What Buyers Should Look for in Older Homes

Older homes often have charm, history, and solid craftsmanship that newer builds can’t replicate. But they also come with unique considerations buyers should carefully evaluate. Whether you’re drawn to the character of a 1950s bungalow, a mid-century gem, or a classic colonial, here’s what buyers should look for before making an offer.

1. Structural Condition and Foundation Health

The foundation is the backbone of the home — and many older properties show signs of settling or age-related shifts.

Look for:

• Cracks in walls or ceilings

• Sloping or uneven floors

• Sticking doors and windows

• Gaps between walls and trim

A structural engineer or specialized inspector can provide deeper insight.

2. Roof Age and Material Quality

Roofs on older homes may be near the end of their lifespan.This can impact both safety and insurance rates.

Check for:

• Age of the roof

• Missing shingles

• Sagging areas

• Water stains inside the home

A roof replacement can be costly, so factor this into your budget.

3. Electrical System and Wiring Safety

Older homes may have outdated or unsafe wiring such as:

• Knob-and-tube wiring

• Aluminum wiring

• Undersized electrical panels

These systems may not support modern appliances or charging needs and might require upgrades.

4. Plumbing Type and Water Pressure

Old plumbing can include galvanized pipes, which corrode and reduce water flow.

Things to review:

• Pipe material (copper and PEX are best)

• Water pressure in all fixtures

• Condition of drains

• Hot water heater age

Replacing plumbing in an older home can be a major project.

5. Windows and Insulation Efficiency

Many older homes have original windows — beautiful, but not always energy efficient.

Check:

• Drafts around windows

• Single-pane vs. double-pane glass

• Condition of seals

• Wall and attic insulation

Better insulation reduces energy costs and makes the home more comfortable.

6. The Condition of Floors and Subflooring

Original hardwood floors add value and character, but the subfloor may reveal underlying issues.

Watch for:

• Soft spots

• Creaking

• Water damage

• Uneven flooring

These signs can indicate structural or moisture problems.

7. HVAC System Age and Functionality

Older homes sometimes rely on outdated heating or cooling systems that are inefficient or unreliable.

Check:

• Furnace and AC age

• Ductwork condition

• Whether the home has proper ventilation

• Signs of inconsistent heating or cooling

Modern systems greatly improve comfort and energy efficiency.

8. Evidence of Moisture or Water Damage

Older homes may have moisture issues due to outdated waterproofing or drainage systems.

Look closely for:

• Mold or mildew smells

• Water stains

• Damp basements or crawl spaces

• Poor grading around the home

Moisture issues should always be addressed promptly.

9. The Integrity of Original Features

Original details like:

• Solid wood doors

• Decorative trim

• Crown molding

• Built-in cabinetry

• Plaster walls

…can add tremendous value.Check their condition and consider what can be restored vs. replaced.

10. Renovation History and Permit Records

Many older homes have been updated over the years — some professionally, some DIY.

Be sure to verify:

• Which work was done with permits

• Whether additions meet current code

• The quality of prior renovations

• Any unpermitted structures

Proper documentation protects you in the long run.

Final Thoughts

Older homes offer character, charm, and craftsmanship you won’t find in most new builds — but they require a careful, informed evaluation. By paying attention to structure, electrical systems, plumbing, insulation, and renovation history, buyers can confidently invest in an older home that blends personality with practicality.
