Buying Before You Sell in Colorado: The Whole Picture
Program and regulatory figures verified September 19, 2026. Details change; confirm your scenario with us.
Everything a Colorado move-up or move-down buyer needs to decide the order, in the order the decisions actually get made.
Step one: find out whether a tax benefit is leaving with you
In most states this is not the first question. In Colorado right now it is, because the answer changed in June and most published material has not caught up.
If you are 65 or older and have owned and occupied your current home for at least 10 consecutive years, you may be receiving the senior exemption on 50% of the first $200,000 of actual value. If you move, that ends, and a new 10-year period begins on the next house.
Until recently there was a bridge. SB24-111 created a qualified-senior primary residence classification for tax years 2025 and 2026. SB26-116 ended it for tax years beginning on or after January 1, 2027, and capped applications through July 15, 2026. Both dates have passed. Detail on the repeal page.
If you are not in that category, skip ahead; the rest of the state's rules are ordinary. If you are, this is the largest number in your move and it belongs at the front of the conversation.
Step two: the honest time on market, for your Colorado
For the month ending August 2026 the typical US home went pending in 53 days. Colorado's answer depends entirely on where the departing house is.
Front Range: Greeley 45, Denver 48, Colorado Springs 50, Fort Collins 50, Boulder 52. At or better than the national figure.
Elsewhere: Grand Junction 60, Durango 61, Pueblo 69, Breckenridge 73, Montrose 74, Edwards 81, Glenwood Springs 86, Steamboat Springs 93. Steamboat's figure rose 31 days over the year.
Days to pending is list to pending, so add your closing period. The full table is on the market page.
Step three: the two-payment test, with the right tax line
Can documented income carry both housing payments at once? That is the whole test. What Colorado adds is that the new home's tax line has to be modelled without an exemption you are no longer carrying, and using the correct split rates: 6.8% for non-school local levies and 7.05% for school levies, with 10% of the first $700,000 of actual value subtracted before the local rate applies.
Estimating Colorado property tax as a flat percentage of purchase price gets this wrong in both directions, because the split rate and the subtraction do not behave like a single rate.
Step four: which structure, given the overlap you actually face
A short Front Range overlap supports structures that cost less and assume less: carrying both payments, or term financing sized to a defined gap. A long mountain overlap argues for a low monthly carrying obligation, or for renting the departing home and removing the timing question entirely.
Colorado is unusually friendly to the borrowing route because there is no mortgage recording tax and the documentary fee attaches to deeds rather than deeds of trust. Comparison on line versus term.
Step five: if you might rent the departing home
Two rules apply, one state and one federal, and they pull in different directions.
HB24-1098 requires cause to end a residential tenancy in Colorado and removes lease expiration alone as a ground. Intending to sell is an enumerated no-fault cause, generally on 90 days written notice. So the house is harder to get back than in a state like Florida, where a month-to-month tenancy ends on 30 days notice.
Federally, for applications dated on or after November 1, 2026, Fannie Mae B3-3.8-05 requires market rents rather than a lease, states that lease agreements are not permitted for any departing residence, and treats a positive figure as an offset against that property's own payment rather than as qualifying income. Six months of PITIA reserves apply where property management experience is under 12 months. See the rental conversion page.
Step six: the loan limit question, which is live here
Twenty of Colorado's 64 counties exceed the 2026 baseline of $832,750. Eagle County sits at the national ceiling of $1,249,125; Garfield and Pitkin at $1,209,750; Lake and Summit at $1,092,500; Moffat and Routt at $1,089,050; San Miguel at $994,750; Grand at $883,200; Boulder at $879,750; and the ten Denver metro counties at $862,500.
Above the applicable limit the financing becomes jumbo and the reserve and equity expectations tighten at exactly the moment you are carrying two properties. See the jumbo page.

Frequently asked questions
What is the first thing to check when buying before selling in Colorado?
Whether a property tax benefit is leaving with you. If you are 65 or older with 10 consecutive years of ownership and occupancy, you may hold the senior exemption on 50% of the first $200,000 of actual value, and moving ends it. The portability bridge that existed for tax years 2025 and 2026 was repealed by SB26-116 for years beginning on or after January 1, 2027.
How are Colorado property taxes calculated in 2026?
At a split rate. The 2026 residential assessment rate is 6.8% for non-school local levies and 7.05% for school district levies, and for the local-government portion 10% of the first $700,000 of actual value is subtracted before the rate applies, a maximum subtraction of $70,000. The result is multiplied by your county's mill levy.
Which Colorado counties have higher conforming loan limits?
Twenty of 64 for 2026. Eagle is at the national high-cost ceiling of $1,249,125, Garfield and Pitkin at $1,209,750, Lake and Summit at $1,092,500, Moffat and Routt at $1,089,050, San Miguel at $994,750, Grand at $883,200, Boulder at $879,750, and Adams, Arapahoe, Broomfield, Clear Creek, Denver, Douglas, Elbert, Gilpin, Jefferson and Park at $862,500.
How long does it take to sell a house in Colorado?
It splits sharply by region. For the month ending August 2026, mean days to pending was 45 in Greeley, 48 in Denver, 50 in Colorado Springs and Fort Collins and 52 in Boulder, against a US benchmark of 53. Mountain and Western Slope markets were much slower: 73 in Breckenridge, 81 in Edwards, 86 in Glenwood Springs and 93 in Steamboat Springs.
