I've seen good loans fall apart two days before closing because someone bought a truck. A $45,000 auto loan, signed the week before closing, torpedoed a debt-to-income ratio that had been perfectly structured for six months. The buyers lost the home. The seller was furious. Everyone's time was wasted. These disasters are preventable, but only if you know to look out for them.
Mistake 1: Changing Jobs During the Loan Process
Lenders verify employment at application and again right before closing. If you change jobs between pre-approval and closing, even for more money, it can require a full re-underwrite and delay or derail the loan. Going from W-2 to self-employed is especially damaging. If you're considering a job change during your transaction, tell me first. We'll figure out the timing together.
Mistake 2: Opening New Credit After Pre-Approval
Every new credit account or hard inquiry can lower your score and increase your reported debt obligations. Opening a credit card, financing furniture, or signing up for a store card during the loan process can change the numbers the underwriter approved. Don't open anything new until after you close, not even the home improvement card at the hardware store.
Mistake 3: Making Large Purchases, Especially a Car
This is the truck story. A new car payment can push your debt-to-income ratio over the qualifying threshold. On a $380,000 loan, even a $400/month car payment can be the difference between approval and denial. No major purchases until the keys are in your hand.
Mistake 4: Moving Money Without Documentation
Underwriters must source every large deposit in your bank accounts. If you move $20,000 from savings to checking, transfer from a parent, or sell something for cash, every dollar needs a documented paper trail. Undocumented deposits get flagged and can delay or block closing. Don't move money without telling me first so we can document it properly from the start.
Mistake 5: Making Offers Without Pre-Approval
Pre-approval isn't a formality in this market, it's a prerequisite for competitive offers. Sellers and their agents will not seriously consider an offer from an unverified buyer. A verbal quote from an online calculator is not pre-approval. Full pre-approval means your income, assets, credit, and employment have been verified.
Mistake 6: Confusing Pre-Qualification With Pre-Approval
Pre-qual is usually just a conversation, no documents reviewed, no credit pulled, no underwriter involved. Pre-approval means verified documents and a credit check. They are not the same thing. In a competitive market like Bakersfield, submitting an offer with a pre-qual letter instead of a pre-approval letter tells the seller you haven't actually been vetted.
Mistake 7: Draining Your Savings for the [Down Payment](/calculators/down-payment)
Lenders want to see reserves after closing, typically two to six months of mortgage payments left in the bank. Buyers who zero out their accounts for the down payment can get denied even after getting pre-approved. Plan your down payment so you still have reserves left over. If you're short on both, DPA programs can help preserve your cash cushion.
Mistake 8: Ignoring APR and Lender Fees
A low rate with high fees can cost more over five years than a slightly higher rate with minimal fees. Always look at the Loan Estimate, every lender must provide one within three business days of application. Compare the total fees, not just the headline rate. Section A of the Loan Estimate shows origination charges and discount points clearly.
Mistake 9: Skipping the Rate Lock
Rates move daily. Once you have an accepted offer, lock your rate. Floating past an accepted offer and hoping rates improve is speculation, and it often goes the wrong way. Most standard 30 to 45-day locks are free. Extensions cost money, so make sure your closing timeline is realistic when you lock.
Mistake 10: Not Comparing Multiple Lenders
Accepting the first quote you receive is leaving money on the table. Studies consistently show borrowers who get multiple competing quotes save significantly over the life of the loan. Shopping within a 45-day window counts as one credit inquiry. Use that window, compare at least two or three quotes with Loan Estimates.
Mistake 11: Not Reading the Loan Estimate and Closing Disclosure
These two documents tell you everything about your loan, rate, fees, monthly payment, what's in escrow, and what you owe at closing. Buyers who don't read them often show up at the closing table surprised by numbers that were disclosed weeks earlier. Read both documents line by line. Call your loan officer about anything you don't understand.
Mistake 12: Taking Advice from People Who Bought 15 Years Ago
The mortgage market in 2010 was completely different from today. Guidelines, programs, and rates have all changed substantially. Your brother-in-law who put 5% down in 2012 in a different state is not a reliable source for current program specifics. Get your information from someone who is active in this market every single day.
Bottom Line
Most mortgage disasters are entirely preventable. The buyers who get into trouble are almost always ones who made a financial move during the loan process without telling their loan officer first. The rule is simple: before you buy anything, move money, change jobs, or open new credit, call me. A two-minute conversation can save a transaction that took months to build.
