Frequently Asked Questions

How do I decide whether it is better to lease or buy a commercial property for my business?

The right choice depends primarily on how long you plan to occupy the space and how much equity you have available. Leasing offers more flexibility for shorter time horizons, while buying can make sense if you plan to stay long-term and have enough equity to invest. Brian Clapp and Spencer Clapp can help you weigh these trade-offs for your specific situation. Many companies only compare a rent payment to a mortgage payment, but the occupancy timeline matters just as much.

When should a growing business reconsider leasing vs. buying its space?

A good rule of thumb is to revisit the decision around the three and a half to four year mark of a lease. At that point, it’s worth reevaluating the company’s space needs: staying in the current footprint, expanding into more space if business is growing, shrinking the footprint if finances are tight, or purchasing if enough equity has built up to make ownership the stronger option. Brian Clapp and Spencer Clapp can help walk you through that decision at any stage.

How do I sell an office, medical, or flex property in South King County?
