Getting pre-approved for a mortgage is exciting.
Getting under contract is even more exciting.
But once you are in the loan process, you are not done yet.
A lot still has to happen before settlement.
Your lender still needs to verify your income, credit, employment, assets, debts, bank statements, appraisal, insurance, and final loan conditions.
That means your financial decisions matter all the way up to closing.
One mistake during the loan process can create stress, delay settlement, change your approval, increase the cash you need, or in the worst case, cause the loan to fall apart.
That is why buyers need to know what to do and what not to do while they are buying a home.
This guide will walk you through the most important do’s and don’ts during the mortgage loan process.
Why the Loan Process Matters
A pre-approval is important, but it is not the same as being fully cleared to close.
When you are pre-approved, the lender has reviewed enough information to believe you may qualify for a loan.
But after you go under contract, the file goes much deeper.
The lender may review:
Credit
Income
Employment
Bank statements
Tax documents
Pay stubs
W-2s
1099s
Business income, if self-employed
Debt-to-income ratio
Down payment funds
Closing cost funds
Gift funds
Large deposits
Appraisal
Homeowners insurance
Title work
Property taxes
HOA information, if applicable
Final underwriting conditions
Until the lender gives final clear to close, buyers need to be careful.
Do: Stay in Close Contact With Your Lender
Your lender is one of the most important people in the transaction.
Respond quickly.
Check your email.
Answer calls.
Upload documents when requested.
Ask questions when something does not make sense.
The loan process can move fast, and delays often happen when buyers do not respond quickly to lender requests.
If your lender asks for something, do not ignore it.
Even if the request feels repetitive, there is usually a reason.
Underwriting may need an updated bank statement, explanation letter, pay stub, or document before the file can move forward.
Fast responses help protect your timeline.
Don’t: Open New Credit Cards
Do not open new credit cards during the loan process unless your lender specifically tells you it is okay.
Even a store credit card can create issues.
Opening new credit can affect your credit score, create a new inquiry, add a new account, and change your debt profile.
That can affect loan approval.
This includes:
Furniture store cards
Appliance store cards
Credit cards
Retail cards
Buy-now-pay-later accounts
Promotional financing
Personal lines of credit
That 10% discount at checkout is not worth risking your mortgage approval.
Wait until after closing.
Do: Ask Your Lender Before Making Financial Changes
If you are thinking about doing anything financial, ask your lender first.
This includes:
Moving money between accounts
Paying off debt
Opening credit
Closing credit
Changing jobs
Making large purchases
Depositing cash
Receiving gift funds
Selling assets
Co-signing for someone
Changing bank accounts
Changing insurance
Changing marital status on documents
Taking a leave of absence
Some things may be fine.
Some may create problems.
The key is not guessing.
Ask before you act.
Don’t: Buy Furniture Before Closing
This is one of the most common mistakes.
You are excited.
You found the house.
You know where the couch will go.
The dining room needs a table.
The bedroom needs furniture.
The basement needs a sectional.
The deck needs patio furniture.
But do not finance furniture before closing.
Do not open a furniture account.
Do not put a large furniture purchase on a credit card.
Do not use buy-now-pay-later.
Do not drain your cash reserves.
Wait until after settlement.
The house is not yours until it closes.
Don’t: Buy a Car
Do not buy or lease a vehicle during the loan process unless your lender has approved it in writing.
A new car payment can seriously affect your debt-to-income ratio.
Even if you think you can afford it, the lender has to calculate it under mortgage guidelines.
A new auto loan can affect:
Credit score
Monthly debt
Loan approval
Interest rate
Cash needed
Underwriting conditions
If your car dies during the loan process, call your lender before making any move.
Do not assume it will be okay.
Do: Keep Paying Your Bills on Time
This seems obvious, but it is critical.
Keep paying all bills on time.
That includes:
Credit cards
Car loans
Student loans
Personal loans
Existing mortgage
Rent
Utilities
Phone bill
Medical payment plans
Any other debt
A late payment during the loan process can create serious problems.
Even one late payment can affect your credit and approval.
Set reminders if needed.
Do not get so focused on the home purchase that you forget normal bills.
Don’t: Make Large Unexplained Deposits
Large deposits can create underwriting questions.
The lender may need to verify where the money came from.
This is especially important if the deposit is cash.
Lenders need to know that your funds are legitimate and not borrowed money that creates additional debt.
Before depositing a large amount, talk to your lender.
