Nah. I'm into futures. I probably should be into real estate. I do own a house that is worth probably 500K. BUT: the area around me is going nuts. Which means my house may not be worth squat. They are tearing down all the old houses around me and building million dollar homes. My house isn't modernized. I may be screwed. My house may not be worth 500k. It may be only worth the land.
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.
