Welcome to the Q&A Forum

Going to start by saying I'm totally new here, so apologies in advance is this is a dumb question! I run a site that is focused on home buyer education. The site is brand new, so no almost no link profile, and I'm trying to grow my backlinks. On twitter I've had success with real estate agents sharing my articles to their followers, which is great. It helps them educate their customers and feeds the social media beast. I realized that realtors, mortgage brokers, and insurance agents (all relevant to my niche) don't usually run their own websites. Many of these sales people leverage agencies, and often the agencies offer blog posting as part of their service offerings. I'm tempted to do some outreach to these agencies and offer to write guest posts. I figure they get free, quality content and I beef up my link profile. Is this a bad idea? Are there any risks with this approach?
