Well, here's a price tag for you
/New today, 88 Cedar Cliff Road, Riverside, $25.5 million. 1.77 acres of non-waterfront, but great views, and the house matches this price, I suppose. I knew the owner of the house that originally stood here, and I was suitably impressed when the land it sat on was sold by her estate in 2008 for $11.750. Gosh.
So, take that land value, add the cost of building this-quality house, then multiply by the COVID factor, and they’ll probably get something close to this.
