Did you ask the listing agent why it's listed? Maybe it's a couple divorcing and one party wants to sell and the other doesn't? Or if there are 2 or more owners, maybe 1 wants to sell and the other(s) doesn't? It may be listed just to 'appease' one of the owners who wants to sell? Is it a standard sale at the list price but the list price is over market price? If this is the case, and it should really be a short sale, maybe the seller(s) doesn't really want to sell but has to? (Has an NOD been filed?) Ask the listing agent and if they won't give you an answer, contact their Broker. However, if the seller(s) has advised them not to divulge personal information, they may not be able to answer your question.
Sometimes, it is a divorce and "exes to be" are competing in a "who outdoes the other in badness" contest...Had a situation when the wife left, and the husband would not do anything at all to sell - just to hurt her credit (and his too - but he didn't care about that).
In other cases, sellers changed their mind (got inheritance, transfer to another state didn't materialize, got a raise...). I had sellers who got full asking price offer cash, and would not sell - their reasoning was that if they sold so fast and so well, they should wait a year or too and they would sell for more...
Good luck with these sellers!

Again, I'm not an investigator to think about all 'why's'. It is offered for sale. My client and I wasted my time, all those other agents and their clients wasted time. At least add to private remark the explanation, so we know what to expect~ do I ask too much?
