Tips for structuring partnership

[Abby H.]

Hello Bigger Pockets community,

I have been an avid Bigger Pockets student for the past two years and have since bought my first house and strategizing for house #2. There are some seller finance deals in my area but I would need to go in with a partner for the down payment. My questions have to do with.. as a new investor I'm missing a few pieces to my understanding on how to structure a partnership. Why would someone be interested in partnering with me when it comes to the down payment? How am I offering value/profit to them? What other steps, legally, or otherwise do I need to offer or put in place to make them want to partner with me? 

Thanks in advance.
