@4x4toy I did that for almost 3 years. I cleared my car loan, some other debts and set myself up very nicely with a large deposit for a mortgage. Had ~40% of the house cost at the time of purchase, and money to do it up the way I wanted.
Once I was in I'd say it was 2/3 months before I stepped back massively. Sure I could have continued on and cleared off the mortgage in a few years but I'd next to no social life so what is the point.
Working a decent job now for a good bit less money but I'm out the door at 4:00 pm every day, and every evening and weekend is my own. I'm definitely much happier this way.
