Great question--I see this confusion literally every week in our deals at Greenlight Offer. Pre-approval is basically the lender saying "we *think* you can borrow this much based on what you told us," but it's not a guaranteed loan. The actual mortgage doesn't exist until you clear underwriting, which happens *after* your offer is accepted. Here's what actually happens: Once you're under contract, the lender orders the appraisal, verifies your income/assets again, pulls credit one more time, and underwrites the entire file. I've watched deals fall apart 5 days before closing because the buyer changed jobs or financed a car--things that weren't issues during pre-approval suddenly killed the loan. The timeline from accepted offer to closing is typically 30-45 days, and buyers need to keep their financial situation frozen during that period. My advice? Get your pre-approval letter, but understand it's just your ticket to play--not a guaranteed seat at the table. Don't make any major purchases, don't change jobs, and stay in constant contact with your lender during the process. We close 15-20 deals monthly, and the buyers who sail through are the ones who treat that pre-approval period like they're walking on financial eggshells until the keys are in their hand. The real nightmare scenario is when buyers drain their accounts for repairs or moving expenses before closing, then can't show the required reserves at final underwriting. Keep enough cash accessible and documented until you're completely done.

A pre-approval for a mortgage and a final approval for a mortgage are two very different things. A pre-approval means that a loan officer has looked over your application, done a quick run of your credit score, talked to you about your debts and assets, and, based on all of that, thinks you could get a mortgage. The loan officer may have also had you send in some bank statements and check stubs to verify the income and assets. Actually getting the mortgage is a little more complicated. The loan application needs to go through full underwriting to make sure that your income, assets, and debts are accurate. The underwriter will verify your employment and make sure that the money in your bank accounts is "seasoned." This means it's been in the account for a certain period of time and not just deposited. If it was just deposited, they will want to know where it came from - a paycheck, a gift, etc. The underwriter will also make sure that the property you are buying is valued at the price you are purchasing it for and that it is livable. By the end of the mortgage process, it can sometimes seem like you are a circus performer because of all the hoops you've jumped through. The process is complicated to make sure you aren't in over your head and to protect you and the lender from fraud. Having a good loan officer and real estate agent will help make the process go more smoothly and be less stressful.
Pre-approval only says a lender is *willing* to lend if nothing in your file or in the property breaks the logic. It is not money. After the offer is accepted you still go through full underwriting — income re-checks, asset verification, appraisal, title work, insurance, and sometimes credit pulled again. Any one of those can stall or kill a file. Think of pre-approval like a supplier's soft quote at SourcingXpro — it signals intent, not execution. The advice is simple: don't change jobs, don't open debt, don't move cash around, and respond to lender requests same-day. Speed and stability win mortgages more than hope.
