$2,000,000:

Remove old units:
Hold [Shift] when placing a new unit to automatically remove the old unit.

Extra money:
Use the magnifying glass to click on the condo that is marked "For Sale". A message similar to "The conditions are terrible" will appear.. Click on the current price, and lower it to $4,000. The comments will disappear, but do not exit. Immediately after the price has been lowered, increase it to $20,000. Note: This trick can also be used with other rooms, such as offices, hotel rooms, and the small retail shops.

Build an elevator in the middle of your tower, then stretch it to the B3
