Kirkland's two studied ZIP codes lead on different measures, so the honest answer names a winner for each kind of resale value rather than crowning one code for everything. At the top of the finished market, 98034 leads: new construction there ranged from about 1,900,000 to 3,400,000 dollars, above the 98033 cluster of 1,800,000 to 2,700,000 dollars (Redfin, 2026). For older homes measured against the new builds that replace them, 98033 leads clearly: its sampled older homes averaged 46.2 percent of new build value, against 35.5 percent in 98034 (Frontier Capitals, 2026). A seller asking which ZIP code has the highest resale values therefore has to say which resale they mean, the price of a finished new home, the retained value of an older home, or the land value a builder will underwrite.
The citywide figure sits between the two stories. In August 2026, homes in Kirkland sold for a median of 1,242,250 dollars after 33 days on market, a level 14.9 percent below the same month a year earlier (Redfin, 2026). That median blends waterfront sales in 98033, family resales across both codes and the early stages of the 98034 builder transition, which is why this post separates the measures instead of leaning on the single number.
Key Findings
- New construction in 98034 reached about 3,400,000 dollars at the top of its recorded range, the highest finished resale ceiling in the study (Redfin, 2026).
- Older homes in 98033 averaged 46.2 percent of new build value across 94 sampled homes, the strongest retained value ratio in either ZIP code (Frontier Capitals, 2026).
- Older homes in 98034 averaged 35.5 percent of new build value across a small 10 home sample, reflecting deeper builder discounts on existing structures (Frontier Capitals, 2026).
- Builders acquired 50.0 percent of sampled 98034 homes and 11.7 percent of sampled 98033 homes, showing where land, rather than the house, drives the price (Frontier Capitals, 2026).
- The combined sample of 104 homes produced an average older home ratio of 45.2 percent, weighted heavily toward 98033 by its larger sample (Frontier Capitals, 2026).
How do the two Kirkland ZIP codes differ as resale markets?
Start with what each market mostly sells. In 98033, the sample of 94 older homes met a market dominated by family buyers, where the house itself, its rooms, its condition and its position near downtown Kirkland or the Lake Washington shoreline, sets the price. Resale value there behaves like a conventional housing market: presentation matters, renovation can pay within limits, and comparable sales of similar homes discipline every asking price. Valuation and recently sold records for the ZIP code are the working evidence for that market (Zillow, 2026).
In 98034, the resale market is splitting in two. One part still sells homes to households in Juanita, Finn Hill and Totem Lake in the ordinary way. The other part increasingly sells sites to builders, and in that part the relevant resale value is not what a family would pay for the ranch but what the residual arithmetic allows a builder to pay for the lot. Five of the 10 sampled homes in that ZIP code went to builders (Frontier Capitals, 2026), a share that, even allowing for the small sample, no purely retail market produces. A 98034 seller who only studies family comparables may therefore miss the larger half of their own market.
Geography explains the split through lot pattern. County records describe compact downtown infill parcels in 98033 beside wider suburban plats in 98034, with sample minimum lots of 2,932 square feet and 7,196 square feet respectively (King County Assessor, 2026). Wider plats support bigger replacement homes, which support the higher new build ceiling, which in turn supports builder bids for the land, even as those same bids discount the existing house to a lower ratio.
Which ZIP code wins on finished and new construction value?
On finished value the verdict is 98034, and the margin is at the top rather than the middle. Its new construction range starts near 1,900,000 dollars and runs to about 3,400,000 dollars depending on the district and lake proximity (Redfin, 2026), while 98033 new construction clusters between 1,800,000 and 2,700,000 dollars depending on size, views and location. The overlap is large, and a prime 98033 waterfront build will outsell an ordinary 98034 build, but the ceiling belongs to the northern code because its lots can carry the largest houses.
That ceiling matters to older home sellers in both codes, because new build prices anchor the land side of every nearby valuation. The worked illustration in the research shows the mechanism: where a new build on a comparable 98033 lot sells for 2,200,000 dollars, the older home nearby changed hands for roughly 1,016,000 dollars at the 46.2 percent ratio (Frontier Capitals, 2026). Where a new two story home sells for 2,400,000 dollars in 98034, the 1968 ranch nearby sold for roughly 850,000 dollars at the 35.5 percent ratio. Same mechanism, different retained share, and the difference between those two outcomes is the ZIP code effect in its clearest form.
