Article Summary

Underwriting is the process by which a mortgage lender evaluates a home buyer's mortgage application and determines whether the mortgage should be approved.

Underwriting: Explained in Plain English

Underwriting is a detailed evaluation of a borrower's ability to repay a loan.

An underwriter performs the underwriting of a mortgage, which may include verifying a home buyer's credit history, employment status, income, debts, and other characteristics of the transaction. This can include factors like the condition of the property and whether the transaction is an arms-length transaction.

Each mortgage type features different underwriting standards, known as mortgage guidelines. An FHA mortgage is underwritten differently than a USDA loan and a VA loan. A HomeReady mortgage is underwritten differently than a Home Possible mortgage.

As part of the underwriting sequence, an underwriter may check credit reports for payment history and outstanding debts, verify employment through recent pay stubs or contact the employer directly, and confirm income by examining tax returns and bank statements.

Additionally, an underwriter may review a property's value to ensure it aligns with the loan amount requested.

When underwriting is complete, the home buyer's mortgage application is marked approved or denied.


Underwriting: A Real World Example

Imagine a first-time home buyer applying for a low-downpayment mortgage to purchase a home.

The mortgage lender's underwriting sequence will include a review of the buyer's:

  1. Credit history
  2. Employment status
  3. Income and debts
  4. Property details

Underwriting may also require an appraisal of the subject property to ensure its value is commensurate with the purchase price, proof of a paid homeowners insurance policy for the upcoming 12 months, and a clean title report.

After every checkbox on the underwriting list is satisfied, the lender can issue a clear-to-close, indicating that the home buyer may schedule their closing.


When Underwriters Need Additional Documentation

During underwriting, if something in your application needs clarification - like an employment gap, large deposit, or credit issue - the underwriter may request a letter of explanation. This is your opportunity to provide context and help the underwriter understand your situation.
