The biggest mistakes happen before you make an offer

First-time homebuyers most often stumble by moving too fast, skipping steps that seem boring, or not understanding what lenders actually require. The mistakes that cost the most money happen early: getting pre-approved for the wrong loan amount, not checking your credit report before explore, making a large purchase on credit right before closing, or not saving enough for a down payment and closing costs. These are not surprises that happen to you — they are decisions you make, usually without realizing the cost.

The good news is that every one of these mistakes is preventable if you know what to watch for. This guide walks through the real stumbling blocks and what to do instead.

Key Takeaways

  • Get pre-approved by a lender before house hunting, and understand the difference between pre-approval and pre-qualification — one is a real commitment, the other is not.
  • Check your credit report at least three months before you plan to buy, because errors take time to fix and your credit score directly affects your interest rate.
  • Do not make large purchases, open new credit cards, or change jobs in the months before closing, because lenders re-check your finances right before funding the loan.
  • Save for both your down payment and closing costs separately — closing costs typically run 2 to 5 percent of the loan amount and are often a surprise to first-time buyers.
  • Get a home inspection and a title search before you commit to the purchase, because these uncover problems that can cost thousands to fix after you own the house.

Not getting pre-approved before house hunting

Many first-time buyers start looking at houses before they know what they can actually afford. They fall in love with a property, make an offer, and then discover the lender will not give them the money. By that point they have paid for an inspection, an appraisal, and process fees — and they have lost the house.

Pre-approval is a lender's written statement that they will loan you a specific amount of money at a specific interest rate, based on your income, debts, credit score, and assets. It is not a may provide — the lender will still verify everything before closing — but it is a real commitment. Pre-qualification, by contrast, is just a rough estimate based on what you tell them over the phone. It means almost nothing.

Get pre-approved before you start looking. This tells you the actual price range you can afford, it shows sellers you are serious, and it protects you from falling in love with a house you cannot buy. The pre-approval letter is good for 60 to 90 days, so time it so it does not expire before you make an offer.

Ignoring your credit report and credit score

Your credit score determines the interest rate you pay on your mortgage. A score that is 20 points lower can cost you tens of thousands of dollars over the life of the loan. Many first-time buyers do not check their credit report until they explore for a mortgage — and by then it is too late to fix errors.

Pull your credit report at least three months before you plan to buy. You can get it free once per year from each of the three credit bureaus (Equifax, Experian, and TransUnion) at annualcreditreport.com. Look for accounts you do not recognize, late payments that should not be there, and incorrect balances. If you find an error, dispute it with the bureau in writing — this takes time, so start early.

While you are checking your report, also look at what is hurting your score. High credit card balances, recent hard inquiries, and accounts in collections all lower your score. You cannot fix everything in three months, but you can pay down balances and avoid new inquiries before you explore for the mortgage.

Making large purchases or opening new credit before closing

Lenders do not just check your finances once, at pre-approval. They check again right before they fund the loan — sometimes just days before closing. If you have bought a car, opened a new credit card, or taken out a personal loan in the meantime, the lender may back out or demand a larger down payment.

This happens because your debt-to-income ratio — the percentage of your monthly income that goes to debt payments — affects how much you can borrow. A new car payment can push you over the limit. A new credit card, even if you do not use it, lowers your available credit and can lower your score.

From the day you get pre-approved until the day you close, do not make large purchases, do not open new credit accounts, and do not change jobs or take a leave of absence. If something changes, tell your lender when ready. It is better to have the conversation early than to discover at closing that the deal is off.

Underestimating closing costs and not saving enough

Closing costs are the fees you pay to the lender, the title company, the appraiser, and the inspector. They typically run 2 to 5 percent of the loan amount. On a $300,000 mortgage, that is $6,000 to $15,000. Many first-time buyers budget for a down payment but forget about closing costs entirely, then scramble to find the money at the last minute.

