Evaluating Resale Homes: Mechanical Red Flags and Choosing the Right Property

When touring resale houses or newly remodeled "flipped" homes, it is easy to get distracted by visual enhancements like open layouts, modern countertops, and fresh paint. However, the most expensive components of a home are hidden behind the walls or located in the mechanical room.

Replacing a failing furnace, rewriting aluminum wiring, or repairing a cracked foundation can easily cost tens of thousands of dollars. To protect your purchase capital, you should know how to identify these mechanical red flags during your very first walk-through.

What heating systems and energy sources are common in Canada?

Canadian homes rely on three main heating structures:

• Forced Air Heating: The most modern and standard system. It uses a furnace to blow heated air through ductwork. The primary advantage is that the same ductwork supports central air conditioning and air filtration systems.
• Hot Water Heating (Radiators): Uses a boiler to pump heated water through cast-iron or baseboard radiators. While very quiet and clean, this system cannot support central air conditioning without installing separate ductless mini-split units.
• Electric Baseboard Heaters: Simple and cheap to install, but extremely expensive to operate during cold Canadian winters. Freehold homes with purely electric baseboard heat often sell at a discount due to high utility costs.

What should you look for in the electrical system?

Open the main electrical panel during a showing. First, check the **Service Amperage**—modern homes require at least **100 amps** to run appliances, while homes with **200-amp service** are ideal for future additions like electric vehicle chargers.

Be on high alert for homes built in the late 1960s to late 1970s, which may contain **Aluminum Wiring**. Aluminum wiring can oxidize at connection points, creating a serious fire hazard. Many insurance providers will refuse coverage unless a certified electrician inspects and pig-tails the entire system with copper connectors.

How do you separate curable defects from incurable defects?

When deciding on a property, apply the **Principle of Progression**: buy one of the cheaper homes in a premium neighborhood. This ensures the surrounding homes pull your property value up. Focus on curable cosmetic defects—such as outdated bathrooms or peeling paint—which you can fix over time. Avoid homes with incurable defects, such as backing onto a busy railway line or high-voltage power lines, as these issues cannot be changed and will permanently drag down appreciation.
