Seller will carry partial note. What's the best strategy?

[Season Price]

Hi. I have an off market, 12 unit I am looking at purchasing. The seller will carry 35%. Asking price is 300k. Gross income was 67k last year. Profit was 40k. All but two units are rented out right now.

I don't have the 65% to purchase the property nor do I have someone to partner with.

My question is: Is there a way to structure this where I can benefit from the seller being willing to carry a percentage, and then I get a loan to cover the rest? I'm not sure how to put something like this together.
