Investment

Investments are another way your Sim will be able to earn money over the course of the game. It comprises of Partnerships and Ownership. Both of which will put big holes in your Sims wallet but, overtime, will pay for themselves.

You must invest in Partnership first before eligible for Ownership. So, Total Cost of Ownership includes both Cost of Partnership and Cost of Ownership.

Once you have partnered (Become a Partner) or become an owner (Buy out Property) a Partner's Deed or Owner's Deed will be moved into your Sims inventory.

Although you may own the building in which your Sim works the deed will have no effect on your Sim's career.

Deeds can be transferred between Sims of the same family at anytime (by dragging them out of a Sim's backpack into another Sim), and are automatically transferred to a relative when a Sim dies.

Profits earned through investment become available at 9:00am each Monday and are not automatically paid.

They have to be collected from their respective locations hence traveling will be needed.

(1) ROI: Return on Investment = Weekly Earning of Partnership / Cost of Partnership  (higher is better) (2) payoff = Cost of Partnership / weekly earning   (lower is better)

(3) Marginal ROI = (Weekly Earning of Ownership - Weekly Earning of Partnership) / Cost of Ownership  (higher is better)

(4) Total ROI = Weekly Earning of Ownership / (Cost of Partnership+ Cost of Ownership)   (higher is better) (5) payoff total = Total cost / weekly earning  (lower is better)
