Gifted a home from father for $1, he did not pay gift tax, I have reviewed the TurboTax and IRS documents, still not sure

Facts:

Parents purchased this home in 1967 for $16500 + closing costs

My father gifted this home to me for $1 in 2004 after my mothers' passing

My father lived in this home as a lifetime tenant until his passing in 2016.

The house has remained vacant until 2022, when it was sold

In 2022, I sold the home for $150K

Since 2004, I have updated/repaired elements of the interior/exterior and utilities to prep the home for sale.

 

I have been using IRS pub 523 for guidance as well as TurboTax program help dialogs, but am not sure how to proceed. I have kept good records of home updating so I know what I can deduct.

 

Do I use the original price of the house from 1967? or determine FMV from 2004? as basis to calculate gains?
