Under Contract on Zillow - Fall out rate?

[Jonah Kolsrud]

Hey everyone,

I am hunting for my 1st house hack in Charleston, SC and have noticed some properties I am interested in that are under contract when I look at them on Zillow. I am wondering if there is a way to tell how long they have been under contract and if anyone has had luck following up on these aging properties?

For example, there is a property that has been on Zillow 150+ days and I am wondering if there is an opportunity to chat with the agent should this fall out. 

Thanks in advance!
