Is it possible to buy ONLY garage?

[Justin Sofman]

Hey all, 

My investment property has a detached garage and it illicit some really great interest in renting it.  Has me thinking, is it possible to purchase only a garage from a homeowner with the purpose of renting it out?  I'd think paying all cash for one may be enough to get someone to sell it to me.

Anyone know if this is possible?  I have one agent telling me yes and another telling me no. 

Thanks!
