Why partner vs going at it alone?

[Ryan Moore]

I own 1 multifamily property that I purchased/financed on my own.  I'm currently in the process of saving up to purchase another similar property (which has been a slow process so far).  I've thought about getting that next property sooner by partnering, but I'm not 100% sure why I would want to do that.  What is the benefit of partnering to purchase a buy-n-hold vs going at it alone?  

Sure I will need to contribute less money in a partnership then I would on my own, but the wealth building benefits are also diluted.  So while my snowball that I'm building gets a little bigger owning 50% of a property vs sitting on the sidelines, if I save up to do it on my own, that snowball gets a much bigger boost.
