Now that you have a list, one by one go through each of them and think about what makes it stand out.
Such as location? May be it is closer to a business hub and people are visiting that area frequently. Or it is in the vicinity of an airport and development in the area is happening at a faster rate.
Developers i.e. who is developing the project? Find out their previous projects, their level of completion and success.
Any political affiliation? etc.
