The code, regulations and rulings do not have any specific holding period. 

If if they're advertised they're real especially in today's crushing over-regulation mortgage industry.

As you get closer to heavier population it seems more regulated. 

I don't think there is a lot of regulation on what ls legal for transient occupancy, but typically if it's not considered safe for a tenant, it's also not safe for an Airbnb guest.

I have another property that needs extensive rehab and there are a few inherited tenants that would not pass our regulations for screening from what I've gathered so far.

Out if state and foreign investors may be the new norm in primary MSAs  at least for awhile since bond yields are low (for out of state/institutional investors) and the since US markets are so much better regulated and trustworthy (Foreign investors) The former may taper off, but the latter won't change for awhile.

Then I use this data to make a more informed decision on where I buy, how to furnish it and market the unit.I don't know the local laws in the Twin Cities, but it is import to learn the local regulations if there are some, and fully understand the local sentiment towards short term rentals and if it will potentially change.

@Jesus Moreno I found the New Mexico Regulation and Licensing Department web site.

@Nick G. one of the things I did not consider when looking at LD investing was the differences in taxation and landlord/tenant regulations.

@Paul SchaefleI would start by contacting the village and or Hall and see how they regulate and if they do regulate short-term rentals.
