Unless your Realtor builds it into the purchase agreement, your prorations will be based on the rate as currently billed. However, If you have escrows set up (your taxes and insurance are included in your payment), your lender may base the escrows on the homesteaded rate. In some cases, the payment would be significantly affected. If you feel that even the homestead rate is too high, you may go before the "tax tribunal" which allows homeowners to dispute their taxable values. You would need to check with the municipality for the appropriate date. If you are asking for concessions and the seller waives the prorations, please consult your lender as some will deduct the portion of taxes waived from the total concessions.
When you submit your offer, you can request in your purchase agreement that the seller pay all taxes billed in the current calendar year. Your lender is still going to create a reserve to pay your taxes based on the non-homestead amount.
If this home is a foreclosure or REO, pay close attention to the addendums that you will be required to sign, as they can negate any terms in the purchase agreement that you submit- including how the taxes will be pro-rated!

Shirley is correct, on both accounts. A good, creative Agent has options available as relates to drafting the offer to help offset those taxes for you for the next year until they are reassessed...
Best of luck.

Unfortunately, you will have to wait until next year. Assessments (and reassessments) are done once a year in the spring. At the closing for purchase of the property you will be given a form by which you claim your homestead tax status. You will file the form at the township in which the house is located. That will trigger the homestead tax rate at the next assessment period.
There are a number of ways your offer can be written, however, to try and defray the higher cost of the taxes. Your agent should be able to help you out when writing the offer.
Best of luck to you! Purchasing a home is an exciting adventure.
