by Sara M. Buying your first home is a massive deal congrats if you're doing it this year! It’s exciting and maybe a little terrifying. You’ve probably been daydreaming about furniture, paint colors, and having your own space to throw the kind of dinner parties where nobody has to balance a plate on their lap. But here’s the thing most people won’t tell you: owning a home comes with a whole new level of responsibility, especially when it comes to cleaning and maintenance. And first-time homebuyers? We tend to make some classic (and totally avoidable) mistakes. That’s where I come in. I’m here to spill the tea on what to look out for in 2025 so you can save time, money, and a whole lot of stress. So, grab a coffee, take a seat, and let’s talk about the biggest homeownership mistakes you don’t want to make this year. 1. Thinking You’re Done After Moving In Okay, so you've signed the papers, you’ve got the keys, and all your boxes are in. You’re home! Now, it’s Netflix and chill forever, right? Not quite. A lot of new homeowners fall into this trap of thinking the hard part is over. The truth is, moving in is just the beginning. There are filters to change, vents to clean, caulking to replace, gutters to check… you get the idea. If you ignore that stuff, it doesn’t go away. It just builds up until something breaks, and suddenly your weekend plans involve fixing a leaky faucet instead of brunch. Tip: Make a “maintenance calendar” for the year. Seriously. Even a Google Doc will do. List stuff like cleaning gutters, replacing air filters, checking for leaks, and calling in professionals like a duct cleaner service once a year. You'll thank yourself later . 2. Underestimating the Power of Deep Cleaning You know that weird smell in the fridge? Or the dust you find behind the dryer? Yeah, deep cleaning isn’t just for spring. When you move into a new place especially if it was previously lived in deep cleaning everything is non-negotiable. Even if it looks clean, it might not be clean. We’re talking: • Cabinet interiors • The tops of ceiling fans • Under appliances • Inside light fixtures • Vents and air ducts There’s a good chance previous owners didn’t clean every nook and cranny before handing over the keys. And that grime? It’s now your grime. Gross, I know. Tip: Before you move your stuff in, block off one day to deep clean every single inch. Or hire someone if you can swing it. It’s worth it . 3. Ignoring HVAC Systems Until They Break Your HVAC (Heating, Ventilation, and Air Conditioning) system is like your home’s lungs. And just like lungs, it needs clean air to work properly. One big mistake new homeowners make is forgetting to schedule regular maintenance for this system. It’s super easy to forget, especially if everything seems fine. But then comes the first cold night or blazing summer day when the system sputters out and you're stuck shivering or sweating and waiting for an emergency repair that costs twice as much. Tip: Schedule an annual HVAC inspection and cleaning. And yes, this includes replacing filters and cleaning your air ducts. If it’s been a few years since the last service, it might be time to call a duct cleaner service to get everything back in shape. 4. Overlooking Water Damage (Until It’s Too Late) Water is sneaky. One tiny leak behind a wall can turn into a mold nightmare before you even know something’s wrong. And the worst part? Many first-time buyers don’t notice the signs until it’s already caused damage. Things to watch out for: • Brown or yellow stains on the ceiling or walls • Soft spots on floors or drywall • A musty smell that won’t go away • Higher-than-usual water bills Even a minor leak can turn into an expensive repair if you let it fester. Tip: Make it a habit to check under sinks, around toilets, and near your water heater every few months. Look for puddles, drips, or mold. Don’t ignore the signs. 5. Skipping Gutter Cleaning This one’s not glamorous, but it’s a biggie. Clogged gutters can lead to water backing up onto your roof, leaking into your home, or ruining your landscaping. And no, your roof isn't made to act like a giant birdbath. It’s easy to forget about gutters, especially if you live in a place that doesn’t see tons of rain. But even light rain can cause damage if it doesn’t drain properly. Tip: Clean your gutters at least twice a year. Spring and fall are ideal. Or hire someone to do it for you. It’s not expensive, and it can save you thousands in water damage repairs . 6. Failing to Budget for Maintenance You’ve probably budgeted for your mortgage, utilities, and maybe even that new couch. But have you set aside a maintenance fund? Because let me tell you stuff will break. Things wear out. And nothing's worse than needing a new hot water heater and realizing your bank account just said, “lol, good luck.” A general rule of thumb is to set aside 1%–2% of your home’s purchase price each year for maintenance. So if your home costs $300,000, you’re looking at saving $3,000 to $6,000 annually. Tip: Open a separate “home emergency fund” in your bank. Out of sight, out of mind and there when you need it . 