Not really, it sounds like a rainy day fund - a business may be out of business (or out of the building) within ten years, but the building will be around for at least another fifty, retain its value, and provide constant income.

The laundering aspect may have a grain of truth in a way though; instead of having e.g. an investment or sale paid out (and consequently taxed), it's rerouted into buying a building. Why pay I dunno, 50% income tax to get the money right now instead of reinvesting the money and long-term earning a lot more?
