Documentation, and why it is asked for

A mortgage is a large loan that will be sold on to an investor. That investor needs the file to be complete and verifiable. The documents are how the file proves what it claims.

So when a lender asks for two years of tax returns, they are not suspicious of you personally. They are satisfying a requirement that exists for every loan of that kind.

For most people, the starting set is: government photo identification, your Social Security number, recent pay stubs, the last couple of years of tax returns, and recent bank statements for the accounts you are using.

Depending on your situation, additional items come into play — business returns if you are self-employed, a gift letter if family is helping, proof of your current address if it differs from your identification, and a Certificate of Eligibility if you are using VA benefits.

It feels excessive to hand over every page of a bank statement. The reason is that the pages carry the detail — deposits, transfers, balances — and a partial statement cannot be verified.

The same logic applies to tax returns. All pages and all schedules, not just the summary page, because the details on the schedules are part of what gets reviewed.

Start earlier than you think you need to. Gather the documents into one place — a folder, physical or digital — and add to it as you go rather than all at once at the end.

And ask for your own list rather than using a generic one. Someone using VA benefits, someone self-employed and someone buying with family help do not hand over identical paperwork. A list built for your situation saves you collecting things you will never need.
