It's all mine, well ours

As of about 8:30PM March 31, 2006 7830 Sandpiper St belongs to me and my bro. After about 3 months of shopping, countless houses i've looked at, 2 lost houses, we finally got one. Possession date will be April 15. I thought I would be more excited about buying my first house but I'm really not. I'm not sure what's wrong with me. I feel like I'm buying something from a store. Shouldn't I be more excited?