Examples that may need explanation include:
Cash deposits
Money from family
Sale of personal property
Business deposits
Transfers from another account
Venmo or Cash App transfers
Bonus income
Reimbursements
Tax refunds
Settlement proceeds
Gift funds
If the money is legitimate, that is fine.
But the lender may need a paper trail.
Do: Keep a Paper Trail
Documentation matters.
If money is moving, keep proof.
This may include:
Bank statements
Deposit slips
Gift letters
Transfer records
Sale receipts
Pay stubs
Bonus documentation
Tax refund records
Account statements
Retirement account statements
Explanation letters
Underwriting is documentation-heavy.
The cleaner your paper trail, the easier it is for the lender to verify your file.
Do not throw away documents.
Do not ignore requests.
Do not assume the lender will take your word for it.
They usually need proof.
Don’t: Move Money Around Randomly
Moving money between accounts can create extra underwriting work.
It may be completely fine, but it may require documentation.
If you transfer money from savings to checking, the lender may need to see both accounts.
If you move money from a business account to a personal account, the lender may need to verify it.
If you transfer funds from an investment account, the lender may need statements showing the source.
Before moving money, ask your lender how they want it handled.
The goal is to make the file clean, not complicated.
Do: Keep Your Job Stable
Employment matters.
If possible, do not change jobs during the loan process.
Do not quit.
Do not switch from W-2 to 1099.
Do not become self-employed.
Do not reduce your hours.
Do not move from salary to commission without talking to your lender.
Do not take an unpaid leave without talking to your lender.
A job change can be manageable in some cases, but it can also create delays or approval issues.
The lender needs to verify income and employment before closing.
If something changes, tell your lender immediately.
Don’t: Hide Job Changes
If your job changes, do not hide it.
The lender may verify employment close to settlement.
If they discover a change late, it can create a much bigger problem.
Tell your lender early if:
You changed jobs
Your pay structure changed
Your hours changed
You are taking leave
You lost your job
You accepted a new position
You are starting a business
You received a raise
You changed from salary to commission
You changed from W-2 to 1099
Surprises late in the loan process are bad.
Be upfront.
Do: Avoid New Debt
Do not take on new debt during the loan process.
Avoid:
Auto loans
Personal loans
Credit cards
Furniture loans
Appliance financing
Buy-now-pay-later plans
Co-signed loans
Boat or motorcycle loans
Equipment loans
Student loans, if avoidable
New business debt without lender guidance
New debt can affect your debt-to-income ratio.
Even if the payment seems small, it can matter.
Do not risk your mortgage for a purchase that can wait.
Don’t: Co-Sign for Anyone
Do not co-sign for someone during the loan process.
Even if you are just “helping,” the lender may count that payment against you.
Co-signing can affect your credit, debt-to-income ratio, and approval.
This includes co-signing for:
Car loan
Student loan
Apartment lease
Personal loan
Credit card
Business loan
Equipment loan
Wait until after closing.
Even then, be careful.
Do: Keep Your Credit Usage Stable
Try to keep your credit card balances stable or lower.
Do not run up credit cards.
Do not use cards for major purchases.
Do not max out a card.
Do not let balances spike.
Credit utilization can affect your score.
A lower score can affect your loan approval, interest rate, mortgage insurance, or conditions.
If you normally use a card and pay it off monthly, ask your lender how to handle it during the process.
Don’t: Close Credit Accounts Without Asking
Some buyers think closing accounts will help their credit.
Sometimes it can hurt.
Closing a credit card can affect your available credit, credit utilization, and credit history.
Do not close accounts during the loan process unless your lender tells you to.
If you want to clean things up, wait.
Your goal during the loan process is financial stability.
Not sudden changes.
Do: Save More Than You Think You Need
Buying a home usually costs more than buyers expect.
You may need money for:
Down payment
Closing costs
Prepaids
Escrows
Inspections
Appraisal
Moving
Utility setup
Repairs after closing
Furniture after closing
Tools and supplies
Insurance
Emergency fund
Do not drain every dollar just to get to closing.
If possible, keep reserves.
Owning a home comes with surprises.
Don’t: Spend Your Closing Money
Your lender is tracking whether you have enough money to close.
Do not spend the money you need for closing costs, down payment, or reserves.
This includes spending on:
Furniture
Appliances
Vacations
Wedding costs
Vehicles
Business expenses
Gifts
Large personal purchases
Debt payoff without lender guidance
The money needs to be there when it is time to close.
