Nowadays with social media you can get a good idea of how they run their business.

@Stacey OlsonRecommend 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.

You're running a business...you are not a social services provider. 

Things like a website, an email at your domain and credible social accounts (even small things like a profile pic and bio) can show you are a legitimate business.

I own Granite and Pine Properties - a Direct to Seller Marketing company that focuses on giving sellers 3 selling options. https://graniteandpinere.com/My advertising is word of mouth, social media, SEO, mailers and cold callers.

Door knock, cold call/text, mailers, social media, etc. 

Good Morning,I am a former Claims Specialist with the Social Security Administration and currently unemployed homeowner who is looking for guidance on how to gain property management experience here in the Central Coast of California.My wife is the only one working at the moment, so times are tough to say the least.We're looking to rent out a portion of our home in order to save up enough money to purchase our second home (or multi-family unit), rent that out, and begin to expand our portfolio. 

I think she is equally responsible if she is 50 / 50 ownership per the offering and through thier own discussions on podcasts, social etc. 

.: I would never give the party on the opposite end of the transaction POA over the property, or my social, DOB etc.

So, I guess I will hope social security pays something in 20 years and the stock market is still there when I grow old.BTW, I am an experienced investor, I know I can dump everything in the stock market but I am hesitant to do that.
