Northwest Hills
This study looks at the 50 resale homes sold in Northwest Hills in the 365 days to October 28, 2026. A full year is used because only 32 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.
Each dot is one resale home, colored by its price range. Use the buttons to show one price range at a time. Click a dot for that sale: address, close date, original and last list price, net sale price, living area, net sale per SF and days on market. Scroll or pinch to zoom.
Sales ranked by net sale price and cut into four equal groups. This is the usual way to read a market by price.
- Homes over $1.61M sell for about $252 per SF (71%) more than homes under $1.08M.
- Homes over $1.61M are about 1,010 SF (40%) larger than homes under $1.08M.
3.1 Key differences
The top group against the bottom group. Only real differences are listed. Section 8 explains each measure.
Higher-priced homes Over $1.61M
- Sell for more per square foot.
- Are much larger.
Lower-priced homes Under $1.08M
- Sell for less per square foot.
- Are much smaller.

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: 0 sales, no groups, no tests.
No new-construction sales were reported in ABOR MLS in this window.
Same definitions as the rest of the study (section 8). New construction = NewConstructionYN true, or PropertyCondition “New Construction” or “Under Construction”.
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
- 50 resale sales. Average $1,385,024; median $1,248,750; standard deviation $501,475; middle half (25th–75th percentile) $1,083,125–$1,605,000; lowest $800,000, highest $3,225,000. 18 sales had a seller payment; their median payment was $10,000.
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
- 50 resale sales. Average $479; median $483; standard deviation $128; middle half (25th–75th percentile) $369–$537; lowest $294, highest $875.
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
- 50 resale sales. Average 2,895; median 2,762; standard deviation 659; middle half (25th–75th percentile) 2,404–3,230; lowest 1,786, highest 4,934.
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
- 50 resale sales. Average 1973; median 1969; standard deviation 12; middle half (25th–75th percentile) 1966–1974; lowest 1959, highest 2024.
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
- 50 resale sales. Average 52; median 29; standard deviation 70; middle half (25th–75th percentile) 5–70; lowest 0, highest 323. 1 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
- 50 resale sales. Average 6.0%; median 3.6%; standard deviation 10.2%; middle half (25th–75th percentile) 0.7%–10.6%; lowest −25.0%, highest 31.1%. 9 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
- 19 of 50 resale sales (38.0%).
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
- 18 of 50 resale sales (36.0%).
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
- 16 sales with a view, 32 without, 2 unclassified. Most common View entries: None 22, Neighborhood 17, Trees/Woods 10, Hill Country 7, See Remarks 5, Panoramic 4, Park/Greenbelt 4, Canyon 3.
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
- Bridge Interactive RESO Web API (OData), ABOR dataset, every field returned. Filter: StandardStatus = Closed, PropertyType = Residential, City = Austin, SubdivisionName contains any of “northwest hills”, “northwest hills mesa oaks”, “highland hills northwest” (case-insensitive). A record is kept when its subdivision name belongs to the Northwest Hills family, the same rule comparable sales use (it includes Northwest Hills Mesa Oaks Ph, Highland Hills Northwest Sec 2, proven adjacent and priced alike).
- The data
- Pulled October 29, 2026: 50 closed Northwest Hills records over the prior year, in ZIP 78731, 78759. 17 subdivision spellings kept, the most common: Northwest Hills Mesa Oaks Ph (15); Northwest Hills (5); Northwest Hills Sec 06 (4); Northwest Hills Sec 13 (4); Northwest Hills Sec 12 (3); Northwest Hills Sec 07 (3); Highland Hills Northwest Sec 3 (2); Northwest Hills Sec 08 (2); Highland Hills Northwest Sec 1 (2); Northwest Hills Sec 01 (2); Highland Hills Northwest Sec 2 (2); Northwest Hills Sec 05 Ph 02 (1); and 5 more (5 records). Names found by the search but not part of Northwest Hills, left out: Northwest Hills Northwest Oaks (6); Northwest Hills Lakeview 03 (4); Townhomes Northwest Hills (2); Northwest Hills Cat Mountain S (2); Northwest Hills Lakeview 02 (1); Northwest Hills Ranch Sec 01 (1); Northwest Hills Ranch Sec 1 (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 32 resale sales here (under 80), so the full year is used.
- Statistically
- CloseDate from October 29, 2025 to October 28, 2026 inclusive.
- The data
- 50 single-family sales in the window: 50 resale, 0 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
- 50 resale; 0 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 $1.08M”.
- 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 $1.08M: $800,000–$1,000,000 (12 sales); $1.08M–$1.25M: $1,082,500–$1,245,000 (13 sales); $1.25M–$1.61M: $1,252,500–$1,610,000 (13 sales); Over $1.61M: $1,650,000–$3,225,000 (12 sales)
Quartiles by living area: Under 2,403 SF: 1,786–2,400 SF (12 sales); 2,403–2,728 SF: 2,403–2,728 SF (13 sales); 2,795–3,263 SF: 2,795–3,263 SF (13 sales); Over 3,263 SF: 3,269–4,934 SF (12 sales)
Quartiles by year built: Before 1966: 1959–1965 (10 sales); 1966–1968: 1966–1968 (13 sales); 1969–1974: 1969–1974 (15 sales); After 1974: 1975–2024 (12 sales)
View and no view: View: MLS lists a view (16 sales); No view: None or Neighborhood (32 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 $1,385,024, median $1,248,750. Days on market: average 52, median 29: 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.
