I completely agree with Vhotee. Back in Nepal, we are used to getting things done for us. If a tap leaks, we call some to fix it. If we need to hang a mirror on the wall, we call some to drill the hole for us. So we never get to do anything by ourselves and do not learn how to use any tools.
Two years ago, I built my house working with a brick layer and 2 other guys. It was very daunting in the beginning but slowly I learned the trick. If you have good tools, some patience, you can learn the skill. So invest in some good tools; you will always need them. My house is worth $380,000 and I got it done at $235,000. I saved more than $100,000 by building it myself.
I have an american friend who quit his desk job. He now builds houses and then sells them back. It takes you 6-8 months to build a house and when you sell it back, you make a profit of close to $100,000. You save a lot of money by building your own house. You only pay for the materials. But you should be ready to work under rain, and do some physical work. But personally, I loved it.
