Thanks again for the replies. I went on a camping trip this weekend at a family ranch and it really reinforced the idea of getting out of the city. It also reminded me that when you don't have sod things get dusty real fast, but I can cope with that
What will I do with the land? Enjoy it, really. I'm not looking to buy a ranch or a farm. At most I might do a large vegetable patch. I love the idea of being able to step out my door and being surrounded by the natural scenery, to be able to stargaze in my own back yard without worrying about city lights, look out a window without seeing into the neighbor's house, set up an archery range in my own yard... and for me, the isolation is part of the reason I want to move from the city. I have enough friends and family in the area that I can find company if I need it, but I love the idea of having my home as a retreat.
I have a choice between something in the Rocky Mountains or something on the front range/plains. To get something affordable in the mountains I'd have to go in a bit since the closest properties are really expensive but prices drop quickly once you're into the mountain range (then go up when you get close to the resorts). Most of the lots I've seen listed are on a pretty good slope but even the cheap ones have some great views. Driving on the side roads in the mountains can be slow but the scenery compensates (unless I'm running late, of course!)
Alternatively, there's a wide variety of options at lower altitude, from planned neighborhoods with large yards to properties that used to be small farms or ranches, located just outside of the suburbs or several miles out of town. Many are in or just outside of a small town that would have banks, grocery, etc, some are in relatively modern developments while others aren't really that old but still have a frontier feel to them, and so on.
I have a while to figure out what it is I want, but once I have the down payment saved I want to know what I'm looking for.
