thanks for asking
My strategy in buying domains is buying domains that I think might be brandable, cool, easy to remember, some with typo (letter switch) like peircing (not typos like jotel for hotel), i put my domains into groups and start marketing and wait for a buyer, if i sold one that covers the reg fees for the whole group of domains then im fine, i always try to sell the worst domain in the group first, then after that every sale is a profit, this way worked for me veeeeery well in the .coms and . nets.
As for .ae its a different story, you have to be selective and very aware of the business environment and culture of the uae, one right sale and you cover all you costs and make at least 200 times what you paid for the reg fees
horse.ae was sold for 6 million dirhams (approx. 1.6$ million)
so i will use the same policy with the .uk and hopefully it works out,
if i didn't then I will consider what i paid is the cost of learning
