Good job mate,

Well let me share my small biz experiences;

1. Car rental
Capital : 7k
a. Car itself = 6k
b. Repairing and stuff = 1k
Services: Very subjective, mine has taken up 3k for 3 years.
Location : Inside university
Monthly/Yearly Income : Average 500/month, 5k/year
Duration : Manage it for 3 years and plan to sell it off soon (I've just graduated )
Opinion : Extra pocket money and after all provide me a free transportation

2. Food Trader
Capital : Own transportation needed
a. Collect order and buy from the restaurant and sell to student
Location : Inside university
Monthly/Yearly Income : Earn some profit margin each pack, earn up to 500/month, 5k/year
Duration : 1 year
Opinion : Very time consuming and decided to stop after doing car rental service

3. Book Trader
Capital : 0
a. Buy from senior and sell to junior
Location : Inside university
Monthly/Yearly Income : Earn some profit margin each book, earn up to 1k/year
Duration : 1 year
Opinion : Very time consuming and decided to stop after 1 year of doing it

4. Phone Accessories Trader (Failure)
Capital : 0 (My parents own the shop)
a. Collect order and buy from parent and sell in uni.
Location : Inside university
Monthly/Yearly Income : Earn some profit margin
Duration : half year
Opinion : Very less customer (lack of advertisement and quite busy in uni too)

And now I graduated as an engineer in first class honours and decided to join big companies if they want me.. Many have rejected me

As for now I have some capital burst up from the previous biz and education loan and is planning to open some other biz or I would just wait to work as an engineer profession to burst up more of my capital

Yeap totally agreed.
Having a profession is better than working in small business, unless when we have a bigger capital to run a big business then it would better than working for others.

I was planning to invest in property for renting maybe while working as an engineer.
And am wondering how to get bank loan approval for no pay slip

That's true, well besides housing property, I still need to buy a used car (current car breaking down soon) worth 60k. And if i were planning to put a large down payment, there goes my capital Am planning to take 5 years loan and after that I should be able to invest in housing property, I am not sure if this is this the proper way

Thanks buddy, posted there, do come and share
