The main difference between crowd funding and crowd purchase is that with crowd purchase all of the investors own a share of the property purchased.
Investors are also gifted a share in the property management company which is responsible for the development, letting and sale of the property aquired.
Crowd funding is usually a loan of money to a business project with no additional security offered to the investor.
In 2015 over $34 billion was raised worldwide through Crowdfunding, the estimated future growth of the Crowdfunding market is estimated to be at $300 billion by the year 2030. – https://www.crowdcrux.com/
Crowd purchase is used solely for the purchase of commercial investment property with the main aim of creating a rental income stream and increasing the capital value of the property to provide the maximum level of returns for the investors.
