Home purchased in 1993. Community Property state (Arizona). Initial title held as husband and wife joint tenants with right of survivorship. Spouse died in 2006. But looks like death certificate not filed with the county until 2013 when home refinanced by survivng spouse. What year assessment is needed for the adjusted cost basis? Can we use 2012 (the oldest info easily available with online records)? Thanks for any thoughts. Do you need more info to answer?
