Sims who have enough money can invest their money to become a partner or buy out the property to earn more money. The cost of partnership is §2,000, while the cost of ownership is §20,000. Sims can collect money from the vault for §1,000 (partnered) or §1,500 (owner) every week. While the price of partnership is considerably cheap, the price of ownership is very expensive, costing tenfold more than partnership. On the other hand, the return of investment is very low. Owning the Vault of Antiquity is practically not beneficial.
