Seems like the tide of STR regulation in Colorado is in the direction of restriction not permission.

Such use does not violate subdivision restrictive covenants.2.

But I guess as Drew suggested the restriction is also from the screening provider. 

Lack of supply is mostly purposely created by outdated zoning restrictions, paranoid nimbys, inflation, and our economic system in general. 

Dont like the cut-throatness and nastiness within some offices of some of the big "boiler room" firms and some of the restrictions on territories and property types, but cant afford to sacrifice actual success if thats the type of place you gotta go through, at least at this point in life...  

I would really like to continue to invest, although with the interest rates, the restrictions and prices in Canada it is a challenge. 

are there any restrictions on number of rentals?  

However, be cautious about the LOC's terms regarding real estate investment use and potential restrictions on refinancing.

First you would need to check and see if the area isn't restricted for STR, and the market is there to support a STR.

Consider both county and city restrictions that may affect certain neighborhoods.
