% clean)Toilet Leaking (I paid for a plumber but isn't this a tenant expense?)

I am curious if anyone has a comprehensive list of cities that are friendly to/allow Short Term Rentals and any specific rules said city imposes (for example, Littleton allows STRs but has very specific rules related to property acreage, etc).

Wow, thank you all for such comprehensive responses. 

I have yet to come across a more comprehensive metric.  

Pleased to have found what seems to be a comprehensive site! 

Pay particular attention to the City's Capital Improvements Plan, which might be a separate document or might be rolled into either the Comprehensive Plan, the Master Plan, Transportation Plan, or some other planning document.The documents above usually reference 10 year futures and are updated every 3-5 years.

The current judge sitting on these cases in Providence right now is pretty liberal, and it is generally an uphill battle unless you have a comprehensive argument to present and a solid attorney presenting it.
