Appliance Lifespans and the Cost to Replace Image

Appliance Lifespans and Costs to Replace (A Worksheet)

Appliance lifespans can be a key factor in helping you budget for the house you’ve got your eye on — or the one you already have.  Here’s a question that’s easy to dismiss when you’re in love with a house and eager to make an offer: How long are its appliances and systems going to last?  Skip that question, and you might regret it.  Because if you end up spending three grand in the first year to replace broken-down appliances, you’re probably going to wish you’d offered $3,000 less.

Appliance Cost Worksheet

Simply add the year when an appliance was installed (scroll down for more on this), and the worksheet will tell you how much that house could cost you over the next 10 years — the typical time people stay in a home.  Then, with the help of an agent who knows the market, you decide if elderly appliances ought to be a negotiating item with the seller.

How to Find Out the Age of Appliances

Ask your agent to ask the seller. This is the most straightforward approach because homeowners usually remember major expenses like replacing a fridge.
•Consider the home’s age. A house less than 12 years old may still have all original appliances.
•Ask your inspector. If you’ve already made an offer, they’ll often have this information for you.
•Ask to see the  start_tip 116 property disclosure statement. end_tip  The property dosclosure statement could have the answers you need. Sellers are legally required to fess up about problems with the home or anything that comes with it.
•Scope it out. If a range is missing knobs or the oven bears years of burnt-on grease, chances are it’s in its twilight years, and you should probably plan to replace within the year.
•Find the serial number. Then visit for HVAC equipment and water heaters and for the rest to find the manufacture date. This is the most difficult but most accurate method if you want to be precise. But it’s up to the seller if they want to let you snoop around to find the serial numbers or to provide those numbers to you.