Do: Be Honest With Your Lender
Tell your lender the truth.
If something changes, tell them.
If you forgot to disclose a debt, tell them.
If you receive a large deposit, tell them.
If your job changes, tell them.
If your income changes, tell them.
If you are getting gift funds, tell them.
If you are worried about cash needed to close, tell them.
If you are unsure about anything, ask.
Mortgage problems are easier to solve early than late.
Don’t: Assume Pre-Approval Means Guaranteed Approval
Pre-approval is important.
But it is not a guarantee.
The lender still needs to verify the file and approve the property.
Things that can still affect approval include:
Appraisal
Title issues
Property condition
Employment verification
Updated credit
New debt
Missing documents
Bank statement issues
Insurance issues
Debt-to-income changes
Interest rate changes
Underwriting conditions
Do not treat pre-approval like the finish line.
It is the starting point.
Do: Review Your Loan Estimate
Early in the process, you should receive a Loan Estimate from your lender.
Review it carefully.
Look at:
Loan amount
Interest rate
Monthly payment
Estimated taxes
Estimated insurance
Mortgage insurance
Closing costs
Cash to close
Points
Escrows
Prepaids
Loan type
Whether the rate is locked
Ask questions if anything looks different than expected.
Do not wait until closing to understand your loan.
Don’t: Ignore Your Cash to Close
Cash to close is the amount you need to bring to settlement.
This number can change during the process as taxes, insurance, credits, seller assist, lender fees, title fees, and escrows are finalized.
Stay in communication with your lender.
Ask:
What is my estimated cash to close?
Has it changed?
Why did it change?
Does this include my deposit?
Does this include seller assist?
Does this include lender credits?
Are taxes and insurance final?
Are there any items still missing?
You should not be surprised by your final number at closing.
Do: Lock Your Rate When Appropriate
Mortgage rates can change.
Your lender can explain when and how to lock your rate.
A rate lock can protect you from rate movement for a certain period.
Ask:
Is my rate locked?
When does the lock expire?
What happens if closing is delayed?
Is there a cost to extend the lock?
Can the rate change?
Are points involved?
What is the APR?
What is my monthly payment?
Do not assume your rate is locked unless your lender confirms it.
Don’t: Change Insurance Without Communication
Homeowners insurance is part of the loan process.
The lender needs proof of insurance before closing.
Shop for insurance early.
Make sure coverage meets lender requirements.
If you change insurance companies, coverage amounts, deductibles, or policy details, tell your lender.
Insurance affects your monthly payment and escrow numbers.
Delays with insurance can delay closing.
Do: Respond to Underwriting Conditions Quickly
Underwriting conditions are normal.
They do not always mean something is wrong.
A condition simply means the underwriter needs something before final approval.
Examples may include:
Updated pay stub
Updated bank statement
Letter of explanation
Proof of earnest money deposit
Gift letter
Insurance binder
Tax transcript
Employment verification
Documentation of large deposit
Clarification of debt
Divorce decree
Child support documentation
Business income documents
Appraisal condition
Respond quickly.
The faster conditions are cleared, the smoother the process.
Don’t: Get Frustrated and Stop Communicating
The loan process can be annoying.
You may feel like the lender asks for the same thing more than once.
You may feel like the process is too detailed.
You may feel like underwriting is being picky.
That frustration is normal.
But do not stop communicating.
The lender is trying to document the file so the loan can close.
Stay calm.
Ask questions.
Keep moving.
Do: Keep Your Realtor Updated
Your agent does not need every private financial detail.
But your agent does need to know if there is a problem affecting the transaction.
Tell your agent if:
The lender needs more time
The appraisal is delayed
The lender has concerns
The closing date may be affected
You are worried about cash to close
You need seller assist adjusted
Insurance is a problem
You are not sure what the lender is asking
You may need an extension
Your agent can help coordinate communication with the listing side, but only if they know what is happening.
Don’t: Schedule Moving Too Aggressively
Do not assume closing is guaranteed until the lender gives clear to close and settlement is confirmed.
Avoid scheduling movers, utility shutoffs, or major commitments too tightly before final approval.
Sometimes closings get delayed because of:
Underwriting conditions
Appraisal delays
Title issues
Insurance problems
Final credit checks
Employment verification
Closing Disclosure timing
Seller issues
HOA documents
Repairs
Walkthrough concerns
Plan ahead, but stay flexible.
