Do I inherit State and Federal tax liens when purchasing tax sell

[Marty Hofmann]

Last year we purchase an investment house on a big lot. Shortly after closing (online forecloser auction) we found out that we only purchased 1/2 the lot as the county only foreclosed on the one lot. The adjoining lot will sell soon at the local propery tax sell, but it has a federal lien from 2011 of $250,000 and state lien from 2010 of $11,000 on it. Our understanding is that these liens will follow the new buyer, is this correct? Is there a way for us to have these liens removed or satisfied cheaper as the property is only maybe worth $10,000. I am sure many would say run, and we are prepared for that, but currently the septic lateral lines are on this property, so found like to purchase it so that we can easily sell it down the road. We are also wondering if these tax lien would effect our credit score if we inherited them at the purchase of the property. Thanks for any help.
