You just need to network locally.

@Mateusz SkibaRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

@Gagan Yalamanchili, friends and family are where 99% of people start raising investor capital.But raising capital is like any other sales process: you need to get people to know you (network a lot), like you, and trust you.

I'm honestly surprised to see someone with such a big portfolio feel this way- when you have THAT many properties and are still stuck on the mindset that the market dictates your success, it makes me think that you are either not networking and building a professional team around you or you are investing in a market that has lower appreciation and higher cashflow, which can be a real slog and tends to be highly active with smaller actual returns.
