10 Things First-Time Home Buyers Do That Can Kill Their Deal (And How to Avoid Them)

Buying your first home in Omaha is one of the most significant transitions you will ever navigate.

It is a season filled with excitement, but also intense emotional weight and financial complexity.

Whether you are looking in Millard, West Omaha, or the growing neighborhoods of Papillion and La Vista, the process requires a steady hand to ensure a smooth path to the closing table.

My name is David Greiner, and before I became a REALTOR®, I spent 40 years in the funeral service industry.

That background taught me how to remain calm and focused during life’s most stressful moments.

In real estate, I bring that same sense of clarity and professionalism to your journey, serving as a “trail guide” through the peaks and valleys of the market.

I often tell my clients that the period between having an offer accepted and getting the keys is like a marathon.

The finish line is in sight, but one wrong move can trip you up.

Based on my experience helping families across Sarpy County and the Omaha metro, here are the 10 things you should absolutely NOT do during your home purchase.

Why is changing jobs during a home purchase risky?

Changing your job or quitting during a home purchase can disqualify your mortgage because lenders require a stable, verifiable income history to finalize your loan. Even a promotion with a pay raise can trigger a new round of verification that delays your closing or changes your debt-to-income ratio calculations.

When you apply for a mortgage, the lender is betting on your ability to pay back the loan based on your current financial status.

If that status changes, even for a “better” job, the underwriter has to re-evaluate everything.

If you are considering a career move, wait until after the deed is recorded and you have the keys in your hand.

Can social media posts really affect my home closing?

Yes, social media posts can affect your home closing if they reveal information about your finances, employment, or intentions that contradict your loan application or contract. Additionally, posting photos of the home before you own it can alert the seller to your emotional attachment, potentially weakening your position during inspection negotiations.

It is natural to want to share your excitement with friends and family in Bellevue or Elkhorn.

However, silence is your best friend until the transaction is legally complete.

Privacy protects your leverage and ensures that no unexpected parties: like a lender doing a final check: stumble upon information that could cause a second look at your file.

Why should I avoid talking to the sellers directly?

You should avoid talking to sellers directly to prevent accidental disclosures that could damage your negotiating power or create legal liabilities. All communication should go through your REALTOR® to ensure professional boundaries are maintained and that all agreements are properly documented in writing to protect your interests and the contract.

Real estate agents act as a necessary buffer.

Direct conversations can lead to misunderstandings or “handshake deals” that aren’t legally binding.

I’ve seen buyers accidentally mention they are “willing to pay more if needed,” which immediately hurts their position during repairs or appraisal gaps.

What should I do if a family member gives me money for a down payment?

If a family member gives you money for a down payment, you must document it as a “gift” using a formal gift letter provided by your lender. You cannot simply deposit the cash; the lender needs a paper trail showing the funds came from a legitimate source and are not a loan.

Untraceable cash is a major red flag for mortgage underwriters.

They are required by law to verify the source of all large deposits.

If you’re lucky enough to have help from family, let me and your lender know immediately so we can guide you through the proper paperwork.

Why is buying a new car or furniture a bad idea before closing?

Buying a new car or large furniture before closing is a bad idea because it increases your debt-to-income ratio and can lower your credit score. Lenders perform a final credit check just days before closing, and any new debt can disqualify you from the mortgage you were originally approved for.

I know you want that new sectional for your living room in South Omaha, or a reliable SUV for the Nebraska winters.

Wait.

Any new monthly payment: or even a large credit card charge: can tip the scales and result in a “denied” status at the eleventh hour.

How does calling the listing agent directly hurt me?

Calling the listing agent directly hurts you because that agent’s primary legal and fiduciary duty is to the seller, not you. They are hired to get the seller the highest price and best terms, whereas having your own REALTOR® ensures you have a dedicated advocate looking out for your interests.

When you see a For Sale sign in Millard, your first instinct might be to call the number on the sign.

Instead, call me.

I can get you all the same information while ensuring you have someone in your corner who is focused solely on your protection and goals.

Is taking advice from friends or family a mistake?

Taking advice from friends or family can be a mistake if they haven’t bought or sold a home recently, as real estate laws and lending requirements change constantly. While well-meaning, outdated advice can lead to unrealistic expectations or costly errors during the fast-paced negotiations common in the Omaha market.

The market in 2026 is vastly different from the market five or ten years ago.

Rules regarding earnest money, inspections, and appraisal contingencies are nuanced.

Trust the professionals who are in the trenches of the Sarpy County market every single day.

Should I wait to see every home on the market before making an offer?

Waiting to see every home on the market is often a mistake because the best properties in Omaha typically sell within days. In a competitive market, hesitation leads to missed opportunities; it is better to act decisively on a home that meets your core needs rather than waiting for a “perfect” home.

The “perfect” home is often a myth, but the “right” home is very real.

If a house in Papillion checks 85% of your boxes and fits your budget, someone else will likely buy it while you are looking for that last 15%.

Decisiveness is the hallmark of a successful first-time buyer.

Why is honesty with my REALTOR® so important?

Honesty with your REALTOR® is critical because I cannot protect you from what I don’t know. Information about child support, alimony, tax liens, or wage garnishments will eventually surface during the lender’s title and background searches, and knowing these details early allows us to address them before they kill the deal.

Think of me as your transition guide.

My 40 years in the funeral industry taught me that the truth, however difficult, is the only way to find a path forward.

I am here to help, not to judge, but I need the full picture to navigate the complexities of your sale.

What happens if I make a large cash deposit?

If you make a large cash deposit, your lender will require a detailed explanation and documentation of where the money came from to comply with anti-money laundering regulations. If the source cannot be verified, the lender may be unable to use those funds toward your closing costs or down payment.

Lenders prefer “seasoned” funds: money that has been in your account for at least 60 days.

If you sell a vehicle or receive a cash windfall, keep every receipt and bill of sale.

Without a paper trail, that money might as well not exist in the eyes of a mortgage underwriter.
