Walk through downtown L.A. There are signs and prices all over . Walk on broadway and 5th st then walk on 5th and main st then walk on grand ave and 7th st but just look up on buildings there are all over and pretty reasonable In live in east la so I see them all the time
I would begin with an internet search for a real estate agent in the area I am interested in. Once I selected them I would tell them what I'm looking for, the price I'm prepared to pay and let them bring the properties to me.
