Laundry is set apart from other investment opportunities by a singular advantage -- laundromats are a cash business. This means that all payments are up-front and on the spot, with no accounts receivable issues because owners don't have to wait for customers to pay their bill. Plus, a coin-operated laundromat is the rare business venture that is virtually recession proof. Laundry is a necessity of life, and generally more protected from economic downturns than other businesses.

An investment in a coin laundry averages about 30 percent return on investment, and nearly 100 percent of laundries are successful after five years. The income received from owning and operating a laundromat is also more consistent from year-to-year, and offers greater control against employee theft because the laundromat owner controls the money collection.

Whether you are looking for a full-time investment opportunity, a way to enhance retirement money or to earn an extra income, owning and operating a laundromat is a great opportunity with a strong return on investment.
