The vast majority of the industry just doesn’t have the vision and talent to consolidate the data sources.
Is this because the industry itself is so fragmented? If I were a realtor/broker paying fees to belong to NAR, I’d expect comprehensive, realistic data, from which I could plan my own marketing accordingly.
Also, did you mean your last sentence to read the way it does? If so, can you be more clear? (Who is “your”?)
