I believe I heard that too. And I'm sure the value has risen.
Just for shits and giggles and because I'm having a boring morning, it was listed at $16,975,000 when they bought it. I believe it actually sold for between 14-16m. It was sold 'off listings' so the sale price isn't public. We'll figure they did the US normal of 20% down and a 30yr 'conventional' mortgage. That's a loan of $12,800,000. 2020 average interest in 2020 was around 3%. If they've owned the house for 6 years that 'amortizes' out to having paid just $2,304,000 on the principal leaving an outstanding balance of $10,496,000m.
Zillow lists current value at $23.11M - $41.29M, however I've found that Zillow overinflates values. So, we'll take the lower end and figure a current value of 25m. Less the outstanding loan, that would give them $14.5m or £10.84m from the sale of Montecito to purchase a new place in the UK. T
It's said that M must have at least 9 bedrooms and obviously they're going to want 'acreage'. Will ~ £11m buy her what she wants in the location she wants it? I have no idea what mansions in the 'chi chi' area of the Cotswolds are going for these days. And having no idea how UK home loans work, I wonder what amount they could borrow with an £11m down payment.
I know. Wouldn't we all love to have the problem of 'only' having £10-11m 'cash' with which to do our house hunting. Sigh. How the 'other half' lives, eh?
