@Jorge Leon I was always very skeptical of direct mail but I recently had a client do a huge direct mail campaign and he landed a couple properties that made him huge profits.  

Neil, why dont you try what i did and work with a company to do a marketing campaign for the areas you are looking to invest in. this can be a great way to get GOOD deals that your wouldnt get otherwise, down side to that is that many people are sending letters and post cards and what not, so if the area you are looking at is saturated with those already your response may not be as good. but if you pick a good area you will do great, my partner and i picked up 3 properties in 1 month. also if you are having a hard time finding deals, you can always find the people with the deals and help them finance it, you would make money and you would get to see how the process works a bit before you have to do it yourself. private money lending can be very profitable. and there are several ways to structure the deal to make it work for you and the person your lending it to. hope this gives you more ideas...

I'm starting my campaign next week.

I started an aggressive advertising campaign not to long ago to find more deals and expect to have them flowing in at any moment.  

Your other option is to do a direct mail campaign and try and find sellers on your own, this is probably what I would do because owner financed deals are pretty rare on the MLS 

Once you get a property or two under your belt, you can reinvest that capital to start marketing campaigns, etc. 

I want people to SELF SELECT into my campaign, to respond to my messaging, rather than me calling randomly and trying to FIND the right prospects...

I'm interested in rehabbing and I would like to start a yellow letter campaign when I get there, but I feel as if I would have no idea what to offer on a property to even get it at a good price.

Do you think it's possible  to do a marketing campaign  and wholesale  properties  from another country ?  

I'm wanting to start a direct mail campaign to get my 1st deal.
