CrowdFunding platforms are popping up everywhere to cater to the Single family property flip investor. While I always have recommended working with a local private money lender or broker, crowdlending is taking off right now and these guys (platforms) have been able to build a remarkable trust with investors hungry to put up funds for a share of a note investment. Investors are actually getting a share of an LLC that owns or manages the underlying note. The LLC is typically managed by the crowd-funding platform.
One of the most popular real estate platforms out there is Realty Mogul you can visit their rehab (borrowing) page here http://www2.realtymogul.com/rehab.
Here is a list of online crowd-lending platforms that are funding residential rehab loans in most areas.
