It's a way for us to keep a similar amount of $ going into our housing but shift it from paying rent to someone else to paying ourselves for my current roommate and myself, and my girlfriend hopefully gets to keep her current house and she also gets to keep her mom close, which is an important factor to her that I won't discount.

That percentage would shift as I move up in brackets.Just my thoughts as a non professional financial guy. 

I tell them that they can put day shift and night shift guys in there, and provide an extra set of sheets. 

Also, some costs can be shifted to the agent by the broker as well.

The upside to making this shift in my opinion is again the experience in marketing, engaging with customers(buyers/sellers), and surrounding myself with other like minded people.The downside is, at a starting position in a marketing department, I'd be lucky to earn half(or maybe even less than half) of my current income!

For me it has been all about education, relationships, mindset shift, and being comfortable with being uncomfortable. 

Last time I looked it was around 600K where the tax advantages shifted from LLC to INC.But I'm a dummy, so talk to an accountant and a lawyer.

People have abused the relatively flexible partnership allocation of the partnership items in order to shift income or loss from one partner to another in order to save taxes.Thus, IRS has a framework that can reallocate the partnership items based on the “ partner's interest in the partnership” if IRS determines the method of sharing the partnership items lacks the “Substantial Economic effect” (SEE)To meet the SEE, there are strict rules to maintain meaningful capital accounts including Deficit Makeup Requirement for those accounts.With the requirement, the partner must at some point contribute sufficient capital to eliminate the deficit, and, that way, the partner has the burden of the loss that partnership has and the allocation of the partnership will be respected by the IRS because there is SEE.This is a very high-level summary of the rules and is not comprehensive. there are many exceptions as well. 

@Nick Winikoff I think you are seeing a huge shift because of VRBO and now Air BnB.

There is some evidence that suggests this might be shifting a little bit for millenials et al, but I still think size is king here.
