I was wondering if there is a way to search the public records to find a list of properties with tax liens (federal, state, and/or county) attached. For instance, when someone defaults on a federal tax debt, the IRS may file a lien on the defaulted amount. These liens are public records, but how do you view them? Are there lists I would have to buy?

Is there a particular database I could search? I've tried looking at the web page for the LA County Tax Assessor, but came up with little to no usable info (unless I wanted to pay my tax). 

My thought--and I'm sure many have thought of the same thing already--is that people with large tax liens would likely be more likely to sell their homes in a shorter amount of time. 

Do you have any previous forum posts or directions you could provide?
