You seem like an engineer, so you should be able to start up a spreadsheet, put down a bunch of reasonable numbers, and project forward 20-30-40 years and see what makes sense for you. If a loan is involved, read up on the IPMT Excel/Google Sheets function! [1]

I don't know how things work where you are, but here in the US if you are renting, you are essentially helping someone else pay their debt. And they can kick you out when they please. The main benefit is that you can stop paying on a much shorter time scale (1yr lease contract?) or take time off, but if you don't rent you should require a smaller cash flow which should be possible to save up for.

One last thing, don't forget that you can sell the property in the future (or even rent it out, hence letting someone else pay YOUR debt). That should factor in your cost/benefit calculations. Even if it does not appreciate at crazy rates like the current insane market has led us to expect, it will very likely be a lot more than zero.
