You should download the Minnesota Landlord Tenant Laws and become familiar with the laws so if you do decide to go with a PM you'll have the idea of what's required..

Your unfortunate story sounds too much like "Pacific Heights" (movie about a monster tenant and what can really happen when things go south). 

Downloading Utility PDF from portal2.

Just like scene in the movie :)Also don't expect tenant would take a good care of your property.

I recently downloaded the Delinquen tax list for Broward County. 

If you search WB-11 Wisconsin I bet you'll find a PDF of it and can download there.

Have you tried slightly lowering your rates to try and get some more bookings in, or have you recently gotten a bad review or two in a row, these are things that could possibly impact how much you are getting booked.I also could recommend that you get something that would make your listing stand out, such as a revamp of your furnishing and design, hot tub/pool, game room/ movie room, pool tables etc.Hope this helps you out, let me know if you have any more questionsBest of luck, Mike

Once you have that all hashed out, I would find a templated operating agreement online that you can buy or download free and then tweak it accordingly based on everything you discussed. 

You can download a free template onlineOther free websites I haven't used.Avail.coThis is another free website that I learned about this week listening to a podcast (may have been a BP podcast).

Lucky for me, I downloaded a copy of it all in order to generate graphs.
