Hi AraBella,
Thank you for posting this question. I think it needs more visibility. As investors, we hear terms like creative financing, partnerships, or other people's money, but it is a struggle to take a theory and put it into practice. This is a question is one I had as well, so in you asking, I was prompted to dive in and do some research.
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!), online investment groups/investing websites, and social media groups. Reading through all these articles, the biggest takeaways seems to be expanding your network and reach, building your personal brand (who are you and what are you bringing to the table?), having an elevator pitch of what you are specifically looking for, and being ready to pitch yourself and your idea when you have the opportunity.
Reach more people, and be prepared -- seems to be the takeaway. The last 'p' -- just because I love a good alliteration -- seems to be patience. If you are newer to partnerships, you might not have a name for yourself or a portfolio to back up what you are bringing to the table, so it is likely going to depend on how you build relationships and how you can help someone else. That will eventually come around as you become a more established and trusted name.
I'm going to take my own research and start implementing on my side too! This time next year, by doing a little each day, I hope to have grown my network and taken steps in the right direction towards partnership.
I hope this helps! Feel free to connect with me! Good luck!
