Conventional Loan Requirements: What Customers May Need to Document

Last reviewed October 5, 2026. Opened four authoritative primary-source pages. This article is general education and not a commitment to lend, approval, rate quote, legal advice, tax advice, or individualized financial advice.

Current information to know

The CFPB defines a conventional mortgage as a loan that is not part of a specific government program; conforming loans have government-set maximum loan amounts and additional rules set by Fannie Mae or Freddie Mac, while non-conforming loans are less standardized and can vary widely by lender. Read the applicable official guidance at consumerfinance.gov.

• ▸A lender generally documents and verifies income, employment, assets, debts, and credit history when assessing the customer’s ability to repay. This is an underwriting process, not a guarantee of approval.
• ▸Fannie Mae’s consumer education page says conventional loans may be fixed-rate or adjustable-rate and that an adequate down payment is part of the general profile; it gives 3% as an example of how low a down payment may be for some conventional loans, not a universal requirement or eligibility promise.

How to prepare

• ▸What a conventional loan is: distinguish conventional from government-program loans and briefly explain conforming versus non-conforming.
• ▸What lenders generally review: income, employment, assets, debts, credit history, the customer’s ability to repay, and transaction-specific information.
• ▸Down payment and mortgage insurance: explain that requirements vary; note CFPB’s typical less-than-20%-down mortgage-insurance point without presenting it as universal.

Use current documents and disclosures

Ask which current product or program applies, what documents are needed, how the lender will evaluate the transaction, and which written disclosures show the actual costs and terms. Compare written information carefully and consult an appropriate professional for legal, tax, or other individualized questions.
