Hi @Jeff Richardson - great topic!
Here are a my thoughts on generating home seller leads - we've worked with over 1 million home sellers in the past 10 years, so have it down to a science.
The first thing to consider is what you have more of - time or money. You can use both very effectively to generate leads. Most people start out with more time, and as they become successful begin trading time for money.
MONEY options
1. pay per click advertising (Google, Yahoo/Bing) - this is the fastest way to generate leads, but requires expertise, a very well designed landing page, and the ability to respond immediately.
2. direct mail - this is VERY effective for generating leads, but requires consistency and commitment. Being highly targeted is critical to getting a good response.
3. Zillow/Trulia advertising - If you're looking for sellers, you can get a list from Zillow of who has posted their house FSBO on the site, then call and tell them why listing with you is a better option.
4. buy leads - A LOT of companies sell leads to real estate agents. This is only a good option if you have your processes dialed in, and follow up with people within seconds. I would not recommend it for new agents.
TIME options
1. network - this is the best way to generate leads where you aren't competing with dozens of other agents and everyone should do this at the start. Meet with every CPA, title company, loan officer, insurance company, etc. in your town. Help them understand why you will service their clients better than any other real estate agent out there.
2. craigslist posting - I think this is a fairly low value activity because it's so cluttered now, but if you have an angle that makes you different, it can be useful. Title your posts with what a home buyer might be looking for "denton homes for sale" - craigslist posts can show up high in Google search results
3. search engine optimization - don't spend a ton of time on this, but make sure all of your online profiles (realtor.com, zillow, trulia, activerain, yellow pages, yelp, etc.) link back to your web site and that it's properly structured.
4. start a blog - consistently write every few days about real estate in Denton, what's going on, trends, etc. Most of this data is free from NAR and others. Over time you'll become the Denton Real Estate Expert, and gain a lot of credibility with your target market (and all those professionals you are networking with)
5. social media - post your blog entries to twitter/facebook/etc. Post house pictures on Pinterest & Instagram. Be sure you have a company social media profile on all the networks. Provide valuable content that home buyers/sellers are interested in.
6. get involved - community groups, church, school, etc. Most of us know hundreds of people, they should ALL know you are a real estate agent. Wear logoed shirts all the time, have a sign on your car, tell a story about a crazy seller, etc. DO NOT call people you don't talk to often and pitch them - this turns people off bigtime and will put you in the "multi-level market friend" category.
Congratulations on taking the next step in your real estate career and all the best!
