I heard about it on the radio because there's another company doing it also. I also was quite interested but would be interested to see how they calculate the estimated return. Also interested to know what you do if you want to sell it on and what is the potential for capital appreciation on the room. Do you get any additional information? I'm going to follow up on it to-morrow.
By the way, this can also be used as part of a pension plan which is interesting also (however, you will require about 100k in your pension).
