I did one some years ago. A customer wanted a property option embedded in a contract to be valued by Black-Scholes.Customer wanted it, we did it. With some adjustments to parameters and formula. I wasn't too comfortable with it, but since they only neded it for accounting reasons...The problem is, that, in my opinion, you can't assume any Brownian Walk in Property-Prices. They are far mor dominated by macro-economic effects and trends than something like equity. As far as I'm concerned, I wouldn't touch any new derivatives in markets where everybody agrees on the fact that you have got a bubble in place.Exept of course if I am absolutely sure of what I'm doing.
