1. SummaryResale homes · 52 sales · November 1, 2025 – October 31, 2026
This study looks at the 52 resale homes sold in Blackhawk in the 365 days to October 31, 2026. A full year is used because only 27 resale homes sold in the last 180 days. New construction is left out and shown on its own in section 7. The homes are compared four ways: by price, by living area, by year built and with or without a view. The first three are split into four equal groups (quartiles), each named by its range.
Each comparison has its own section (3–6) with everything about it in one place: the key differences, a table of every measure at a glance, the charts and the numbers.
2. Where the resale homes sold52 resale homes · colored by price range

3. Quartiles by net sale priceResale homes · 52 sales · November 1, 2025 – October 31, 2026
Sales ranked by net sale price and cut into four equal groups. This is the usual way to read a market by price.

6. View and no viewResale homes · 52 sales · November 1, 2025 – October 31, 2026
Sales where the MLS lists a view (greenbelt or park, trees, golf course, hill country, water and similar) against those listing none or only the neighborhood. 3 sales whose MLS view entry is only “See Remarks” are left out.
Bottom line: no measure differs enough between the groups to rule out chance.

7. New constructionBasic statistics · 60 sales · November 1, 2025 – October 31, 2026
Homes sold new by the builder in the same 365 days. They are left out of every other section and shown here as basic figures only: 60 sales, no groups, no tests.
Note: these are only the new-construction sales reported in ABOR MLS. Builders often sell homes without listing them in the MLS, so these figures do not necessarily represent all new-construction sales in Blackhawk.

8. AppendixMeasures, methods and tests
Each measure and method three ways: in plain words, as statistics, and with the data from this study.
8.1 Measures
8.1.1 Net sale price
In simple terms
What the seller actually kept: the closing price, less money the seller gave back to the buyer for closing costs or repairs. It is the truest price for comparing homes.
Statistically
Net = ClosePrice − ACTRIS_BuyersClsgCostPdbySell − ACTRIS_RepairsAmount (a blank counts as $0). Summarized by the arithmetic mean in the slices.
The data
52 resale sales. Average $531,591; median $526,766; standard deviation $176,415; middle half (25th–75th percentile) $417,500–$599,010; lowest $242,750, highest $1,374,500. 30 sales had a seller payment; their median payment was $6,000.
8.1.2 Net price per SF
In simple terms
Net sale price divided by the heated and cooled square feet. It puts homes of different sizes on the same footing: did buyers pay more for each square foot, not just for more square feet?
Statistically
psf = Net ÷ LivingArea, per sale; summarized by the mean of the per-sale ratios.
The data
52 resale sales. Average $184; median $181; standard deviation $29; middle half (25th–75th percentile) $169–$198; lowest $135, highest $297.
8.1.3 Living area
In simple terms
The heated and cooled space, as listed in the MLS. Garages and porches are not counted.
Statistically
RESO LivingArea, in square feet. Sales under 400 SF are treated as entry errors and left out.
The data
52 resale sales. Average 2,894; median 2,815; standard deviation 771; middle half (25th–75th percentile) 2,391–3,403; lowest 1,526, highest 4,689.
8.1.4 Year built
In simple terms
The year the home was finished, as listed in the MLS. It shows whether a group leans to older or newer phases of the community.
Statistically
RESO YearBuilt; summarized by the median, with the 25th–75th percentile (middle half) on the charts.
The data
52 resale sales. Average 2014; median 2016; standard deviation 6; middle half (25th–75th percentile) 2008–2020; lowest 2000, highest 2023.
8.1.5 Days on market
In simple terms
How many days the home was on the market before the buyer's offer was accepted, counting any earlier listing periods (relists). This is the days on market agents and clients quote.
Statistically
CDOM = max(CumulativeDaysOnMarket, DaysOnMarket, PurchaseContractDate − ListingContractDate). The MLS counter can freeze at a price change, so the contract-date gap is a floor. Summarized by the median, because a few homes that sat for months pull an average up.
The data
52 resale sales. Average 87; median 59; standard deviation 75; middle half (25th–75th percentile) 29–136; lowest 2, highest 284. 0 sales went under contract on their listing date (0 days).
8.1.6 Discount from original list
In simple terms
How far below the first asking price the home sold, after seller payments. It measures how much negotiating room sellers gave up. A negative figure means the home sold above its first asking price.
Statistically
Discount % = (OriginalListPrice − Net) ÷ OriginalListPrice × 100, per sale; summarized by the mean.
The data
52 resale sales. Average 7.7%; median 5.2%; standard deviation 7.1%; middle half (25th–75th percentile) 2.8%–9.8%; lowest −0.2%, highest 29.6%. 2 sales closed above their first asking price.
8.1.7 Price cut before sale
In simple terms
The asking price was lowered at least once before the home went under contract.
Statistically
Indicator: ListPrice at close < OriginalListPrice. Reported as the share of sales (%).
The data
29 of 52 resale sales (55.8%).
