Typically property ownership does not by itself cause you to be a resident of the state where you own property, nor does lack of owning property disallow you from being a resident. The main factors that dictate residence are more related to how you conduct your life. Things like amount of time you are spending per year in a location (and how long overall), in what location are your autos registered/insured, where are you registered to vote, etc. Another factor that might come into play in some discussions is whether you intend to relocate back to Colorado, making your time in Nevada "temporary".
Here's a link to some Nevada residency information: https://www.leg.state.nv.us/division/research/publications/factsheets/residency.pdf
One additional note: if you are renting out your home in Colorado, it is possible that you would need to file a Colorado non-resident return to report the rental income. I'm not sure about Colorado, but based on personal experience, I have to do this with a Michigan property.
