So my past borrowers that I have financed through Wells and Taylor Bean are getting letters about Obamas Homeowner Affordability & Stability Plan (HASP). Refi for no cost, lower the rate, etc. Is this common now that the lender I brokered a loan through is going to market and refinance to my database? Is the Government compensating them to refinance these loans that are current? By how much? What can I do?

Be proactive and market to your database.  What types of rates are they offering?  As long as you can compete, you will win your past customers back.  They trust you from the last time they dealt with you.
