Seasonal felicitations my thrifty comrades...
I bought, for £37K, a 3rd floor studio in the 'England cluster' section of 'International city', some 3 years ago. I enjoy at least 11% yield (unfurnished). There is a glut of overt, 'executive' type property but the other end of the market, for teachers (not expat) and medical staff, there remains little choice. So, my only conclusion is:
If you have bought in Dubai and it's around the £35k mark, you'll be alright. Rental demand is high.
