Your BEST ROI in real estate marketing?

[Jeremy Brandt]

I'm looking for feedback from experienced investors on what your best return on investment (cost per lead, cost per deal, return on ad spend) has been to connect with home sellers.

Primarily repeatable marketing systems, not anecdotal instances.

Example:
Sent 5,000 post cards (6x9 full color) to non-owner-occupants (Cost $2,500)
Received 100 calls (cost per call/lead = $25)
Bought 2 houses (cost per deal = $1,250)
1 wholesale ($5000 profit)
1 rehab ($20,000 profit)
$ Return after marketing expenses ($22,500)
% return on marketing (10% return on ad spend)

We've done everything (Internet, TV, Radio, direct mail, billboards, door hangers, etc) and I'm very interested in what your experiences are - and it's educational for everyone else as well.

Thanks!
