@Christian Nachtrieb The advice from @Chris Mason is good stuff.If your partner's return is fixed (10%) then he's not really an equity partner - he's supplying debt that's collateralized by the income stream of the asset. 

My model has a 60% margin in a house retailing for $40K(if financing was vertically integrated there would be interest profits as well), room for upsells and add ons, offers physically secured properties for financier(permantly set dwelling, not mobile), low startup cost(less than $250K) and the model can be scaled and reproduced anywhere in the US.

My first post, go easy on me...I own a Duplex In the bay area that has an attached ADU (accessory dwelling unit) or granny unit.

At this stage in my life, taking away my greatest expense and generating another income stream is very enticing.I'm hoping to find an experienced investment-minded realtor/broker who would be willing to help guide and minimize the risk of potentially making some crucial mistakes at the beginning that may ruin or complicate the experience. 

I managed a 4 unit dwelling in Detroit, MI.

For many syndicators, this is their active income stream, so they and their team technically trade their time and a portion of capital, for their return.

By the end of your first year, I think having three legs of marketing and deals to stand on is where you should hope to land (this could be your sphere, investors and FSBOs or it could be internet marketing, expireds and veterans the options are endless but the thing is to get specific and become very good at each before adding another stream).The majority of my business came from investors and from my sphere of influence.

would you rather have 1 income stream bringing in $1500 a month, or 2 income streams bringing in $3K a month, with a mere 50% each leveraged... 

in Great Neck/Long Island area.I own 3 rentals currently and am doing the same thing as you, building up the passive income streams so I can finally reach financial independence!

Just so you know, you are in a legal gray area anyway, as the City of Philadelphia does not allow more than three unrelated persons to live in the same dwelling.
