Can I switch lenders after pre-approval?
Want to change lenders after pre-approval? Read this first — it will save your deal.
Short answer
Yes. You can switch lenders after a mortgage pre-approval. Pre-approval is not a legal lock on you. It is a lender’s conditional promise based on the documents and credit at that time. Switching is possible but requires care to avoid delays, extra costs, or a hit to your credit score.
What actually changes when you switch lenders
- New application and underwriting: The new lender runs its own checks and may require updated documents, a new appraisal, or different income verification.
- Credit inquiries: Expect another hard credit check. Good news: rate-shopping within a 14–45 day window usually counts as one inquiry for scoring models, but confirm with your mortgage broker.
- Rate and fees: A better interest rate or lower fees can make switching worth it. Always compare the full cost: interest, origination fees, appraisal, and legal fees.
- Timelines and contingencies: A new lender can delay conditional approvals and push your closing date. If your purchase offer has tight deadlines, switching can jeopardize the deal.

Smart step-by-step process to switch lenders safely
- Compare offers side-by-side. Look at effective interest rate, fees, prepayment options, and penalty terms. Don’t focus on rate alone.
- Get a written rate quote and ask about rate locks. Pre-approval rarely locks a rate; a rate lock does.
- Check credit impact. Plan your applications within a short window and ask lenders to avoid unnecessary hard pulls until you decide.
- Coordinate timelines. Tell your real estate agent and the seller’s lawyer about the change to avoid surprise delays.
- Withdraw the original application once you have an approved mortgage commitment from the new lender. This prevents duplicate processing fees.
When you should not switch lenders
- Days from closing: Last-minute switches often cause failures. If closing is within 1–2 weeks, avoid switching unless there’s an emergency.
- Weak documentation: If your income or down payment documentation changed or is thin, a second lender may deny you.
- Minimal savings: If the savings from a lower rate don’t cover legal or appraisal costs, don’t switch.
