Hi Carrie,
Looks like you already got a lot of good advice from other replies. I think other factors to consider is where you want to live long term and time frame of when you want to be able to walk away from a traditional job. Something to consider is to start buying houses in places you would like to possibly live one day. If your income allows you to make up negative cash flow for a season, you could potentially buy in a place like San Diego or Vegas or any growing city that will have reasonably moderate appreciation over time in a city you enjoy.
If you know you want to stay in CO, you could look in markets with lower price points just to start collecting properties and at least you have options. You could sell a few years down the road to buy another primary, you could hold for cash flow, 1031 into multifamily, etc. Nothing wrong with buying a lower priced house which cash flows.
I also live in an expensive market so I've chosen the long distance investing strategy with long term rentals. Sounds like you are in a good position so you have options. Good luck!
