Deed of trust covering sale of foreign immovable property

l would be grateful to Forum members for their comments on the following Deed (an anonymized version); much has happened – which I’ll share if anyone is sufficiently interested - but for the time being, rather than overload with factual information, I thought it would help if we could treat this rather like an exam question: “Discuss” (Hint as to present situation: at the outset, seller gave buyer a POA to enable buyer to conduct the matter, which the seller has revoked in the last month; buyer has not yet complied with clause 5; both are British citizens, UK resident and domiciled, although originate from outside UK):

Date 30th October 2015
(1) Seller (the Trustee)
(2) Buyer [the Beneficiary].
