Junior Tax Liens

[Crystal Harris]

In February 2024, I purchased a tax lien from Nassau County NY. A few months later, I received a notice to redeem letter from a 2019 tax lien holder. The owner has until November 29 2024 to pay the 2019 tax bill or the tax lien holder can start the foreclosure process. It wasn't until then that I realized that I purchased a junior tax lien. 

Would my tax lien be extinguished if the homeowner fail to pay?

Is there anything I can do to protect my investment?
