You’ve seen every house on the market and you’ve finally found the spot you can’t wait to call home. In fact, you’ve mentally decorated it and planned your new life, down to the barbecues and block parties you’ll have with your awesome new neighbors. Sweet!

Slow down there, dear buyer. As you know, you still have one giant hurdle to overcome: You’ve got to make the offer that wins the house. And in a highly competitive housing market, that can be easier said than done. Don’t blow your chances with any of these common home offer mistakes.
