How do I find if a property has liens against it?

[Maria Krothe]

I am doing my very first deals - 2 short sales. I'm not sure if these deals will go through - I'm just in the beginning process. But, I would like to know if there are liens on the property without paying a title company. Is there a way to do that online? I have checked the prothonotary's office online, and don't find anything there. Any advice?
Thanks!
