Has anyone invested in property tax liens? It seems like an interesting model - low returns most of the time with an option to make a killing once in a while (via foreclosure). Returns in towns like Newark, Camden and Trenton (NJ) seem to be around 15-18% from talking to people in lien auctions. Texas (from what I have heard) allows for as high as 25% interest to be charged to home owners who are late on payments. Other than the administrative hassle of paperwork not sure I see any other major issue. Would be curious to hear if anyone has explored / invested in these before ,or, just general thoughts on why this may / may not be the best use of time. Thanks.