Sellers can place their own address on that map with public records. County deed recording shows what nearby properties actually transferred for (King County Recorder's Office, 2026), and the disclosure framework that governs a Washington resale, with the seller statement due within five business days of mutual acceptance, keeps condition arguments anchored to a standard form (Washington State Legislature, 2026). King County context from the Census QuickFacts entry frames both ZIP codes inside one county market (U.S. Census Bureau, 2025), which is a reminder that buyers cross the ZIP boundary freely even when statistics do not.
Which ZIP code wins on the value an older home keeps?
On retained value the verdict reverses, and for most owners of pre-1981 homes this is the measure that decides their outcome. The 98033 older home keeps 46.2 percent of what a new build on its lot would fetch, while the 98034 older home keeps 35.5 percent (Frontier Capitals, 2026). In plain terms, the southern code's ageing houses are still being bought substantially as houses, while the northern code's ageing houses are increasingly being bought as obstacles standing on valuable ground, priced accordingly.
Several forces hold the 98033 ratio up. Family demand concentrates where the shoreline, the waterfront streets and downtown Kirkland compress supply, and the August 2026 city median of 1,242,250 dollars with 33 days on market shows a retail market still transacting at pace (Redfin, 2026). Profile research on buyers and sellers nationally describes the household demand that sustains such markets (National Association of Realtors, 2025), and in Kirkland that demand meets a housing stock that cannot expand inside the built out southern districts.
For a 98034 owner, the lower ratio is not automatically bad news. It signals that the land share of total value is high, and land led value can be tested directly with builders rather than guessed from ratios. The residual illustration in the research, a 2,400,000 dollar new build sale leaving land value near 885,000 dollars after construction costs, margin and site preparation, shows a northern ranch reaching a strong absolute price through the land route even at a modest ratio. Reading how much are older homes worth in Kirkland's 98033 ZIP code beside this post gives southern owners their own version of that calculation, while are homes in north Kirkland worth more than homes in south Kirkland takes up the geographic framing directly.
What should a seller in either ZIP code do with this ranking?
Use the ranking to choose a selling strategy, not to set a price. A 98033 owner with a sound home near the water should usually test the retail market first, price from sold comparables (Zillow, 2026), and treat a builder offer as a floor. A 98034 owner on a wide lot should usually test builder demand first, or at least in parallel, because half the sampled demand for homes like theirs came from that channel and the land arithmetic may beat a retail net after costs.
The cost side of the comparison is common to both codes. Commission runs at the typical 5 to 6 percent documented in the national profile research (National Association of Realtors, 2025), seller closing costs add 1 to 2 percent including the excise tax that Washington collects on the transfer (Washington State Department of Revenue, 2026), and capital gains treatment on any profit follows the federal rules summarised in Publication 523 (Internal Revenue Service, 2025). A ZIP code can win on gross value and lose on net if its typical route carries the heavier ledger, which is why rankings should start conversations rather than end them.
A worked pair of examples may help owners place the ranking in dollars rather than in ratios alone. Consider first a sound older home in 98033 whose comparable new build value on its lot is 2,200,000 dollars: at the sampled 46.2 percent ratio its resale centre is roughly 1,016,000 dollars, and a retail sale there carries the usual ledger of commission, closing costs and carrying time before the owner sees the net. Consider next a dated ranch in 98034 whose lot could support a new home at 2,400,000 dollars: at the 35.5 percent ratio the ranch itself centres near 850,000 dollars, yet the land route can test a residual in a similar neighbourhood of value because builders are buying the finished potential, not the ranch. The two homes can therefore end within reach of each other in net terms while sitting in ZIP codes that the headline ranking separates, which is the practical reason this post refuses to name one code the winner for every purpose. Owners who want to run the same pair of calculations on a real address can borrow the net sheet method in how Kirkland homeowners calculate their net proceeds from a sale and the land test in how Kirkland homeowners determine whether their property is worth more as land, then let written offers arbitrate between the retail and builder readings of their own ZIP code.
Timing interacts with the ranking as well. In a city whose median price fell 14.9 percent in the year to August 2026 (Redfin, 2026), a code whose value sits in land may behave differently from a code whose value sits in houses, since builder demand follows new build prices while retail demand follows household confidence. Sellers who do not need to move immediately can watch which of the two engines, family resales in 98033 or builder acquisitions in 98034, is holding up better in the recorded deeds (King County Recorder's Office, 2026).
