So why should I buy now?

Because...

1. INTEREST RATES ARE REALLY, REALLY LOW. If you've recently entertained the thought of refinancing or buying a home, I'd recommend checking the latest rates. If it makes sense for you, take the opportunity to lock in a rate before they inevitably go back up. 
2. You can now buy a house with as little as 3% down. There are a few criteria are in place to prevent another 2007 meltdown: the home must be a single-unit, owner-occupied property and at least one borrower must complete a home-buyer education program. That's it.
3. Many buyers tend to drop out of the market during the holiday season, even the motivated ones. Smaller pool of buyers = less competition for you. ​
