I do a lot of repairs and maintenance at my own house. Last year I built a terrace and an extra room, and only had to pay someone to help me, and this week I painted the all house exterior with the help of my dad. Total costs of painting and entire house: 240€. It would cost north of 2000€ if I had to pay someone to do it.
Yes, my "hourly rate" for that kind of work is sometimes much less than my "regular" work. But I can fix many things, don't need to go find "credible" people to do things for me, I fell an immense pleasure to be self-sustainable (for that kind of things), learn a lot; and my house, cars, electronics, are mostly in top shape.
