Real Estate Operations

So, now I'm looking for a national property manager to invest in. All Property Management points to Kravetz Realty Group, but I don't think they're publicly traded, and they don't manage single family homes. The link is to e*trade's list of real estate operations companies, but many of them seem pretty exposed to losses in their real estate holdings.

I guess it makes sense that if you were making money managing other people's property, you'd eventually start buying it. But, I'm looking for a pure play. Ideas?
