Seller/Owner Financing for Multifamily Acquisitions

[Ron B.]

I'm looking into buying an apartment building. I'm trying to come up with a good way to present a solid offer to the seller for seller financing that would would be favorable so it would be a very sweet deal for him that he couldn't pass on. 

The property is selling for $3.2m 7% CAP. It's annual Net Revenue is $216k

What's the best way to present 100% seller financing ? I could put down $35k Plus he has security deposits that have a total value of $18k, so not sure if those could be used for the down payment also?
