PITI Explained: What’s Actually in Your Monthly Mortgage Payment

When first-time buyers in DC, Maryland, and Virginia start running the numbers on a home, they often make the same mistake: they look at a mortgage calculator, see the principal and interest payment, and assume that is what they will pay every month. It is not. Your real monthly housing payment is almost always higher, because it includes property taxes and homeowners insurance — and often mortgage insurance and HOA dues on top. The industry term for the full payment is PITI, and understanding it before you start house hunting is the difference between a budget you can live with and a payment that stretches you thin.

What PITI Stands For

PITI is an acronym for the four components that make up most monthly mortgage payments:

Your lender collects all four components in a single monthly payment. The principal and interest go to the lender (or loan servicer). The tax and insurance portions go into an escrow account, and the lender pays your county tax bill and insurance premium on your behalf when they come due. This is called escrowing, and most loans with less than 20% down require it.

Principal and Interest (P&I)

This is the core of your mortgage payment — the money that services the loan itself. On a $450,000 loan at 6.75% over 30 years, the P&I payment is about $2,919 per month. In the early years, the vast majority of that goes to interest. On your first payment, roughly $2,531 is interest and only $388 is principal. Over time, the ratio flips — by year 20, more than half goes to principal. This is called amortization.

On a fixed-rate loan, the total P&I payment never changes. Only the split between principal and interest shifts. On an adjustable-rate mortgage, the P&I payment can change when the rate adjusts.

Property Taxes

Property taxes vary dramatically across the DMV, and they are a bigger line item than most buyers expect:

• DC: Effective rate around 0.46% — on a $600,000 home, roughly $2,760/year ($230/mo)
• Maryland: Varies by county; effective rates range from 0.87% to 1.12% — on a $500,000 home in Montgomery County, roughly $5,000/year ($417/mo)
• Virginia: Varies by locality; effective rates range from 0.80% to 1.15% — on a $500,000 home in Fairfax County, roughly $5,700/year ($475/mo)

Your lender estimates your tax bill based on the current assessment and the seller's most recent tax bill, then divides it by 12 and adds it to your monthly payment. If the tax bill changes — because of a reassessment after purchase, a rate change, or a special assessment — your escrow payment adjusts, and your total monthly payment goes up or down.

Homeowners Insurance

Lenders require you to carry hazard insurance to protect their collateral (your home) against fire, wind, theft, and other covered perils. In the DC metro, a standard policy on a $500,000 home typically runs $1,000–$2,000 per year, depending on the home's age, construction, deductible, and whether you need additional coverage like flood insurance. If your property is in a FEMA-designated flood zone — common in parts of Alexandria, Arlington near the Potomac, and low-lying areas of Maryland — your lender will require a separate flood insurance policy, which adds several hundred dollars per year.

The Fifth Letter: M for Mortgage Insurance

If you put less than 20% down on a conventional loan, or if you have an FHA loan, your payment also includes mortgage insurance. This is a separate premium that protects the lender (not you) if you default. Conventional loans call it Private Mortgage Insurance (PMI); FHA calls it the Mortgage Insurance Premium (MIP). PMI on a conventional loan can be cancelled once your loan-to-value reaches 80%, but FHA MIP is more difficult to remove — it stays for the life of the loan unless you put 10% or more down (in which case it drops off after 11 years). On a $450,000 loan with 5% down, PMI typically adds $150–$250 per month.

Some lenders offer lender-paid mortgage insurance (LPMI), where the lender pays the premium in exchange for a slightly higher interest rate. This can lower your total monthly payment but removes the ability to cancel the insurance separately once you reach 80% LTV. We compare both options for every client to see which costs less over the expected time in the home.

HOA Dues: Not in PITI, But Still Due

If you buy a condo or a home in a homeowners association, your monthly HOA dues are a separate payment sent directly to the association — not part of your mortgage payment. But lenders include HOA dues in your debt-to-income calculation, and they can materially affect how much you qualify for. A $400/month HOA payment can reduce your purchase budget by $60,000–$80,000 depending on your rate and DTI limit. Always factor HOA dues into your total housing cost, even though they are not technically part of PITI.

Why PITI Matters for Qualifying

Lenders do not qualify you on P&I alone. They qualify you on the full PITI payment (plus HOA dues if applicable) as a percentage of your gross monthly income — this is your debt-to-income (DTI) ratio. Most conventional loans cap your total DTI (PITI plus all other monthly debts like car payments, student loans, credit cards) at 45–50%. FHA allows up to 56.99% in some cases. If you only budgeted for P&I, the tax and insurance components can push your DTI over the limit and reduce your max purchase price by tens of thousands of dollars.

Plan for the Full Payment, Not Just P&I

The single most common budgeting mistake we see from first-time buyers in the DC metro is falling in love with a home based on the P&I payment, then discovering the full PITI is $500–$800 higher than expected. Property taxes in Maryland and Virginia are significant, and mortgage insurance on low-down-payment loans adds up. We walk every client through a full PITI breakdown — taxes, insurance, PMI, and HOA — for the specific property and loan program before they make an offer.
