Query: You Can Purchase Tax Lien Certificates

These certificates pay a guaranteed rate of interest which varies, but can be about 5 or 6 times the interest rate of money in the bank. In additon, there can be a bonus at the end of the certificate time (sometimes 2 years). If the lien is not paid off with interest and fees the governmental taxing authority will sell the lien to you and then you own the property because you paid the taxes on the property.
