New Homeowner Checklist: What to Document Before You Need It

Nobody warns you about this part of homeownership.

The inspection is done. The keys are yours. And somewhere between the moving boxes and the paint samples, you become the single point of failure for everything in that house. The plumber's number. The warranty on the water heater. The name of the previous owners' HVAC company. The year the roof was last replaced.

Nobody gives you a file for any of it. You're just supposed to know.

Here's what to document in your first 30 days — before you need it in an emergency.

1. Every vendor and contractor who touches your house

Start a list the moment you move in. Every service call, every repair, every estimate — log the company name, the technician's name if you got it, the phone number, and what they did.

This list will save you hundreds of dollars. When your furnace acts up in January, you won't be Googling "HVAC company near me" and hoping for the best. You'll call the person who already knows your system.

Log for each vendor:

• Company name and phone number
• Service category (plumbing, HVAC, electrical, pest control, etc.)
• Date of last service
• Notes on what was done

2. Every appliance with a warranty

Pull out the manuals. Find the receipts if the previous owners left any. For appliances you buy new, register them immediately — most warranties require it.

What to capture for each appliance:

• Make, model, and serial number
• Purchase date and purchase price
• Warranty expiration date
• Where the manual is (or a photo of it)

Appliances to prioritize: refrigerator, washer/dryer, dishwasher, HVAC system, water heater, garage door opener.

3. Your home systems — the ones behind the walls

These are the things you'll need to explain to a technician the first time something goes wrong.

Document:

• Age of the roof (ask your realtor or inspector if you don't know)
• Age and type of water heater
• HVAC system age, brand, and last service date
• Filter sizes for HVAC and any air purifiers
• Location of the main water shutoff
• Location of the electrical panel — and which breaker controls what
• Location of the gas shutoff

The filter sizes alone will pay for the ten minutes this takes. You'll be standing in a hardware store someday, and you'll know exactly what to buy.

4. The paperwork from closing

Your closing documents contain information you'll need for years: the legal description of the property, survey documents, title insurance policy, deed of trust or mortgage documents, and HOA documents if applicable.

Most of it lives in a folder you'll never open again — until you need it desperately. Scan it or photograph it. Store it somewhere you can find it in three years.

5. Home improvement history

If the previous owners left any records of work done on the house, keep them. Permits pulled. Contractors used. Improvements made.

When you sell this house someday, a documented history of maintenance and improvements adds real value. When you need to match the paint color in the guest room, you'll have it.

Start a log now for every improvement you make: what was done, who did it, when, and how much it cost.

6. Insurance information

Home insurance policy number, your agent's contact, and the claims line. Keep this somewhere your partner can also find it — not just in your email inbox.

Why this matters more than you think

The average household has 12 active service vendors and 8 appliances under warranty. One person knows all of it. When that person isn't available — traveling, sick, dealing with something else — the other person is starting from zero in a moment of stress.

This isn't just an organization project. It's risk management.

The good news: you only have to build this once. If you document as you go — every service call, every appliance purchase, every repair — you'll never have to reconstruct it.
