As a realtor and investor, one of the questions I get the most is how long parts of the house will last. Obviously, how well a homeowner / tenant takes care of things plays a huge part, but I have started to see some trends and averages. I’ve listed below some of the averages I’ve found, but always open to hearing about others’ experiences or tips to make things last longer!

Exterior

• Roof: 20-30 years
• Windows: 15-25 years
• Exterior paint: 10 years
• Gutters: 20-40 years

Systems:

• HVAC: 10-15 years
• Electric switches/sockets: 15-25 years
• Water heater: 10-15 years
• Furnace: 15-20 years

Kitchen

• Kitchen sink: 20 years
• Fridge: 6-15 years
• Microwave: 6-9 years
• Stove: 10-15 years
• Dishwasher: 8-10 years

Bathroom

• Toilets: 50 years
• Tub/Shower: 10-15 years

20-30 year roofs sounds like a dream. I live in Oklahoma and we'd be doing good to have a quality roof last 15 years. If you have a roof over 10 years old, it's probably going to have to be replaced prior to a retail sale. 

Wow, this is really helpful! Thanks Theo!

@Cassi Justiz agreed! Especially when we go back to more of a buyers market i think that we will see that request becoming more frequent in orders.
