I have posted a similar question in the Business forum, but it may be more appropriate in this forum. I have read from multiple sources to avoid using the real estate SIC code 6531, when registering for a Dun and Bradstreet number, because it is a high risk code for real estate investing. I would like to know if anyone has had success with using this or if anyone has structured their real estate investing company/corporation under a different SIC code in order to avoid being flagged for business financing?
