It's a beautifully fine-tuned machine when it starts working in concert.So the real question we need to answer for ourselves is:Do we want to be and stay stuck with the immense repeat time investment and painful learning curve, which no software alone will solve for us, or do we want to focus on growing our team (with the appropriate skills) and business by doing what we do best (and outsource the rest):Buy & Sell real estate.Food for thought ;-)On a side note, I'd be interested in what strategy and process exactly was applied by your marketing team that yielded zero results.
