A prequalification is an estimate based mostly on what you tell a lender. A preapproval usually means the lender has pulled your credit and checked documents like pay stubs, W-2s and bank statements. Neither is a loan commitment, and there's no federal rule that defines either word, so the label matters less than what was actually reviewed. The Consumer Financial Protection Bureau says it directly: lenders use the terms differently, and the word on the letter doesn't tell you much about the lender's process (CFPB). For a Texas offer, the strongest letter is the one backed by verified credit, income and assets, with only the property left open.
A prequalification turns a first conversation into an estimate. You share income, debts, savings and the price range you're considering, and the loan officer runs rough numbers against a program. Sometimes credit is pulled. Sometimes your own description of your credit is used.
Its value is speed. In one conversation you learn which programs are worth exploring, what down payment might be needed, and which questions will matter later, like how a bonus or a side business will be counted. Its limit is that little has been verified. Income that sounded steady may turn out to vary. A forgotten debt may appear on the credit report. A deposit may need a source.
A preapproval goes further. You complete an application, the lender pulls credit with your authorization, and documents are reviewed. For a salaried borrower that's typically recent pay stubs, W-2s and bank statements. For a self-employed borrower it may be tax returns or another documentation method the program allows.
Often the file is also run through an automated underwriting system: Fannie Mae's Desktop Underwriter, Freddie Mac's Loan Product Advisor, or FHA's TOTAL Mortgage Scorecard through an approved system. The findings say whether the profile fits that program's model and which documents an underwriter will need. Findings are system output. A human review of the documents is a separate step. See automated underwriting.
Even though "preapproval" isn't a defined term, a few federal rules come into play:
Even the strongest preapproval is conditional. A letter written before you have a contract can't cover:
A well-written letter says it's subject to those items. That's accurate, and it protects everyone.
Most financed Texas resales use the TREC Third Party Financing Addendum, TREC No. 40-11. Its Paragraph 2A, Buyer Approval, lets the contract be subject to you obtaining approval of your assets, income and credit within a number of days you fill in. If you can't get Buyer Approval in that window, you can terminate by giving the seller notice and a copy of the lender's written statement of the reasons, and the earnest money is refunded. If you don't terminate within that time, the contract is no longer subject to Buyer Approval (TREC 40-11).
That's where a strong preapproval helps. If credit, income and assets have already been reviewed, you can write a shorter Buyer Approval period, or check the box that the contract isn't subject to Buyer Approval at all, with much less risk. Paragraph 2B, Property Approval, is separate and covers the appraisal, insurability and lender-required repairs. See the Texas option period for how the other deadlines run.
A preapproval is a snapshot. The file is checked again before closing, and changes in between can change the answer:
Lenders verify employment close to closing and often refresh credit or check for new debt. A letter that's months old reflects facts that may have moved. If your search runs long, ask for the file to be refreshed before a new offer goes in. A preapproval also leaves the rate open. The rate is set when you lock, usually once you have a contract.
There's no federal expiration date for a preapproval letter. What expires are the documents behind it. Credit reports, pay stubs and bank statements each have a maximum age under the loan program, and the lender has to have current versions before closing. In practice, a letter is only as good as the newest documents in the file. If you've been shopping for a while, expect to send updated pay stubs and statements, and possibly have credit re-pulled, before a new offer or once you're under contract.
Some files need more than a standard review to produce a letter that means something: self-employed income, recent job changes, commission or bonus income, a co-borrower who won't live in the home, gift funds, past bankruptcy or foreclosure, or a plan to use down payment assistance. These don't stop you from getting preapproved. They just mean the letter should be written after those items are documented, not before, so it doesn't fall apart in underwriting.
A listing agent who calls about your letter usually wants to know three things: what was actually reviewed, whether anything is unresolved, and whether the contract timeline is realistic. With your permission, I can answer those in general terms. Your detailed financial information stays private.
This example is made up. Two buyers write offers on the same Keller home the same weekend. Buyer A has a letter from a phone call with stated income and no documents. Buyer B's letter was issued after credit was pulled and pay stubs, W-2s and two months of statements were reviewed, with a note that only the appraisal, title, insurance and final underwriting remain. Both letters say "preapproval." Buyer B can write a short Buyer Approval period in the financing addendum because the borrower side has been tested. Buyer A is really carrying a prequalification under a stronger heading.
Once you're under contract, the preapproval becomes the starting point for the real file. You get a Loan Estimate for the property, decide when to lock, and the appraisal is ordered through the lender's process. The title company opens its file and you bind homeowners insurance. The underwriter then reviews everything and usually issues an approval with conditions. When those are cleared, the lender issues clear to close, the Closing Disclosure goes out, and its waiting period runs before you sign. A preapproval built on complete documents tends to move through those steps with fewer surprises. See how underwriting works.
Want a letter that holds up when a listing agent calls? I'll review your actual documents up front and tell you exactly what's verified and what's still open, so your offer and your Buyer Approval deadline match reality. Schedule a call, or when you're ready, start an application.
