Drunkle:
None of the DOM info or relist info constitutes required disclosures drunkle. If you feel it is important to your goals and you are working with an agent they will certainly tell you.
I think DOM are pertinent for low ball strategies. Long Dom is a red flag too. It could be possible that the house was rejected by previous buyers, so you would want to know if it had fallen out of escrow a couple of times and if so why. If it had fallen out of escrow because of material defects or title issues or anything like that those items all would neccesitate disclosure. Excessive DOM could just mean that the thing is overpriced.
What are your reasons for wanting to know DOM and relist info? I am just curious.
