From searching online I haven't got an answer the actual process if I can remove it, every blog says talk to a lawyer, it survives tax deed and purchaser will be liable, but it doesn't answer if I buy whats the process to follow and if its even possible to clear title other than being responsible for the amount.the property is worth around $800-900k, Auction starts around $80k, given the hassles involved, I wanted to know how much it would cost in addition to tax deed purchase to get a clean title.

I have done several courses online including the real estate license course which I had done from https://grel.org/.

It depends on your local rules but splitting a parcel can be a major pain and the locality might not even allow it due to zoning or setbacks or lot size restrictions.
