When I heard how much her mortgage payments were, I was pretty surprised. I know someone buying a $750,000 house. If I take their payments and multiply it out to what Mischa's house is worth, Mischa's payments are much higher per $100,000. Maybe she got a shorter loan period, or maybe her interest rate is higher due to the risky nature of her career.
At any rate, is her house really that close to the construction next to it? If so, I would think she'd rather have more seclusion and less house size. That is a pretty freakin huge house though. Hope she isn't in the path of any wildfires or mudslides.
