After you get pre-approved for a mortgage, you can start house hunting with more confidence and clarity. You can use your pre-approval letter as a bargaining tool when making an offer, and show it to your real estate agent, who can help you find homes that match your criteria and budget. However, you should also keep in mind that pre-approval is not a final approval, and it can change or expire depending on various factors, such as your income, credit, debt, appraisal, inspection, or market conditions. Therefore, you should avoid making any major financial changes or decisions that could affect your pre-approval status, such as changing jobs, taking on new debt, or making large purchases. You should also stay in touch with your lender and update them on any changes in your situation or preferences. Finally, you should be ready to submit your final loan application and documents once you find the home of your dreams and have an accepted offer.
