Choosing a lease term isn't always as simple as it seems. The old rules of thumb -- that long-term leases are cheaper while short-term leases are flexible -- still hold true. However, given that business is changing at a faster pace than ever before, more and more companies are finding that the flexibility benefits of a short-term lease are cancelling out the savings that can be found by signing for a longer term. The ease of management that comes from commercial real estate software also supports this decision.
