I'm a little late to reply but don't worry about the value of your house. My husband gets all caught up in that. Honestly, I just want to enjoy my house for what it is - it is beautiful and if it's not what everyone else wants or where everyone else wants, oh well....
Normally, houses will be worth more than when you buy unless you are in a bubble situation or a seriously economically depressed area from when you bought it. I don't know where you live but if you have a home anywhere in the 250K to 500K range (land or not), I would say you are doing just fine. And.... you can always update it.
No prob, I've been gone all weekend myself. My point is, the older houses in my neighborhood are being razed and million dollar mansions are being put in their place. What does that make my house worth if it's not updated? Is it just worth the land? I dunno. It's worrisome though.
