I feel like a parking garage markets itself. Are we trying specifically to market the garage or market the property with this feature attribute?
Plus, as Eric Cato is pointing out, there are so many variables to consider. What does it cost? Where else would you park? What are your competitors doing? Are you the only community with this option? Who's the target; current tenants or is this to drive new tenants? Is it multi-level? It it also gated?
