Is there anyone well versed in Colorado law that can answer a few questions before I consult with a lawyer?

Are you more interested in short term rentals (thinking about opportunities to co-host STRs)?

My judgement is that I thought you couldn't do 1031 on personal residences but I'm not sure how you're classifying the co-op you've bought (most people that buy co-ops use it as primary residence). 

Colorado landlords will no longer have free rein to refuse to renew their tenants’ leases under a measure passed last month by the state legislature and signed by the governor.

Good luck, I'm in CO if you land here!

I find house-hack options Denver and Colorado Springs every week.

Any ideas for getting a loan funded, finding another co-borrower/how that would work for a deal split, etc. 

We have a real estate meet up in Colorado Springs that will be great for meeting other investors and learning more about real estate.

This is common in my area/Colorado in general especially the ski towns that still allow short term rentals.
