Investor is selling my note... Asking for too much personal info?

[Nathan Reed]

Hi everyone,

I had bought a SF rental property in early August from an investor that was selling his portfolio. I paid him 20% down and he seller financed the other 80%. Two days ago I received an e-mail from him stating that he is selling the note off to an investment firm and needed my SS# and employment history for the firm.

I'm not just going to send him that information no questions asked. But, my question is, should I have to provide him or the firm any of this information since I am not technically a part of their transaction and what should my response be?

I've never been through this so I don't know what the norm is. Any input is greatly appreciated!
