Abstract: Under the background that folk capital provides more financing product for real estate enterprises， according to the costservice matched principle， a selectiondecision model was established for the following decision goals including the lowest comprehensive financial cost and relative high social satisfaction. At the same time， the heuristic algorithm which was suitable for the selectiondecision model was got. The simulation examples showed that the proposed model and algorithm could effectively solve issues faced by smallmedium real estate enterprises in relation to the multichannel financing choices caused by multiple product decision problems.
