Quick answer: If you can wait, aim for March to May 2027. Boulder County single-family sellers got 99.1% to 99.2% of list price in April and May 2026, versus 98.0% in September, per the Colorado Association of REALTORS. On an $800,000 Louisville home, that gap is about $9,600.

Should you sell your Louisville home now or wait for spring 2027?
Wait for spring 2027 if you can carry the home until then without double payments, because Boulder County single-family sellers got 99.2% of list price in May 2026 versus 98.0% in September 2026, about $9,600 more on an $800,000 home. Sell now if you need to move before March, already own your next home, or think your price will slip more than about 1% by spring. Nick Ahrens, a North Denver relocation specialist with eXp Realty, runs this exact math with Louisville sellers before picking a list date.
Here is where Louisville stands today, per Redfin's Louisville housing market page for the three months ending September 2026:
Median sale price: $808,615, down 4.8% from a year earlier. The median price per square foot is $428.
Median days on market: 49, down from 55 a year earlier. Boulder County as a whole sits at 57, per Redfin's Boulder County page.
Homes sold in September: 64, down from 90 in September 2025.
Sale-to-list ratio: 99.2%, and 23.8% of homes sold above list.
Homes with price drops: 38.3%, versus 26.2% across Boulder County.
Louisville is a small market, so one month of sales can swing these numbers. That is why the seasonal pattern below uses Boulder County single-family data, which has hundreds of sales a month.

What does the Boulder County selling calendar show month by month?
Spring paid sellers the most and sold the fastest: April 2026 homes closed at 99.1% of list in a median 50 days, and May at 99.2% in 53 days, versus 96.2% and 84 days in January 2026. Here is the full year for Boulder County single-family homes, per the Colorado Association of REALTORS monthly reports (percent of list price received, then days on market until sale):
October 2025: 97.8% of list, 62 days, 342 new listings.
November 2025: 97.6% of list, 82 days, 164 new listings.
December 2025: 97.5% of list, 77 days, 541 homes for sale.
January 2026: 96.2% of list, 84 days, 549 homes for sale.
February 2026: 97.8% of list, 90 days, 583 homes for sale.
March 2026: 98.4% of list, 66 days, 663 homes for sale.
April 2026: 99.1% of list, 50 days, 499 new listings, 759 homes for sale.
May 2026: 99.2% of list, 53 days, 810 homes for sale.
June 2026: 98.3% of list, 57 days, 864 homes for sale.
September 2026: 98.0% of list, 74 days, 365 new listings, 896 homes for sale.
Two patterns stand out. First, the share of list price climbs from a January low to an April and May peak. Second, competition grows with it: homes for sale rose from 541 in December 2025 to 864 by June 2026.
Monthly median prices also moved, from $790,000 in December 2025 to $912,500 in April 2026 and $829,000 in September 2026. Do not read that swing as your home gaining about 15% in spring. A monthly median moves with the mix of homes that happen to close that month, and the CAR reports note that one month can look extreme on a small sample. The share of list price is the cleaner signal for your own home.
How much more could waiting until spring put in your pocket?
About $9,600 on an $800,000 list price, if your home sells at May's 99.2% of list instead of September's 98.0%. On a $1,000,000 home, the same 1.2-point gap is $12,000. Here is the arithmetic:
$800,000 at 98.0% (September pace): $784,000.
$800,000 at 98.4% (March pace): $787,200.
$800,000 at 99.2% (May pace): $793,600.
$800,000 at 96.2% (January pace): $769,600, or $24,000 less than the May pace.
Now subtract what waiting costs you. If you are still living in the home, your mortgage, HOA dues, utilities and insurance are costs you would pay anyway. If you have already moved or bought your next home, they are double costs. Five months at $4,000 a month is $20,000, which is more than twice the $9,600 spring edge.
Price risk matters too. Louisville's median sale price is down 4.8% from a year ago, per Redfin. A 1% price drop on an $800,000 home is $8,000, which would erase most of the spring edge. I cannot tell you where Louisville prices will be in May 2027, and neither can anyone else.

Why might listing your Louisville home now still be the better move?
Listing now can make sense because you face fewer new competitors: Boulder County added 164 new single-family listings in November 2025 and 499 in April 2026, per the Colorado Association of REALTORS. A buyer touring in November sees fewer fresh options than a buyer touring in April.
Louisville is also moving faster than the county right now. Its median days on market is 49, versus 57 for Boulder County, per Redfin. Hot Louisville homes go pending in about 18 days, and the average home in about 50.
Mortgage rates are the wild card. Freddie Mac's 30-year average was 7.32% on October 22, 2026, down from 7.40% a week earlier and up from 6.19% a year earlier, per the PMMS. At 7.32%, each $1,000 borrowed on a 30-year loan costs about $6.87 a month, so a buyer putting 20% down on an $800,000 home pays about $4,396 a month in principal and interest on a $640,000 loan. If rates fall by spring, more buyers qualify. If they rise, fewer do. I would not bet a list date on a rate forecast.
Is March a smarter target than May for Louisville sellers?
March is the middle ground, not the top: in March 2026, Boulder County homes sold at 98.4% of list in a median 66 days with 663 homes for sale, versus 99.2% and 810 homes for sale in May. March gets you part of the spring price edge, 0.4 points over September, with less competition on the market.
On an $800,000 home, March's 98.4% is $787,200, versus $793,600 at May's pace. The trade-off is speed too: March homes took 66 days, versus 50 to 53 days in April and May. If you list in early March, plan on prep work in January and February: repairs, paint, photos and a price set from the latest Louisville sales.
Which list date fits your situation?
List now if you must close before March or would carry a vacant home at more than about $2,000 a month; otherwise target March to May 2027, when Boulder County sellers got 98.4% to 99.2% of list in 2026.
Choose to list now if:
You need to close before March, or you already own your next home.
Your carrying costs run more than about $2,000 a month and the home is vacant.
Your home shows well today and can be priced right on day one.
Choose early March 2027 if:
You can wait four months without double payments.
You want part of the spring edge with fewer homes for sale around you.
You need time for repairs or updates before photos.
Choose April or May 2027 if:
You have no deadline and no double costs.
You want the highest share of list price the calendar has shown recently.
You are comfortable competing with more listings.
"Spring paid Boulder County sellers about 1.2 points more of their list price than this fall. On an $800,000 Louisville home, that is real money, but it is gone if your price slips 1% or you carry a vacant house for five months." Nick Ahrens, North Denver relocation specialist with eXp Realty.

Frequently Asked Questions
What month do Boulder County homes sell for the highest share of list price?
May. In May 2026, Boulder County single-family homes sold for 99.2% of list price, with April close behind at 99.1%, per the Colorado Association of REALTORS. January 2026 was the low point at 96.2%.
Is it a bad idea to list a Louisville home in November or December?
Not if it is priced right. Boulder County homes sold at 97.6% of list in November 2025 and 97.5% in December 2025, and new listings dropped to 164 in November, so a well-priced home faces less competition. Expect a longer wait: 82 days in November and 77 in December.
How much more could I get by waiting until spring on an $800,000 home?
About $9,600, if your home sells at May's 99.2% of list instead of September's 98.0%. That edge disappears if prices drop about 1% by spring or if you carry a vacant home for several months.
Will mortgage rates be lower by spring 2027?
No one can promise that. Freddie Mac's 30-year average was 7.32% on October 22, 2026, down from 7.40% the week before and up from 6.19% a year earlier. Plan your list date around your own timeline, not a rate forecast.
