By Tom Cunningham, Realtor – Baird & Warner
Purchasing a home is one of the most exciting (and often overwhelming) milestones in life. As a local real estate expert in the Chicago suburbs real estate market, I’ve seen countless buyers fall into the same traps — some of which can cost thousands or even lead to missed opportunities.
Whether you’re a first-time buyer or a seasoned homeowner, here are the top 25 mistakes to avoid when purchasing a home:
1. Not Hiring a Buyer’s Agent
Trying to go it alone in today’s market is risky. A buyer’s agent works solely in your best interest, helps you navigate the negotiation process, and can uncover hidden issues you might overlook. The best part? In some cases, the seller pays all or most of buyers agents compensation
2. Looking at Homes Without Getting Pre-Approved
A mortgage pre-approval isn’t just helpful — it’s essential. It shows sellers you’re serious and gives you a clear picture of your buying power. Without it, you risk wasting time or losing your dream home to someone more prepared.
3. Not Understanding Your Credit Score
Your credit score directly affects your mortgage rate. A few points can cost you thousands over the life of your loan. Before applying, pull your credit report, fix any errors, and work to boost your score if needed.
4. Underestimating the True Cost of Buying
Beyond the down payment, expect closing costs, inspections, property taxes, insurance, moving expenses, and possibly HOA fees. These can add up quickly — I help clients build realistic budgets to avoid sticker shock.
5. Overextending Your Budget
Just because you’re approved for a certain amount doesn’t mean you should spend it. Leave room in your monthly budget for maintenance, upgrades, or emergencies. Financial comfort is better than stretching for granite countertops.
6. Skipping the Home Inspection
In a competitive market, some buyers waive inspections to win bids — but that’s a gamble. A professional inspection can uncover foundation problems, plumbing issues, or hidden safety hazards before you commit.
7. Not Taking Advantage of First-Time Buyer Programs
There are countless grants, down payment assistance programs, and tax incentives available — especially in Illinois. I help first-time buyers explore every option to make homeownership more affordable.
8. Making Major Purchases Before Closing
That new car or furniture set? It can wait. Big purchases affect your debt-to-income ratio and can cause your mortgage approval to fall through, even at the last minute.
9. Not Shopping Around for a Mortgage
Many buyers go with the first lender they talk to. But a slight difference in rates can save you thousands over time. I always recommend getting quotes from at least 2–3 lenders.
10. Falling in Love with the Wrong Features
That open-concept kitchen might wow you, but don’t ignore red flags like an old roof or poor layout. Focus on fundamentals: structure, location, and resale potential.
11. Skipping Neighborhood Research
Location matters — and not just for resale value. Visit the area at different times of day. Research crime rates, schools, commute times, and amenities. A beautiful house in the wrong neighborhood won’t feel like home.
12. Assuming You Need 20% Down
Many buyers wait years to save 20%, not realizing there are strong loan programs with as little as 3–5% down. I can connect you with trusted lenders who’ll walk you through all your options.
13. Forgetting About Taxes and Insurance
Your mortgage payment might seem affordable — until you factor in property taxes and homeowners insurance. These vary by county and home type, and I help clients calculate the full monthly picture.
14. Ignoring HOA Rules and Fees
Homeowners associations (HOAs) can enhance your lifestyle — or restrict it. Before purchasing a home in an HOA, review the rules, fees, and budget to avoid surprises.
15. Waiving Contingencies Without a Strategy
Waiving financing or inspection contingencies might strengthen your offer, but it’s not always wise. If you’re considering it, we’ll create a strategy to minimize your risk.
16. Trying to Time the Market
Real estate is cyclical and unpredictable. Waiting for a “crash” or “perfect moment” can mean missing great opportunities. The best time to purchase a home is when you’re ready, financially and emotionally.
17. Using the Listing Agent as Your Only Agent
The listing agent represents the seller — not you. Dual agency can create conflicts of interest. Protect your interests with a dedicated buyer’s agent (that’s me!).
18. Not Considering Resale Value
Even if you’re buying your “forever home,” life changes. Think about layout, location, and features that will appeal to future buyers in case you need to move.
19. Letting Emotions Take Over
It’s easy to get caught up in bidding wars or picture-perfect decor. I help my clients stay grounded, make data-driven decisions, and avoid overpaying.
20. Not Asking Enough Questions
What’s included in the sale? How old is the furnace? When was the roof replaced? No question is too small. I’ll ask them for you — and help you ask the right ones.
21. Underestimating Renovation Costs
HGTV makes it look easy, but renovation costs can escalate quickly. Always get estimates before buying a fixer-upper — and have a backup budget.
22. Overlooking Title or Survey Issues
Boundary disputes, easements, or unpaid liens can be deal breakers. That’s why I work with experienced title companies to ensure everything is clear before closing.
23. Skipping the Final Walk-Through
A lot can change between inspection and closing. The final walk-through ensures repairs were completed, and that the home is still in the condition you agreed to buy.
24. Not Using a Real Estate Attorney (When Required)
In Illinois, attorneys are a vital part of the transaction. A good real estate attorney reviews your contract, protects your rights, and ensures a smooth closing.
25. Trying to Do It All Alone
Real estate is complex. Surround yourself with a great team — agent (me), lender, attorney, inspector, title rep. I have trusted partners I work with every day, and I’ll be your guide every step of the way.
