Yes of course you can still sell it. The title agent will obtain a tax certificate providing the exact amount of delinquent property taxes owing. That amount will be deducted from your gross closing proceeds.
As Mr. Lauten correctly stated, you should have no problem selling the property. The unpaid real estate taxes will be withheld by the title company at closing, and paid to the tax authorities. There may be a complication however if the proceeds are insufficient to pay the taxes. Then, in order to close, you will have to pay out of your pocket (unless you can persuade the buyer to pay them) any taxes due that the proceeds are insufficient to cover.
I agree with my colleagues. I would add that, if you sell the property without going through a title agent the property tax liens will survive so you need to disclose the lens and have the buyer acknowledge he is taking the property subject to the existing tax liens.