Ask your lender for a Closing Disclosure form as soon as you have a mortgage offer. This is the official document that lists every fee you will pay. It is not final — some numbers may change — but it gives you a real number to plan for. Do not assume the seller will pay all your closing costs; in some markets they do, in others they do not, and it depends on your offer.

Save for down payment and closing costs as separate buckets. Your down payment is typically 3 to 20 percent of the purchase price. Closing costs come on top of that. If you do not have both amounts saved before you make an offer, you may not be ready to buy.

Skipping the home inspection or title search

A home inspection costs $300 to $500 and takes a few hours. A title search costs $100 to $200. These feel like optional expenses when you are already spending money on the appraisal and the process. They are not. They are the only things standing between you and buying a house with a foundation problem, a roof that needs replacement, or a lien against the property.

The inspection is your chance to learn what is actually wrong with the house. The inspector walks through every system — plumbing, electrical, HVAC, roof, foundation — and documents what needs repair. You can use this report to negotiate with the seller, to budget for repairs after you buy, or to walk away if the problems are too expensive.

The title search confirms that the seller actually owns the property and that there are no liens, judgments, or other claims against it. If someone else has a legal claim to the house, you could end up in court or lose the property. The title company also issues title insurance, which protects you if a claim shows up after you close.

Not understanding the difference between loan types

First-time buyers often accept whatever loan the lender offers without understanding the terms. The main types are conventional loans (which require a credit score of usually 620 or higher and a down payment of 3 to 20 percent), FHA loans (which allow lower credit scores and down payments as low as 3.5 percent but require mortgage insurance), VA loans (for military members and veterans), and USDA loans (for rural properties). Each has different requirements, costs, and rules about what repairs the house must have before closing.

Ask your lender to explain the loan type they are offering and why. Ask what the interest rate is, whether it is fixed or adjustable, what the monthly payment will be, and what fees are included. Ask about mortgage insurance — whether you will need it, how much it costs, and when you can remove it. Do not sign anything until you understand every number.

Choosing the wrong real estate agent or lender

Your real estate agent and your lender have enormous influence over whether the purchase goes smoothly. A bad agent may push you to offer more than the house is worth or rush you into a deal without inspecting the property. A bad lender may quote you a low rate and then add fees at closing, or may not communicate clearly about what you need to do.

Interview at least two agents and two lenders before you commit. Ask for references from other first-time buyers. Ask how they handle problems — what happens if the appraisal comes in low, or if the inspection finds major issues. Ask what they will do to keep the deal on track. The agent and lender you choose will be your guides through the most expensive purchase of your life. Choose people you trust.

Frequently Asked Questions

What credit score do I need to buy a house?

Conventional loans typically require a credit score of 620 or higher, though scores above 740 get better interest rates. FHA loans allow scores as low as 580 with a 3.5 percent down payment, or 500 to 579 with 10 percent down. Your exact score determines your interest rate, so even small improvements matter.

How much should I save for a down payment?

Down payments range from 3 percent (conventional or FHA) to 20 percent or more. A larger down payment lowers your monthly payment and may eliminate mortgage insurance. However, you also need to save for closing costs, so do not drain your savings to hit 20 percent if it leaves you with no emergency fund.

Can I use a gift for my down payment?

Yes, most lenders allow down payment gifts from family members. However, you will need a signed letter from the gift-giver stating that the money is a gift and does not need to be repaid. The lender will verify the source of the money, so be prepared to show bank statements.

What happens if the appraisal comes in lower than the purchase price?

If the house appraises for less than you offered, the lender will only loan you the appraised value. You can renegotiate with the seller, pay the difference out of pocket, or walk away. This is why getting pre-approved for the right amount and not overbidding matters.

Do I need to hire a real estate attorney?

Requirements vary by state. Some states require an attorney to close the sale; others do not. Ask your lender and agent whether an attorney is required in your state. If it is optional, consider hiring one anyway — the cost is usually $500 to $1,500 and can protect you from signing contracts with hidden problems.
