When you apply for a mortgage on a home in Mountain View, the approval you receive is not permanent. Lenders continue to verify your income, assets, and credit right up until closing day. Understanding the do’s and don’ts of this window is the difference between getting the keys and losing the deal entirely.

You know how it feels when you finally find the right home, you submit your application, and you think the hard part is over? And then someone tells you that the next few weeks are actually where most deals quietly fall apart? A lot of buyers in Mountain View have been in exactly that position. But here is the part most people have not stopped to think about yet: the decisions you make between application and closing can unwind everything you worked for.

Have you ever stopped to consider how many financial moves feel completely harmless on the surface but look alarming to a lender? That is worth sitting with for a moment.

What Does Your Financial Picture Look Like Right Now?

Before we get into the do’s and don’ts, take a quick mental inventory. Are you renting month to month and watching that rent creep up each year? Are you pre-approved and actively shopping Mountain View homes for sale? Or are you somewhere in between, approved but not yet closed?

Whatever your situation, the question worth asking is this: do you actually know which everyday financial actions could put your loan in jeopardy? Most buyers do not, until they find out the hard way.

The Do’s and Don’ts Most Buyers Learn Too Late

Here is where the do’s and don’ts get specific. These are not obscure technicalities. They are the exact situations loan officers flag every single week.

Do not deposit cash into your bank accounts before talking to your lender. Lenders are required to trace every dollar in your accounts. Cash is hard to document. Even a generous gift from a family member can raise questions if it is not handled correctly. The don’ts here are simple: no cash deposits without a conversation first.

Can you see how something as innocent as depositing birthday money could create a paperwork headache that slows your closing?

Do not make any large purchases before you close. No new furniture. No new car. No appliances on a store credit card. Every new monthly obligation changes your debt-to-income ratio. A ratio that looked healthy the day you applied might no longer qualify you after a single large purchase. That ratio matters more than most buyers realize when their home loan is being underwritten.

Do not co-sign any loans for anyone. Even if you have zero intention of making the payments, your lender counts that obligation against you. The numbers change, and sometimes the approval changes with them.

Do not switch bank accounts. Lenders need to track your assets across a consistent paper trail. Moving money between accounts, even with good reason, can create gaps that require additional documentation and delay your closing.

The Do’s and Don’ts Around Credit Are Especially Costly

Your credit score on closing day needs to match or exceed the score that earned your approval. Two specific moves can quietly damage that score in ways that surprise buyers.

Do not apply for any new credit. A new credit card, a car loan, a store financing offer, all of these trigger hard inquiries across financial channels. Multiple hard inquiries lower your FICO score. A lower score changes your interest rate. In some cases, it changes your eligibility entirely. The do’s and don’ts around credit are not suggestions; they are guardrails with real financial consequences.

Do not close any existing credit accounts. This one surprises people. Many buyers think less available credit signals responsibility. It does not. A meaningful part of your credit score is built on your total available credit and the length of your credit history. Closing accounts shortens that history and reduces your available credit, both of which hurt your score.

Does that make sense? The math works against you even when your instinct says you are being responsible.

What Happens If You Ignore These Guidelines?

Here is the consequence question worth sitting with. What happens if you make one of these moves and your loan falls through two weeks before closing? You may lose your earnest money deposit. You may lose the home. And in a market like Mountain View real estate, where inventory is limited and competition is real, you may not easily find another property at the same price point.

What would that cost you, not just financially, but in time, energy, and opportunity?

Average home values in Mountain View have remained elevated relative to the broader Bay Area, which means the stakes on every transaction are higher here than in most markets. Buyers who protect their approval protect a significant financial asset.

One Overlooked Do: Keep Your Lender Informed

Here is something the don’ts list rarely mentions. If something in your financial life changes, a job shift, an unexpected expense, a change in employment status, the smartest move is to tell your lender before they discover it on their own. Lenders re-verify employment and income before funding. Surprises at that stage are far more damaging than a proactive conversation weeks earlier.

If you are actively buying in Mountain View, your loan officer is your most important partner between application and closing. Not your broker. Not your family. Your loan officer.

Based on what buyers consistently report, the deals that fall apart in the final stretch almost always involve a financial decision the buyer thought was too small to mention. It rarely is.

Are You Ready to Have a Straightforward Conversation?

Do you get the sense that navigating this process on your own, without clear guidance, could be costing you more than you realize? If so, the next step is simple. Not a sales call. Not a pitch. Just a direct conversation about where you are and what the path to closing actually looks like for your specific situation.
