First-Year Budget After Closing on a Colorado Home

The first year in a Colorado home costs $6,000 to $12,000 beyond the mortgage payment on a $500,000 to $700,000 house, and most of it lands on dates the lender's estimate never showed: the sprinkler blowout in October, the escrow analysis in the spring, the hail deductible the first June a storm crosses the Front Range. The table below is the budget the Kenna Real Estate Group at Keller Williams DTC hands buyers at closing, line by line with Denver metro prices.

The hidden costs of buying your first home post covers the money spent before the keys. This page starts the day after. Resources such as Builders Innovation Group cover how insurance and long-term property protection fit into the cost of owning; the numbers here are the Colorado version.

The first-year budget table for a Colorado home

How are Colorado property taxes paid, and why does the escrow go up?

Colorado bills property tax in arrears. The tax for 2026 arrives from the county treasurer in January 2027, and the owner pays half by the last day of February and half by June 15, or the whole bill by April 30. When a lender escrows, the monthly payment collects one-twelfth of the estimated bill, and the lender sets that estimate from the seller's most recent bill.

That estimate is the trap. Colorado counties reappraise every two years, in odd-numbered years, using sales through June 30 of the prior even year. A home bought in a rising market escrows on the old value, then the new assessment arrives and the servicer's first escrow analysis finds a shortage. The servicer spreads the shortage over the next 12 months and raises the monthly payment to the new level, so a $600 shortage becomes a $50 bump plus the higher ongoing amount. On new construction the gap is larger: the seller's bill was for a vacant lot, and the first full-year bill on the finished house adds $200 to $400 a month.

Effective rates in established Denver metro neighborhoods run 0.5 to 0.7 percent of market value, and 0.9 to 1.2 percent in newer subdivisions inside a metro district. The Denver property taxes guide shows how the mill levy and assessment rate produce the bill, and the metro district tax guide explains the second line on the statement. Owners 65 and older who have owned and lived in the home for 10 years qualify for the Colorado senior exemption on part of the value; apply through the county assessor by July 15.

What is a hail deductible and how much cash does it need?

Front Range insurers moved most policies to a separate wind and hail deductible of 1 to 2 percent of the dwelling coverage, and some carriers write 5 percent. On a policy with $500,000 of dwelling coverage that is $5,000 to $10,000 out of pocket before the insurer pays a dime toward a new roof. Hail season runs May to September, and the storms that cross Aurora, Centennial, Parker and Castle Rock take out whole neighborhoods of roofs in one afternoon.

• Read the declarations page for the wind/hail line, not the all-perils deductible.
• Hold the deductible in cash from the first hail season you own the house.
• Ask about Class 4 shingles: impact-resistant roofs earn premium discounts with most Colorado carriers, and a roof replaced after a claim is the time to upgrade.

Premiums themselves run $2,000 to $4,500 a year for a $500,000 to $700,000 Front Range home, more in the wildfire zones of the foothills. The post on Colorado hail and roof costs compares roof types by expected life.

How much does radon mitigation cost in the Denver metro?

Colorado sits in the EPA's highest radon zone, and a large share of Front Range homes test above the 4.0 pCi/L action level. If the inspection test came back high and the seller did not mitigate, the system costs $1,000 to $2,500 installed: a sealed sump or slab penetration, PVC pipe and a fan that vents above the roofline. The fan draws $5 to $10 a month in electricity and lasts about 10 years; a replacement fan runs $300 to $500. Retest every two years with a $15 to $30 charcoal kit. Full detail is in the Denver radon testing and mitigation guide.

When is the sprinkler blowout and what does the yard cost?

The first hard freeze on the Front Range lands in mid-October in most years, and a sprinkler system with water in the lines splits the backflow preventer, a $300 to $600 repair. A blowout with compressed air costs $60 to $120 and books out two weeks ahead in October. Spring startup in late April costs $80 to $150, plus $100 or more if a head or valve failed over the winter. The post on backflow preventers and sprinkler blowout in Colorado shows the steps.

