Quote from @Isuf Aruci: i live in the NY area and would love to build a house or a mid apartment building. but the land search is very very difficult. also lets say i found the land, where would i get information and see if its buildable, also how do you calculate a land to see if its worth building or not.   

Its called a "look ahead schedule".The key to building a good schedule is knowing the information and the sequence the work must take place in.

The long-term strategy involves building equity, saving, considering taxes, and leveraging rental income for investments.
