Mortgage Loan Do’s and Don’ts in Delaware

Mortgage loan do’s and don’ts are the financial moves you should make or avoid between application and closing to protect your credit, income, assets, and final loan approval. Reviewed by John R. Thomas, NMLS #38783.

If you are buying or refinancing a home in Delaware, the smoothest path to closing is mostly about not changing anything. I am John Thomas, and over more than 20 years helping Delaware buyers I have watched fully approved loans get delayed at the last minute over things the borrower never realized mattered: a new car payment, a furniture store credit card, a cash deposit with no paper trail. None of those people were doing anything wrong in normal life. They just did not know the loan process has its own set of rules. This guide gives you the top 10 do’s and the top 10 don’ts, plus the reason behind each one, so nothing catches you by surprise. If you have a question about your specific situation, call me at 302-703-0727 and we will talk it through.

New to the whole process? Start with our Delaware home buyer information guide for the big picture, then come back here for the do’s and don’ts that protect your approval.

What Should You Do During the Mortgage Loan Process?

These are the habits that keep an approval on track. None of them are complicated; they are about staying steady and staying in touch with your loan officer from application through closing.

1. Do stay current on every existing account. Pay all your bills on time during the loan process. Payment history is the single biggest factor in your credit score, and one 30-day late mark mid-process can lower your score enough to change your rate or your approval.
2. Do keep your financial records organized. Keep your most recent pay stubs and full bank statements (every page, even blank ones) handy. Underwriters ask for current copies as the file moves, and having them ready prevents delays.
3. Do ask questions and get educated on the process. The buyers who have the smoothest closings are the ones who understand what is happening and why. There is no such thing as a question that is too basic.
4. Do get pre-approved before you shop for a home. A pre-approval helps you understand your likely price range and makes your offer far stronger, because your income, credit, and assets have already been reviewed.
5. Do work with an exclusive buyer’s agent before you shop. A good agent representing you (not the seller) protects your interests through inspection, negotiation, and closing.
6. Do keep your employment and income consistent. Stability is what underwriting wants to see. Keep the same employer and the same income pattern through closing whenever you can.
7. Do call your loan officer with any question. If your finances change for any reason, tell me right away at 302-703-0727. The sooner we know about something, the more options we have to solve it.
8. Do get a home inspection from a licensed inspector. An inspection protects you from buying expensive problems and gives you leverage to negotiate repairs.
9. Do return requested documents within 24 hours. Responsiveness is often what decides whether a loan closes on time. When the lender asks, send it fast.
10. Do tell your loan officer everything up front. Past credit issues, a side business, a recent large deposit. Lenders verify nearly everything, so it is always better to disclose it early so we can plan for it.

What Should You Avoid During the Mortgage Loan Process?

Every item below has derailed real approvals. The common thread is change: anything that alters your credit, your income, or your bank balances between application and closing can force underwriting to re-evaluate your loan.

1. Don’t quit your job. Lenders typically verify your employment again within a day or two of closing. A gap or change can stop the loan cold.
2. Don’t apply for any new credit of any kind. A new credit inquiry and a new account both affect your score and your debt-to-income ratio. Wait until after you close.
3. Don’t pay off collections unless your loan officer tells you to. It seems helpful, but paying or closing an old collection can actually lower your score or restart its reporting clock. Ask first.
4. Don’t close credit card accounts. Closing a card reduces your available credit, which can raise your utilization ratio and drop your score, since amounts owed make up about 30% of a FICO score (payment history is the largest factor at 35%).
5. Don’t change jobs during the process. Even a better job can require fresh income documentation and a new approval. If a change is unavoidable, talk to me before you accept it.
6. Don’t shop for a home without a pre-approval letter. You risk falling for a house you cannot finance, and your offer is weaker without it.
7. Don’t make large undocumented deposits. No cash. Lenders must trace where your down payment and earnest money came from. A deposit with no paper trail (especially cash) can be excluded from your funds. If you are receiving help, follow the rules on our gift funds and gift of equity page.
8. Don’t transfer credit card balances. A balance transfer changes account balances and can affect your score during a sensitive window.
9. Don’t take cash advances on credit lines to buy the home. Borrowed funds for your down payment create exactly the documentation problem underwriting is screening for.
10. Don’t spend the money you need to close. Hold on to the cash you will need for your down payment and closing costs. Big purchases like a car or furniture can change your ratios and your available funds.

Why Do Lenders Re-Check Your Credit and Job Before Closing?

This is the piece most buyers do not expect, and it is the reason the don’ts above matter so much. Your approval is not a one-time snapshot. Shortly before closing, the lender confirms that nothing important has changed since you applied. Two checks are common:

• A verbal verification of employment. The lender contacts your employer, often within a day or two of closing, to confirm you are still employed.
• A soft credit re-check. Many lenders run a refresh that looks for new accounts, new inquiries, or higher balances opened after your application.

If that refresh shows a new car loan or a higher card balance, your debt-to-income ratio can change, and underwriting may have to re-approve the file. Once your file is “clear to close,” the smartest thing you can do is freeze your financial life until the keys are in your hand. Even on closing day, avoid scheduling deliveries or repairs that you would put on credit. Understanding how your full monthly payment is calculated can help here too; our guide to understanding your mortgage payment walks through principal, interest, taxes, and insurance.

