No investment is 100% safe. Having said that we are seeing a return to investment in the credit worthiness of the tenant along side all of the typical desirable attributes of commercial real estate (like location, parking, access, age, sise, etc).
I'd say looking at a NNN investment, single tenant, with a long lease in place to a credit tenant is reasonably safe. However, recently many of those top notch credit tenants are going back to their landlords asking for rent reductions or else? I believe Starbucks did exactly that with ALL of their locations.
