Wholesaler asking for POF and to sign a NDA

[Jon Robinson]

Hi, I have a wholesaler who texted me a deal for a 57 property portfolio, so I said sure I'll take a look at it send me an email. He replied I would first need to sign a NDA and show POF before he sent any more info. This would be my first time working with a wholesaler so my question is if this is normal? I know that this is a larger deal so some amount of confidentiality would be required but he is unwilling to offer any information outside of the asking price and a cap rate. Just sounds a little fishy to me.
