I do not trust Diverse Solutions. A few years ago I was going to use their WordPress plugin which was advertised on their site as providing recently sold data in addition to active real estate listings. When I tried to confirm this with the sales rep he informed me that sold data was not provided. I pointed out that the site clearly stated that sold data was included. I was told that it was too expensive for them to provide. I checked their site a few months later and they were still advertising sold data for the MLS in question.