7. Forgetting the Importance of a Clean Basement If your new place has a basement, don’t treat it like the dark hole where Christmas decorations go to die. Basements are prone to dampness, mold, and critters if not maintained properly. Check it often for: • Moisture or leaks • Cracks in the foundatio n • Mold on walls or ceilings • Weird smells Even if you don’t plan on finishing your basement anytime soon, keeping it clean and dry can protect the rest of your home. Tip: Run a dehumidifier in the warmer months. And once a year, give it a full clean sweep, mop, and declutter. You never know when you’ll need that space . 8. Assuming Appliances Will Last Forever We get it you’ve just dropped a ton of money on your new house. The last thing you want to do is replace the fridge. But if it’s older than your Netflix account, you might not have a choice. Old appliances aren’t just inefficient, they can be ticking time bombs. Fridges leak, dishwashers flood kitchens, and dryers catch fire. No, seriously. Tip: Ask your home inspector for estimates on how old your appliances are. Then, budget to replace them before they die. In the meantime, clean behind them (like, move them out!) and give them regular maintenance. You’ll add years to their life. 9. Not Changing the Air Filters This one’s easy, and yet so many first-time homeowners forget about it. Your HVAC filters need to be changed every 1–3 months depending on your system, pets, and lifestyle. Dirty filters don’t just mess with your air quality, they can cause your system to work overtime and eventually break down. Tip: Buy a 6-pack of filters and set a calendar reminder. Change them on the first of every month if you’ve got pets or allergies. It’s quick, cheap, and makes a big difference. 10. Leaving Exterior Cleaning for “Later” It’s tempting to focus all your energy on decorating the inside, but don’t forget the outside of your home needs love too. Dirty siding, clogged exterior vents, mossy roofs, and spider web-covered porch lights can all add up to big problems later. Plus, keeping the exterior clean protects your investment and keeps your curb appeal on point. Tip: Schedule a pressure washing once a year, clean your windows seasonally, and don’t let that leaf pile sit against the house all winter. Exterior cleaning is part of maintenance, not just aesthetics . 11. Not Knowing Where Your Shut-Off Valves Are Imagine you walk into your kitchen and water is gushing from under the sink. You panic. You scream. You grab towels. But do you know where the main water shut-off is? A surprising number of first-time buyers don’t. And those minutes of scrambling can make a huge difference in water damage. Tip: As soon as you move in, find the shut-off valves: main water, gas, and circuit breaker. Label them. Make sure your partner or roommates know where they are too. Emergencies are way less scary when you’re prepared. 12. Letting Clutter Take Over Storage Spaces When you first move in, you might think, “Wow, so much space!” But that illusion fades fast once every closet and cabinet is full of random junk you didn’t even realize you owned. Clutter builds up quickly, and once it starts, it’s hard to get under control. Messy garages, overstuffed attics, and chaotic closets make cleaning and maintenance harder. Tip: Once a season, do a quick purge. Donate or toss what you don’t need. Organized storage = easier life. 13. Overlooking Seasonal Maintenance Every season brings new to-dos for homeowners. Spring means cleaning and landscaping. Summer brings lawn care and outdoor maintenance. Fall is all about prep for winter. And winter? It’s a good time to check for drafts and frozen pipes. It sounds like a lot, but breaking it down by season helps keep it manageable. Tip: Keep a seasonal checklist on your fridge or phone. A little effort now saves you from big issues later . 14. Thinking You Can DIY Everything YouTube is great. But sometimes, it lies. Or at least, it makes things look way easier than they are. One of the biggest mistakes new homeowners make is thinking they can fix anything themselves. Now, I’m all for learning new skills. But when it comes to electrical work, plumbing, or anything structural, call a pro. You’ll save money in the long run by avoiding expensive mistakes. Tip: Build a list of trusted local contractors, handy people, and cleaners (including a duct cleaner service you trust). Don’t wait until something’s broken to go searching. 15. Treating Your Home Like a Rental This one’s a mindset shift. You’re the owner now. That creaky floorboard? You fix it. That dingy carpet? You replace it. It’s not someone else’s job anymore. A lot of new homeowners keep that renter mentality for too long, waiting for someone else to handle things or not wanting to spend money on fixes. But your home’s value depends on regular upkeep and so does your comfort. Tip: Treat your home with love and care, and it’ll return the favor. Final Thoughts (Not a Conclusion, Promise) Owning a home is one of the most rewarding things you’ll ever do. But it’s also a big responsibility and the learning curve can be steep. The key? Stay curious, stay proactive, and don’t be afraid to ask for help when you need it.
