Sersiously considering building an apartment building. What do I need to know?

[Manuel Sarabia]

I know what it would cost me just to build the dwelling. But I need to know where to start for the land purchase, fees, any inspections/permits/fees from the city in order to build, etc. I'm not sure if it's possible but I would like to arrive at an accurate number for the cost to build with everything included.

Apartments are almost non existent in the resale market and I am willing to buy the lot and build myself if I'm making a good return.
