Property type - specialty

[Carol Lam]

I  found a rental property combo with duplexes, single family and multifamily.  Under each property type, it says specialty.  Based on my google search, specialty property type is any property that's not an office, retail or industrial.  So it is normal that it doesn't specify residential as property type?  I just want to make sure.  Thank you.  (You can see I am extremely new to the real estate industry)
