Charming older homes are easy to fall in love with. Original hardwood floors, cozy fireplaces and unique nooks might make your home-buyer heart go pitter-patter. But before you get carried away imagining your picturesque life in an older home with vintage character, it's important to consider what's hiding behind the walls. Asking the right electrical questions during your home inspection process can help you avoid safety issues and shockingly expensive surprises down the line.

Here are nine questions to start with during the electrical inspection of your potential home.

1. Is the Electrical Up to Code?

Knowing that a new-to-you home has an electrical system that's safe and up to code offers a lot of peace of mind. You won't have to worry about electrical safety as you move in and start plugging in your electronics, and work that's been given the nod of approval by a licensed electrician is less likely to create problems for you in the future.

2. When Was the Electrical System Last Updated?

An older home or electrical system is less likely to meet the current electrical code. For example, older electrical panels and wiring may not incorporate safety standards that newer construction is required to use.

3. Are There Known Issues With the Electrical System?

Consider asking the seller if there are known electrical issues before buying a home. For example, ask if they've noticed issues like flickering lights or if they're regularly having to reset the circuit breakers. Your home inspection professional will also keep an eye out for obvious issues. When you're informed about such issues, you might be able to work them into pricing negotiations.

4. What Work Has Been Done, and Who Did It?

Whether or not known electrical problems exist now, work may have been done in the past on the home's electrical system. Ask for details and documentation of work, including rewiring, the addition of outlets and updates to electrical panels. Ideally, you want to see that a licensed electrician handled the work. If the homeowner did any of the work themselves, ask questions about their qualifications, exactly what type of wiring and other materials they used and where the work was done. Ensure your inspector can set eyes on the DIY work to ensure it's safe and up to code.

5. What Type of Wiring Is in the Home?

Older wiring materials can increase the risks of fire hazards in homes. Ensure you know what type of wire is running through the home and whether you may need to pay to replace it in the near future. For example, knob-and-tube wiring was common in the early 1900s, but it's a fire risk and should be replaced as soon as possible.

6. Are There Any Two-Prong or Ungrounded Outlets in the Home?

Find out whether there are ungrounded outlets in the home. Older-style outlets can increase fire hazards, and you won't be able to plug in items that have a three-prong plug without an adapter.

7. Are GFCI Outlets Installed in Appropriate Locations?

Ground fault circuit interrupter, or GFCI, outlets are generally required in areas where water might pool nearby. That includes in areas near kitchen sinks and in bathrooms. This is a safety and code requirement, and if you buy a home with noncompliant outlets in these spaces, you may need to upgrade them.

8. Does the Home Have Any Energy-Efficient Electrical Features?

While you're discussing electrical considerations with the seller, you might want to ask about energy-efficient features. Smart home devices, LED lighting and other upgrades can be helpful for your energy bill and might help defray other costs associated with your new home purchase.

9. Do Dedicated Circuits Exist Where Appropriate?

Ask about dedicated circuits for major appliances. HVAC systems, washer and dryer units and even microwaves draw a lot of energy. When circuits aren't designed or dedicated appropriately, you might find yourself taking frequent trips to the electrical panel to flip breaker switches.
