All properties were sold within 90 days of death so I believe we can use the sale price of each as the step-up basis.
The sales are required to be reported. but there is no such tax law, regulation, rule, or guideline (i.e., 90 days).
Generally, the fair market value on the date of death controls and that value must be substantiated if questioned by the IRS. For real estate, there may not be much variance, if any, but mutual funds and other investments may be more volatile.
