Mortgage Mistakes: A First-Time Buyer Checklist
Buying your first home is exciting, but applying for a mortgage can feel like a lot when you don’t know what lenders will review.
The most common first-time buyer mistakes involve changing credit, moving money without records, underestimating closing costs, and shopping before completing a solid pre-approval.
In this guide, I’ll explain what to avoid, why these mistakes matter, and how to prepare for a smoother mortgage process.
Key Takeaways
- Credit: Avoid opening accounts, increasing balances, or missing payments before closing.
- Cash: Keep clear records for deposits, transfers, gift funds, and money needed at closing.
- Pre-Approval: Review income, assets, credit, and estimated payments before making an offer.
- Loan Choice: Compare the full loan structure, not only the interest rate.
- Communication: Tell your loan consultant about financial changes before taking action.

Quick Answers for First-Time Home Buyers
- Should I get pre-approved before looking at homes? Yes. A complete pre-approval helps you understand a reasonable price range, estimated payment, and cash needed before you make an offer.
- Is the lowest advertised rate always the right choice? Not necessarily. Rates can include points, lender fees, or loan terms that change the total cost.
- Can I open a new credit card before closing? It is better to speak with your loan consultant first. A new account or inquiry may affect your credit score and monthly debt calculation.
- Can I move money between accounts during the loan process? You can, but large transfers may need to be documented. Keeping the money in one account can make the review easier.
Mistake 1: Shopping Before Getting Fully Pre-Approved
Looking at homes before reviewing the mortgage numbers can create problems. An online calculator may give you a general estimate, but it does not review your credit, income, monthly debts, property taxes, homeowners insurance, or available cash.
A mortgage pre-approval is a lender review of your credit, income, assets, debts, and proposed loan terms. It is stronger when the requested documents have been provided and reviewed instead of relying only on information entered into an online form.
Lets run some numbers. I want to look at the estimated payment, funds needed at closing, and how much cash you want left after the purchase. A payment may technically fit a loan guideline but still be more than you want in your monthly budget.
Mistake 2: Making Credit Changes Before Closing
Your credit is not reviewed only at the beginning. Lenders may update credit information or verify new debts before closing.
Avoid financing furniture, buying a vehicle, co-signing for another person, or opening a new credit card without discussing it first. Even a payment that seems manageable can affect the debt-to-income calculation.
Also keep current accounts paid on time and avoid running balances higher. A change in credit score or monthly debt may change the loan terms or require the file to be reviewed again.
If something needs to be purchased, call or text your loan consultant before applying for credit. It is much easier to review the possible effect before the new account appears.
Mistake 3: Changing Jobs or Income Without a Review
A job change does not automatically prevent someone from getting a mortgage. The issue is how the new income is earned, when it starts, and whether it meets the loan program guidelines.
Moving from salary to commission, becoming self-employed, reducing hours, or changing to contract work may affect qualifying income. Bonuses, overtime, commissions, and other variable income commonly require a documented history.
Employment and income are typically verified again before closing. If you are considering a change, review it before giving notice or accepting a different compensation structure.
Mistake 4: Moving or Depositing Money Without Documentation
Lenders need to confirm where the money for the down payment, closing costs, and required reserves came from. Regular payroll deposits are generally easy to identify. Large cash deposits, account transfers, sale proceeds, and gift funds may require more documentation.
Cash can be especially difficult to document because there may not be a clear paper trail. Depositing cash shortly before or during underwriting does not always mean it can be used for the transaction.
Keep bank statements, transfer confirmations, sale records, and gift documentation. Do not move money through several accounts if there is no reason to do it. A clean paper trail helps the lender verify that the funds are acceptable under the selected program.
Mistake 5: Assuming You Need 20% Down
A 20% down payment may avoid private mortgage insurance on a conventional loan, but it is not the only option. Depending on current program and lender requirements, some conventional loans may offer low-down-payment options, while FHA, VA, and USDA financing may also offer reduced- or no-down-payment structures for eligible borrowers. Terms and eligibility vary, so consult a licensed mortgage professional.
Each program works differently. Mortgage insurance, eligibility, property requirements, location rules, and credit standards vary. Buyers can review low down payment purchase options before deciding how much cash to use.
Putting more money down may lower the payment, but it also leaves less money available after closing. I recommend comparing several choices and keeping repairs, moving expenses, and emergency savings in the discussion.
Mistake 6: Comparing Only the Interest Rate
The rate is important, but it is only one part of the mortgage. Buyers should also compare points, lender fees, mortgage insurance, loan type, term, and estimated cash needed at closing.
A lower rate may require points paid upfront. That can make sense in some situations, but not every situation. The time you expect to keep the mortgage matters because it may take time for the monthly savings to recover the upfront cost.
The annual percentage rate, loan estimate, and total closing costs provide more context than the note rate alone. Review the same loan amount and similar structure when comparing offers.
