Don't go riding with your realtor... When I moved to CO in 2003 the guy who sold me the house took me up riding. I should have known the Cat "Powder Special" he was riding was going to be a liability. By 11 am he was hopelessly stuck in a ravine. By 6pm I was calling search and rescue to get him and the sled out. Granted the snow was epic, the sno cat almost got stuck trying to get to him. Never rode with that guy again...
I wouldn't take advice on riding from a realtor, just my experience. After years of looking all over Colorado we settled in the SW part of the state. We are usually the only group in the parking lot to go riding on the weekends. We get epic snow and the weather is mild. I am sitting here, at home, looking right at the mountains we ride, only a 15 mile drive to the parking lot.
There are precious few places you can have a home/cabin and ride in/out of the choice terrain. I would give up that part of the plan as it will limit you. This isn't MN where that works from so many places. Being willing to drive up from the valleys opens up a lot more riding choices and makes "living" much much easier than a remote cabin. Unless you like hauling water and paying to keep something plowed out all winter, I would give up on the ride in/out plan.
I can definitely hook you up with a good realtor down here but he doesn't know a thing about sledding LOL.
