<prompt> Human: Okay I may be wrong here but this is an idea which I will most probably take on when I leave school, I just wanted youre thoughts on it. I live in Sydney, Australia so prices are more likely to be much higher than the UK, US and even EuropeI am going to get a qualification for plumbing so before then Ill be earning peanuts. But once I get the qualification Ill be 20 years old I can start making good money.Ill be earning 500 a day, 6 days a week. So I will be earning nearly 3000 a week, 12,000 a month roughly which is good enough itself and leaves me with a wealthy pay check.Next step is investing, Ill buy a 500,000 apartment. Ill pay for 100,000 which is 10 which means I have to pay back a 400,000 loan. This means I have to pay the bank 2000 a month. With the money I earn from being a plumber I can easily fit another 500 into that loan so Ill be paying 2500 monthly.Ill pay off this loan for about 4 years which means ive payed off 120,000 out of the 400,000 loan. Then I will sell the apartment. With the property prices sky rocketing here in Sydney I could sell the apartment for 600,000 easily. This means I made 100,000 profit. From here I can now buy and rent out two apartments, or one apartment which is more expensive. This process will keep going on and on, hopefully before I am 30 I can quit my job and become a full time investor and make a larger income then being a plumber. From there I shall hunt for more properties and get more and more dosh in my pocket. I am sure about this and I know I can become rich off of this I just need to follow the golden rule.The golden rule is to save the second I leave school. Not going to waste it on cars, girls, drinks and going clubbing because that isnt worth it and when youre 25-30 youll regret it like most people do.Besides, a beer here in Australia is 10 now. It cost like 70-80 to get hammered, and thats just on beer! R.I.P Whiskey, Vodka, Scotch.Assistant: Another thing that jumps out at me is that by paying 2500 a month on a 400,0000 motgagw you will have paid off 120,000 off after 4 years. Um no... Not even close. What you pay on a motgagw is mostly interest for the first 10 years. Without running an amortization calc Im guessing after 4 year you may have paid off 25,000- 30,000 not 120,0000Human: If I pay 2500 a month on the loan, thats:2500x12 30,00030,000x4 120,000Paying 2500 for 4 years equals 120,000 which is a lot of the loan covered off, but instead of paying for the whole loan and waste 10-15 years I can sell the property which will be more than what I bought it from. Trust me the property prices in Sydney are some of the most expensive in the world.  <response>: But... But thats not how that works. Like he said, youll be paying mostly interest which IF Im correct, means you wont touch the principal. Im not trying to shoot you down or be rude, but it seems like every person has tried to be polite and give you pragmatic advice and you just shoot them down with another reason your plan will work. If you were not going to listen to advice, then why did you post this? If you are confident in this plan and unwilling to listen to sound, objective advice, then go for it. I have lurked here for a while and posted a couple of times and from what I can gather this is a great group of folks who, generally, know what theyre talking about. My advice - be wise, and listen to them.Good luck on your plumbing gig!
