I am a real estate agent in NJ and I only deal with commercial.I can tell you that a commercial investor is a totally different machine than a residential (1-4 units) investor.1-4 unit residential properties take alot more effort(generally) to run and maintain but the investor has the opportunity to be alot more involved in their property than a commercial investor does, if that is what they want.A commercial investor generally does not want to be so involved in their property unless they are running a management company which handles many properties or unless they are an owner/user which has surplus space which is rented out.I suppose it depends on how personal you take your REI and whether you can deal with not being able to be involved in your properties everyday mechanics.