What Should You Not Do Before Closing on a House?

Before closing, do not open new credit, change jobs, make large purchases, deposit unexplained cash, transfer funds without documentation, co-sign a loan, or miss a payment. Lenders re-verify your credit, employment, income, and assets right before closing, so the last few weeks are when discipline matters most. Federal rules build in checkpoints here: you must receive your Closing Disclosure at least three business days before closing (per the CFPB), and for most loans the lender completes a verbal verification of employment within 10 business days of your note date (per the Fannie Mae Selling Guide).

It helps to know where you are in the process, because the rules apply right up to closing day:

Step-by-Step Mortgage Process: When the Do’s and Don’ts Matter Most

1. Pre-approval. Get your documents in and your credit reviewed before you shop. Don’t open new accounts.
2. Under contract. Keep your income and accounts steady. Don’t make large or undocumented deposits.
3. Underwriting. Respond to document requests fast. Don’t change jobs or take on new debt.
4. Clear to close. Freeze everything. This is not the time to finance furniture or a car.
5. Closing day. Bring your ID and certified funds. Don’t schedule credit-based deliveries or repairs until after you have the keys.

What can I safely do after closing? Once the loan funds and you have the keys, you can buy furniture, open new credit, change jobs, or move money as you normally would. The do’s and don’ts on this page apply to the window between application and closing, not afterward. If you are unsure whether something can wait, the safe move is to call before you act.

What Documents Should You Gather Before You Apply?

Having your paperwork ready before you apply is one of the easiest ways to speed up your closing. For most buyers, plan to provide:

• Your two most recent pay stubs covering at least 30 days of income
• The last two months of statements for every bank, investment, and retirement account, including all pages
• Your W-2 forms (and 1099s, if any) for the past two years
• Your federal tax returns for the past two years
• A government-issued photo ID
• Documentation for any large or unusual deposit, plus a gift letter if you are receiving gift funds

If you are self-employed or paid mostly by 1099, your documentation looks different and there are specialized options such as a self-employed bank statement loan. Tell me how you are paid early, and we will build the right document plan for your situation.

What Are the Do’s and Don’ts for Self-Employed and 1099 Borrowers?

If you are self-employed or paid by 1099, the same rules apply, but a few extra ones matter because your income gets closer scrutiny. Do keep your business and personal banking clearly separated, keep your tax returns and year-to-date profit-and-loss current, and disclose every account up front. Don’t move money between business and personal accounts without a paper trail, take large owner draws right before closing, or make big undocumented deposits. If your tax returns don’t show enough qualifying income, ask about a self-employed bank statement loan or a 1099 mortgage loan program, which qualify you on deposits or 1099 income instead of tax returns.

How Do These Rules Affect Delaware and DSHA Buyers?

The do’s and don’ts apply to every loan type, but a few things matter specifically for Delaware buyers. If you are using a Delaware State Housing Authority program for help with your down payment, the same financial discipline protects your eligibility. A mid-process change to your income, your credit, your deposits, or the borrowers on the loan can affect how you qualify, including under the post-April-2025 income rule where Welcome Home counts only the income of borrowers on the note and mortgage. DSHA program rules can change, so we verify the current Welcome Home, Open Door, First State, Keys4You, Take5, and Diamond guidelines before you make any financial move during the loan process. If you are exploring assistance, see our Delaware down payment assistance programs overview, the DSHA Welcome Home first-time-buyer track, the DSHA Open Door track for repeat buyers, and the Keys4You down payment assistance page.

Two more Delaware notes. First, plan for closing costs that include the Delaware transfer tax; the standard Delaware Association of Realtors contract splits the 4% transfer tax equally, 2% to the buyer and 2% to the seller, but some home builders write their own contracts that require the buyer to pay the full 4%, so always read your contract. First-time buyers may qualify for a state transfer tax reduction. Second, whether you are looking at an FHA loan, a VA loan, or a conventional loan, the rules on this page protect your approval the same way. New to buying in Delaware? Our Delaware first-time home buyers guide ties it all together.

Safe Moves vs. Moves That Can Delay Your Loan

Safe to do during your loan	Wait until after closing
Pay every bill on time	Opening a new credit card or auto loan
Keep the same job and income	Quitting or changing jobs
Keep saving for closing costs	Large purchases (car, furniture, appliances)
Send documents quickly when asked	Large undocumented or cash deposits
Keep existing accounts open and active	Closing credit cards or paying off collections
Document any gift funds with a gift letter	Transferring balances or taking cash advances

Common Mortgage Myths vs. Facts

Myth	Fact
Paying off an old collection always helps my approval.	It can lower your score or restart reporting. Ask your loan officer before paying anything off.
Closing an unused credit card boosts my score.	It usually raises your utilization ratio and can drop your score during the loan.
A pre-approval means I’m fully approved.	Final approval is subject to underwriting and a credit and employment re-check before closing.
A small furniture purchase won’t matter.	A new monthly payment changes your debt-to-income ratio and can delay or derail closing.
Cash I deposit counts as my own funds.	Undocumented cash can’t be sourced and may be excluded from the money you use to close.

Bottom line: follow these mortgage do’s and don’ts whether you are buying your first home, a move-up home, or refinancing. If you want to get pre-approved or talk through your situation in Delaware or Maryland, call the John Thomas Team at 302-703-0727 or apply online.
