My friend had a revocable trust she set up in 2007 and amended in 2016. She died on August 24,2025 - the trust became irrevocable and I became the successor trustee.  An EIN was established.

 

The deceased primary residence was in the trust and she had lived there 30 years .  Here are my questions

 

What is the date the cost basis for the home determined?

* The original cost for the home?

*The date the trust became irrevocable?  If so would the cost basis be the value of the property or comparable property at that time.

 

*The date the home was actually put into the Trust  ( 2017) .   Would I need to find a way to determine cost?

 

*The date a second mortgage was taken out on the home and the value of the home at that time. ( 2022)

    If the trust was a standard grantor trust (aka revocable, living etc.), then the basis of the home would be the fair market value on the date of death (which would also be the same date the trust became irrevocable).
