So looking at it, it appears that it is pending at that price and that Zillow felt that it was worth $387,000. Trulia is reflecting the $350, 000 price.
Remember Zillow bases it on past sales and Trulia tries to project the price base on the trend. (Or so that is what it appears to me.)
But neither Trulia or Zillow actually looks at the property and the actual value can swing by $100,000 or more base on condition.
I would say that cutting the price by $10.000 would be enough to sell a home that has had a death in it. The value seems to be more than $30,000 less.
So that is too much of a cut for there being a death in property. It may be reasonable it you take into account the condition.
Of course it is hard to say having not seen the property.
