House valuation

Our neighbor put their house up for sale. The asking price was $30k higher than we paid for ours a few months ago. All things considered our houses are quite similar. Their house is 98 sq feet bigger. Our yard is 1742 sq feet bigger. We have a gas fireplace. They don't. We have skylights. They have none. Zillow.com lists our house worth $3k more than theirs. Needless to say, we'll be looking forward to their open house to see inside. And ultimately to see what the house sells for. Zillow shows our house gaining about $7k in value last month. We'd feel quite fortunate if their house sells near the asking range. We could safely match the value of our house to that value and see our net assets be well above the $200k mark and closing in on the quarter millionaire mark.
