There will always be a better house. But how long do you want to keep looking for it? Keep this in mind while you look -- 12 houses is not that many, really, but 12 months might be! Depending on your price range, you may not find a house you love. If you're on a budget, you'll see a lot of "maybe this could work" places and eventually you'll buy a "good enough" house. Make a list of your priorities and compare the houses you see to that list just to check yourselves and make sure you're focused on what matters (i.e.: if location is your top priority, don't bid on a house where you love everything but the location). Look and look until you're tired of looking and you find something "good enough".
