The 90-day camera (your bank statements are being watched)

When you apply for a mortgage, the lender asks for your last 90 days of bank statements. Then they read every line. Every deposit. Every transfer. Every big number.

This is the 90-day camera. It is always rolling. Most people do not know it exists until it is too late.

What lenders look for

Lenders need to know two things about your down payment money:

• Is this money really yours? Not borrowed. Not from a source they cannot check.
• Where did it come from? Every big deposit needs a story on paper.

A "big deposit" is not that big. Anything unusual for your account. A $2,000 e-transfer when you normally see $100 e-transfers is unusual. A $5,000 cash deposit is very unusual. Even $10,000 moving between your own accounts can raise a flag if the story is not clear.

A true story

A first-time buyer we know sold an old couch on Facebook Marketplace. The buyer paid $3,000 in cash. She deposited it. Two weeks later, she was mid-application on her dream townhome.

The lender saw the $3,000 cash deposit. They asked where it came from. She said, "A couch." They asked for proof. She had no receipt. No message trail. No listing screenshot. Just the couch.

Her approval paused for two weeks while she chased the buyer for a message. Two weeks of stress. Two weeks of the seller getting nervous. It worked out. But it did not have to be that hard.

Deposits that always need paperwork

The plan: move early, sit still

The rule is simple. Any big money that will help with your down payment should be in your account and calm for at least 90 days before you apply.
