a) yes the WA house was sold on 7/22/2021, almost 2 months after we became permanent WA residents. If I understand correctly, income earned from jobs, pensions, social security and thing that are paid out month by month will be taxed in proportion to the time of residence in one state or the other. The sale of the house, however, took place as a single event on a day after our transition to WA, so that is not taxable in CA at all. Am I thinking about this the right way? So far so good.
b) to bad about the taxes on the CA house (in 2022) That is going to be brutal. We owned that house for 40 years.
c) It was rented until the middle of 2020 and vacant from then until the time of sale.
Thank you for the detailed and informative answer.
