Need the use of a power saw or a sledge hammer? Should you buy, borrow or rent the needed tool? Ask yourself "Do I really want to own it?" After weighing purchase price against possible re-use, plus storage and maintenance, it might make sense to borrow or rent instead. If it's a one-time job or specialty task, do the latter. But there are commonsense rules for both. First, plan to repair or replace it if it breaks. Second, note condition and care when you get it. Then return it with all accessories and parts intact, clean and with cords neatly wrapped (whether you received it that way, or not). Then carefully weigh the value of friendship. Those who professionally rent out tools understand that sometimes "things happen." Often, friends and neighbors don't. Sometimes it's better to wear out a rental tool than a friendship. And that's the On The House tip for today.
