Agent/investors are used to this sort of arrangement, but it may be hard to convince a traditional "retail" agent to work with you.

Going with one of the traditional brokers you'll most likely start out at a 50/50 split.  

If I were you I would go with a non-traditional broker.

I'm assuming they're Chinese-made laminate, but shouldn't they have a AC rating?

There's about four things youve got to work on to get a fast startWhen you go to learn how to get JV money, talking to doctors and business owners, you find a deal, that needs work, you have money and credit  business partners that will put up hundred percent of purchase price and repair costs, and you sell it and split the profits if you pay back your money and credit partnerYou need to find private lenders who have money in IRAs whether they're in  Roth IRAs or traditional IRAs, but they need a good rate of return with some kind of real estate security.

Where I live in LA, the barriers to entry for traditional home ownership are higher (20%) down.

They can also be faster and more transparent than traditional home sales.
