I had a neighbor in Aspen who put his home theater under his front attached double garage. Cost was $50K back in 2011. Make it a tripple, add the lift, plus inflation... probably $150K now.
This house has me asking so many questions. Like why dig a pit to force a walkout and then fill that pit with a hot tub that your neighbor can see?
Lots of money spent to make the house fit desire instead of finding the right lot. It also doesn't front or back onto the park.
A lot of money wasted that you won't get back because of location and lot. Silly.
