No it's not trivial - for the simple fact that the MLS don't want you to have the data. (Barrier to entry). You can find broker's but their fees are high. Otherwise, you have to become a realtor (or get access via a realtor's access - which can cause problems for them). Nationwide, you would need IDX connections to many MLS which they're protective of. You can scrape Realtor.com's website , but it's in violation of T.O.S. It might be smarter to use Trulia or Zillow's API. Source of knowledge: Founded 1 Single family, and 2 multi-family companies.
