It's not that hard to buy a plot in Karachi if you know the right people and you have the amount to invest. The Real Estate Consultants that I close were RedBox Estate and it was one of the best decisions ever. I discussed all the options with them and they guided me so well. Now I own almost 3 - 4 properties and I am feeling better than ever. Highly recommended to go and check out the nearest real estate consultant around you.