Do: Review Your Closing Disclosure Carefully
Before closing, you should receive a Closing Disclosure.
This document shows your final loan terms and closing costs.
Review it carefully.
Compare it to your Loan Estimate.
Look at:
Loan amount
Interest rate
Monthly payment
Cash to close
Closing costs
Taxes
Insurance
Escrows
Seller credits
Lender credits
Points
Loan type
Prepayment penalty, if any
Balloon payment, if any
Ask questions immediately if something looks wrong.
Do not wait until you are sitting at the settlement table.
Don’t: Ignore the Three-Business-Day Review Period
The Closing Disclosure matters.
The lender is required to provide it before closing so you have time to review.
If there are major changes, timing can be affected.
That is why buyers should be responsive and available as closing approaches.
Check your email.
Sign what needs signed.
Ask questions quickly.
Delays with final disclosures can delay closing.
Do: Avoid Large Cash Transactions
Avoid large cash deposits or withdrawals during the loan process.
Cash is hard to document.
The lender needs to verify funds.
If you are receiving money from family, selling something, or moving cash into your bank account, talk to your lender first.
A paper trail matters.
Don’t: Use Gift Funds Incorrectly
Gift funds may be allowed, depending on the loan type and lender rules.
But they need to be handled correctly.
The lender may require:
Gift letter
Donor information
Proof of transfer
Bank documentation
Confirmation it is not a loan
Timing requirements
Do not just have someone hand you cash.
Do not deposit gift funds without lender guidance.
Ask first.
Do: Keep Copies of Everything
Save copies of:
Contract
Addenda
Loan Estimate
Closing Disclosure
Pay stubs
Bank statements
Gift letters
Insurance binder
Inspection invoices
Appraisal invoice
Deposit proof
Repair receipts
Settlement documents
Wiring instructions
Communication with lender
You may need documents quickly.
Stay organized.
Don’t: Wire Money Without Verifying Instructions
Wire fraud is a serious risk in real estate.
Before wiring money, verify instructions through a trusted phone number.
Do not rely only on email.
Do not use a phone number from a suspicious email.
Call the title company or settlement company directly using a known number.
Be careful if you receive last-minute changes to wiring instructions.
That is a major red flag.
Protect your money.
Do: Ask About Final Walkthrough and Settlement Timing
As closing approaches, confirm:
Final walkthrough time
Settlement time
Location
Required identification
Final cash to close
Wiring instructions
Certified check rules, if applicable
Who needs to attend
Whether all lender conditions are cleared
Whether utilities need to be transferred
Whether homeowners insurance is active
Whether repairs are complete
The last few days can move quickly.
Stay organized.
Don’t: Make Big Life Changes Without Asking
During the loan process, stability is your friend.
Avoid major changes like:
Changing jobs
Starting a business
Taking unpaid leave
Opening new credit
Buying a vehicle
Moving large money
Co-signing debt
Changing banks
Taking out personal loans
Making large purchases
Draining savings
If life forces a change, communicate immediately.
But do not create unnecessary risk.
Do: Understand That the Lender May Recheck Things
Lenders may recheck credit, employment, funds, and other details before closing.
This is why buyers need to stay careful until settlement is complete.
Do not assume that because you were approved two weeks ago, new changes will go unnoticed.
They may come up before closing.
Protect your approval by keeping your financial picture steady.
Don’t: Celebrate Too Early Financially
Celebrate emotionally.
Do not celebrate financially until after closing.
You can plan furniture.
You can measure rooms.
You can make wish lists.
You can dream about renovations.
But do not spend the money yet.
After settlement, you can make decisions with confidence.
Before settlement, stay disciplined.
Common Loan Process Mistakes Buyers Make
Here are common mistakes buyers make during the loan process:
Opening new credit cards.
Buying furniture before closing.
Financing a vehicle.
Co-signing for someone.
Making large undocumented deposits.
Moving money without asking the lender.
Changing jobs without telling the lender.
Ignoring lender emails.
Spending closing funds.
Forgetting to pay normal bills.
Running up credit card balances.

Making major financial changes right before closing.
Most of these mistakes are avoidable.
A Simple Rule to Follow
During the loan process, follow this rule:

That simple rule can prevent a lot of problems.
Ask before you:
Buy
Borrow
Deposit
Transfer
Pay off
Open
Close
Co-sign
Change jobs
Move money
Accept gift funds
Your lender would rather answer a quick question upfront than fix a problem later.
