Engineer quits 6 figure job to build house to sell

My engineer client decides to leave his 6 figure $$$ day job and builds house to sell. He was scared stiff.  I financed his project and advise him throughout the process.  Halfway through, someone offered to buy it from him.  In less than 6 months he made more than twice his annual income.  Now he's scared to think if he had stayed where he was at and only made half of that and toiling away over 11 months of his life instead of 6 months (doing what he dreamed about all his life).  Kudos to you Haibo!  Want to build your own home or become a developer?  I can help and even introduce you to Haibo.
