Buying a house is a big decision, and it comes with a lot of unknowns. Even if the home looks great on the surface, there could be hidden issues that cost you later. That’s why it’s smart to ask the right questions—especially before, during, and after the home inspection.
We’re sharing important questions to ask when buying a house, plus helpful tips to keep them organized.
What to Know Before You Start Asking
Before jumping in, it’s good to know who to ask and when. Your real estate agent, the seller, and your home inspector can each offer different insights.
Some questions are best asked during a showing. Others make more sense after the inspection report is in your hands. Bring a notebook or use your phone to take notes—you won’t remember everything, especially if you’re touring multiple homes.
Also, keep in mind that whether you’re a first-time buyer or not, there are no bad questions. If something feels off or confusing, ask about it.
15 Smart Questions to Ask When Buying a House
The questions are grouped to help you cover all the bases, from the home’s history to future costs and safety concerns.
About Property History and Condition
1) Has the home had any past repairs or major issues
Ask about foundation work, water damage, termite problems, or storm-related repairs. Sellers are required to disclose many issues, but it’s worth asking directly.
2) How old are the roof, HVAC, and other key systems?
Roofs usually last 15–30 years. HVAC systems and water heaters tend to last around 10–15 years. If these are nearing the end of their lifespan, plan for replacements.
3) Have there ever been signs of water damage or mold?
Even past leaks can leave hidden damage. Look for water stains on ceilings or musty smells in closets and basements.
Inspection Findings or Impressions
4) Are there any cracks or structural concerns I should know about?
Hairline cracks are common, but larger ones can point to movement or foundation trouble.
5) Is there evidence of past pest activity or damage?
Termites and rodents can cause damage behind walls and under floors. If there’s been activity, ask if it was treated and repaired professionally.
6) Should I be concerned about radon, lead, or asbestos?
In older homes especially, these can be real concerns. A qualified inspector will recommend additional testing if needed.
7) Is the electrical panel up to code?
Old panels may not support modern appliances or may pose safety risks. Ask if it’s been upgraded or if there’s room for expansion.
8) Are there signs of DIY work that could cause problems later?
Unpermitted additions, amateur wiring, or odd plumbing fixes can create future headaches.
Future Costs and Maintenance
9) What upcoming repairs should I budget for?
Even if a home passes inspection, normal wear and tear means you may need to plan for updates like new siding, driveway sealing, or appliance upgrades.
10) How energy-efficient is the home right now?
Ask about insulation, windows, and HVAC efficiency. Poor insulation can lead to higher utility bills.
11) Is the grading around the home protecting the foundation?
Water should flow away from the home. If the yard slopes toward the house, it could lead to moisture issues or even foundation damage over time.
About the Surroundings and Safety
12) Are there drainage or septic issues to be aware of?
Ask about slow drains, past backups, or strong odors—these can be signs of septic system trouble or clogged lines.
13) Has the neighborhood had foundation or soil movement problems?
Some areas are known for shifting soil or expansive clay, which can cause structural issues. Your inspector will usually note if the area is at higher risk.
Bonus Questions
14) What’s the typical lifespan of the materials used in this home?
From flooring to siding, different materials wear down at different rates. Knowing what’s been used helps you plan for future upkeep.
15) Would you buy this home if you were in my shoes?
This is a great question to ask your home inspector at the end of the inspection. A good inspector won’t tell you what to do, but they can give helpful context based on their experience.
Other Maintenance to Think About
Getting answers to the right questions is a great first step to buying your house confidently. But owning a home also means staying ahead of issues and expensive repairs.
Once you settle in, small maintenance habits can go a long way in protecting what’s likely your biggest investment. Start with these:
- Clean gutters and downspouts every season to keep rainwater flowing away from the foundation. Clogs can lead to water pooling near the base of the home, which increases the risk of cracks or shifting.
- Have your HVAC system serviced twice a year, ideally in the spring and fall. This helps avoid breakdowns when you need heating or cooling the most—and extends the system’s life.
- Check the attic and crawl space for signs of moisture like musty smells, damp insulation, or visible mold. Poor ventilation can trap humidity and lead to wood rot or hidden damage.
- Touch up exterior caulking and paint every couple of years to seal out pests and weather. This simple task helps preserve siding, trim, and energy efficiency.
- Walk the perimeter of your home regularly—look for cracks in the foundation, loose soil, or anything unusual near the base of the house or driveway.
When to Call a Professional
You don’t have to have all the answers. And you definitely shouldn’t try to spot every issue on your own. Bring in a professional for an independent home inspection.
