What is the best way for an undergraduate to save up for a house within 5-10 years all while studying?

1) Increasing your principal

Look at your current expenses and try to cut them as much as possible! This way, you will have more spare cash which will serve as your principal to invest regularly, aside from doing a lump sum investing. The power of compound interest should not be underestimated! Always be investing into your future regularly, you will be grateful to yourself in the future :)

2) Investing

I would recommend putting half the money into money into S&P500 which will guarantee about 10% returns. (around 14k after 4 years) and half into more risky individual stocks. You may consider disruptive tech company stocks, as they have shown exponential growth rates in the last few years.

Are you working part time? how much is your income?

investing has its own risk....

my advise is access you risk, access what type of house u are looking at? so you know how much need to have by 10th year of saving.

normally its good for couples to save together ..

Keep a saving account that you do not use, stash cash there monthly.

Periodically, like every quarter or half-yearly, you can review on whether to use the cash to buy stocks or invest in ETF.

1-3 years befoer buying house, you should probably start to keep more cash rather than stocks :)

Depends on what kind of house you are looking at. Is it private, hdb?

What kind of loan you want to take? Bank or HDB loan (if allowed)?

How much are you going to set aside as cash/cpf?

You will need to answer a whole lot more of questions, including,

(1) Ability to take risk (short, medium, long horizon), and

(2) Willingness to take risk (You can sleep even with stocks getting 30% down or even 50% down , e.g you invested 100k and now only left with 50k),

5 to 10 years could be a good chance for markets to recover and take a profit, but past performance does not indicate future performance. A U-shape recovery can also lead to panic selling later.
