Colorado lease Questions

[Justin Calahan]

I am planning on purchasing my first property this year that will be a house hack, however for now I am still renting as I travel for work. 

I have a landlord in Colorado who we agreed in emails that after my lease term we go month to month with 30 day notice if I am to leave. Now they say that doesn't matter and I need to sign more paperwork. Is this actually legal? 

Also, this particular person sent me information on every tenant in the building including names, where they live, their rental amounts, and contact info. I don't think I should have this information. This particular person seems like they are trying to do some shady stuff under the guise of the law, and where I am is a small town so there aren't many options. 

Any advice on what I should do? Thanks.
