During underwriting, do nothing financially and do everything administratively: freeze your credit and spending, return every document request the same day, stay reachable, and keep your loan officer informed of any change in your job, income, or accounts until the funds fund.
Your Job During Underwriting Is Simple and Specific
Once your file is in underwriting, the work belongs to the lender, but your cooperation decides how fast it goes. Your job has two parts: change nothing financially and respond to everything instantly. That sounds easy, and it is, yet more closings are delayed by a careless week during underwriting than by any single dramatic event.
The reason is that the underwriter is verifying that the buyer who applied for the loan is the same buyer who will show up at closing. Every purchase, new account, job change, or unexplained deposit in your bank account has to be explained, and explanations take time. Keep the picture steady and you keep the loan on schedule.
Freeze Your Finances, in Plain Language
Between the signed contract and settlement, treat your financial life as a still photograph. Do not open new credit cards, finance furniture, lease a car, or co-sign anything. Do not take out a personal loan or move large sums between accounts. Keep your bank balances stable and avoid deposits that cannot be traced, like a stack of cash or a check from an unusual source.
If you must make a purchase on credit, even a small one, check with your loan officer first. If you receive a large gift, ask about the correct way to document it before it lands in your account. The lenders' final credit pull happens close to closing, so a card opened in week three of underwriting can surface in week six, right when nobody wants surprises.
Respond Fast, and Respond Completely
The document requests during underwriting feel repetitive: another pay stub, an updated bank statement, a letter of explanation, a signature page. Treat each request as urgent: return it the same day, fully completed, in the format the lender asked for. A partially filled form or a missing page starts the clock over on that condition, and underwriting timelines are made of dozens of small turnarounds.
Keep your documents in one folder, digital and paper, from the day you apply. When the lender asks for an updated statement, you should already know where to find it. If you are traveling or closed a bank account, say so early. The buyers who treat underwriting like their most important part-time job are the ones who hear the words 'clear to close' exactly on schedule.
Stay Reachable and Keep Your Agent in the Loop
Underwriters rarely call; they send requests through your loan officer. Check email and voicemail daily, return calls within hours, and pick up when your loan officer calls, because a question that sits for a day becomes a condition that sits for a week. If your lender uses a portal, check it mornings and evenings.
Keep your real estate agent informed of your loan progress, especially if a deadline is near, because your agent coordinates the contract timeline around the lender's milestones. If the lender tells you of a delay, your agent needs to know immediately so they can adjust inspection dates, extend deadlines in writing with the seller, or protect you against a missed deadline. Silence is the enemy of a smooth closing, so keep the communication channels open and active.
What Not to Do, Even in the Final Days
The most dangerous period is the last two weeks, because the loan feels done and buyers relax. The lender can re-verify employment and re-pull credit right up to funding, so the rules never truly end until the keys are in your hand. Do not quit your job, take a different role with different pay, or change pay structure 'temporarily.' Do not book a celebratory vacation on a new card, and do not move money around to 'make the account look better.'
If something genuinely changes, a promotion, a layoff, a medical leave, tell your loan officer and agent the same day. Lenders can often work with real changes when they hear about them early. What they cannot do is approve a loan while the buyer hides a material change and hopes nobody notices. Transparent buyers close; clever buyers get delayed.
Underwriting House Rules for Buyers
Live by these five rules from contract day to funding day:
- No new credit: no cards, no financing, no co-signing, no lease-to-own, nothing
- No large moves of money: keep deposits traceable and accounts stable
- Respond the same day: every document request, portal message, and signature, immediately
- Stay reachable: check email and voicemail daily, and answer your loan officer's calls
- Disclose changes instantly: a promotion, a layoff, a gift, anything material, tell the lender the same day
Treat the underwriting period as a quiet, administrative season: boring finances, fast paperwork, and open communication. The buyers who follow these five rules hear 'clear to close' on schedule, and the ones who break them learn why the rules exist.
