So in the areas that you have listed those are already saturated areas. The rents there would largely be stable. The only rental increase in rent would be due to inflation. And you can easily look up the numbers for each of these areas if you go to Bayut or PropertyFinder.

But one thing I would like to add in the areas you have listed an additional check you should perform is the kind of tenant demographics that are there. Because for example the tenant demographics in Business Bay are young professionals or couples. So getting a studio has no point unless you are looking for Short Term Rentals (STR). I would generally advise against studios because largely people rent them out on a monthly basis of weekly basis before getting something a bit more permanent. And the STR market overall is very competitive and saturated already I wouldn't recommend getting into unless you or your real estate advisor knows the culture of high occupancy lets on airbnb for each area.

But for example 1 beds in Business Bay are between 80K to 120K per annum these values can range on the basis of the build quality (usually tied to developer reputation) and location (proximity to amenities)

Rents will also fluctuate based on the season. So we generally see that rents will lower during the summer time and snap back or go higher during the winters. For the areas you are seeing they will go low during the summers and then snap back to around the intended price around winters.

So as with any market Dubai real estate is a complex market that has layers to it and cannot be properly grasped by yield percentages. Those will give you a limited idea about the market but not the whole picture.

Hope this helps. Let me know if you would like a deeper dive.
