I got a call once from a buyer three days before closing. She had just bought a new sofa, a dining set, and a bedroom set, all on a store credit card, because her new house had empty rooms and she was excited to fill them.
Her loan almost fell apart because of that sofa.
I have been in real estate for over 10 years, and I am also a photographer. I have sat through more closings and final walkthroughs than I can count, and I keep seeing the same handful of mistakes over and over. Most of them are not complicated. They come from excitement, or from simply not knowing the rules of this last stretch before you get your keys.
This guide walks through the mistakes that actually derail closings, the ones I have watched happen firsthand.
Why the Final Stretch Is So Dangerous
Once your offer is accepted and your mortgage lender starts underwriting your loan, you are in a strange in-between period. The house feels like yours already. It is not, not quite yet.
An underwriter is still reviewing your finances right up until closing day. They are not just checking a box once and walking away. Some lenders re-check your credit report and your debt-to-income ratio again just before closing. This means the financial decisions you make during this window can genuinely affect whether your loan actually goes through.
I tell every buyer the same thing during this stage. Treat your finances like they are frozen in ice. Nothing moves until you have keys in your hand.
Mistake 1: Buying Furniture or Appliances on Credit
This is the mistake that almost cost my client her sofa-loving heart a house.
New credit, even a store credit card for a bedroom set, changes your debt-to-income ratio. Lenders calculate this ratio using your existing debt against your income, and adding a new monthly payment, even a small one, can push you over the line they are comfortable with.
It gets worse. Many lenders pull your credit report again close to closing, specifically to check for new credit activity. A brand new furniture loan or a new credit card, even one with a zero balance today, can show up and trigger a second look at your entire application.
Wait until after closing to buy anything on credit. I know the empty rooms are tempting. Cash purchases are fine. Financed purchases are the danger.
Mistake 2: Changing Jobs Before Closing
I understand that career opportunities do not wait for your closing date. But changing jobs, even for better pay, can complicate your mortgage approval right when you need stability the most.
Your loan officer verified your income and employment when you applied. Most lenders verify it again close to closing, sometimes within days. A new job means a new employment history, and depending on the type of loan you have, that can trigger additional documentation requests or even a delay while the underwriter reviews the change.
If a job change is genuinely unavoidable, tell your loan officer immediately, not after the fact. They may be able to guide you through it without derailing your timeline, but only if they know in advance.
Mistake 3: Ignoring Emails About Wire Instructions
This is the one that keeps me up at night when I think about it, because the financial damage can be permanent and completely unrecoverable.
Wire fraud around closing has become alarmingly common. Scammers monitor real estate transactions, sometimes by hacking into email accounts involved in the deal, and send buyers fake wire instructions that look completely legitimate. The email might even come from what looks like your title company or escrow officer’s actual address.
Here is the rule that has zero exceptions. Never wire your closing funds based on emailed instructions alone. Always call your title company or escrow officer directly, using a phone number you find independently, not one listed in the email you just received. Confirm the wiring details verbally before you send a single dollar.
Once a wire transfer leaves your account, it is often gone within minutes. Banks and law enforcement can sometimes recover funds if you act within hours, but many buyers do not realize what happened until days later. By then, the money is usually gone for good.
Mistake 4: Skipping or Rushing the Final Walkthrough
The final walkthrough is your last chance to confirm the home is in the condition you agreed to before you legally take ownership. I have watched buyers treat this step like a formality, walking through in ten minutes just to check a box.
Here is how I approach it, using the same habits I use behind a camera. Slow down. Look at every room, not just the ones you remember loving.
Bring your phone and actually take photos, room by room, the same way you would document a scene for a shoot. Compare what you see against your original inspection report and any repairs the seller agreed to make. Open every faucet and flush every toilet. Test light switches in every room, including closets people tend to skip. Check that any appliances included in the sale are actually still there, since I have genuinely seen sellers swap out a nicer refrigerator for an old one during the move.
