Buying a home is exciting, but it’s also one of the largest financial decisions most people will ever make. Even experienced buyers can make mistakes that cost them money, create unnecessary stress, or potentially put their purchase at risk.

After helping buyers for more than 24 years and showing thousands of homes, I’ve seen many of the same mistakes repeated. Fortunately, most can be avoided by knowing what to watch for before and during the homebuying process.

1. Shopping Before Getting Pre-Approved

Looking at homes before knowing what you can comfortably afford can lead to disappointment and wasted time.

How to avoid it: Get fully pre-approved before seriously shopping so you understand your price range, estimated payment, and financing options.

2. Buying at the Maximum You’re Approved For

Just because you qualify for a certain amount doesn’t mean you should spend it. Property taxes, insurance, HOA dues, maintenance, utilities, and everyday expenses still matter.

How to avoid it: Choose a monthly housing payment that fits comfortably within your overall budget.

3. Making Large Purchases After Pre-Approval

Buying a car, financing furniture, opening a new credit card, or taking on other debt can affect your loan qualification even after you’ve been pre-approved.

How to avoid it: Before taking on new debt, talk with your lender.

4. Moving or Depositing Large Amounts of Money

Large deposits or transfers between accounts during the transaction may need to be documented and could complicate underwriting.

How to avoid it: Check with your lender before moving significant amounts of money and keep records of any transfers or deposits.

5. Changing Jobs During the Transaction

Changing employers, becoming self-employed, or altering your compensation method may impact your loan approval.

How to avoid it: Talk with your lender before making employment or income changes until after closing.

6. Ignoring Your Agent’s Advice

Your real estate agent shouldn’t make decisions for you, but an experienced agent may recognize risks or opportunities that aren’t immediately obvious.

How to avoid it: Ask your agent to explain the reasoning behind their recommendation. Then make your decision with the benefit of that experience.

7. Choosing an Agent Just Because They Showed You the House

The person who opens the door isn’t necessarily the person you want representing you through negotiations, inspections, disclosures, and closing.

How to avoid it: Choose an agent based on experience, communication, market knowledge, negotiation skills, and trust.

8. Focusing Too Much on Cosmetic Problems

Paint colors, flooring, furniture, and outdated fixtures can distract buyers from an otherwise good home. Those things can usually be changed. Location, lot, neighborhood, and sometimes the floor plan cannot.

How to avoid it: Focus first on the things that are difficult or expensive to change.

9. Waiting for the Perfect Home

Very few homes check every box. Waiting for perfection can cause buyers to pass on properties that meet nearly all of their important needs.

How to avoid it: Know your must-haves, nice-to-haves, and deal breakers before you start looking.

10. Trying Too Hard to Get a Bargain

Everyone wants a good deal, but making an unnecessarily low offer can cost you a home you really want, especially when there is competition.

How to avoid it: Consider comparable sales, property condition, competition, and current market conditions before deciding what you’re willing to offer. Make your best offer upfront. Don’t expect the seller to counter.

11. Not Investigating the Property Thoroughly

A remodeled kitchen shouldn’t distract you from potentially expensive issues involving the roof, foundation, drainage, plumbing, electrical system, sewer, or other major components.

How to avoid it: Carefully review disclosures, obtain appropriate inspections, and investigate concerns before moving forward.

12. Looking Only at the HOA Fee

When buying a condo or townhome, the monthly HOA fee tells only part of the story. A low fee isn’t necessarily good if the association doesn’t have adequate reserves.

How to avoid it: Review available HOA financials, reserves, budgets, insurance, meeting minutes, rules, restrictions, litigation, and other important documents.

13. Overlooking Special Assessments

Major repairs to roofs, balconies, siding, elevators, plumbing, and other common areas can result in additional costs to homeowners.

How to avoid it: Look for existing or proposed special assessments and indications that major projects may be coming.

14. Waiving Contingencies Without Understanding the Risk

Removing or shortening inspection, appraisal, or loan contingencies can make an offer more competitive, but it may also increase your financial risk.

How to avoid it: Understand exactly what protection you’re giving up before removing a contingency.

15. Assuming You’re Done Once the Loan Is Approved

One of the biggest misconceptions is that once you’re approved, you can return to normal financial activity. Your lender may review your finances again before closing.

How to avoid it: Until the transaction closes, avoid new debt, large purchases, unexplained money transfers, or significant employment changes without speaking with your lender first.

The Bottom Line

Buying a home isn’t simply about finding a property you like. It’s about recognizing value, understanding potential problems, making informed decisions, and avoiding mistakes that could become expensive later.

After 24 years in real estate and thousands of home showings, one thing I’ve learned is that the best buyers aren’t necessarily the ones who know everything—they’re the ones who ask the right questions and surround themselves with experienced professionals.

Buyer Question of the Month

What’s more important when buying a home: the house or the location?

Both matter, but remember that many things about a house can be changed. You can remodel a kitchen, replace flooring, change paint colors, or update bathrooms. You can’t move the property to another neighborhood.

When deciding between homes, consider not only what the house looks like today, but also the location, neighborhood, lot, commute, surroundings, and how well the property fits your long-term plans.
