The only way, IMO, to get partners locally would be to put a plan together, analyse some deals and show them what returns they could get. Doing a residential loan is pretty straight forward. The lenders that help you do a home loan will finance up to 4 units. Just reach out to them.
For your private equity partners, show them the process of finding the deal, acquiring the deal, and managing the asset. They, as a partner get $xxx per month in income as a 1/3 or 1/4 owner in the deal or whatever portion. I can’t see any other way you could attract private money, to give you money, with out that. So I would start there.
You are right about it seeming easy on paper and tough in reality. That is 100% true. It feels like 1/10 real estate investors we help actually do a deal at some point and several of them have hundreds of thousands of dollars sitting around. The market, complexity, and risk are just a insurmountable mountain for the majority.
