My boyfriend proposed to me... I'm only 18, should I wait until I'm older to get married?

My boyfriend of four years proposed to me today... We're both 18 and I accepted... We've been going out for four years and we've known each other for almost our whole lives. We've talked seriously about getting married before but I didn't want to until I was able to to pull my own weight. He comes from a very rich family and he said he'll take care of my younger sister and my mother... Medicine money, hospital money and everything else. Even my uni fees. And my dad and older siblings can come home as his dad can give them all a solid job in his company... But this can all officially happen once we are married and they're all in-laws. That is his parent's conditions... He wants to provide us with everything immediately, but his parents said only once we get married.
I wanted to wait until I was a bit older... Maybe 23... At youngest 21. I love him, and he's the one I want to spend my life with but 18 seems a bit young to me...
Should I stay engaged and get married in 3-4 years? Or should I just get married now because he is the one I'm going to eventually marry and my family can also gain so many benefits from it...

People don't seem to understand...
If we get married next year then I can go to university, quit my three jobs, take my mother and sister to hospital and see my older brother and sister and even my dad... I haven't seen them for 3 years...

If not I have to continue selling myself to get enough money to buy medicine for my sister...
That's my biggest concern right now
If I marry now then my family get actually live together. And I'll be with the person I always wanted to marry..
