A property manager is focused on property maintenance items, such as landscaping, leaks, paint, carpet, etc. They must also lease space and collect rent fees & payments. However, the property manager’s focus is usually on the “what is” rather than the “what it could be.” While an asset manager performs many of the same functions as a property manager, that’s where the similarities end. We continuously review your property’s income.
