You don't need it until you need it. That's what it's like when you have a home warranty. You pay the bill on a monthly or annual basis and it seems like it's a total waste of money until the HVAC, water heater, dishwasher, or something else goes out. It's far more easier to come up with the deductible of $75 or less than to suddenly have to come out of pocket of $2000 or more to make a repair.
If there's one bit of advice that will go a very long way it's for you to spend the money and get a home warranty. Trust me when I tell you one day you'll thank me.
