You found the house. It’s perfect. The kitchen is exactly what you pictured, the backyard is big enough for the dog, and you can already see yourself unlocking that front door for the first time.
Then reality hits. Your credit score isn’t where it needs to be. Your dream lender says you’re not approved for what you thought. Or worse, you lose the house to another buyer who was simply more prepared than you.
This happens to first time home buyers every single day, and it’s almost always avoidable.
Quick Answer: The biggest mistakes first time home buyers make happen before they ever tour a home. These include not checking their credit score, skipping mortgage pre-approval, underestimating closing costs, ignoring down payment assistance programs, and shopping for homes outside their real budget. Fixing these five things first can save you thousands of dollars and weeks of heartbreak.
The truth is, buying a house feels overwhelming for almost everyone. So let’s slow down and fix the mistakes before they cost you the home you actually want.
Mistake #1: Not Checking Your Credit Score Early
Here’s what most first time home buyers don’t realize: your credit score isn’t just a number lenders glance at. It directly decides your mortgage rate, your loan options, and how much house you can actually afford.
A higher score often means a lower interest rate. Over a 30-year mortgage, even a half-percent difference can mean tens of thousands of dollars in extra interest.
Why This Mistake Happens
Most people assume their credit is “probably fine” until a lender tells them otherwise. By then, it’s often too late to fix anything quickly.
What a Healthy Score Looks Like
Most conventional loans want a credit score of 620 or higher, according to the Consumer Financial Protection Bureau. FHA loans allow scores as low as 500 with a larger down payment, or 580 with just 3.5% down.
What to do instead: Pull your credit report at least three to six months before house hunting. This gives you time to fix errors, pay down balances, and avoid new debt that could hurt your approval.
Mistake #2: Skipping Mortgage Pre-Approval
This is where many buyers make a costly mistake. They start browsing Zillow, fall in love with a home, and only then talk to a lender.
Pre-approval isn’t the same as pre-qualification. Pre-qualification is a rough guess. Pre-approval means a lender has actually reviewed your income, debt, and credit, and is ready to lend you a specific amount.
Real estate agents and sellers take pre-approved buyers seriously. In competitive markets, an offer without pre-approval often gets ignored entirely.
Real example: Maria, a 29-year-old teacher in Ohio, found her ideal starter home after only two weekends of searching. She lost it to another buyer because her pre-approval letter came in two days too late. She got pre-approved before touring homes the second time around, and closed on a house within five weeks.
Mistake #3: Underestimating Closing Costs
Buyers often save carefully for a down payment, then forget something equally important: closing costs.
Closing costs typically run 2% to 5% of the home’s purchase price, according to the Consumer Financial Protection Bureau. On a $300,000 home, that’s $6,000 to $15,000 due at closing, on top of your down payment.
What Closing Costs Usually Include
- Loan origination fees
- Home appraisal and inspection fees
- Title insurance
- Property taxes and homeowners insurance (prepaid)
- Attorney or escrow fees
Why this matters: Buyers who forget this step sometimes get to the closing table short on funds, which can delay or even cancel the sale.
Mistake #4: Ignoring Down Payment Assistance Programs
Many first time buyers assume they need 20% down. In reality, that number is largely outdated.
FHA loans allow down payments as low as 3.5%. Some conventional loans allow as little as 3% down. In fact, thousands of state and local down payment assistance programs exist specifically to help first time buyers, according to HUD.
Common Loan and Assistance Options
| Program Type | Typical Down Payment | Best For |
| FHA Loan | 3.5% | Buyers with lower credit scores |
| Conventional Loan | 3–5% | Buyers with strong credit |
| VA Loan | 0% | Eligible veterans and service members |
| USDA Loan | 0% | Rural and suburban buyers |
| State/Local DPA Programs | Varies | Buyers needing upfront cash help |
Skipping research here often means leaving thousands of dollars in assistance unused, simply because no one asked.
Mistake #5: House Hunting Outside Your Real Budget
It’s easy to fall for a home priced higher than what you were approved for. Agents sometimes show homes slightly above budget to “see what you love.” However, this often backfires emotionally and financially.
Once you fall in love with a $380,000 home, a $320,000 budget suddenly feels disappointing, even though it’s the smarter, safer choice.
Why this matters: Comparing homes above your budget creates emotional attachment to something you can’t comfortably afford, which leads to stress, rushed decisions, or overextending your finances.
The Smarter Way: A Simple Step-by-Step Plan
Instead of jumping straight into home tours, follow this order:
- Check your credit score and dispute any errors immediately.
- Pay down high-interest debt to improve your approval odds.
- Research down payment assistance programs in your state.
- Get pre-approved, not just pre-qualified, by a licensed lender.
- Calculate your true budget, including closing costs and moving expenses.
- Set a firm price ceiling before touring a single home.
- Start house hunting with confidence, not guesswork.
This order matters because each step builds on the one before it. Skipping ahead is exactly how buyers end up disappointed, rejected, or financially stretched.
Common Mistakes First Time Buyers Make (Recap)
- Assuming their credit is “good enough” without checking
- Confusing pre-qualification with pre-approval
- Forgetting closing costs entirely
- Believing they need 20% down to buy a home
- Falling in love with homes above their real budget
Every one of these mistakes feels small in the moment. Together, though, they’re the reason so many people stay stuck renting far longer than they planned.

FAQ Section
How much credit score do I need to buy my first home? Most conventional loans require a credit score of at least 620. FHA loans allow scores as low as 580 with 3.5% down, or 500 with 10% down.
What’s the difference between pre-qualification and pre-approval? Pre-qualification is a quick estimate based on self-reported information. Pre-approval involves a lender verifying your income, debt, and credit, resulting in a specific loan amount you’re approved to borrow.
How much money do I actually need to buy a house? Beyond your down payment, budget 2% to 5% of the home’s price for closing costs, according to the Consumer Financial Protection Bureau. This covers fees like appraisals, title insurance, and loan origination.
Do I really need 20% down to buy a home? No. Many first time buyers qualify with 3% to 3.5% down through FHA or conventional loans. Programs through HUD also offer down payment assistance in many states.
What credit mistakes should I avoid before applying for a mortgage? Avoid opening new credit cards, taking out new loans, or making large purchases before closing. These actions can lower your score or increase your debt-to-income ratio right when lenders are reviewing it.
How long before buying a house should I check my credit? Check your credit at least three to six months before house hunting. This gives you enough time to dispute errors and improve your score if needed.
What is a good first step if I don’t know where to start? Start by pulling your free credit report and calculating your realistic monthly budget. From there, research loan programs and get pre-approved before touring any homes.
