(Portland, OR) -- The owner of a Portland area real estate investment company has pleaded guilty for his role in an 18-million-dollar fraud scheme. Robert Christensen's business partner Anthony Matic previously pleaded guilty. Prosecutors say they told investors their money would be used to buy and renovate undervalued homes and then rented to generate income. When the plan failed, they started defrauding commercial lenders. They will both be sentenced in October.
