Landmark Advisory released a report today showing apartment rental rate declines of between 1.3 and 7.7 per cent in some of the most well-known neighbourhoods of Dubai. Villa rates have remained relatively stable.

Here's an excerpt:

"Turning to residential apartments, increased supply has put downward pressure on rent in many areas, including some well-established quality locations. Places such as Palm Jumeirah and Dubai Marina have seen an increase in supply following new product deliveries with lower limits; 2-beds on the Palm Jumeirah have fallen 4 percent from AED 120k to AED 115k annum while 2-beds in the Dubai Marina have fallen 6 percent from AED 90k to AED 85k per annum. This is a typical trend observed in both recently-handed over buildings and lower quality buildings."
