Purchasing an Older Home? Watch Out for These Expensive Repairs

If you’re among the many who have a deep appreciation for old houses, you’re not alone. After 17 years working on This Old House, I’ve encountered countless individuals who share this passion. Now, as I help people buy and sell homes in an area where houses average almost 60 years old, I meet plenty of buyers—perhaps like you—eager to invest in a home with character. For those of us who cherish older homes, we understand that we’re stewards of a property with a rich history, and if we take care of it, it will last long after we’re gone.

While newly built homes might be easy to move into, old-house lovers seek something more—soul and charm that comes with age. But buying an old house requires more than just admiring its character; it requires attention to potential issues. Here’s what to keep in mind during your search.

Start with Patience
Don’t worry too much. Most old homes are still standing because they were built well, with quality craftsmanship and durable materials. Your goal is to avoid buying one of the few poorly constructed homes that didn’t last. Be sure to work with an agent familiar with historical homes, hire an experienced home inspector, and consult a contractor. But also trust your instincts.

What to Look Out For

Foundation Issues
Pay attention as you approach the house. Check the roofline and exterior walls for any signs of sloping or tilting. If you notice anything off, take note, but remember, many old houses have shifted slightly over time. What matters is the severity—look for significant leaning, uneven floors, or structural damage. Water infiltration can also cause serious foundation problems, especially in homes with stone foundations.

Moisture Problems
Water damage can destroy a home. Inspect gutters, downspouts, and roof areas, and watch for peeling paint or stains on walls that might indicate leaks. Check the basement for moisture and any musty odors caused by mold or mildew. Excess moisture can lead to bigger problems, so ask your inspector about solutions like sump pumps, French drains, or dehumidifiers.

Necessary Upgrades
Older homes often require significant upgrades like new wiring, plumbing, or insulation. Keep in mind that these updates will be out-of-pocket costs, as they typically aren’t reflected in the home’s asking price. When considering costly projects, think twice about reconfiguring stairs, finishing basements, or replacing original windows. Restoring old windows and improving insulation is often a better investment than replacing them entirely.

The beauty of buying an old house lies in the joy of stewardship. With the right knowledge and expert guidance, you can enjoy the charm and character of an older home while ensuring it stands the test of time. Keep your eyes open for potential issues and plan for the necessary repairs, and you’ll find yourself enjoying a timeless space for years to come.
