Mortgage preapproval checklist

Lenders ask for documents so they can verify identity, income, assets, debts, and credit. Requirements vary by loan program and employment type. A salaried employee may provide different documents than a self-employed buyer, contractor, business owner, or buyer using gift funds.

Keep documents organized in a secure folder and avoid sending sensitive information through unprotected channels. If a lender portal is available, use the lender's instructions. Do not send full account numbers, tax records, or identity documents to anyone unless you have verified the recipient and the method is appropriate.

A lender may evaluate gross monthly income, monthly debt payments, credit history, available funds, reserves, loan-to-value ratio, property type, occupancy, and debt-to-income ratio. Some buyers focus only on the home price, but the lender is reviewing the full loan scenario.

Your personal comfort level can be more conservative than a lender's maximum approval. A maximum approval amount may not leave room for childcare, medical costs, retirement savings, commuting, repairs, travel, or other priorities. Treat preapproval as one input, not as an instruction to spend the maximum.

A lower monthly payment is not always the cheapest or best scenario. Points, lender credits, rate locks, APR, origination fees, underwriting fees, third-party costs, and escrow assumptions can shift the total cost. If two lenders use different assumptions, the comparison may be misleading.

Ask each lender to price the same scenario. For example, use the same purchase price, down payment, loan type, credit score assumption, occupancy, lock period, and estimated closing date. Then compare rate, APR, points, cash to close, and monthly payment line by line.

Mortgage files can be sensitive to changes. A new car loan, credit card, personal loan, job change, large deposit, cash transfer, co-signed debt, or missed payment may affect underwriting. Even when a change is harmless, the lender may need documentation.

If something changes, tell your lender promptly. It is usually better to explain early than to have a surprise appear shortly before closing. Keep records for transfers, gifts, bonus income, commission income, and account movements.

A preapproval letter can look simple, but the assumptions behind it matter. Ask what has been verified, what remains conditional, how long the letter is valid, and whether the lender has reviewed income, assets, credit, and debts.

Also ask what property types or situations may create extra requirements. Condos, multi-unit properties, homes needing repairs, flood zones, rural properties, manufactured homes, and new construction can involve rules that differ from a standard single-family purchase.
