How to read these numbers
- Median sale price
- Half the homes that closed sold for more than this, half for less. It moves with what kind of home sold that month, so a quiet month with two big sales can swing it. Redfin's figure for Lannon is frozen at May 2026.
- Typical home value (ZHVI)
- Zillow's estimate of what a mid-market home in Lannon is worth right now, whether or not it sold. It is smoother than the median sale price and it still refreshes monthly, which is why this page leads with it.
- Months of supply
- How long it would take to sell every active listing at the current pace. Under 3 favors sellers, over 6 favors buyers, and 3 to 6 is the balanced band.
- Days on market
- Median time from listing to accepted offer. Short means you should have financing ready before you tour; long means there is room to negotiate on price and repairs.
- Sale-to-list ratio
- Sale price divided by the last asking price. Above 100% means bidding above asking is normal here; below 100% means the typical buyer got a discount.
- Price per square foot
- The size-adjusted price. Use it to compare a 1,400 sq ft house to a 2,600 sq ft house, not to value your own home — lot, condition and age move it a lot.
- Listings with a price cut
- Share of active listings that dropped their asking price in the month. A high share is the earliest visible sign that sellers are ahead of what buyers will pay.
- Typical asking rent (ZORI)
- Zillow's repeat-rent index for asking rents on new leases. Paired with the home value it gives the price-to-rent ratio in the rent-vs-buy section below.
How have Lannon home prices moved?
Over the last three years the median sale price in Lannon, WI rose 17.4%, from $502,450 to $589,900. The live Zillow value series has rose 6.8% in the last 12 months, which is the more current read now that Redfin's series has stopped. 6.3% of Lannon listings cut their asking price in the final Redfin month — a modest share, which is what a market looks like when sellers are pricing close to where homes actually clear. For prices to fall meaningfully from here, supply would have to keep building past 2.7 months while the sale-to-list ratio slips below its current 100.3%. Watch those two together — they move before the median does.

What does it cost to buy a home in Lannon?
Priced off the typical home value of $519,926 at the current 7.03% 30-year fixed rate. These are principal and interest only — property taxes, homeowner's insurance, HOA dues and mortgage insurance are on top, and they vary enough by property that we will not guess them for you.
| Down payment | Cash at close | Loan amount | Monthly P&I |
|---|---|---|---|
| 20% | $103,985 | $415,941 | $2,776/mo |
| 5% | $25,996 | $493,929 | $3,296/mo |

What income do you need?
Lenders generally want housing costs under 28% of gross income. On the 20%-down payment of $2,776, that implies roughly $118,956 a year before you add taxes and insurance. The median household in Lannon earns $79,191, about $39,765 short of that threshold — the typical local household needs a larger down payment, a co-borrower, or a home below the typical home value to fit the 28% rule. That puts the price-to-income ratio at 6.6x — well above the 3x that was historically considered affordable, which is why down payment size drives who can buy here.

Is it cheaper to rent or buy in Lannon?

Is inventory rising or falling in Lannon?
Active listings in Lannon, WI went from 3 in April 2025 to 16 in May 2026, a +433.3% change. Rising inventory is the single most useful leading indicator for buyers: more choice, longer marketing times, and more sellers willing to negotiate before price cuts show up in the median.

What to do next in Lannon
What buyers should watch
- Months of supply, currently 2.7. It turns before price does — when it climbs past 6, sellers start taking offers they would have rejected a quarter earlier.
- The share of listings cutting price, currently 6.3%. A listing that has already cut once is the one most likely to accept below asking.
- The gap between 5% and 20% down here is $520 a month in principal and interest alone, before mortgage insurance. That gap, not the price, is usually what decides your timeline.
- Rate moves. At 7.03%, every full point of rate change moves the payment on a $519,926 home more than a 5% price change does.
- Your credit tier before you shop, not after — it sets the rate you are quoted. Run your numbers first.
What sellers should know
- The median Lannon listing goes under contract in 89 days. If yours passes that mark, the market is telling you the price is wrong — not that you need more showings.
- Homes here close at 100.3% of asking. Price at the number you want and let competition do the rest.
- Your equity moved +6.8% in the last 12 months on the Zillow value series. That, not the price you paid, is what sets your net proceeds.
- Comparable ZIP-level pricing inside Lannon varies more than the citywide median suggests — check the ZIP pages below before you set a number.
