Ann, in response to your question about Adwords vs. Trulia & Zillow advertising, I have to be upfront and say that I don't get many leads from my Trulia Pro plan. I also don't have a big buy-in either, so I kinda expected that. As to whether or not I would give Adwords priority - it sort of depends.
Adwords is probably best used in conjunction with content marketing. Again, you could actually buy display ads on Trulia/Zillow/Realtor.com (and I've seen agents that do that) but you are not going to get the concierge service that you get from Trulia's built-in lead system...so you have to build that part on your own website.
For example, if you created the 365 blog posts and created the associated images, you could set up a campaign that rotates though those in the sidebar on these major real estate sites. The visitors wouldn't see the same image over-and-over again like I see the Capital One Mortgage ads and the Auction.com ads. They might never see the same ad twice and with 365 different bits of info, you have a big chance of hitting a chord with them and getting a click-through to your site. Once you do that they are tagged for Remarketing everywhere.
Also, if you've bought an ad package with Trulia and the prospect converts to a lead through the standard system here, they might just uncheck everyone's box except yours because your face is most familiar.The trick is building the content.
As to my BEST method to earning leads...without any doubt it has to be networking. I've going to real estate investor meetings and participated and built relationships and earned more deals from that than anything else. I'm switching from that to content marketing because I want to sell higher-end homes from here on out.
