I just read the post “Builder Blog Basics” on Big Builder’s Blog about Homebuilders and blogs.  I absolutely agree that a blog is a great way for homebuilders to share information and reach out to customers.  Here are some of my additional ideas for posts:

• Home Maintenance Tips
• Home Design Ideas
• New products in the Design center
• Answer Frequently Asked Questions
• Energy Saving Tips

The number of topics related to homes is never ending.  Your customers are looking online for information before they make their home purchase, and if you have a blog full of interesting information you are ahead of the game.
