I literally took out a mortgage to buy my house. That's financing.

If I lose my job and I'm not able to find another one then the bank will repossess my house, but that doesn't make my purchase of my house a financially irresponsible decision. The repayments on my mortgage are considerably less than the rent that I used to pay, so I am much better off now than I was previously. Anyway I would have lost my rental had I stopped paying as well, so nothing's really changed.
