Death of grantor of Revocable trust and future taxation

[Justin Summers]

My Mother passed this year and had all her real estate (8 rental properties netting about $100k per year)  in a revocable trust I'm the trustee of the trust now. 

It's my understanding that the trust has automatically become an irrevocable trust upon her death and my plan is to obtain an EIN for the trust. 

My self and 2 siblings are the beneficiaries of the trust.  

My questions.

1. Will the trust take all the expenses and depreciation deductions of the rental properties on it's tax return and then just distribute net income to the beneficiaries having them pay taxes on the net income on their K1? or are the deductions taken on each beneficiaries tax return? 

I have been distributing monthly payments to each beneficiary just under what I anticipate will be the net income and then plan to distribute any left over profits in December of each year to the beneficiaries 

If there are different ways to do this I'd like to hear pros and cons.  

Thanks for any input