Denver Water and the suburban districts bill on tiered rates, and a lawn on a 7,000-square-foot lot pushes a July bill to $100 to $200.

What does furnace service cost in Denver and when?

Front Range furnaces run from October to April, and a $100 to $200 fall tune-up catches the cracked heat exchanger or failing igniter before the first cold week when every HVAC company is booked. A gas furnace lasts 15 to 20 years at altitude; replacement runs $5,000 to $10,000, and Xcel Energy rebates apply to high-efficiency units. Change the filter every 60 to 90 days, more during wildfire smoke weeks.

How many times a year do Front Range gutters need cleaning?

Twice a year on a lot with cottonwoods or mature ash: once after the June cotton drop and once after the November leaf drop. Each visit costs $150 to $300 on a two-story house. Clogged gutters on a Colorado roof turn into ice dams in a freeze-thaw week, and ice dams push meltwater under the shingles and into the wall.

Why do Colorado basements need window well covers?

Nearly every Front Range basement has egress window wells, and an open well fills with snow, leaves and hail runoff that seeps through the window frame. Polycarbonate covers cost $100 to $300 per well, installed, and a house with three wells is a $300 to $900 line item in the first fall. Check the drain gravel at the bottom of each well at the same time; a well with no drain floods the finished basement in a spring storm.

What snow tools does a Denver homeowner need?

Denver gives residents 24 hours after snow stops to clear the public sidewalk in front of the house, and most Front Range cities enforce the same window with a warning and then a fine. A steel-edged shovel, a 50-pound bag of ice melt rated for concrete, and a roof rake for the first heavy wet snow total $100 to $250. A two-stage snow blower runs $500 to $1,500 and pays for itself on a corner lot in Arvada or a long driveway in Castle Rock. Skip rock salt on concrete less than a year old; it spalls the surface.

What do HOA and metro district fees add in the Denver suburbs?

Single-family HOAs in the metro charge $30 to $150 a month and bill monthly, quarterly or annually. Highlands Ranch bills the HRCA assessment quarterly and it covers the four recreation centers. Condo and townhome dues run $250 to $600 a month and include the master insurance policy, water and exterior maintenance, and a special assessment for a roof or a parking structure lands on top with 30 to 90 days' notice.

A metro district is not an HOA. It is a taxing district that repaid the developer's roads and pipes with bonds, and its mill levy sits on the county tax bill for 20 to 40 years. On a $600,000 home it adds $1,500 to $3,500 a year, escrowed with the rest of the tax. Both numbers are in the documents the seller delivers under the Colorado contract; the Denver HOA rules and fees guide lists what to read.

How much should a Colorado homeowner reserve for appliances and the roof?

Set aside 1 percent of the home's value per year, so $500 a month on a $600,000 house, in a separate account. That fund covers the water heater ($1,500 to $3,000 installed), the dishwasher and refrigerator ($800 to $2,500 each), and the roof. An asphalt roof on the Front Range lasts 15 to 25 years between hail claims, and a replacement on a 2,000-square-foot house costs $12,000 to $25,000; the deductible comes out of the same fund.

What do utilities cost the first year?

Xcel Energy gas and electric on a 2,000-square-foot house average $150 to $250 a month across the year, with January gas bills double the July number. Water and sewer run $60 to $120 a month. Denver trash is billed by cart size on the city account; suburbs pay a private hauler $25 to $45 a month or fold it into HOA dues. The Denver utility providers and costs guide has the provider list by city.

How big an emergency fund does a Colorado homeowner need?

Three items set the floor: the hail deductible, one furnace or water heater replacement, and two months of the full house payment. On a $600,000 Front Range home that is $15,000 to $20,000, held separately from the appliance reserve. A smaller down payment with a funded reserve costs less than a roof on a credit card.
