I think you may do well with a partnership vs a syndication.  

I'm curious how you guys would structure the splitting of profits on this specifically, and in general on other scenarios as well.How do you guys structure your partnerships if one person finds the deal, organizes rehab, and the other partner only puts up a portion of the cash?

He has the income to qualify for a loan and I’m 50/50, I’m currently working to lower my DTI ratio (currently around 45%) and I could potentially borrow from a family member but my return to them wouldn’t be immediate (I’m thinking a year or so after I refinance)He is willing to front 100% of the cost but how can we create a partnership that will be mutually beneficial.

I would even be interested in building partnerships to be able to provide you with professional property management services in exchange for owner financing on a suitable unit. 

The reason my tenants were still there after they were supposed to vacate was a function of the difficulty for them to find new housing. 

We are also, very open to partnerships if anyone is looking.  

This is where developing partnership and leveraging your network comes into play. 

That's what we're using so thanks for making me aware of this lack in functionality.

Experience can be leveraged into cashflow, and cashflow can be turned into ownership/partnership.

There are several reasons for that,   summed up they are:1)  the duplex is the oldest property (pre-1900) and while well maintained,   is economically and functionally obsolete2)  Located on L2 zoned land  (4 townhouses,   small apartment/ SEDU complex, etc) would be allowed on lot.3)  I was ready to end house hacking,  I had lived in one unit of the duplex since purchase4)  Lower unit (one I owner occupied) not habitable per Seattle rental inspection ordinance.
