There are a pair of high end properties that were on the market last year. Neither property (863 Mill Creek Road & 859 Mill Creek) sold. Both properties were listed individually for around $1.9M. The MLS shows them both as expired listings.
The home that you saw is 863 Mill Creek. It's original price is shown as $1,998,000. It was built in 1933 and has almost 3000 sq. feet on 8 acres. It also has a guest cabin and an art studio. It's definitely a fabulous mountain home.
The other home is a little small, with about 1600 square on a 3 acre lot. It was built in 1956.
Mill Creek is a great area. I don't know if you got a chance to go up the road to Mill Creek Park, but there are another 35 or so homes about 3 miles from I70. Most are on the creek, and prices run from about $200K to $325K (for what's on the market now).
I don't think many people know about Mill Creek. And it's only about 5 minutes to the nearest Starbucks!
I'm glad to help if you have any other questions. My folks owned a home up that way for about 30 years, so I know the area well.
