Many students ask how we research and read tax lien lists and what all the numbers mean?  Also many students wonder why there are tax lien lists available from a year that has already past.  The one thing that you want to understand is that it takes a year for a tax lien to be delinquent.  So if you are looking at a list from 2009 or 2010 and it is now 2011 and you are wondering why the list isn't a current list, then let us explain the process a little bit more.  First of all, if you are in the year 2011 then you will be working from a list of 2010 or 2009 depending on the state.  Arizona is a state that waits for the taxes to be delinquent for two years before they sell a tax lien at an auction.  Therefore, if you have a tax lien from the year 2009 it will be sold at an auction in 2011. Let's take Florida for an example.  If you have a tax lien from the year 2010 then it won't be sold until the first week of June in 2011.  So the most current listings in Florida are currently from the year 2009.  The next listings coming up will be in June of 2011 and the over the counter listings won't be until a couple of weeks later or the end of June 2011. Next, when considering a list and you look at a parcel number and it doesn't have an address with it, then you will want to go to that county's assessor's website, the county's property appraiser's website, or the county's appraisal district, depending on what state you are in, to do further research on the property.  Oftentimes, the list will only show basic appraisal, owner, and lien/deed information, but may or may not list all property information.  Most of the time, this information is easily accessible through the county websites.  Once you go to that county's website for the property appraisal then you will be able to plug the parcel number in and get the information you're looking for.  This information will include the property address and usually it will break down the difference of land value and improvement value, helping you to make a good decision on your tax lien purchasing. As for the lists on our website, we typically just leave the lists from past years on the site.  Don't be offended.