How does an off market sale change the ranking for an individual home?
A direct sale does not change which ZIP code leads on any public measure, but it can change which value an individual seller actually captures, through the five standard benefits. Privacy: no public marketing, no showings and no open houses, valuable on waterfront streets in 98033 where a listing becomes a local event. Flexible timing: a closing in 7 to 21 days, or months out with a leaseback, in place of the 60 to 120 plus days a listed older home commonly requires.
No commission keeps the 5 to 6 percent that the listed route charges, worth 45,000 to 54,000 dollars at a 900,000 dollar price in either ZIP code (National Association of Realtors, 2025). No seller closing costs keeps the 1 to 2 percent covering title, excise tax and prorations. No inspections or repairs means the home transfers as it stands, without the 10,000 to 30,000 dollar credits that inspections of this housing stock routinely generate.
Frontier Capitals' role in that route is specific: it sources off-market deals to builders, purchases directly from the seller and places the deal with a vetted builder, and it does not claim to be a builder. For a 98034 owner whose ratio says the land is the prize, that channel speaks directly to the strongest demand in their ZIP code. For a 98033 owner, the same offer functions as a priced alternative that a retail plan must beat on net, not on hope.
One further observation may help owners read their own street through this ranking. Within each ZIP code, the spread between individual homes is wider than the gap between the two codes' averages, so a well positioned 98033 interior home can be worth less than an ordinary 98034 home on a superior lot, and the reverse can hold a few streets away. The ranking therefore works best as a first sorting of strategy, telling a seller which buyer pool to approach first and which comparable sales to gather, rather than as a valuation anyone should bank on. The address level work still has to be done, and it is done with the parcel record, the deed history and a small set of genuinely similar sales, in whichever of the two codes the home happens to sit.
Methodology and limitations
The ZIP comparison rests on the sample compiled for this report: 104 pre-1981 homes, 94 in 98033 and 10 in 98034, with 16 builder acquisitions split 11 and 5 between them (Frontier Capitals, 2026). The imbalance matters. Ratios for 98033 rest on a broad sample, while every 98034 figure, the 50.0 percent builder rate and the 35.5 percent ratio included, is directional because only 10 homes support it. New construction ranges are recorded market ranges, not averages, and they overlap substantially between the codes.
No appraisal, title search or inspection of any individual property was performed for this post, and county level statements rely on the records listed below (King County Assessor, 2026; U.S. Census Bureau, 2025). A single waterfront parcel or an unusually wide northern lot can sit far outside the patterns described, and sellers should settle their own ranking question with comparable sales and written offers for their address.
Conclusion
The highest finished resale values in Kirkland sit in 98034, where new construction reaches about 3,400,000 dollars, while the highest retained value for an older home sits in 98033, where sampled homes kept 46.2 percent of new build value against 35.5 percent in the north. Knowing which of those crowns your own property competes for is the practical use of the ranking.

Frequently Asked Questions
Which Kirkland ZIP code has the highest priced homes overall?
At the top of the finished market, 98034, where new construction ranged to about 3,400,000 dollars (Redfin, 2026). The 98033 range tops out near 2,700,000 dollars, although prime waterfront property there can outprice ordinary northern construction.
Why do older 98033 homes keep more of their value than older 98034 homes?
Because family buyers dominate 98033 and pay for the home itself, while builder buyers in 98034 pay for the lot and discount the structure, producing ratios of 46.2 percent and 35.5 percent respectively (Frontier Capitals, 2026). The difference measures buyer mix more than house quality.
How reliable is the 98034 side of this comparison?
It is directional only, because the sample contains just 10 homes from that ZIP code against 94 from 98033 (Frontier Capitals, 2026). The patterns are consistent with the lot and deed evidence (King County Assessor, 2026), but no seller should price from the 98034 rates alone.
Does the winning ZIP code also net the seller more after costs?
Not automatically. Commission at 5 to 6 percent (National Association of Realtors, 2025) and closing costs at 1 to 2 percent including excise tax (Washington State Department of Revenue, 2026) apply in both codes, and federal gain treatment follows Publication 523 either way (Internal Revenue Service, 2025).
Where can I check what homes near mine actually sold for?
Recorded deed transfers in the county system show completed prices (King County Recorder's Office, 2026), and valuation and recently sold records for both ZIP codes provide the market facing view (Zillow, 2026). Sold prices, not asking prices, are the evidence a ranking should rest on.
