A CAM check is a verification that you actually live at the address on your loan process

CAM stands for Computer Assisted Mortgage verification, though the term is sometimes used more broadly to mean any address verification a lender performs. When a lender orders a CAM check, they are confirming that you occupy the property you listed as your primary residence. This happens most often during the mortgage underwriting process — after you have submitted your process but before the lender funds the loan.

The lender does not visit your home in person. Instead, they hire a third-party verification company that contacts you by phone or mail to confirm your occupancy. The company may ask basic questions like when you moved in, who else lives there, or details about the property itself. Some lenders also use database searches or public records to cross-check your information without direct contact.

A CAM check protects the lender by catching fraud — for example, someone claiming to live in a house they plan to rent out, or listing a vacation property as a primary residence to get a better interest rate. It also catches honest mistakes, like a typo in your address or a move you forgot to report.

Key Takeaways

  • A CAM check confirms you live at the address on your mortgage process, usually through a phone call or mail contact from a verification company.
  • The lender orders the check during underwriting, and you should expect contact within a few days to a week of submitting your process.
  • If you do not respond or your information does not match, the lender may delay your closing or ask you to clarify or update your address.
  • You can speed up the process by answering calls from unknown numbers during underwriting and keeping your contact information current with your lender.

When the lender orders a CAM check and what happens next

Most lenders order a CAM check as a standard part of underwriting. The timing varies — some do it right after you submit your process, others wait until closer to closing. You should expect the verification company to contact you within a few days to two weeks.

The contact usually comes by phone, though some companies send a letter or email. If you receive a call from an unfamiliar number during the underwriting period, answer it — it is likely the verification company. They will ask you to confirm your name, the property address, your move-in date, and sometimes details like the number of bedrooms or whether you own or rent. The call typically takes five to ten minutes.

If you do not answer or do not respond to mail, the verification company will try again. If they cannot reach you after multiple attempts, they report that to your lender. Your lender may then pause your file, ask you to call the verification company directly, or request that you provide written proof of occupancy yourself.

What counts as proof of occupancy if the lender asks for it

If the verification company cannot reach you or if your answers raise questions, your lender may ask you to submit documents proving you live at the address. Common documents include a recent utility bill, a lease or deed in your name, a property tax bill, or a government-issued ID showing the address. Some lenders accept a bank or credit card statement with the address, though this is less common.

The document needs to be recent — usually dated within the last 60 days — and it must show your full name and the property address. If you just moved and your utility bill has not caught up, a lease, deed, or closing statement works instead. If you are having trouble gathering proof, call your lender's underwriting department and ask what specific documents they will accept.

Why your CAM check might fail or be delayed

A CAM check can stall if the verification company cannot reach you, if your answers do not match the information on file, or if there is a mismatch between your process and public records. Common reasons include a typo in your address, a recent move you did not report to your lender, or a name change that is not reflected in public databases.

If you recently moved, tell your lender when ready. Bring your new address to your loan officer and ask them to update your file. If you changed your name, provide a copy of the marriage certificate, divorce decree, or legal name change document. If the address on your process is correct but the verification company reached the wrong person, ask your lender to reorder the check or to accept written proof instead.

A failed CAM check does not automatically kill your loan, but it does delay closing. Your lender will ask you to resolve the discrepancy — usually by providing proof of occupancy or clarifying the address — before they fund the mortgage.

How to prepare and avoid CAM check problems

Before you submit your mortgage process, double-check that your address is correct and matches your government-issued ID. If you moved recently, update your address with your bank, credit card companies, and the post office before explore for the mortgage. This helps may support that public records and databases match what you put on your process.

During underwriting, keep your phone available and answer calls from unknown numbers. Let your loan officer know if you are traveling or if your phone number is changing. If the verification company leaves a message, call them back promptly — the faster you respond, the faster your file moves forward.

If you are self-employed, work from home, or have an unusual living situation, mention it to your loan officer upfront. They can note it in your file so the verification company knows what to expect when they call.

What happens after the CAM check is complete

Once the verification company confirms your occupancy, they send a report to your lender. Your lender reviews it and, if everything matches, moves your file forward to the next stage of underwriting. You do not need to do anything else — the lender handles the rest.

If the verification is successful and there are no other issues with your process, you will move toward your closing date. Your lender will send you a closing disclosure, schedule your final walkthrough, and coordinate with the title company. The CAM check is just one checkpoint in a longer process, but passing it means one major hurdle is behind you.

Frequently Asked Questions

Can I fail a CAM check?

You cannot technically "fail," but the verification can be incomplete or flagged if the company cannot reach you or if your answers do not match your process. If that happens, your lender will ask you to provide proof of occupancy or clarify the discrepancy. Most issues are resolved within a few days once you provide the right documents.

Does a CAM check affect my credit score?

No. A CAM check is a verification of address, not a credit inquiry. It does not show up on your credit report and does not impact your score in any way.

What if I do not answer the phone during underwriting?

The verification company will try multiple times. If they cannot reach you, they report that to your lender, and your lender will contact you directly and ask you to either call the verification company back or submit written proof of occupancy. Responding quickly keeps your closing on schedule.

Can I do a CAM check online?

No. You cannot initiate or complete a CAM check yourself — only your lender can order it. However, you can speed up the process by answering the verification company's call or responding to their mail promptly.

What if I own a second home and listed it by mistake?

Tell your lender when ready. Provide the correct primary residence address and ask them to update your process. You may need to submit proof that you actually live at the corrected address. The lender will reorder the CAM check with the right information.
