I often see people do one or two mailings and then give up because they didn't get a deal yet, or pause their adwords campaigns, or stop driving for dollars, or stop cold calling, or fire their SEO manager...

Use any combo of the above and mail or cold call.Other methods are driving for dollars, door knocking, wholesalers, craigslist, Realtors, FSBO sites, expired listings, put out bandit signs, billboards, newspapers, other offline publications.You can use pay per click/adwords, motivated seller website with SEO, facebook, Linkedin, Youtube, and other forms of online and social media marketing.

Just a few of the many things to consider when optimizing keywords/ad words campaigns.

You can target tired landlord, vacant house, inherited house, divorce, job transfer, money problems with SEO.I compare list to Adwords.

What would be some effective keywords that would me gain traffic to my website when working with google Adwords?

He was being called by Google about ad word advertising on his handyman business and didn't know where to begin (kind of like me with RE Investment!).  

A few pieces of advice.1..Get a .com address if you can.2..Understand that unless you want to spend money on SEO (Search Engine Optimization) and advertising (Google Ad words etc.) you are probably not going to dominate, at least not initially.

If you want to go the opposite route you can spend a good amount of money making your website a fantastic resource, you can then use ad services like Google AdWords to drive local traffic to your site. 

The Google adwords keyword tool will tell you how many searches there re for a particular keyword or phrase.
