Fewer Houses Sold in 77354 This Summer and the Price Barely Moved. Up the Road in Montgomery, Both Went Up.

Greater Houston sold 7,100 single-family homes in August, 11.5 percent fewer than in August 2025, according to the Houston Association of Realtors' monthly report. The median price was $330,000, down $5,000 from a year earlier. A house took 54 days to sell against 52 the year before, and there were 38,947 single-family listings active at month's end, 5.3 months of supply at the August pace. The association's own description of that is a balanced market: more to choose from for buyers, prices roughly flat for sellers.

Zoom in and the picture splits. Redfin's ZIP-level figures, which use a rolling three months ending in August to smooth out small samples, put the median sale in 77354, the ZIP that includes the town center, at $328,308, up 1.8 percent from the same three months last year. Sales fell hard, 360 against 436, a 17.4 percent drop. The median listing took 72 days to go under contract, five fewer than a year ago. Price held, volume did not.

In 77355, which takes in Stagecoach and the west side of town, the median was $299,860, down 2.6 percent, on 180 sales against 187, with a median of 55 days on the market. Pinehurst's 77362 came in at $327,358, down less than 1 percent, on 33 sales against 59 the year before, the steepest drop of the four; a Pinehurst listing went under contract in a median 43 days, the fastest.

Then Montgomery. In 77316 the median sale was $426,810, up 13.8 percent, on 465 sales against 348, a third more. Days on market ran the other way: 91, up from 58. More houses sold there, at higher prices, and they took a month longer to do it. A jump like that in a single year usually says something about what is being sold, not only how much it fetches; new construction around the lake at higher price points moves a median the same way a new subdivision moves a school's enrollment. The figures do not separate new from resale.

A local brokerage's compilation for the Tomball-Magnolia area, reported Monday by Community Impact, agrees on direction: sales down year over year in all five of the ZIP codes it tracks, median prices down in four of five, and days on market up in three, with Stagecoach and Rose Hill the exceptions. Its August-only figures and Redfin's three-month figures will not match to the dollar, and the two sources are stated here side by side rather than blended.

Behind every one of those numbers is a rate. Freddie Mac's weekly survey put the 30-year fixed mortgage at 6.95 percent on Thursday, September 17, up from 6.76 the week before and from 6.26 percent a year ago. The 15-year was 6.26 percent, up from 5.41 a year earlier. The survey tracks conventional loans with 20 percent down and strong credit; most borrowers pay something above it.

Here is what the rate move does to a purchase at the 77354 median, with every assumption stated. Take $328,308, 20 percent down, a loan of $262,646 over 30 years, principal and interest only, no taxes or insurance. At last year's 6.26 percent the payment is about $1,619 a month. At Thursday's 6.95 percent it is about $1,739. The house cost 1.8 percent more than a year ago; the monthly payment on it costs 7.4 percent more, $120 a month, $1,437 a year, because the rate moved further than the price did. The one-week move from 6.76 to 6.95 alone is $33 a month on that loan. Run the same math on the 77316 median and the year-over-year difference is $156 a month.

If a seller in 77354 does nothing different from last year, the data says the house sells after a couple of months on the market and close to asking; Redfin's three-month figure has the typical home in the ZIP closing about 3 percent under list. If a buyer waits, the price side of the equation has been flat for a year and the rate side has not, and neither of those is a forecast of the next twelve months.

Things a household can check, each with a public source: the current week's rate, which Freddie Mac posts every Thursday at noon Eastern; the appraisal district's value on the house against the sale prices on the street, at mcad-tx.org; the days-on-market figure for its own ZIP, which changes month to month; and, for anyone buying in 77316, whether the comparable sales are new builds or resales, because that changes what a 13.8 percent number means.
