As a current undergrad planning for my future, I am thinking of investing for housing and wedding in 8 years time. What is your advice?

Hey there!

With wealth accumulation, we need variable and guaranteed sources of income. Because your long-term need is certain and guaranteed, you might want to consider a guaranteed source of income such as an endowment. Do make sure the endowment fits into the time horizon of your needs and if you can commit to it!

Have you done your budgeting for your house and wedding?

You can use the tool here for an approximate cash house budget:

Once you have done your budget. Ignore the returns first and foremost. Focus on how much cash you need per month to hit your goal in 8 years. Returns can come later if there is shortfall. Considering that in 8 years time, your cash need is a guarantee, I will be weary about suggesting non-guarantee placement of funds. Especially if you have intentions to fully fund your plans from those investments. You would want a certain portion to be in assets where there is a level of guarantee, and the rest be allocated towards growth.