A fixed-rate mortgage keeps the principal and interest portion of the payment stable, while taxes, insurance, and association dues can still change. Other loan structures may have different payment features and should be reviewed carefully.
Mistake 7: Forgetting About Closing Costs and Reserves
The down payment is not the full amount needed to buy a home. Closing costs may include lender charges, title and escrow services, appraisal costs, prepaid interest, property taxes, and homeowners insurance. The exact items vary by lender, property, location, and loan program.
Some buyers may be able to negotiate a seller credit, depending on the contract and program limits. A lender credit may also be available in exchange for different pricing. Neither choice is automatic, and both should be reviewed with the full transaction.
I also recommend keeping some money available after closing when possible. Using every available dollar can make normal ownership expenses harder to manage.
Mistake 8: Choosing a Loan Program Without Comparing Options
There is no single mortgage program that fits every first-time buyer. The right structure depends on credit, income, available funds, property type, military eligibility, and how long you expect to keep the loan.
| Loan Type | General Structure | Items to Review |
|---|---|---|
| Conventional | May offer low down payment choices and flexible property options. | Credit, mortgage insurance, down payment, and county loan limits. |
| FHA | Government-insured financing with a 3.5% minimum down payment under standard guidelines. | Mortgage insurance, property standards, and current loan limits. |
| VA | May provide 0% down financing for eligible borrowers. | Eligibility, entitlement, funding fee rules, and property requirements. |
| USDA | May provide 0% down financing in eligible locations. | Property location, household income limits, and program availability. |
As of 2026, guidelines, loan limits, fees, and market rates can change. An FHA home loan may work well for one file while conventional or VA financing may provide a better structure for another. The numbers have to be compared using the same purchase price and realistic closing cost estimates.
Mistake 9: Leaving Out Financial Information
It is important to discuss the complete financial picture at the beginning. That includes child support obligations, tax payment plans, student loans, co-signed debts, rental properties, self-employment, and recent credit events when they apply.
Leaving something out does not make it disappear. It may be found during credit review, income verification, bank statement review, or final underwriting.
Early disclosure gives the loan consultant time to review the guideline and request the right documents. It also reduces the chance of a last-minute change in the loan structure.
Mistake 10: Not Reading the Loan Estimate
The Loan Estimate shows important details about the proposed mortgage, including the loan amount, rate structure, projected payment, closing costs, and whether certain terms can change.
Review the document instead of looking only at the cash-to-close figure. Ask about points, lender credits, mortgage insurance, escrow accounts, and any item you do not understand.
No surprises later, here is what I can offer you. I will review the choices, explain how the numbers were calculated, and show where an estimate could change based on the property or final transaction details.
A Simple First-Time Buyer Mortgage Checklist
- Complete a full pre-approval before making an offer.
- Provide current income and asset documents.
- Keep making every debt payment on time.
- Do not apply for new credit without a review.
- Keep down payment funds in documented accounts.
- Compare loan programs, points, fees, and estimated payments.
- Budget for closing costs and money needed after closing.
- Report employment, income, debt, or asset changes promptly.
- Review the Loan Estimate and ask questions.
- Verify current rates, fees, and program guidelines with a lender.
Review Your Mortgage Plan Before You Make an Offer
A good first step is to review the complete scenario before shopping seriously. I can look at your income, credit, available funds, estimated payment, and possible loan programs without assuming one option will work better than another.
If you are buying in Multnomah County or another area I serve in Oregon or Washington, call, text, or email Mortgage Solutions NW. We can compare options, discuss pre-approval planning, and make sure you understand the next steps before you write an offer.
Frequently Asked Questions
Can gift funds be used for a first home purchase?
Gift funds may be allowed for some or all of the down payment and closing costs, depending on the loan program. The lender will typically need a gift letter and documentation showing the transfer of funds. Donor and borrower requirements vary, so review the gift before moving money.
What happens if the appraisal is lower than the purchase price?
A low appraisal may require the price, loan amount, or cash contribution to be reviewed. The parties may renegotiate, challenge the appraisal with supporting information, or consider other contract options. The available choices depend on the loan program and purchase agreement.
How long are mortgage documents considered current?
Pay stubs, bank statements, credit reports, and other documents have program-specific age requirements. Updated documents may be requested if the purchase or closing takes longer than expected. Continue saving statements and employment records until the loan closes.
Can a self-employed first-time buyer qualify for a mortgage?
Self-employed buyers may qualify when their income, credit, assets, and property meet the selected program guidelines. Lenders commonly review tax returns, business information, and current income documentation. Bank statement or other non-QM programs may also be considered when standard documentation does not fit the scenario.
Should a first-time buyer waive the financing contingency?
Waiving a financing contingency can increase financial and contractual risk if the mortgage is delayed or not completed. A pre-approval does not remove every underwriting, appraisal, title, or property condition. Review the decision with your real estate and mortgage professionals before changing contract protections.
This is educational and not financial advice. Loan programs and guidelines can change. Talk with a licensed mortgage professional about your specific scenario.
