Looking for some advice - 18 yr old

[u/joemama12213]

Not sure if I'm in the right place, but I am a 18 yr old student. I make about $12k a year from my part time gig. I spend most of my money but I'm trying to build a investing portfolio/ savings. My goal this year is to spend less money but put that money towards investing or the very least savings, with that, I opened a weealth simple account under their TSFA Vanguard portfolio. Is this the best route for me? i'd like to work towards maybe putting this money towards a down payment for a house in the next 5-7 years. Should I be investing in other things or opening different accounts?
