Do you use the same company for PM & purchasing?

[Chris Virgil-Stone]

I've been looking into investing out of state lately as the Atlanta market is becoming very saturated with buyers. I've located a market I'm familiar with where price to rent ratios are favorable and plan to invest. Up until now I have always self managed. While it was not always the case, I actually enjoy it. I'm very hands off and have automated most process. My property management style and lease are very strict, however I also provide high quality housing slightly below market rates. In order to invest out of state and scale I realize this is not my comparative advantage. Obviously there's many things to consider when choosing a PM company. What I'm wondering is - what benefits/disadvantages have you experienced when using the same real estate company for PM and purchasing vs. separate companies?
