Investment Banks and Investors

[Deion Alaei]

Hello,

Let's say a real estate investor is trying to finance a commercial property with investors through an investment bank.

If he/she contacted more than one investment bank,
and more than one responded back with interest and wanted to do business with him/her further, what would be the right and ethical thing to do for the investor?
Should he/she respond to both or tell each of them that theres another investment bank thats interested or is that disclosure gonna upset them?
It can be a delicate situation for a real estate investor raising money from an investment bank for the first time, and I just wanted to know what would be the proper thing to do at that point when he/she is faced with multiple interested investment banks?

Thank you
