I changed a blown light bulb the other day. Certainly beat paying a sparky $90 call out to do it.
Then I changed a tap washer (that is illegal isn't it??) and saved another $90 on a plumber call out.
I am on my fifth house renovation. I reckon I have saved $50,000 with DIY and made about $300,000 profit.
Sold a property couple of years ago, person to person. No agent, no solicitors and no contract. Saved my self about $1,500 and saved the buyer about $3,500.
Mowed the yard myself the other day. Saved myself $50 by not paying somebody else to do it.
Did the grocery shopping myself today and only spent half as much as my wife does.
I reckon you can make a fortune with all these savings from DIY.
