The deals I run across in need of equity sharing typically involve rehab or construction/construction completion. Giving up a portion of your equity or profits is a good idea when you have profitable deals but not enough cash to work with to finance them. A lot of people I work with bring in a joint venture partner who has cash to work with. In this situation, the JV partner puts up the cash needed in exchange for a percentage of the profits when the property sells. While this may be a large dollar amount, it allows investors who are just getting started or have little cash to work with to get involved in real estate investing.
