Troubleshooting: How much and when do the buildings payout?

I thought I would create an on-going guide of how regular buildings payout so you know when to go into your game when building up your $ stash for new districts, events, blocks, etc.

District 6: The Civic Centre (Unlocking Brian and Dr. Hartman)

I have created a basic walkthrough for District 6 so you can see what quests will need to be completed, once I have finished the individual, longer versions of each quest, a link will be added.
