There is technically no date of inheritance ( no stepped up basis) because the property was sold prior to the passing of the life tenant. You will most likely need professional guidance with respect to this scenario.
The sales proceeds will (should) be divided between the life tenant and the remaindermen according to the IRS actuarial tables.
See https://www.irs.gov/retirement-plans/actuarial-tables
Further, remaindermen are not be eligible for the Section 121 home sale exclusion. With respect to the remaindermen's basis in the property for figuring a gain, that would be the same as the donor's adjusted basis (since this was a gift) except the value of the life estate at the time of the gift has to be taken into consideration.
Again, you (and the life tenant) should seek professional guidance with regard to this matter.
