Key takeaways
- Most lenders collect property tax and insurance monthly into an escrow account and pay the bills for you.
- Property tax rates vary widely between states and counties, so the same house can cost hundreds more per month in one place than another.
- Taxes and insurance can rise every year even on a fixed-rate loan, so your escrow payment can change.
How location changes the same mortgage
Keep the loan identical — $320,000 at 6.75% for 30 years, principal and interest of $2,075.51 — and change only the property tax rate:
- 0.5% tax: $166.67 a month, PITI $2,392.18.
- 1.25% tax: $416.67 a month, PITI $2,642.18.
- 2.2% tax: $733.33 a month, PITI $2,958.85.
That is a difference of $566.67 a month for the same house price. Effective property tax rates in the US range from well under 1% in some states to around 2% in others, so check your county's actual rate rather than a national average.
What escrow means for you
With an escrow account, your servicer collects one-twelfth of the yearly tax and insurance bills each month and pays them when due. Once a year it reviews the account; if taxes or premiums rose, your monthly payment rises too, and a shortage may need to be repaid. Federal rules generally limit the extra cushion a servicer can hold to one-sixth of the yearly escrow payments.
Insurance is not one number
Homeowners insurance depends on the home's rebuild cost, location, deductible and claims history. Coastal and wildfire-prone areas can cost far more, and flood insurance is usually a separate policy. Get a real quote before you rely on the estimate.
Worked example
Monthly tax = $400,000 × 1.25% ÷ 12 = $416.67. Monthly insurance = $1,800 ÷ 12 = $150. Principal and interest on $320,000 at 6.75% for 30 years = $2,075.51. PITI = $2,642.18. With 20% down, no PMI is added.
Methodology and sources
Principal and interest use the standard amortization formula. Property tax is the yearly percentage you enter applied to the purchase price (your assessed value may differ). Insurance is your yearly premium divided by 12. PMI is added only below 20% down. Closing costs are not included.

Frequently asked questions
What does PITI stand for?
Principal, interest, taxes and insurance. It is the monthly amount most lenders collect, and it is used to judge whether you can afford the loan.
Are property taxes based on the purchase price?
Usually on the assessed value, which may be lower or higher than what you pay and may be reassessed after a sale. Using the purchase price is a reasonable estimate; check your county's rules.
Why did my mortgage payment go up on a fixed-rate loan?
The principal and interest part is fixed, but the escrow part changes when property taxes or insurance premiums change.
Can I pay taxes and insurance myself?
Some lenders allow you to waive escrow, often only with a larger down payment and sometimes for a fee. You then pay the bills directly when due.
