I think I have a bit of insight into this due to the passing of my grandfather and receiving a post card in the mail (my fiancée and I were listed in the probate) to consider selling the house that he owned.

You can also do this with postcards as well which are less expensive to send. 

There are tons of marketing forums and threads on here about postcards, yellow letters, bandit signs, driving for dollars... targeting probates, divorcees, absentee owners, pre-foreclosures,  etc. 

More than likely, you'll have a more sophisticated seller, so I would assume they wouldn't really respond to the yellow letter and postcard tactic.

I'm much more likely to call one of them (by now I know them all on a first name basis) than respond to one of the letters or postcards that I get from investors trying to buy direct.

And of course, I'm doing your usual driving everywhere, handwriting letters, sending postcards etc. 

Others do postcard style fliers.  

Does any one have a sample of a Richard Roop Postcard For buying houses?

Post cards work best and I also do jv deals as well.

As Jon said, I also don't think this is a peak.Samantha M. he is doing both yellow letters and postcards.
