Real Estate tax liens

Nebraska- I am behind in my real estate taxes for the last few years, someone has purchased the tax in a Certificate of Tax Sale. We received a letter stating that after the expiration of three months from the date of service of notice which I believe is the letter we just received from a lawyers office that this person can apply to the treasurer's office for a deed to our property. My question is if we go the treasurer's office and pay the back taxes can we still loose our house?

You have to pay the holder of the lien--but if he is paid off then you will be fine normally.
