What Should I Do in the First 30 Days After Buying My First Home?
The short answer
What should you do in the first 30 days after buying your first home in Orange County? Save your closing documents, update your address with the DMV and the Post Office, watch for your Homeowners' Exemption application, and set money aside for a supplemental property tax bill. Then confirm who services your loan, review your insurance, and make a short list of home projects. These steps protect your money and keep surprises small.
Why Do the First 30 Days Matter?
Closing day feels like the finish line. A few of the most important steps for new owners happen right after it, and some come with deadlines.

I want first-time buyers to leave escrow with a simple plan for the weeks ahead, so nothing important slips while they're unpacking.
What Paperwork Should I Keep?
Make one folder, paper or digital, for:
- Your final Closing Disclosure and purchase contract
- Your loan documents and first payment letter
- Your inspection reports and any repair receipts
- Your homeowners insurance policy
- Your recorded deed when it arrives
The Orange County Clerk-Recorder, working with the District Attorney, also mails free Property Fraud Prevention Courtesy Notices when certain documents, such as grant deeds or quitclaim deeds, are recorded on a property. No sign-up is needed. If you ever receive one for a document you don't recognize, follow the instructions on the notice right away.
What Do I Need to Do About Property Taxes?
File for the Homeowners' Exemption. The Orange County Assessor says the exemption reduces your assessed value by $7,000 if the home is your principal residence. The Assessor's FAQ says new owners usually receive a pre-filled application within about 90 days of the deed recording. To get the full exemption, file by 5:00 p.m. on February 15. Filing on or before December 10 can still get 80%, or $5,600.
Plan for a supplemental bill. The Orange County Treasurer-Tax Collector explains that new owners usually receive a supplemental property tax bill after a purchase, based on the difference between the old and new assessed value. The Treasurer-Tax Collector also notes that mortgage companies don't usually pay supplemental bills, even with an impound account. Watch your mail and set aside money for it.
My article on how property taxes are set when you buy explains the full picture.
Who Needs My New Address?
- The DMV. The California DMV asks you to report a change of address within 10 days of moving, for your license and vehicle records.
- The Post Office. The USPS lets you submit a change of address online so your mail follows you.
- Everyone else. Your bank, employer, insurance companies, voter registration and any subscriptions.
What Should I Know About My Mortgage Payments?
Your first payment date is on your loan documents. Set a reminder or enroll in autopay once you've confirmed the details with your servicer.
Don't be surprised if your loan moves to a new servicer. The CFPB explains that you should get a notice when servicing transfers, and that for 60 days after the transfer, your new servicer can't charge a late fee or treat a payment as late if you sent it on time to your previous servicer. Read every notice carefully, and confirm any new payment address by calling the number on your official statement, not a number in an email.
Fraud attempts don't stop at closing. My article on protecting your money from wire fraud covers the warning signs.
Should I Review My Insurance?
Yes. Read your homeowners policy so you know what it covers and what the deductible is. The California Department of Insurance explains that homeowners policies generally don't cover earthquake damage, and that earthquake coverage is a separate decision. Your insurer must offer it, and many buyers look at it in their first month.
What About Home Projects?
Start with the notes from your inspection. My article on what to expect at your first home inspection explains how to read the report. Many new owners also change the locks, test the smoke and carbon monoxide alarms, and learn where the water and gas shutoffs are.
Before any remodel, addition or major repair, check with the city about permits for your specific property. Small projects done well beat a big project rushed in the first month.

Frequently asked questions
When should I file the Homeowners' Exemption in Orange County?
Watch for the pre-filled application from the Orange County Assessor, usually within about 90 days of recording. File by February 15 for the full $7,000 exemption. Filing by December 10 still qualifies for 80%.
Will my impound account pay the supplemental tax bill?
Usually not. The Orange County Treasurer-Tax Collector says mortgage companies don't usually pay supplemental bills, so plan to pay it yourself.
How soon do I need to update my address with the DMV?
The California DMV asks you to report a change of address within 10 days of moving.
What if a letter says my loan has a new servicer?
That's common. Read the notice, confirm it through your official mortgage statement, and keep making payments on time. The CFPB explains the 60-day protection for payments sent to your old servicer.
Do I need earthquake insurance?
It's your decision. The California Department of Insurance explains that standard homeowners policies generally exclude earthquake damage, so ask your agent or insurer about a separate policy.
