@Melanie Collins, my wife and I are considering selling to purchase two properties and make one of the two our primary for the next year. The the other option is a duplex, if we can find one with enough sq ft. You mentioned potentially investing in another market. That is a longer term goal for us as well, just cutting our teeth in our own backyard, as recommended a lot by others more experience than us. As @Stuart Grazier said, sounds like you have "many options!"
Ultimately, we are leaning towards a sale to extract the equity and invest in two properties outside of Denver.
A few people mentioned cash out refi, but is that still a viable option with the rates increasing? Maybe meaning for BRRRR, or flips... We thought about a cash out refi, but looking closer, we would be using funds for down payments, so it would just increase our rate and reduce the amount of cash we would have access to for our purchases.
I'll be interested to hear which way you go. Good luck!
