Taxes & Insurance Not Included

The most common budgeting mistake in homebuying is treating the calculator's output as the monthly cost. Property taxes and insurance are not small add-ons, they are not fixed, and unlike your P&I they will be different in five years.

What escrow actually is

Most lenders collect taxes and insurance along with your loan payment and hold them in an escrow account, paying the bills on your behalf when they come due.

So the amount leaving your bank account each month is P&I plus one-twelfth of your annual tax bill plus one-twelfth of your insurance premium. That combined figure is usually called PITI.

On a $340,000 loan with $2,149 of P&I, a $6,000 annual tax bill, and $1,800 of insurance, the escrowed payment is about $2,799.

The parts that change without warning

Property taxes rise as assessed values rise and as local rates change. A reassessment after a purchase frequently increases the bill, sometimes by several hundred dollars a year.

Insurance premiums have risen sharply in many regions, with double-digit annual increases in areas exposed to storms, wildfire, or hail. A $1,500 policy becoming a $2,400 policy over three years is not unusual.

When those bills rise, your escrow payment rises with them. The letter announcing a $180 monthly increase arrives with no negotiation available.

Escrow shortages and why they sting

The lender estimates next year's bills and collects accordingly. When the actual bills come in higher, the account runs short.

You then get two things at once: a request for the shortfall, either as a lump sum or spread over twelve months, and a higher ongoing payment to cover the new estimate.

Budgeting a small buffer above your escrow payment absorbs this. Households that budget to the exact dollar are the ones for whom the annual escrow analysis is a crisis.

You can challenge some of these numbers

Property assessments can be appealed, and the process is often more straightforward than people expect. A successful appeal lowers your tax bill for years, not just once.

Insurance is fully shoppable. Getting three quotes at renewal regularly moves the annual premium by several hundred dollars for identical coverage.

Raising your deductible lowers the premium meaningfully, which is a reasonable trade once you have an emergency fund that could absorb the higher deductible.

None of this applies to the mortgage principal and interest, which are locked in. The escrow side is the part of your housing cost you retain some control over.

Getting real numbers before you buy

Look up the property's actual tax bill on the county assessor website rather than trusting the listing. Then check whether your purchase price will trigger a reassessment, because the current owner's bill may be well below what yours will be.

Get an actual insurance quote for the specific address before making an offer. Roof age, claim history, and distance from a fire station move premiums enormously, and a generic estimate can be off by half.

Add both to the P&I from this calculator, then add maintenance. That total is the number to test against your income.

What you can actually push back on

Property assessments can be appealed. If comparable homes nearby are assessed well below yours, filing an appeal costs little and occasionally reduces the bill by hundreds a year.

Insurance should be reshopped every two or three years rather than renewed on autopilot. Premiums drift upward and the same coverage from another carrier is frequently 15% to 25% cheaper.

Raising your deductible from $1,000 to $2,500 lowers the premium meaningfully, which works well if you keep an emergency fund and poorly if you do not.
