It looks like there are a few different ways to find potential partners - joining an investment club, real estate events in your area, other real estate agents, reaching out to property owners and managers you know, friends and family, lenders (hard money, traditional), financial advisors, crowdfunding, targeting your network (which I am sure you have a great one being a real estate agent!)

I would like to connect with lenders that help wholesaler with double closing fees.

When you've achieved an 80% LTV ratio, you can REQUEST your lender to remove the PMI.2.

It will make your DTI calculation for almost all future investments almost laughable (in a good way) to the lender. 

Hi Ben,I recommend finding investors and private lenders at meetups.

What are the worries and concerns I should have regarding private lenders?

One way is to see if a Hard Money lender would fund 75%-90% of the purchase and 100% of the rehab.

@Tom Server - I think it depends on the lender. 

Have you spoken with a lender about possible renovation budget?
