Looking to locate list of asset management companies. Prefer list with Contact Name Phone# address and email address. Any Idea where a list like this could be obtained or purchased?
Our company renovates foreclosed vacant properties. These are our optimal customers. We work for a variety of lenders and are the preferred contractors for such.
And Asset management companies often control properties across the country. (I.E. this week we have a project in Detroit that was hired from an Atlanta REO Management Co.)

I own a real estate investment company. We buy and sell residential and commercial real estate. I am looking to see if email lists are available for groups of active real estate investors/investment companies. Obviously, I want them to be opt-in lists open to receiving listings of properties we have for sale.
