What Parameters Should Be Considered in Luxury Housing Pricing?

Our focus area is our sales and rental services of new building flats, plaza offices and shops in the Gayrettepe region of Beşiktaş district.
During the week, we had a phone conversation with the property owner living in İş Bankası Blocks.
He asked how much his flat in İş Bankası Blocks would cost if he were considering selling it.
I informed him about the price levels of the properties in the area that were advertised and not sold.
I mentioned the types of real estate in demand and their price levels.
In addition, I presented Gayrettepe with a comparison of the general demand with other regions of Beşiktaş.
Apart from these, I made a brief analysis of the basic indicators in the general financial markets and conveyed my expectations for the coming period.
Finally, I conveyed my predictions for the future of Gayrettepe.
Real estate profession is a professional profession with a scientific background. 
Only experts can produce value.
