The final water bill Carpentersville settles before the keys change hands
Selling in Carpentersville starts with a form most sellers meet the week of closing. You or your closing attorney ask the Village for a final water bill. It gets emailed two business days before closing, it has to be paid at or before closing, and the account won't move to the buyer until it is. Water runs $6.00 and sewer $5.74 per 1,000 gallons, billed every two months, and a five-year rate increase program started in November 2025.
What you won't find is a village transfer stamp. A title company's stamp list shows only the final water bill and meter reading for Carpentersville. Ask your title company to confirm anyway. The state and Kane County stamps still apply, and the Kane County page lays out both rates.
A housing stock split by decade
The median home here was built in 1976. More than half the village's roughly 11,900 homes predate 1980, and about 70 percent are single-family detached. About 71.5 percent of occupied homes are owner-occupied.
If your house was built before 1978, you owe the buyer the federal lead pamphlet and disclosure, plus a 10-day window for a lead inspection. That applies whether you list or sell to a cash buyer, so have the paperwork ready either way.
Old Town's lead water lines are gone
There's good news on pipes. The Village started with Old Town, where it knew of lead water service lines, and says it replaced every known one by December 2024. That's worth pointing out to a buyer who asks about water lines in an older house, and the Village posts its service line inventory online if you want to check your own address first.
Dundee Township bills, District 300 and the redemption clock
Carpentersville sits mostly in Dundee Township, with a slice in Rutland Township. For tax year 2024, most village tax codes carried a combined rate of about 7.57 percent, and District 300 schools take the biggest share. Kane County reassesses every four years at one-third of market value, and the homestead exemption takes up to $8,000 off. Late payments add 1.5 percent a month, and the Kane County page covers the October tax sale.
If a mortgage falls behind, redemption runs until the later of 7 months from service or 3 months after judgment, and it ends before the sale. The Kane County page walks through the court steps, the sheriff sale and the rest.
The honest math on Carpentersville's $310,000 median
Redfin put the village's median sale price at $310,000 in May 2026, across 27 sales, up about 7.6 percent from $288,000 a year earlier, with a median 39 days on market. Commission at about 4.9 percent, Clever's Illinois average as updated in September 2026, is roughly $15,200. Closing costs near 1.2 percent add about $3,700. The state stamp is $310 and the county stamp $155. For taxes, take a third of the price, subtract the $8,000 homestead exemption and apply about 7.57 percent. That's a rough $7,200 a year, about $600 a month, plus water. Two months of carrying puts the listing route near $20,500 before repairs.
A cash sale still pays the final water bill and both stamps. It can drop commission, showings and repair requests. If the property is a fit, a cash buyer may make an offer, and you pick the closing date. A house in good shape may net more on the market, so compare both numbers.
