I can't begin to tell you how grateful I am if I can get just a few startup questions answered...ENTITIESReal Estate BrokerageREI Tech Company.comProperty Mgmt CoConstruction CoFinancing CoREI Tech Co Apps/Software (IP Involved)REI Marketing & AcquisitionsREI Fix & Flip Co (Same Co as M&A)REI Buy & Hold CoREI Joint Ventures (Flips & Holds)Q: It's been advised that we separate each division beneath one Parent Company 'PCo'.Our DilemmaThe REI Tech Co would be a platform to make offers, auction, and buy Real Estate similar to RealtyBid.com, Auction.com, and Hubzu.com only targeted toward a completely different niche.We intended to charge a Buyer/Seller premium which would be based on a % of the total offer/listing/bid (TBD) in addition to fees for premium services (featuring property, BPO, web based tools, privileges, etc).No doubt the % would be viewed as a consideration for a Real Estate Transaction so the Tech co would need to be licensed.The buyer would have the option to use our Construction Co 'CCo' for rehabs/maintenance and Property Mgmt 'PM'.
