Autumn Properties investors fund a specific real estate project and earn between 10% and 18%. ROI.  If an investor funds an entire project, a joint venture, net profits are split on a 50/50 basis and investor is guaranteed a first lien on the property.  Partial investments in a particular project require a minimum of 25% of the purchase price, 20% of the rehab cost and 6 months of holding costs with interest paid on a monthly basis.
