Moving up (or down) means selling one home while buying another — the timing puzzle every second-time buyer faces. Sell-first vs. buy-first, contingencies, bridge options, and how your equity funds the move.
Escrow Analysis: Why Your Payment Changed on a Fixed-Rate Loan
“I have a fixed-rate mortgage. Why did my payment just go up?” It’s one of the most common calls a lender gets — and the answer is almost always the same: your escrow account got its annual checkup. Your interest rate didn’t move, and neither did your loan. What moved was the cost of your property taxes or homeowners insurance, and your payment adjusted to keep up. (This explainer is part of our Homeowner Library — the full set of guides for life after closing.)
What is an escrow account, exactly?
Most mortgage payments have two parts. The first is principal and interest — the actual loan. On a fixed-rate mortgage, this part never changes. The second is escrow: each month, you pay one-twelfth of your estimated annual property taxes and insurance, your servicer holds it, and when those bills come due, the servicer pays them for you.
It’s a convenience and a safeguard — the giant tax bill never lands on you all at once — but it runs on an estimate of costs that change every year.
What is an escrow analysis?
Once a year, your servicer audits the account: what actually got paid out for taxes and insurance, what’s projected for next year, and whether your monthly contribution still covers it. The result is your annual escrow statement, and it ends one of three ways:
- Shortage — taxes or insurance rose, the account came up short. Most common outcome.
- Surplus — costs came in lower; overages above a threshold are refunded to you.
- On target — nothing changes. (Enjoy it; it’s rare.)
Federal rules also allow the servicer to keep a cushion — up to two months of escrow payments — as a buffer, which factors into the math. (And if the statement arrives from a company you don’t recognize, your loan was probably transferred — normal, and covered in our guide to mortgage servicer transfers.)
Why do shortages happen so often?
Because both inputs mostly move one direction. Property taxes climb as home values are reassessed — in Colorado, county reassessments happen on a set cycle, and a strong market shows up in your tax bill. Homeowners insurance premiums have risen sharply for most owners in recent years. And in year one there’s a special catch: your original escrow setup was estimated at closing, sometimes off the home’s previous tax assessment — before the county caught up to your purchase price. That’s why the first escrow analysis after buying often carries the biggest jump.
What are my options when I get a shortage notice?
Typically two, and it’s worth doing the ten-second math:
- Pay the shortage in a lump sum. Your payment still rises a bit (next year’s costs are higher), but only by the true new monthly amount.
- Spread the shortage over 12 months. No cash today, but your payment rises more — new monthly cost plus one-twelfth of the catch-up — then drops after a year.
Neither is wrong. If cash is comfortable, the lump sum keeps the payment cleaner; if not, spreading it is exactly what the option exists for.
Can I do anything about the underlying costs?
Sometimes — and this is where homeowners leave money on the table:
- Challenge the tax number. If your county’s valuation looks high, you have a short appeal window. Guide here: how to appeal your Colorado property assessment.
- Reshop the insurance. Premiums vary widely for identical coverage, and switching insurers mid-loan is allowed. Guide here: reshopping homeowners insurance without losing coverage.
- Claim exemptions you’re owed. Colorado offers property-tax exemptions (seniors and disabled veterans, notably) that many eligible owners never file for.
- Check whether you still need PMI. Mortgage insurance rides along with the monthly payment too, and with enough equity it can come off entirely — here’s how to remove PMI.
Frequently asked questions
Why did my mortgage payment go up if my rate is fixed? The loan portion is fixed; the escrow portion isn’t. When property taxes or insurance rise, your annual escrow analysis adjusts the payment to cover them.
What’s an escrow shortage? The account paid out more for taxes/insurance than it collected. You can pay the gap as a lump sum or spread it over the next 12 months.
Why was my biggest payment jump in the first year? Closing estimates are sometimes based on the home’s previous tax assessment. Once the county reassesses at your purchase price, the first analysis catches everything up at once.
Can I remove escrow and pay taxes and insurance myself? Sometimes — many conventional loans allow an escrow waiver with enough equity and a good history, though some loan types require escrow. Ask before assuming either way.