8.1.8 Seller paid closing costs or repairs
In simple terms
The seller paid some of the buyer's closing costs or repairs.
Statistically
Indicator: ACTRIS_BuyersClsgCostPdbySell + ACTRIS_RepairsAmount > 0. Reported as the share of sales (%).
The data
30 of 52 resale sales (57.7%).
8.1.9 Has a view
In simple terms
The MLS says the home looks over something: a greenbelt or park, trees, golf course, hill country, water and similar.
Statistically
View = the View field holds any entry other than “None”, “Neighborhood” or “See Remarks”. No view = only “None” and/or “Neighborhood”. A record whose only entry is “See Remarks” cannot be classified and is left out of the view slice.
The data
9 sales with a view, 40 without, 3 unclassified. Most common View entries: None 27, Neighborhood 16, Pond 5, See Remarks 3, Park/Greenbelt 3, Pool 2, Trees/Woods 2, Panoramic 2.
8.2 Methods
8.2.1 Data source
In simple terms
Every figure comes from the Austin Board of REALTORS® MLS, read live by ALEX. No figure is estimated or typed in.
Statistically
ABOR MLS via secure APIs, read from ALEX's copy of the MLS (refreshed every 15 minutes; this pull as of 2026-11-01 12:45 UTC), every field. Filter: StandardStatus = Closed, PropertyType = Residential, City = Pflugerville, SubdivisionName contains any of “blackhawk”, “park at blackhawk”, “grove at blackhawk”, “lakeside at blackhawk”, “park at blackhawk vi”, “the park at blackhawk”, “park at blackhawk ii”, “lakeside at blackhawk iii”, “lakeside at blackhawk ii” (case-insensitive). A record is kept when its subdivision name belongs to the Blackhawk family, the same rule comparable sales use (it includes Park at Blackhawk, Grove at Blackhawk, Lakeside at Blackhawk, Park At Blackhawk Vi Sec 1 The, The Park at Blackhawk, Park At Blackhawk Ii Ph 3B Th, Lakeside At Blackhawk Ii Ph 2, proven adjacent and priced alike).
The data
Pulled November 1, 2026: 112 closed Blackhawk records over the prior year, in ZIP 78660. 27 subdivision spellings kept, the most common: Blackhawk (42); Grove at Blackhawk (27); The Park at Blackhawk (4); Park at Blackhawk (4); Park At Blackhawk 4 (3); Park At Blackhawk (3); Park At Blackhawk Vi Sec 1 The (3); Park At Blackhawk Sec 05 (3); Lakeside At Blackhawk Ii Ph 2 (2); Lakeside At Blackhawk Sec 02 (2); Lakeside at Blackhawk (2); Park At Blackhawk 06 Sec 01 The (2); and 15 more (15 records). Names found by the search but not part of Blackhawk, left out: Meadows Blackhawk Ph 01 (5); Meadows Blackhawk Ph 05 (4); Meadows Blackhawk Ph 06 (4); Fairways Of Blackhawk Ph 5A (3); Fairways Blackhawk Ph 04 (3); Park At Blackhawk Iv Ph 6A (3); Park At Blackhawk Vii Sec 1A T (2); Meadows Blackhawk Ph 02 (2); The Groves at Blackhawk (2); Ridge at Blackhawk (2); MEADOWS OF BLACKHAWK PHS 1 (1); Trails at Blackhawk (1); Meadows of Blackhawk (1); Park at Blackhawk and Lakeside (1); Fairways Of Blackhawk Ph 5a (1); Park/Blackhawk Iv Ph 3 (1); Fairways Blackhawk Ph 03-A (1); Ridge/Blackhawk Ph 1 Sec 1 (1); Fairways Blackhawk (1); Park/Blackhawk Vii Sec 3 (1); Park/Blackhawk 6 Sec 5 (1); Fairways Blackhawk Ph 1-A (1); Lakeside/Blackhawk Ii Ph I B (1); Park/Blackhawk 06 Sec U (1); Park/Blackhawk Iii Sec 2 (1); Ridge at Blackhawk Ph 1 Sec 2 (1).
8.2.2 Study window
In simple terms
The most recent 365 days of closed sales: recent enough to describe today's market, long enough to give each group plenty of sales. The usual window is 180 days; it holds only 27 resale sales here (under 80), so the full year is used.
Statistically
CloseDate from November 1, 2025 to October 31, 2026 inclusive.
The data
112 single-family sales in the window: 52 resale, 60 new construction.
8.2.3 Resale and new construction
In simple terms
A resale home was previously owned. New construction is sold by the builder and behaves differently, so it is kept out of every analysis and reported once on its own.
Statistically
New construction = NewConstructionYN true, or PropertyCondition contains “New Construction” or “Under Construction”. Everything else is resale.
The data
52 resale; 60 new construction.
8.2.4 Sales left out
In simple terms
A few records cannot be used as entered and are left out before any analysis.
