NDA Issue/Investor Is Violating NDA TERMS

[Leticia Wright]

Good morning, I'm curious about an issue that I'm having. I have been bird dogging for an investors for sometime now, and I have sent them multiple deals. None of the deals has ever closed before. I finally found a property that the investor is scheduled to close. The only problem is, they are not wanting to pay me the agreed upon full amount per the NDA. They are wanting to give me a fee, rather than a percentage. The NDA clearly states that upon closing on the property, a percentage of the purchase amount would go to me for the finders fee. Is there any way that I can get my full payment, that was agreed upon within the NDA? Any advice would be much appreciated.

Thanks in advance!
