2002 or 2020 - sometimes there are typos? this assumes there was no estate return. there's no way to know if the property taxes for 2002 would give a proper valuation. in some places they are supposed to be FMV for others, it's some fraction. another way is to contact a realtor familiar with property in that area to get a valuation. when you sell, and 1099-S are issued, see that two are issued. one for each of you for 50% of the proceeds.
