For those who don't know, I spend my weekdays writing about real estate. House prices in Holland. Property sales in Spain. Exchange rates in Estonia. All that jazz. If by jazz, you mean property. And definitely not film.

But every now and then, there's a little bit of overlap between housing and cinema - and not just Home Alone. 

Take Wayne Manor, for example. 11 bedrooms. 7 bathrooms. 1 Batcave. How much would Bruce Wayne's home cost if it really existed - and it was up for sale? Some bored (and brilliant) soul's actually worked it out.

Taking Chicago as a stand-in for Gotham, they combined Wayne Manor's size and the city's average price per square feet of real estate. Simple, really. But as a fully paid-up property AND film geek, I rather like the fake listing they've created:

So that's official, then. Wayne Manor costs $32.1 million. I'll just sell my horde of imaginary unicorns and we'll all move in next week, OK?

... And that's enough property talk for now. Normal film service to resume from tomorrow. If you can't wait for then, read our Dark Knight Rises film review.
