There was a lawsuit here a few years ago over an incorrect square footage and acreage in the MLS listing. Ever since then you have to look that information up in the tax records.
Additionaly, our wonderful MLS hides listed date and DOM for active listings.
Our MLS as well requires all of the info in the original post, and is actually fairly accurate.
As far as no listing date or DOM, that would suck. Ours even show Cumulative DOM once it has gone under contract.
