The True Cost of Homeownership: Understanding PITI, Property Taxes, Insurance, and Impounds
One of the biggest surprises for many first-time buyers is discovering that a mortgage payment is much more than simply repaying a loan.
When lenders discuss affordability, they typically focus on a figure known as PITI. Understanding what PITI means—and what other expenses come with homeownership—can help you budget more accurately and avoid surprises after moving in.
What Is PITI?
PITI stands for:
P – Principal
I – Interest
T – Taxes
I – Insurance
Together, these four components make up what most people consider their monthly housing payment.
Principal
Principal is the portion of your payment that reduces the amount you owe on your mortgage.
For example, if you borrow $1,000,000 and make a payment that reduces the balance by $500, your new loan balance becomes $999,500.
Interest
Interest is the fee charged by the lender for borrowing money.
In the early years of a mortgage, most of your payment goes toward interest. As time passes, more of each payment is applied to principal.
What Is an Amortized Mortgage?
Most home loans are fully amortized.
This means each monthly payment is designed to gradually pay off both principal and interest over a predetermined period, usually 30 years.
One of the most surprising facts about mortgages is that the payment stays relatively constant while the allocation changes.
In the beginning:
- More goes toward interest
- Less goes toward principal
Later:
- More goes toward principal
- Less goes toward interest
- In a 30-year loan, the first payment goes almost entirely to interest, and the last payment in year 30 goes entirely to the principal. At approximately year 15, half of your mortgage payment goes towards interest, and the other half towards principal.
Property Taxes
Property taxes are generally based on the assessed value of the property.
In California, buyers typically use approximately 1.0225% of the purchase price per year as a budgeting estimate.
For example:
Purchase Price: $1,500,000
Estimated Property Taxes:
$1,500,000 × 1.0225% = $18,375 annually
Monthly Property Taxes:
$18,375 ÷ 12 = approximately $1,531.25 per month
Actual tax rates vary by location and voter-approved assessments.
Homeowners Insurance
Lenders require homeowners’ insurance to protect the property securing the loan.
Insurance premiums vary depending on:
- Property value
- Location
- Construction type
- Coverage levels
- Deductibles
Many Peninsula homeowners pay anywhere from $1,500 to $4,000 or more annually, depending on the property.
What Are Impounds?
Some lenders require an impound account, for loans with less than a 20% downpayment (also called an escrow account).
Rather than paying property taxes and insurance directly, you pay a portion of those expenses each month along with your mortgage payment.
The lender collects:
- Principal
- Interest
- Property Taxes
- Insurance
The lender then pays the tax collector and insurance company when those bills become due.
Impounds help ensure that taxes and insurance are paid on time and prevent homeowners from facing large lump-sum payments.
Are HOA Fees Included in PITI?
No.
Homeowners Association (HOA) dues are generally not included in PITI.
If you’re purchasing a condominium, townhouse, or planned development, HOA fees should be added to your monthly housing budget.
Don’t Forget Maintenance Costs
Many first-time buyers focus entirely on their mortgage payment and overlook maintenance.
A good rule of thumb is to budget approximately .05% of the home’s value annually for repairs and maintenance.
A $1,500,000 home could require:
$7,500 per year
or roughly
$625 per month
for ongoing maintenance and future repairs.
Some years may require very little, while others may involve major expenses such as a roof replacement, furnace, water heater, or exterior painting.
The Bottom Line
When evaluating affordability, don’t focus solely on the mortgage payment.
Consider the entire cost of ownership:
- Principal
- Interest
- Property Taxes
- Homeowners Insurance
- HOA Dues
- Utilities
- Maintenance and Repairs
The goal isn’t simply to buy the most expensive home you qualify for.
The goal is to buy a home you can comfortably enjoy for years to come.
That’s why understanding the true cost of homeownership is one of the smartest things a buyer can do before making an offer.
