📌 Key Takeaways
- Beyond your down payment, plan for closing costs of roughly 2–5% of the purchase price.
- The costs that surprise buyers most are recurring: supplemental property tax bills, HOA dues, Mello-Roos, and insurance.
- Your 1% cash-back rebate is real money that can offset many of these costs at closing.
The sticker price and the down payment are only part of what it costs to buy in California. Here are the fees that catch buyers off guard — and how to plan for them.
One-time closing costs
At close of escrow you'll pay a bundle of fees on top of your down payment, generally totaling in the low single-digit percentages of the purchase price. These include loan origination charges, the appraisal, escrow and title fees, recording fees, and prepaid items like the first chunk of property tax and a year of homeowners insurance. Your lender provides a Loan Estimate early on so you can see these in writing.
The recurring costs that surprise people
Supplemental property tax bill
This is the classic California surprise. After you buy, the county reassesses the home at your purchase price and sends a one-time supplemental bill for the difference — often months after closing, when buyers have forgotten to budget for it.
HOA dues
Condos and many planned communities charge monthly homeowners-association dues that can range from modest to substantial, and they can rise over time or hit you with special assessments.
Mello-Roos
Newer master-planned communities, common in parts of Orange County, often carry Mello-Roos special taxes that fund local infrastructure. These appear on your property tax bill and can add meaningfully to your annual cost.
Insurance
Beyond standard homeowners insurance, some SoCal areas require or strongly suggest additional coverage for fire or earthquake risk, which adds to your monthly housing cost.
Inspections, moving, and the move-in
Don't forget the smaller line items: general and specialty inspections, movers, immediate repairs or upgrades, and setting up utilities. Individually small, together they add up.
How to budget — and how the rebate helps
The simplest rule: budget your down payment plus another 2–5% for closing costs, then set aside a cushion for the supplemental tax bill and first-year ownership. This is exactly where Portfolio Home Realty's 1% rebate earns its keep — it's cash back at closing that can directly offset these costs instead of coming out of your savings.

When you buy, the county reassesses the property at your purchase price and bills you for the difference between the old and new assessed value. It usually arrives months after closing as a separate, one-time bill — so set money aside for it.
Some are. Lender and third-party fees can sometimes be shopped or reduced, and you can ask the seller for a closing-cost credit as part of your offer. Your agent can help structure this.
A good rule of thumb is an extra 2–5% of the purchase price for closing costs, plus a cushion for the supplemental tax bill, insurance, and early repairs. Your 1% rebate can offset a chunk of it.
