Assuming it sells for around $4.1 or so, it would be difficult/impossible to duplicate that home even at todays' depressed building prices. The back yard is nice, it has decent views - overall I think it's a nice home although the landscaping is completely overgrown and needs to be ripped out and redone just like a lot of other homes in Shady. Although it's a corner lot, Boulder View and Black Falcon don't see a lot of traffic now (except construction traffic) and once all of the homes are built out there will be almost no traffic.
If I were in the market today I would give it serious consideration, especially since the building process at Shady is such a pain in the arse. You have to figure about 3 years minimum to build a home from the time you buy a lot, then you get to deal with the architectural committee sending you nastygrams every other week, the "roving patrol" citing you for one thing or another, and the list goes on. You're always about 1 letter away from a lawsuit for one thing or another. There is definitely something to be said for just buying a home and moving in.
