Three things wreck home purchase deals between contract and closing more than anything else: changing jobs during financing, opening new lines of credit (a car loan, a furniture credit line, or a new credit card), and shopping lenders after you're already under contract instead of before you wrote the offer. Any one of these can delay your closing, cost you your earnest money deposit, or blow up the transaction entirely. The good news: all three are entirely avoidable if you know the rules going in.

What Not to Do When You Go Under Contract on a Home in Northern Virginia

Going under contract on a home in Vienna, McLean, Reston, Arlington, Alexandria, or anywhere in Northern Virginia is one of the most exciting milestones in the home buying process. It's also one of the highest-stakes stretches of your entire transaction. Between the day your contract is ratified and the day you close, there are three specific mistakes buyers make that can quietly cost them the deal, their earnest money, or both. All three are preventable. Here's exactly what to avoid, and why each one matters more than most buyers realize.

Rule 1: Do Not Change Jobs During Financing

The moment your contract is ratified, your lender restarts a full underwriting review. Your income, your employment history, your tax returns, your pay stubs, all of it gets verified again. If your employment situation changes during that review, even for a promotion or a better opportunity, your lender has to re-verify everything from scratch. That takes time. Sometimes it takes more time than your closing timeline allows.

The bigger risk: if the job change involves a shift from W-2 to 1099, a change in industry, a gap between jobs, or a pay structure change (from salary to commission, for example), you may no longer qualify for the same loan you were approved for at contract. Buyers have lost homes and forfeited earnest money in Northern Virginia because a job change made in good faith mid-transaction disqualified them from their loan program.

The rule: whatever your employment situation looked like the day your lender pulled your file, keep it looking exactly like that until closing. Ideally, until the loan officially funds. Job changes, career moves, promotions, and side businesses can all wait a few weeks. Your earnest money and your home cannot.

Rule 2: Do Not Open New Lines of Credit

This is where buyers get themselves in trouble without realizing it. Between contract and closing, you cannot buy a new car, put furniture on a store credit card, apply for a new credit card, or take out any new loan. Not for the new house, not for anything else.

Every time you open a new line of credit, your credit score changes and your debt-to-income ratio changes. Both are variables your lender used to approve your loan. If either one moves in the wrong direction between contract and closing, your loan can be delayed, restructured at a worse rate, or denied entirely.

The rule: no new credit, no exceptions. If you need to buy a car after you close, buy it after you close. If you want to furnish the new house, use cash or wait until keys are in hand. If a credit card offer arrives in the mail, throw it away. Your existing credit accounts are fine to use normally. Anything new is a risk.

Rule 3: Shop Lenders Before You Write the Offer, Not After

This is the mistake buyers make in the name of being smart. They get pre-approved with one lender to write the offer, then plan to shop rates with other lenders after they go under contract to save some money. On paper, this feels responsible. In practice, it costs days off your closing timeline and can put your entire transaction at risk.

Here's why. Once you're under contract on a Northern Virginia home, the clock is running. Standard close-of-escrow timelines are 30 to 45 days. If you switch lenders in week two, you're restarting underwriting from scratch, which typically takes 21 to 30 days. That leaves almost no buffer for anything that comes up during the process, and something always comes up. Missing your closing date can put your earnest money at risk and, in the worst case, forfeit the home.

The rule: shop rates before you write the offer. Get a fully underwritten approval (not just a pre-qualification) from your primary lender. If you want to compare rates, do it during the shopping phase with one or two other lenders simultaneously. Once you're under contract, stick with your original lender and focus on getting to the closing table on time. Our full breakdown on the Northern Virginia lender mistake that costs buyers homes walks through the deeper strategy.

What Actually Happens the Moment Your Contract Is Ratified

Understanding what your lender is doing behind the scenes makes it clearer why the three rules above matter. The moment your contract is ratified, your lender orders the appraisal, requests the title work, submits your file to underwriting, and begins verifying every piece of your financial picture in more detail than the pre-approval stage. Your bank statements are re-pulled. Your employer is called. Your credit report is often re-run just before closing to make sure nothing has changed.

This process is why the three rules are absolutes, not suggestions. Every change you make to your financial picture during this window shows up in the lender's file and creates work, delays, or full-blown problems.

How The Carey Collective Works With Your Lender to Protect Your Closing

At The Carey Collective, once a client goes under contract, we work directly with the lender, the title company, and the listing agent to keep the transaction moving without surprises. That means proactive communication with your loan officer, coordinating documentation deadlines, staying on top of the appraisal timeline, and flagging any red flag before it becomes a real problem. For relocating clients or buyers who cannot be physically present, this coordination is often the difference between a smooth closing and a stressed-out final week.

The buyer's job in this stretch is simpler than it sounds: keep your financial picture completely still. No job changes. No new credit. No lender shopping. Trust the process, respond quickly to your loan officer's requests, and let your agent quarterback the rest. Our post on how the wrong Northern Virginia agent can cost buyers $30,000 covers what the right coordination actually looks like.

A Quick Recap Before You Sign the Contract

Before you go under contract on a Northern Virginia home, commit to the three rules:

• No job changes between contract and closing
• No new lines of credit for any reason
• No lender shopping after ratification (do it before you write the offer)

If you follow those three rules and work with an agent and lender who communicate proactively, you will close on time and keep your earnest money exactly where it belongs.
