Buyer Agent's commission and tax write off

[Saika Maeda]

Hi all, 

I'm about to place an offer on a property with an ADU, which we plan to rent it out.

I understand that if I rent this ADU out, then I can have a tax write off on the mortgage payment and insurance payment for the the ADU's sqft portion. Does that same logic apply to "buyer agent commission"? My question is; is it better to not ask the seller to pay for the buyer agent's commission (not include it in the offer letter) so that I pay it by myself and get a tax write off on this commission expense for the ADU's sqft portion? I have a choice to ask the seller to pay for my buyer agent's commission or not include it in the offer letter (pay by myself), so I wanted to know before I submit the offer.

Thank you!
