Receipt of inherited house which was a rental property with an ultimate sale of said business property

Convoluted, but heh there has to be smarter people than me who can answer this.

House in a trust after death of grantor.  Grantor passed 12/1/22.  House was idle.  House was rented May 2023, income received, expenses recorded, profit made.  August 2024 House was distributed to a beneficiary's LLC.  Rent continued at a profit.  In December 2024 the business property was sold at a material loss i.e. December net proceeds were materially less than adjusted basis inherited from Trust.

Question 1

For the period of August thru December (beneficiary LLC tax return) rental income is recorded on Sch E, yes?

Question 2

Given that the rental business property was sold at a loss would this loss be picked up on 4797 AND considered ordinary Loss (which could be carried forward assuming it is greater than AGI), yes?

Question 3

Would the basis be on the date of the death of the grantor or when the beneficiary LLC assumed ownership?

Question 4

Would the basis be Adjusted Cost basis or FMV (stepped up basis)?

That's it.  I would appreciate a stab at this.  I have limited understanding, but will find the answer eventually.  thanks.
