How to carefully vet a house flipping partnership

[Account Closed]

Hello Fellow Investors!

I have an opportunity to invest in a house flipping opportunity in Southern California with a partner that has 5 years of flipping experience. The deal has a 10-12% projected ROI and is expected to be completed in 3 months.

This is my first foray into flipping so I would really appreciate if you can educate me on the type of questions and documentation (if any) I should be asking for to mitigate my risk.

Thanks all for your time & guidance.
