You can send letters and email but cold calling is by far the most effective method but you really need to know what you’re doing, how to open the conversation, what questions to ask and more importantly when to listen and not talk.

Then you can mail or cold call or both.Other cheap or free methods are driving for dollars, craigslist, Realtors, FSBO sites, expired listings, foreclosure sites and bandit signs if allowed.If you have the funds you can use billboards, newspaper ads, other offline publications., TV commercials, radio ads, motivated seller websites, SEO, pay per click/adwords, facebook, Linkedin, Youtube, and other forms of online advertising and boosted/promoted social media postings.Bottom line is integrity and consistency.

When I see figures like that, I suspect that the Report has been rigged by someone using pre-determined desired outcomes, rather than cold hard correct analysis. 

Best things I've learned are:Stay extremely consistent with whatever marketing you are doingAttend REIA events -  you'll meet people that will help you tremendouslyTell everyone what you doHave an approachable, trusting attitude when dealing with people, especially sellers - cold feet/distrust are Deal killers!

You will not know if you have a good deal or not until you have looked at enough properties to know the values cold. 

Through a cold calling campaign I've found someone who is looking to sell a property at a good price.

When I didn't, I got cold feet with the cash I had and dumped it into a Roth IRA. 

@Jasmine Nicole like Max Maxwell says, the cheapest way to start is driving for dollars, skip tracing and cold calling.