Statistically
Excluded: PropertySubType other than Single Family Residence; no OriginalListPrice; LivingArea under 400 SF; seller payments above 10% of ClosePrice (treated as entry errors).
The data
None in this window.
8.2.5 Quartiles and groups
In simple terms
Sales lined up from lowest to highest and cut into four groups of about equal size. Each group is named by its range, for example “Under $425K”.
Statistically
Sort by the slicing variable; cut k sits at round(nk/4), k = 1…3. A cut that would split tied values moves to the nearer edge of the tie. A group under 3 sales merges into its smaller neighbor. Range names use the next group's lowest value (“Under”) and the previous group's highest value (“Over”/“After”).
The data
Quartiles by net sale price: Under $425K: $242,750–$395,000 (13 sales); $425K–$524K: $425,000–$523,532 (13 sales); $530K–$598K: $530,000–$598,500 (13 sales); Over $598K: $600,540–$1,374,500 (13 sales) Quartiles by living area: Under 2,391 SF: 1,526–2,390 SF (13 sales); 2,391–2,805 SF: 2,391–2,805 SF (13 sales); 2,825–3,395 SF: 2,825–3,395 SF (13 sales); Over 3,395 SF: 3,427–4,689 SF (13 sales) Quartiles by year built: Before 2008: 2000–2007 (12 sales); 2008–2016: 2008–2016 (15 sales); 2017–2019: 2017–2019 (11 sales); After 2019: 2020–2023 (14 sales) View and no view: View: MLS lists a view (9 sales); No view: None or Neighborhood (40 sales)
8.2.6 Average and median
In simple terms
The average adds the values and divides by how many; one very expensive home can pull it up. The median is the middle value, with half above and half below.
Statistically
Mean x̄ = (1/n) Σ xᵢ; median = 50th percentile. Price, price per SF, living area and discount use the mean; days on market and year built use the median (skewed or whole-year values).
The data
Net sale price: average $531,591, median $526,766. Days on market: average 87, median 59: the average is pulled up by a few long listings.
8.2.7 Kruskal–Wallis test
In simple terms
Checks whether a measure really differs across the four groups of a slice. It uses each sale's rank, not its value, so a few extreme sales cannot drive the answer.
Statistically
H = [12/(n(n+1))] Σ Rⱼ²/nⱼ − 3(n+1), compared with χ² on k − 1 degrees of freedom (Kruskal & Wallis, 1952). Effect size ε² = H/(n − 1): ≥ .01 small, ≥ .06 medium, ≥ .14 large (Tomczak & Tomczak, 2014). A slice is tested only when every group has at least 5 sales; smaller groups are described, not tested.
The data
Run on every measure in sections 3–5; each result is in 8.3.
8.2.8 Mann–Whitney U test
In simple terms
The same check when there are only two groups: view against no view.
Statistically
Two-sided U test (Mann & Whitney, 1947). Effect size = rank-biserial correlation |1 − 2U/(n₁n₂)|: ≥ .10 small, ≥ .30 medium, ≥ .50 large (Kerby, 2014; Cohen, 1988).
The data
Run on every measure in section 6; results in 8.3.
8.2.9 Chi-square test
In simple terms
Checks whether a yes/no share (price cut, seller payment, view) differs between groups more than chance would.
Statistically
Pearson χ² on the 2 × k table of counts, no continuity correction (Pearson, 1900). Effect size Cramér's V = √(χ²/n): ≥ .10 small, ≥ .30 medium, ≥ .50 large (Cramér, 1946).
The data
Run on the three shares in every slice; results in 8.3.
8.2.10 Real difference (significance)
In simple terms
“Real difference” means a gap this large would be very unlikely if the groups were really alike. Because many measures are checked in each slice, the bar is set higher than usual.
Statistically
Significant when p < 0.05 ÷ m, where m is the number of measures tested in that slice (Bonferroni; Dunn, 1961). The slicing variable itself differs by design and is not tested.
The data
Quartiles by net sale price: m = 8, threshold p < 0.0063; Quartiles by living area: m = 8, threshold p < 0.0063; Quartiles by year built: m = 8, threshold p < 0.0063; View and no view: m = 8, threshold p < 0.0063
8.2.11 Size of a difference
In simple terms
A difference can be real but small. The size word (small, medium, large) says how much the groups pull apart.
Statistically
ε² for Kruskal–Wallis, rank-biserial r for Mann–Whitney, Cramér's V for chi-square, with the thresholds above; below the small threshold the size is “negligible”.
The data
3 real differences across the four slices; sizes are listed in 8.3.
8.2.12 Rounding in the text
In simple terms
Headings and sentences round figures so they read easily; the tables at the end of each section give them in full.
Statistically
Prices in headings round to the nearest $1K; price per SF and days on market to the nearest whole number; living area to the nearest 10 SF; shares and percentage gaps to whole percents.
The data
Days on market is always shown in days.
8.3 Test results
Every test behind every gold box. Statistic, degrees of freedom (df), p-value, the threshold it must beat, and the size of the difference.
