It could. But the last two properties we bought were purchased through an agent before they were listed on MLS. I've discovered that there is a pre-sales lag between properties being put under contract and being listed on MLS. Agents call and find out what hasn't been listed yet. It worked out great for us in the last two purchases. But it may also not be typical.
