Marketing to Multi Unit Owners

[Matt Faix]

Does any one have any tips or examples of what you would include on a letter to owners of small-mid sized apartment buildings, or how you would modify your mailers for bigger properties with more experienced owners (5-20 unit properties). 

I'm inclined to think that postcards / yellow letters may get brushed aside, so something that looks like a bill or an official notice may do the trick, possibly with a more formal message inside? Rather than the "HEY WE WANT TO BUY YOUR HOUSE, CALL US ASAP" message. Curious to hear everyone's thoughts and experiences with this. Thanks!
