Estate Tax Return Income Question

Hello,

 

I've recently been made the administrator of my deceased mother's estate. She passed away in August 2024. She owned a house which was probated to me in May, however I have not assumed the mortgage which is currently listed under her estate. A family member moved into the house a few months after she passed in November 2024 and has been paying rent equal to the mortgage payment, so there is no profit. Would this be considered income that needs to reported on Form 1041? If so, would the income only need to reported up to the time probate was complete in May 2025 or I assume the mortgage?

 

Thanks in advance!
