What's Actually in Your Monthly Mortgage Payment? PITI Explained (California 2026)
Short answer: your monthly mortgage payment is made up of four parts known as PITI — Principal, Interest, Taxes, and Insurance — plus PMI and HOA dues if they apply to you. The principal and interest pay down your loan; the taxes and insurance are collected into an escrow account and paid on your behalf. In California, property taxes and the rising cost of homeowners insurance make the escrow portion larger than most first-time buyers expect, so understanding each piece keeps you from being blindsided at closing.
P & I: Principal and Interest
This is the loan portion. Principal reduces your balance; interest is the cost of borrowing. On a fixed-rate conventional loan, this part never changes. Early on, most of your payment goes to interest and only a little to principal — that's normal amortization. See how mortgage rates work for why the rate drives this number, and model it in our calculator.
T: Property Taxes
Your lender collects roughly 1/12 of your annual property tax each month and holds it in escrow. In California, the effective rate runs about 1.1%–1.3% of assessed value, and new buyers are reassessed at purchase price — so this line can be substantial. We break down exactly how this works in Proposition 19 and California property taxes.
I: Homeowners Insurance
Also collected monthly into escrow. This is the line that's been climbing fastest in California — the insurance availability and cost crisis we covered in how the insurance crisis affects your mortgage has pushed premiums up and, in some areas, made coverage hard to find. Get a real insurance quote early, because it directly affects your monthly payment and your loan approval.
The two extras: PMI and HOA
If you put less than 20% down on a conventional loan, PMI is added until you reach 20% equity. If your home is in a community with a homeowners association, HOA dues are a separate monthly cost (usually paid directly to the HOA, not through escrow) — but lenders count it in your debt-to-income ratio. In some California condo markets, HOA dues can rival the tax line, so always ask.
Why your payment can change over time
Even with a fixed rate, your total payment can move because taxes and insurance change. If your property tax rises or your insurance premium jumps, your escrow shortfall is spread across the next year and your payment goes up. This is why two buyers with the same rate and loan amount can have very different payments — and why budgeting for the full PITI, not just principal and interest, matters. Before you shop, get pre-approved so you see your real all-in number; see our pre-approval guide.

Worked example: a full California PITI payment
An illustrative $900,000 home with 20% down ($720,000 loan) on a 30-year fixed at an example 6.5% rate (not a quote):
| Component | Monthly |
|---|---|
| Principal & interest | ~$4,551 |
| Property tax (~1.15% of price) | ~$863 |
| Homeowners insurance (example $3,000/yr) | ~$250 |
| PMI | $0 with 20% down |
| Total PITI | ~$5,664 |
Taxes and insurance add about $1,100 a month on top of principal and interest here. Add HOA dues if the home has them. Rates change daily, so run your own numbers in our payment calculator.
Mello-Roos and special assessments
Many newer California communities sit inside a Community Facilities District, often called Mello-Roos. These special taxes fund roads, schools and parks, and they appear on your property tax bill on top of the base 1% rate.
- They can add hundreds of dollars a month in some newer developments.
- They are usually paid through escrow with your regular taxes.
- Lenders count them in your debt-to-income ratio.
- Many have a set end date, but some maintenance taxes continue indefinitely. The district disclosure shows which.
Ask for the full tax bill, not just the assessed value, before you make an offer.
How lenders use PITI to qualify you
Your full PITI plus HOA is the housing expense in your debt-to-income ratio. Add car payments, student loans and card minimums, then divide by gross monthly income. Many programs top out around the mid-40s to about 50% total DTI, though limits vary by program and file.
This is why a low insurance quote or a home without Mello-Roos can raise the price you qualify for. Rates change daily, so for an accurate quote call 949-379-5320 (Newport Beach) or 310-759-4757 (Marina del Rey).
More questions
Is Mello-Roos included in my mortgage payment?
Usually yes. Mello-Roos special taxes are part of the property tax bill, so they are typically collected through your escrow account along with regular property taxes.
Can I pay my property taxes and insurance myself instead of through escrow?
Sometimes. Conventional loans may allow you to waive escrow, typically with at least 20% equity and sometimes a pricing cost. FHA loans require an escrow account.
