Through SEO optimization, you can make sure that your website shows on Google's first page or higher on your search results. 

Do SEO, fcebook paid marketing and PPC.Leave everything else alone.

When I was actively marketing (I have been buying 1-2 properties a month on referrals) I was using DMM, bandit signs, networking, and some PPC.Now cold calling, texting, SEO, and social media advertising seems to be the direction that everyone is using. 

Mailers (consistently), Website, Ad clicks and SEOs etc$30,000 - $40,000?

They look great but I am not sure how well it will do unless you are paying for SEO. 

NO ONE mentioned SEO?!

1) Youtube search SEO 2017 or SEO 2018.

@Alex Bradley SEO could be good but make sure the guy you hire has done is for your field before, they need to know which terms to optimize for, Facebook can also be good for microtageting your leads.

You need to get your name and phone number out there in front of people who might want to sell their properties quickly.Common examples are sending letters to owners of properties, for example all out of state owners in a city, or owners who are getting divorced, or landlords who recently evicted someone, etc.Also common is Google SEO advertising, Facebook campaigns, putting signs on telephone poles ("bandit signs"), putting fliers out in the community, dropping business cards in certain locations, paying for billboards or radio or TV ads, etc.At some point you will need to make a decision on whether you have (or want to spend) more time, or more money.

Google means nothing.I do SEO based on my traffic.
