Why does this deal sound fishy?

[Pedro Bartolomei]

Found a listing on redfin for 225k . Its a legal 2 family home that needs a complete gut . Seller bought it 150 k 6 months ago to flip it but according to agent the seller wants to move on to bigger and better deals and wants to get rid of it . Arv on the home is 450 k so the seller is potentially walking away from a 150k profit . Seems fishy to me . Any thoughts?
