Trading multiple duplexes / sfr to large complex?

[Brian Jackson]

I currently own ~45 rentals all smaller than 3 units and would like to get into bigger investments.  The problem is I'm not sure how to go about finding an investor or 1031 facilitator to convert 30 or so individual pieces of property at one time.  Any experience with this or with finding these kind of investors?  The full 45 properties consist of ~70 units and generate about 42k/month in rent in Wisconsin.
