Private Lenders

I’m based in NY but have 3 apartment properties that I’m buying in Texas. I have the teams already in place to come in and manage them as well as what value plays to implement. It will only cost me $675k (two are master lease w/option and the other is a partnership with a motivate seller) to get into all three within the next 10-14 days. What would be the best way to find a private lender to loan the money for a double digit ROI that’s secured by the mortgages?
