Oh yes you can be very very wrong!
Hey raptor: you've got everything all figured out huh?!
What if you lost your job which is what likely to happen during a recession, and must sell the house? What if you are relocated to another city or country and must sell the house? In your personal case, you are damned lucky, for the past 5 years the real-estate industry has been expanding like crazy, but will it continue for the next 5 years??? No one knows!
Buying a house should be a decision based on your personal needs: for instance, if you have kids, you probably need a bigger place, so a house would be ideal; if you want to stay in the same place for more than 5 years, sure, it beats paying the rent. While owning a house may be beneficial to the majority of the population, it may not fit your priorities. Many have mentioned that owning a house is a good investment, and I agree, in many cases it is, but all investments involve risks, it does not GARANTEE positive returns! Real-estate is relatively low-risk compared to other industries, but since this is probably going to be the biggest purchase of your life, I recommend doing some research first and sort out your own needs. PLEASE don't just buy a house because your friends, neighbors or colleagues did so!
