5 Mistakes First-Time Buyers Make (And How to Avoid Them)
After 15 years and 500+ first-time buyers, I have seen the same mistakes over and over. Here are the five most common — and exactly what to do instead.
After 15 years in the mortgage business and 500+ first-time buyers, I've seen a lot. And while every buyer's situation is unique, the mistakes? Those tend to repeat.
Here are the five I see most often — and what to do instead.
⚠️ Mistake #1: Shopping for Homes Before Getting Pre-Approved
This is the big one. I understand the impulse — browsing Zillow is fun, and open houses are exciting. But falling in love with a home before you know what you can afford is a recipe for heartbreak.
I've seen buyers tour $450,000 homes for months, only to discover their budget is $320,000. That's a painful recalibration.
What to do instead: Get pre-approved before you look at a single home. The process takes a few days and a bit of paperwork. Once you have your pre-approval letter, you'll know your real budget — and you can shop with confidence.
⚠️ Mistake #2: Making a Major Financial Move Before Closing
This one surprises people. You've been approved, you're under contract, you're two weeks from closing — and then you buy a new car. Or open a new credit card. Or quit your job to start a business.
Any of these can kill your loan.
Here's why: lenders verify your financial situation right before closing. If your debt-to-income ratio has changed, or your employment status has changed, or your credit score has dropped, they can — and will — pull your approval.
What to do instead: From the moment you apply for a mortgage until the day you close, treat your finances like they're frozen. No new credit. No large purchases. No job changes. No large cash deposits without documentation. Ask me before you do anything financial.
⚠️ Mistake #3: Draining Your Savings for the Down Payment
Buyers sometimes put every dollar they have into the down payment to avoid PMI or get a lower rate — and then have nothing left for closing costs, moving expenses, or the inevitable first-month repairs.
Owning a home comes with costs that renting doesn't. The water heater that dies in month two. The furnace that needs servicing. The fence that falls over in the first storm.
What to do instead: Keep a cash reserve. I generally recommend having 2–3 months of mortgage payments in savings after closing, in addition to your down payment and closing costs. If that means putting less down and paying PMI for a while, that's often the smarter move.
⚠️ Mistake #4: Skipping the Home Inspection
In competitive markets, buyers sometimes waive the home inspection to make their offer more attractive. I understand the logic — but I've seen this go very badly.
A home inspection typically costs $300–$500. It can uncover issues worth tens of thousands of dollars: foundation problems, roof damage, outdated electrical, plumbing issues, HVAC problems. These aren't things you want to discover after you've moved in.
What to do instead: Keep the inspection contingency. If the market is extremely competitive and you feel pressure to waive it, at minimum do a pre-offer inspection (some sellers allow this). Never buy a home without knowing what you're buying.
⚠️ Mistake #5: Not Understanding the True Cost of Homeownership
The mortgage payment is just the beginning. First-time buyers often focus exclusively on the monthly payment and forget about everything else that comes with owning a home.
Here's what you're actually signing up for:
- Property taxes: Varies widely by location, but often $200–$600/month
- Homeowner's insurance: Typically $100–$200/month
- HOA fees: $0 to $500+/month depending on the community
- PMI: $50–$200/month if you put less than 20% down
- Maintenance and repairs: Budget 1–2% of the home's value per year
- Utilities: Often higher than renting (you're responsible for everything now)
💸 A $1,800 mortgage payment can easily become a $2,800/month total housing cost when you add everything up.
What to do instead: Before you fall in love with a home, run the full numbers. I help my clients build a complete monthly cost picture so there are no surprises after closing.
🧵 The Common Thread
Most of these mistakes come from the same place: not knowing what you don't know. The mortgage and home buying process is complicated, and nobody teaches it in school.
That's why I'm here. My job isn't just to process your loan — it's to make sure you understand every step, avoid every pitfall, and come out the other side feeling confident about one of the biggest decisions of your life.
If you're thinking about buying — even if you're months or years away — let's talk. The earlier we connect, the better positioned you'll be when you're ready.
