I found some really good reports/slide decks that illustrate how even the tiniest of changes can increase or decrease response rates:http://www.the-dma.org/whitepapers/TestingDMWhitePaper-GAWrightFINAL100305.pdfThen some metrics about direct mail:http://www.ruthstevens.com/pdf/Allegra-DM-White-Paper-FINAL.pdfHead on over to Sharon's blog and watch her video interview with Joy Gendusa of Postcardmania and then pick up a free copy of Joy's e-book on postcards and direct mail:http://louisvillegalsrealestateblog.com/amazing-entrepreneurs-interview-with-joy-gendusaDan Kennedy has a ton of books on direct mail marketing that are filled with some excellent points - if you have an Amazon Kindle, you can check out some of his books for free - start with the relevant titles first.I've got two more months of postcards queued up before I can start doing any real testing, but I was able to expand my list to just a little over 7500 names, split it into 4 groups of almost exactly equal size.

I know of may Australian investors that have used their services.

There was a group of Australians who bought up everything here a few years back, and now they are all gone.If I could find a refi bank that would do 20 or 30 years at a decent rate, I'd give them the whole  LLC portfolio.  13 Properties, 22 units.

AU  its the Australian version of  BP  back in that time Aussies were buying the heck out of US properties so I was lending my opinions on where and what to watch out for.. that is what led me to write the e book perfect storm for out of state or country investors.. 

We are up in the Cleveland market and have worked with countless Australian investors.
