You can't. The assessed price doesn't have much to do with the sale price. You can attempt to file a tax appeal once you own the home, however most tax appeals fail. You have to prove that your house is taxed unfairly compared to other similar homes. It doesn't matter what you are paying for it. What matters is this: are the taxes on this home significantly higher than other similar homes in the neighborhood? Usually it turns out that they are not, and the tax appeal is not granted.
Good luck though!

As I understand it, there is a law in New Jersey that no home can be assessed for more than the home can sell for, and that the appeals must be filed by April 1 of each year. You should definitely check out your situation with a tax attorney like Jeff Horn.
Once you own the property, reach out to tax attorneys who will be able to guide you better.
Marc is spot on as usual. If you would like a second opinion, google Jeff Horn, Toms River. He is a tax appeal attorney. His assistant (also an attorney) will provide you with an opinion as to your chances of a successful appeal. I've atttended seminars by Jeff and referred clients to him as well who were very happy.
