What does the Old Mill Creek housing market data show?
Every row below is Redfin's final published month for Old Mill Creek, IL. Redfin, through August 2021
| Metric | Value |
|---|---|
| Median sale price | $212,250 |
| Median price per sq ft | $115/sq ft |

| Market condition | Balanced market |
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 Old Mill Creek is frozen at May 2026.
- Typical home value (ZHVI)
- Zillow's estimate of what a mid-market home in Old Mill Creek 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.

What does it cost to buy a home in Old Mill Creek?
Priced off the median sale price of $212,250 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% | $42,450 | $169,800 | $1,133/mo |
| 5% | $10,613 | $201,638 | $1,346/mo |

What income do you need?
Lenders generally want housing costs under 28% of gross income. On the 20%-down payment of $1,133, that implies roughly $48,562 a year before you add taxes and insurance. The median household in Old Mill Creek earns $71,875, about $23,313 more than that threshold — the typical local household clears the payment on a typical local home with 20% down. That puts the price-to-income ratio at 3.0x — close to the historical 3x norm, which is unusual in 2026.

What to do next in Old Mill Creek
What buyers should watch
- The gap between 5% and 20% down here is $212 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 $212,250 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 Old Mill Creek listing goes under contract in 40 days. If yours passes that mark, the market is telling you the price is wrong — not that you need more showings.

- Comparable ZIP-level pricing inside Old Mill Creek varies more than the citywide median suggests — check the ZIP pages below before you set a number.