If repairs were promised, look closely at the actual work, not just whether something looks fixed at a glance. A patched water stain on a ceiling should come with a clear explanation of what caused it and whether the underlying issue was actually resolved.
If something is wrong, say something immediately, before you sign anything. Once you close, your ability to negotiate on these issues mostly disappears.
Mistake 5: Forgetting to Set Up Home Insurance in Time
Your mortgage lender will not let you close without proof of home insurance in place. This surprises more buyers than you would expect, mostly because it feels like a small detail compared to everything else happening.
Start shopping for home insurance at least two to three weeks before your closing date, not the week of. Get your policy details to your loan officer as soon as it is finalized, since this is one of the documents your lender needs before they will release your closing paperwork.
Mistake 6: Not Reviewing Your Closing Disclosure Carefully
Your Closing Disclosure lists your final loan terms, your closing costs, and how much money you need to bring to closing. Lenders are required to give you this document at least three business days before closing.
Do not treat those three days as a waiting period. Actually read the document, line by line, and compare it against the Loan Estimate you received earlier in the process. Numbers should be close to what you originally agreed to. If something changed significantly, ask your loan officer to explain exactly why before closing day arrives.
Mistake 7: Making Large, Unexplained Bank Deposits
Underwriters do not just look at your credit report. They often look at your bank statements too, checking for large deposits that do not match your normal income pattern.
A large unexplained deposit, even a completely honest one like a gift from a family member, can slow down your closing while the underwriter asks for documentation explaining where that money came from. If you know a large deposit is coming, whether it is a gift, a bonus, or money from selling something valuable, keep clear records and let your loan officer know in advance.
Mistake 8: Assuming Verbal Promises Are Enough
If a seller verbally agreed to leave the washer and dryer, or promised to fix a fence before closing, get it in writing. I cannot stress this enough after watching handshake agreements fall apart more times than I would like to admit.
Verbal promises are easy to forget, easy to deny, and nearly impossible to enforce once you have already closed. Anything important should be written into your purchase agreement or a signed addendum, not left as a friendly conversation between you and the seller.
Common Closing Mistakes and Their Consequences
| Mistake | Possible Consequence |
|---|---|
| Buying furniture or appliances on credit | Raises debt-to-income ratio, can delay or kill loan approval |
| Changing jobs before closing | Triggers new employment verification, possible delay |
| Wiring funds based on email instructions alone | Permanent loss of closing funds through wire fraud |
| Rushing the final walkthrough | Missed repairs or missing items go unnoticed until too late |
| Delaying home insurance shopping | Lender may refuse to close without proof of coverage |
| Skimming the Closing Disclosure | Overlooked cost changes or errors go unquestioned |
| Large unexplained bank deposits | Underwriter delays closing pending documentation |
| Relying on verbal seller promises | Agreements become unenforceable after closing |
Quick Reference Checklist
In the final weeks before closing, run through this list:
- Do not open any new credit cards or loans, even for furniture
- Avoid large purchases on existing credit cards
- Tell your loan officer immediately about any job changes
- Never wire money based on emailed instructions alone, always call to confirm
- Slow down during your final walkthrough, and take photos room by room
- Test faucets, toilets, switches, and confirm included appliances are present
- Start shopping for home insurance two to three weeks before closing
- Read your Closing Disclosure line by line, not just skim it
- Document the source of any large bank deposits in advance
- Get every seller promise in writing, never rely on a verbal agreement
Final Thoughts
The last few weeks before closing feel like the finish line, and in a way, they are. But this is also exactly when small mistakes carry the biggest consequences, simply because there is so little time left to fix them.
Slow down during this stretch. Treat your finances carefully, verify everything in writing, and look at your final walkthrough the way you would look through a camera lens, checking every corner instead of just glancing around the room.
That little bit of caution, right at the very end, is what actually gets you to the closing table with your deal still intact.
