If you pay the same amount each month for your mortgage for 25 years and inflation is 2% each year the last payment should be half as valuable as the first (edit: about two thirds, actually. Maths!), so you’re encouraged to buy on credit.
But this is only meaningful if your income is also going up, right? Otherwise you’re still getting fucked by inflation. You’re paying the same percentage of your income towards that mortgage but all your other expenses are going up.
