There was a family preparing to move to the northwest suburbs of Chicago. After their first offer was outbid by another buyer, they submitted an offer on the next property without an inspection contingency.

The median sale price of homes in Arlington Heights is $499,728 as of June 2026 (Redfin). This is 2.0% lower than a year ago, but the market is classified as very competitive. An average of two offers are made, and transactions are completed in 45 days.

This family secured a contract on the second property by submitting an offer without an inspection contingency. Afterward, they learned through a separate inspection that the roof needed to be replaced soon. Since they had no opportunity to negotiate with the seller, the cost fell entirely on the buyer.

On the other hand, the family had prepared in advance. Thanks to obtaining a mortgage pre-approval, they were able to submit their offer quickly. Within the average transaction period of 45 days, having pre-approval is close to a minimum requirement to survive in the competition.

Illinois, where Arlington Heights is located, has an average effective property tax rate of 1.88%, the second highest in the nation (Tax Foundation, as of 2026, second only to New Jersey). For a $499,728 home, one should expect an annual property tax of around $9,395. Families moving from states with lower tax rates, like California or Georgia, will need to significantly adjust their budget in this regard.

This family chose to include property taxes in their monthly mortgage payment through escrow, which significantly increased their monthly payment compared to just principal and interest. Closing costs should also be prepared at 2-5% of the sale price. For a $499,728 home, this amounts to between $10,000 and $25,000 (Bankrate.com).

Arlington Heights is a suburban area known for its good school district reputation, consistently attracting Korean families. However, school district boundaries can sometimes be divided by a single road, so it is advisable to verify the assigned school for the specific address before finalizing a contract, even when referring to ratings from GreatSchools or Niche.

There was another aspect this family almost overlooked. They had left little in reserves to meet the down payment. Since the roof repair costs were higher than expected, without extra funds, they could have ended up with credit card debt. It is essential to keep at least 3-6 months' worth of living expenses separate from the down payment. Instead of giving up on the inspection out of anxiety after being outbid on the first offer, it would have been safer to enhance their competitiveness by accommodating the seller's closing schedule or increasing the earnest money.

It is also advisable to avoid making large expenditures right before moving. Purchasing a new car or opening a new credit card can disrupt the debt-to-income ratio, potentially altering loan approval conditions at the last minute. In a competitive market like Arlington Heights, a single lender's approval condition can often determine the success of an offer. It is beneficial to compare rates from at least three different lenders (CFPB recommendation).

Long-term residency plans should also be organized in advance. For families with potential job relocations or changes, it is wise to consider how many years they plan to live there and what conditions would be favorable for resale before signing a contract. In areas like Arlington Heights, where school districts are reflected in sale prices, it is worth examining whether the school district premium will be maintained at the time of resale. Rather than giving up on conditions one by one due to haste, establishing a budget and priorities from the start can help maintain stability in the competitive offer process.

Instead of hastily removing conditions from the next offer after being outbid, it is ultimately safer to first reassess pre-approval and budget planning. Since market prices and tax rates can vary by county and time, it is advisable to verify them again before signing a contract. This is not investment or legal advice, and consulting with a professional before finalizing any contract is recommended.
