It's better to pay the "apartment late fee" the later it is, right? I need to buy a house within 3 years.

I've successfully landed a job... and now it feels like the last remaining quest in my life is owning my own home.
It's probably right to just go all-in and buy a house for now, even if I have to stretch my finances to the limit, right...??
I really need to buy a house within 3 years..
