Strategy around substantially low listing price

[Pandu Chimata]

Folks, I saw one house listed at least 30% below the market. I understand sellers list the marker 5 to 10% below the market to get more offers on the table. 

What could be the motive to list the house that low? 

Only to attract more buyers.. is the house substantially in a bad shape? They did not post the inside pictures of the house though they did post the outside pictures. 

Any thoughts?
