If you look up my company, you will see that we have all of this. 

Of course the co-signer should be significantly stronger in ALL areas as compared to the applicant...usually this is a parent or relative, and they should be well established, with ownership of real estate for years; long and stable employment; no, or very distant, criminal and traffic court records; well funded SAVINGS/IRA's or stock market accounts.

Quote from @Michael Smythe: @Steve K.Recommend 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.

As far as title companies go, I would recommend Foundation Title & Escrow.

Now you have to explain it to the seller, to a title company.

I don't care if the management company makes 50%, 70% or 90%. 

I like to outsource that to a local expert.I call/interview property mangement companies in a city that I like and ask them to refer me to a real estate broker who works with investors.  

And I think I might have mentioned when I had a mortgage fraud scheme come through my HML company a few years back..

I always try and let agents get to know me and my company so they are comfortable with our services before even thinking about referring us!
