Tax Pro help: Benefits for Buyer of an owner financed multi-family?

[Randy Winzeler]

New member looking for tax advice on first RE deal.
Looking to offset taxable income of my current business income while investing in a rental property. Found a deal on a Duplex that owner is offering owner financing.
As a possible buyer of a duplex that is being offered with Owner financing. Can I still get the same tax benefits in regards to depreciation? Cost segregation? 
Obviously owner is Seller financing for their own tax strategy purposes so wondering if that affects the advantages on my end as the buyer?
Thank you in advance for any and all help.
