The owner of the riad we like still doesn't appear able to clarify whether it is titled or not, despite owning it for 2 years. Sounds like its not titled! Notwithstanding this, he's trying to put me under pressure to make an offer, having bought it at the peak of the market and not sorted the title, he still thinks he can find a mug to buy it for a premium when the market has dropped 30%. Well, at least he's an optimist!
Spoke to Grant again today on Skype, who has confirmed my fears and given me confidence that we can get more for our money elsewhere. The search continues.
Emailed Simon at Riad Laksiba, who responded very helpfully and having worked with Grant to find and renovate Riad Laksiba, is very happy to recommend him. Looks like we might be staying there in December!
