I am not a realtor so I am not sales oriented, however I want a method to compile a list of "investor" contacts that I could maybe send out emails in mass or something. 

There is no better list than the one you compile yourself, because very few others will have it!!

Newspaper, county recorders office, the auctioneer posts notices on the courthouse (although sometimes people tear them down), directly from the trustee websites and 800 numbers, and there are online services (most common method) that compile all that information for you and more but it is subscription based.

I would highly recommend not going with a $5-10 / month bookkeeper to compile your financials.

I think the best bet is to compile a list of companies that you think have potential and then begin networking with them.

Kristine Marie Poe  was so careful to document rent comps, and stay at arm's length in the compiling of them, when she was writing above.For example, if you jacked up your tenant's rent from $3K to $15K/mo to ensure they would leave, there is an argument that your true intent was to evict the tenant, but because you did not have "just cause" you did it anyway through a different means.

Make a list of cash buyers that have purchased from the tax records, plus wholesalers that have a reputation for selling a lot of properties in your area and start compiling their contact info.

I agree on a price to compile the owner list in excel BUT I figure I won't pay the person until I do 1 mailing and see how many are delivered.This way there are 800 properties to research and get owner contacts for and the VA can't hotdog and only do 4 valid addresses out of each 10 and make up stuff for the rest.

a "finder's fee" for referring clients, or providing 'leads' or 'lists' compiled from the MLS.

If we get enough replies I'll compile it all together into a shareable list.
