SEO.

Hey @Amy Ranae,This would depend on the type of leads you're targeting - sellers for retail/end user buyers, distressed sellers, probate/divorce sellers, etc.Generally, I'd recommend - Cold calling, postcards, social media advertising and SEO marketing (this will take the longest amount of time to yield results).

High equity, absentee and vacancies are very common and everyone mails them.Maybe go to a local courthouse to pull recent divorce filings or eviction filings to target what may be tired landlords, though for all I know you can buy those lists as well.Let me add to this handsome feller's response.You should look into SEO leads.There is nothing better than a lead that is eagerly wanting to sell to YOU... so much so that they are the ones looking for you instead of you looking for them.People chase me, hunt me and harass me non-stop to please come by and make them an offer.Those leads are called inbound leads, and when you get these you will be shocked how different it all is compared to outbound leads. 

The only thing that matters is they are motivated enough to sell below market value.This is the results of internet and SEO.

Think with enough SEO you might get some traffic on the turnkey side. 

Go buy how effective the marketing is.If you want the cheapest way (free) yet the most effective way... that is SEO.

Thanks for explaining this so effortlessly, @James Mc Ree.

So you can focus on lead generation, website, and SEO, etc.

If you all at once start a DM campaign, facebook campaign, PPC, SEO, driving for dollars, cold calling, SMS, etc., you'll have a tough time.
