Is the 78620 ZIP code a buyer's or seller's market?

What are the latest 78620 housing market stats?
Redfin's final published month for this ZIP code. Redfin, through March 2026
| Metric | Value |
|---|---|
| Median sale price | $615,000 |
| Median list price | $729,950 |
| Year-over-year price change | -3.5% |
| Median price per sq ft | $247/sq ft |
| Median days on market | 62 days |
| Active inventory | 291 listings |
| Sale-to-list price ratio | 97.1% |
| Homes sold (that month) | 163 |
| Market condition | Leaning buyer's |
Reading these: months of supply is how long it would take to sell every active listing at the current pace (under 4 months of supply tilts toward sellers, 4 to 5 months is the neutral band, and above 5 months tilts toward buyers — above 7 months is a glut.). Days on market is the median time from listing to accepted offer. Sale-to-list ratio above 100% means bidding over asking is normal here. Price per square foot lets you compare differently sized homes, but it should not be used to value your own.
How have 78620 home prices moved?
Over the three years through Redfin's final published month, the median sale price in 78620 fell 11.4%, from $694,000 to $615,000. The live Zillow value series has fell 1.8% in the last 12 months — the more current read now that the Redfin series has stopped. ZIP-level medians swing harder than citywide ones because far fewer homes sell in a month; read the shape of the line, not any single point.

How does 78620 compare to Dripping Springs, TX?
78620 sits about 3.3 miles from downtown Dripping Springs, but we do not hold ZIP and citywide sale rows for the same period, so putting the two numbers side by side would be comparing different months. The Dripping Springs, TX housing market page has the citywide figures, and the comparison tool puts any two markets against each other.
What does it cost to buy a home in 78620?
Priced off the typical home value of $678,139 at the current 7.03% 30-year fixed rate. Principal and interest only — property taxes, insurance, HOA dues and mortgage insurance are on top and vary too much by property for us to guess.
| Down payment | Cash at close | Loan amount | Monthly P&I |

| 20% | $135,628 | $542,511 | $3,620/mo |
| 5% | $33,907 | $644,232 | $4,299/mo |
Zillow, August 2026 for the price · Freddie Mac via FRED, September 2026 for the rate
Lenders generally want housing costs under 28% of gross income, so the 20%-down payment of $3,620 implies roughly $155,155 a year before taxes and insurance. The median household in this ZIP earns $153,477, about $1,678 short of it — which is why down payment size, not price, usually decides who buys here. Price-to-income runs 4.4x. Typical asking rent here is $2,323/mo, a price-to-rent ratio of 24.3x, which means renting tends to be the cheaper monthly option unless you stay long enough for appreciation to close the gap.
