While designing any website it is very important to know their audiences and to predict their expectations and requirements. I am sure your client will be expecting 2 category of visitors/targeted audiences - 1. People who want to buy flats or rented houses, land etc. The second one who just want to invest their money in this sector.
Lets think these 2 different people will be having what sort of requirements -
The person who wants to purchase/rent a property will have concerns about - look, location, cost are main parameters
The second type will be searching for those who are reputed, having good growth rate, are professional, trusted, different projects will be parameters to decide should they invest or not.
