A prequalification letter is only as strong as the work done before it’s issued.
A prequalification is typically an upfront review of income, assets, credit, and monthly obligations to determine what may realistically work.
A preapproval is generally a fully underwritten conditional approval—minus the property itself.
The tradeoff is that a preapproval is usually tied to a specific lender and product set, while a prequalification can allow more flexibility while exploring options.
As a former underwriter and auditor, my approach to prequalifications is heavily focused on precision.
Income should be calculated the way the final investor and underwriter are actually going to use it—not estimated, averaged incorrectly, or guessed.
Assets should be reviewed for large deposits, undisclosed debt, and documentation issues before they become problems later.
That perspective helps structure the file with the final review in mind, which can lead to fewer surprises and a smoother overall process once a loan officer issues the prequalification letter.
