I am sure they changed it to all cash because of all the interest it is getting. I suspect it is valued under market. I would run comps in the area to see the value. I suspect it is under value as that is what people that sell cheap want..... quick cash.

Ask your Real Estate agent to run some comparables in the area and make an offer based on current market conditions.
