Wa hard money lender/ wants a do not compete signed.

[Ezra Simon]

I quit my full time job seven months ago to start a business with a financial partner flipping houses. It's been a slow start getting systems in place starting out but are currently about complete with our third project. As a LLC we need to sign a operating agreement so I can write things off on my taxes. He wants me to sign a do not compete in the agreement saying I won't flip outside the company with other investors. So here is my problem... my two partners are only wanting to use cash for everything we do which limits us to only three on the books at a time split three ways. I am wanting to start creating a rental portfolio for myself and flip several more a year with a hard money lender to help balance my budget. Is it normal for money lenders to use do not compete clauses in there paperwork??? Any thoughts or advice would be grateful.
