Pre-Approval Question

[Mike Repine]

So I'm currently building a new house that I will be closing on the end of July or beginning of Aug. Over the weekend I found a new investment property that I want to move on but I'm not sure if getting pre-approved and signing a contract on it will cause me issues with my new home lender. I wouldn't close on the investment property until after I close on my new house, I just want to lock it down so it doesn't slip away. Also, Is this something that would need to be disclosed to either lenders? Is it unethical or fraudulent not too?

Thank you for taking the time to read my post.
