I purchased my own aircraft to do my licence in and I’ve never looked back.
As much as it may not seem to be the right thing to do, I recommend the most expensive / biggest / fastest aircraft that you can comfortably afford as this will stop you from needing to upgrade early on and this wasting cash. You will likely outgrow a 150 very early on in your private flying “career.”
Plenty of people that can afford it, purchase their own aircraft straight up.
