The September closing in context

The month supplies one transaction, not a broad pricing trend.

$550,00021536 E Nassau Pl · September 2

A three bedroom detached sale set the monthly average

The home reported 2,816 square feet, 32 days on market and a sale price equal to 95.0% of its original $579,000 list price.

The export’s MLS subdivision field labels this record Saddle Rock Highlands. This report follows the supplied Tallgrass area search set and preserves the original subdivision labels rather than reassigning them.

Pricing and selling conditions

Red and green cues show direction, but the one sale current sample requires extra caution.

Planning around Tallgrass’s current market

The most useful next step is to narrow the report to the home’s property type, size, condition and exact competitive set.

4 of 7
active listings were below their original list price

Current competition has already tested pricing

More than half of the active listings had moved below their original asking positions. The median active market time was 41 days, but the range ran from 8 to 161 days. Launch price and condition should be evaluated together rather than from the community average alone.

For homeowners considering selling

  1. Separate detached, condo and townhome comparisons before choosing a launch price.
  2. Review the seven active competitors and their price histories, not only the one September closing.
  3. Prepare the home for side-by-side buyer comparisons. Four current listings had already adjusted below their original list positions.
  4. Use finished square footage, lot, updates and monthly ownership costs to narrow the comparable set.

For homeowners considering buying

  1. Compare the five detached listings separately from the two attached choices.
  2. Study time on market and price changes. Current active marketing time ranges from 8 to 161 days.
  3. Use the two pending properties as evidence of activity, not proof that every listing is moving at the same pace.
  4. Base an offer on the closest recent sales and the home’s condition instead of the one sale monthly average.

Before choosing a bedroom, finished basement or open recreation area

This dataset does not isolate the value of a single renovation choice.

September 2026 contains only one three bedroom sale, while the prior-year bedroom groups also differed by property type and home size. The data cannot prove that adding a bedroom, finishing a basement or creating a larger recreation area will produce a specific return. Compare matched Tallgrass area sales with similar above-grade size, basement condition, layout and lot before deciding which improvement best fits the home and likely buyer.

Tallgrass market questions

Short answers based on the September report and October 2 inventory snapshot.

How many Tallgrass area homes sold in September 2026?

One home in the supplied search set closed during September 2026, compared with six in September 2025. The current sale was a three bedroom detached home at $550,000.

Does 7.0 months of inventory prove Tallgrass is a buyer’s market?

No. The calculation divides seven active listings by only one September closing. That makes the result highly sensitive to a single transaction. It is best read as a sign of greater current choice relative to this month’s closing pace, not as a permanent market classification.

Why should attached and detached homes be evaluated separately?

The five active detached homes averaged $626,600, while the condo and townhome averaged $367,500. Association costs, size and maintenance responsibilities create different buyer searches, so a blended average can obscure the relevant comparison.

Were Tallgrass area listings reducing their prices?

Four of the seven active listings were below their original list positions. The one September closing sold for 95.0% of its original list price after 32 days on market.

Can this report determine which renovation will add the most value?

No. The workbook does not provide controlled before-and-after comparisons for added bedrooms, finished basements or open recreation areas. A property-specific review of closely matched sales is needed before making that decision.

Data notes: Closed sale comparisons cover September 1–30, 2026 and September 1–30, 2025. Active and pending counts reflect the October 2, 2026 workbook snapshot. New listings use trailing 30-day periods ending October 2 of each year. Months of inventory equals seven active listings divided by one September 2026 closing.

The supplied Tallgrass area export includes MLS subdivision labels such as Tallgrass, Tall Grass, Bristlecone at Tallgrass, Saddle Rock Highlands and related nearby labels. This report follows the supplied geographic search set and preserves those source labels. No duplicate closed or active records were identified using matching addresses, dates and prices.

Sale-to-original-list ratio uses sold price divided by original listed price. A sale is counted below original list when the recorded sold price is lower than the original listed price. “Sold Price” and “Close Price” are treated as equivalent final-sale-price fields. The workbook did not include seller-concession or buyer-financing fields, so those metrics are not calculated.

Mortgage rates are simple averages of the September weekly 30-year fixed-rate readings published in the Freddie Mac PMMS archive. Individual rates vary by borrower and loan terms.
