12 First-Time Homebuyer Mistakes to Avoid in Today’s Market

If you’re planning to take the leap from renter to homeowner, it’s likely you’ve been saving money for a down payment and working to build your credit score. You’ve probably also been looking at home listings and are eager to start shopping.

To help you avoid expensive detours, we asked experienced agents where new buyers often go wrong and how to sidestep the most common first-time homebuyer mistakes.

We’ll kick off the list with what top real estate agents say is the most common new-buyer misstep.

Mistake 1. Starting your home search before knowing what you can truly afford

One of the biggest first-time homebuyer mistakes is shopping for homes before getting a clear handle on your finances.

“A lot of first-time buyers don’t know what they’re qualified for or how much money they can actually spend,” says Bob Anarumo, a Davenport, Florida agent with nearly 25 years of experience. “I run into this quite a bit, and many don’t even know what their credit score is.”

Before browsing listings, you’ll want to get a handle on your budget from several angles: what your lender may approve, what feels comfortable month to month, and what homeownership will cost you beyond the mortgage payment.

That means factoring in your existing debt, property taxes, insurance, utilities, maintenance costs, and any HOA dues, if applicable.

To get a solid number, consult with an experienced lender. For a preliminary look, you can use the home affordability calculator below.

Mistake 2. Waiting too long to get pre-approved

Getting pre-approved after you start house hunting can lead to serious disappointment fast.

“The best time to figure out how much you can afford is before you start looking at houses and falling in love with them,” Anarumo says.

A pre-approval will help you set a realistic price range, clarify your financing options, and make you a stronger buyer when you’re ready to make an offer. It can also uncover issues early, such as a credit fix, documentation gap, or even an opportunity to qualify for a better loan program.

Anarumo says the house hunt is exciting, but it should come after preapproval. And with it, a sense of relief because the homes you tour will be in your price range.

Mistake 3. Believing you need 20% down to buy

A common mistake isn’t buying with too little down; it’s assuming buying is out of reach before exploring your options.

There’s a widespread myth that you must put down 20%. This keeps buyers on the sidelines unnecessarily, especially when low-down-payment loans or assistance programs may be available. Some resources include:

Instead of assuming you need to save for years, talk with lenders about what options fit your situation. Some low-down-payment loans can require as little as 3%-3.5%. You may have more paths to homeownership than you realize.

Mistake 4. Choosing a lender without shopping around

The first mortgage quote you receive shouldn’t automatically be the one you take.

Before deciding, Anarumo recommends talking to multiple lenders, including local lenders and online options. “Talk to the different mortgage brokers, answer their questions, and then ask them about the specifics of the different mortgage programs that are out there.”

Compare interest rate and APR, closing fees, available loan programs, and down payment assistance options. Even small differences in rate, fees, or loan structure can affect your costs.

Mistake 5. Buying at the top of your budget

Just because you can qualify for a certain amount doesn’t mean you should spend it.

Many first-time buyers focus on the mortgage payment alone, leaving them “house poor,” meaning they have too little room for repairs, emergencies, or life in general.

Anarumo advises looking at ownership more broadly. “Look at what it costs to cut the grass, the utilities, and all of the expenses around the property.”

He explains that buying a little below your max budget will leave room for maintenance surprises, higher utility costs, furnishing, and unexpected move-in expenses.

While it may be tempting to buy at the top of your budget, Anarumo says there’s a lot you can do with a lighter-burden home. “I often find that, because of their inexperience, first-time buyers don’t look beyond what they’re seeing — what a home could be.”

Staying flexible can matter more than a few extra square feet or walls that you’ll need to paint later. A home should support your life, not strain it.

Mistake 6. Draining your savings for the down payment

Similar to buying at the top of your budget, using every dollar you have to get into a home can also leave you vulnerable right when you need a cushion most.

Anarumo cautions first-time buyers not to focus so heavily on the down payment that they forget about everything that comes after closing.

His rule of thumb: Don’t buy in a way that leaves you financially exposed on day one — there will be surprises. Keeping reserves can help those surprises feel manageable, not stressful.

Think appliance replacement, emergency plumbing repair, or moving costs.

Mistake 7. Forgetting about closing costs and other upfront expenses

While the need for additional funds after the sale has been addressed above, this mistake involving upfront money warrants its own section — treating your down payment as the finish line.

Closing costs often catch first-time buyers off guard, especially when they’re already stretching to cover a down payment. Depending on the loan and market, these expenses can add up quickly and may include lender fees, appraisal costs, title charges, prepaid taxes, homeowners insurance, and more.

Build these costs into your plan early so you’re not scrambling at the last minute — or worse, coming up short right before closing.

Mistake 8. Skipping or underestimating the home inspection

Some first-time buyers are so eager to capture their desired home that they cut corners on due diligence, especially in competitive markets. That can be an expensive mistake.

Lori Cashi, a top Sarasota, Florida agent with more than 20 years of experience, recalls a buyer who bypassed inspectors she recommended in favor of a cheaper option found online. The inspector missed major issues that could have jeopardized the buyer’s financing.

“He had great reviews online,” Cashi says. “But Yelp isn’t the same as personal referrals and trusted teams.”

The lesson isn’t just “get an inspection.” It’s to take the inspection seriously and work with professionals you trust. Saving a little upfront can cost far more later.

Mistake 9. Letting emotions drive the offer

Buying your first home is emotional. And that’s normal. Letting emotion override your budget or good judgment is where trouble starts.

This mistake can show up as:

• Stretching beyond what you planned to spend
• Waiving protections you may regret waiving
• Rushing because you fear missing out
• Ignoring flaws because you’ve fallen in love with the house

First-time buyers often assume they have to “win” at all costs. In reality, the goal is not just getting a house; it’s getting the right house on terms you can live with.

Cashi says a good agent can help keep emotion from turning into overreach.

Mistake 10. Focusing on the house and overlooking the neighborhood

This is an easy mistake to make. As a first-time homebuyer, you might be captivated by countertops, fixtures, and floor plans while missing the bigger picture.

Anarumo reminds his clients that they’re not just buying a home, they’re buying into a location, which involves commute times, flood risk, insurance costs, nearby development, noise, and resale potential.

His advice to avoid this mistake: ask a lot of questions. “The most successful buyers are the ones who don’t assume they know it all.”

Ask about the neighborhood. Drive it at different times. Visit more than once, at different times of day and night. A beautiful house in the wrong location can become a costly regret.

Mistake 11. Making big financial moves before closing

One of the most avoidable first-time buyer mistakes happens after you’re under contract. You may feel like the hard part is over, but lenders often recheck finances just before closing.

That means now is not the time to finance a car, open new credit cards, or change jobs without discussing it with your lender. Even well-intentioned moves can create problems for underwriting.

When in doubt, keep your finances steady until you have the keys in hand.

Mistake 12. Trying to do it all without a trusted team

This may be the hardest first-time homebuyer lesson of all: You don’t need to know everything. A good agent, a responsive lender, and reliable inspectors can help you avoid mistakes before they become expensive.

Cashi’s story about the inspector is a reminder that cutting corners on expertise can backfire. Trusted referrals can matter.

Anarumo says this is another area where buyers do well to ask questions and lean on professionals. “I had this buyer who didn’t have a clue, but asked a whole lot of questions. I think that’s one of the reasons why everything went so well.”
