Tax Deed Sales, Tax Lien Certificates, Tax Sales, Tax Liens
A tax sale is the public sale of property at auction by governmental authority, due to nonpayment of property taxes.
A Tax Lien Certificate is a first lien on delinquent property that yields the holder of the certificate high interest rates. The property owner must pay back the original sum of taxes and other charges, plus interest accrued from the time the Tax Lien Certificate was issued. If the property owner fails to pay within the redemption period, the owner of the Tax Lien Certificate may be awarded an "absolute deed" for that property.
You could make money by buying properties at tax deed sales.
