I am looking to invest in small multi-unit housing properties, but would like to know more about long-term sales price trends in the region of interest. I am new to real estate investing.
Are there any free or inexpensive places to find this information? I'm particularly interested in being able to identify trends for close comparables in a given ZIP, e.g., all 2-unit buildings with garages in ZIP 12345.
Should I just make friends with someone who has access to MLS, or are there better ways?
