Dear Giorgio,
Selling and renting depends on the customer demand. You can sell or rent it through bayut.com by posting your property listing which would be visible in the "buy" or "rent" section.
Please contact any reliable agent to know about the price per sq ft of that location as prices do vary according to area and location. Here is one apartment for sale which can give you a rough idea about the price per sq ft:
Considering the current market climate, it would be easy to rent out but quite a task to sell it.
As mentioned by Avelina, it depends on the market condition, supply and demand. At the moment supply is high and demand is low and we need a shift towards higher demand and lower supply. When that happens it will be easy to sell the apartment.
You can contact many agents from the agents section within bayut.com and they can help you to sell or rent out the place.
Well Ms. Avelina has provided you much of the useful details. I would suggest that if you are not in a hurry to sell your property then it would be better to rent out your property now and sell it when the market conditions become favorable.
Doing this you can sell your property at higher price and until then you will be able to get some money in the form of rent as well.
