New website is in the google index. How to promote it?

My newest creation – www.nestery.com is now in google index. It took 3 weeks to get all the pages there, but it is finally all in there.

How should I go about promoting this website? I will email all fellow investors I know to add the houses they have to it. That should add couple  hundred houses. How would you go about promoting it for buyers?

My plan:

1. place adds on craigslist
2. respond to adds on craigslist
3. need more ideas…

Anybody has a good idea how to get trafic?
