First of all, awesome post about your city!

Love the spreadsheets you are using (do you use excel here?)!
I think i need to do the same! Do you enter every price manually?

Keep up what you are doing and you will reach your goal very fast!
Do you consider additional investment or do you wanna reach the 10000 Sim Income with compounding of profits?

I think I need to start doing updates on my city myself, since i started using Hive since yesterday! :D

Cheers!
