Just want to clarify what Ute said about Zillow vs. what you are looking for -
What Zillow has are recent sales information, whether it is active or sold (so, in your case, if the house is active and the data is entered onto Zillow, it should be the list price. So, since the house you are interested in is currently on the market, the price on Zillow should be the list price.
However, for other properties that are NOT recently sold, the price listed on Zillow is the estiamted value of the house only by taking data from tax records, appraised value and whatever calculation methods they use to come up with the Zesimated value which can be quite incorrect.
For your specific question; Bridgette's answer is probably the better one to go with. - or call your Realtor.
