It could be the start of just many. Large transactions such as buying a house are ideal to be transacted in cryptocurrencies. The fees involved will be much better with bitcoin than with fiat.
If a major UK estate agent such as foxtons were to start accepting bitcoin that would be a big breakthrough.
Estate agents like foxtons are just the middle men. The actual transaction to purchase a house is handled by lawyers, between the vendor and the buyer. Obviously new house builders like Hagan Homes are vendors, so they can enable bitcoin. But I doubt foxtons will be able to persuade the ordinary sellers on their books to accept bitcoin.
Ahh I see. That would only be considered then on new builds, how could the adoption be increases for sales of homes which are already built and being sold from one individual to another. I guess the lawyers would be the ones to make the decision, if they somehow facilitated it so that the BTC/GBP were converted and then buyer/seller receive/pay in GBP/BTC depending on which side of it they are.
