I don't know how the rest of the readership feels, but I am often amazed when I read what some people – especially from the south of the country – are willing to pay for their own four walls or rather bricks, wood, and land...
500,000 euros loan and about 1,700 euros repayment means a 2% amortization. Even with a 20-year fixed interest period, there would still be a large six-figure amount left after that term, and by then one would already be in their mid-50s... everyone has to decide for themselves, but personally, I still find it very risky despite substantial equity.
