Writing posts on your social media channels about what you do/what you are looking for in real estate can be very effective. Your friends on your social networks will seek you out when they have questions or leads that can turn into great deals.
On YouTube, create your own dedicated channel and record a video on your flip camera or iPhone speaking about yourself and your business in real estate. Put “(Insert City) Homes for Sale” in the title and video description.
Remember, YouTube is the second largest search engine next to Google, so you may be able to generate some good leads. Promote your channel via your other social media networks.
