@Christopher McConnellThe entire process of foreclosure, adverse possession, tax sale, tax lien sale, tax deed sale, etc. is state specific and very often county specific.Any generalization is going to be incorrect for a large number of cases.If someone wants to begin investing, or speculating in tax liens for instance, they will have to learn the laws governing such for each state they’re interested in, and the rules, regulations and procedures for each county they’re interested in in that particular state (s).

Either it can't locate the person or some of the numbers are incorrect.

A lot of folks complete it incorrectly so free isn't always the best.

@Chester Transo You are looking at cap rates incorrectly. 

Real estate is often seen by folks as the solution to their financial woes, but that is incorrect.  

Most people think they will be in a lower tax bracket in the future because they plan to downgrade their lifestyle... this is again incorrect money myths that are so prevalent.By taking you money out early you will incur a 10% penalty but if you understand how you can easily get 20-30%+ returns in real estate a year that 10% penalty is nothing.

Unfortunately many reps who work for IRA custodians are uneducated, inexperienced and often mislead their clients by telling them incorrect information... 

@Peter Morgan I would hate to make a formal recommendation because I am not too familiar with what moves in your market (and who knows I could be super incorrect!).

@Antonio Estrada  Zillow has a Ton of incorrect/irrelevant information.Find an agent....Is the house actually for sale?  

They often assume (incorrectly, in my opinion) that you will need less annual income in retirement than you need today.
