Calculating Basis for property inherited from joint tenant
In 2009, I co-signed on a mortgage with my son to help him buy his home and wound up on the title as a joint tenant. I never made payments on the mortgage or lived in the home. He passed away in 2022 and his Joint Tenant "share" of the house came to me. My wife and I sold the house in 2023.
The original purchase price was about $70,000. At the time of his death, the county established the value of the property at $190,000. It sold for $208,000. (There were associated costs and fees with each of these sales -- I'm just trying to use round numbers.)
I've been told that half of my basis for the home would be the difference between our sale price and the original purchase price. ($208,000-$70,000=$138,000/2.) The other half would be based upon the difference of the value at his date of death. ($208,000-$190,000=$18,000/2.) Is this approach accurate?
I am also at a loss to find an IRS form that handles two basis calculations -- one for each of the different dates I established ownership. Any directions would be appreciated.
Thanks,
Ken
