It’s not the newest, nicest, biggest in MM, and not even in a great area of MM. If the best would land around $325K, then this should land around $300K, making the price-to-rent ratio 10.6 (300/(2.35*12)), which seems way too low.
The historical norm for the price-to-rent ratio in SD, before the recent bubble, was around 16 (which makes this home $450K).
