Is a co-op technically an investment or not?

[Jackie Mcmorrow]

Hi BiggerPockets Family,

I’m trying to start my real estate investment journey through the purchase of my primary residence, with the intention of selling it in less than 5 years. I was open to condos and co-ops but after more research am stuck. 
Are co-ops even technically an investment (considering you don’t own the actual space)? Should only look at condos if I really want a taste for the investment world? (Late this year/ early next I want to start building a portfolio of out of state, long term rental properties). Can anyone share their thoughts? 

(Where I live/ work, I can only afford an apartment so don’t have the opportunity to house hack with a multi family)

Thanks in advance! 
Jackie
