How winter weather affects vacant property holding costs

Winter weather adds specific, often overlooked, expenses to holding vacant properties. You need to budget for these additional costs to accurately project your deal's profitability.

Dealing with frozen pipes and burst lines

The most common and costly winter issue for vacant properties is burst pipes. When water freezes, it expands, causing pipes to rupture and then leak once temperatures rise.

Prevent this by draining the water system completely or by keeping the heat on at a minimum temperature, usually around 10-13 degrees Celsius (50-55 degrees Fahrenheit). This is often called winterizing the plumbing.

Even with precautions, you should regularly check on the property or hire someone to do so. Early detection of a burst pipe can significantly reduce water damage and repair costs.

Preventing mould and water damage

Beyond burst pipes, cold and damp conditions can lead to mould and mildew growth, especially in unheated or poorly ventilated properties. This can quickly escalate into a major remediation expense.

Ensure adequate ventilation, even in winter, to reduce humidity. You might also consider using dehumidifiers if the property cannot be fully drained or heated.

Regular inspections help you spot early signs of moisture intrusion, mould, or mildew. Addressing these issues promptly prevents them from spreading and becoming more expensive to fix.

Heating and utility considerations

Keeping the heat on to prevent freezing incurs utility costs, which can be substantial during colder months. Factor in higher energy bills for the duration of your holding period.

Even if you winterize the plumbing, you may still have electricity costs for security systems or minimal lighting. Some investors keep the main breaker on for certain appliances or to prevent electrical issues.

Compare the cost of full winterization (draining systems, adding antifreeze to traps) against the cost of maintaining minimal heat. The best approach depends on the local climate severity and the anticipated holding time.

Maintaining exterior and grounds

Winter weather can also affect the exterior of a vacant property. Snow and ice accumulation on roofs can lead to ice dams, causing water to back up and damage eaves or interior walls.

Clearing snow from driveways and walkways is often necessary for access and to avoid local code violations or potential liability if someone slips. This might require hiring a service.

Gutters and downspouts should be clear of debris before winter to ensure proper drainage and prevent ice build-up. Neglecting exterior maintenance can lead to more significant structural issues by spring.

Increased security and monitoring during winter

Vacant properties can attract more attention from vandals or squatters during the colder, darker winter months. Reduced neighborhood activity can make them easier targets.

Consider enhanced security measures, such as boarding up windows, reinforcing doors, or installing motion-activated lighting or cameras. These add to your holding costs.

Frequent checks on the property are even more critical in winter to ensure it remains secure and that no new damage has occurred. A well-maintained exterior can also deter unwanted attention.

Questions people ask

Does winter affect insurance rates for vacant properties?

Yes, many insurers view vacant properties as higher risk, especially in winter. Some policies may have specific clauses or require additional coverage for vacant homes during colder months, potentially increasing your premiums.

How early should I winterize a property?

Winterize your property before the first hard freeze is predicted for your area. It's better to do it a bit early than to wait too long and risk burst pipes from an unexpected cold snap.

What's the biggest winter cost I might miss?

Many investors underestimate the cost of continuous heating, even at a low setting, or the expense of unexpected emergency repairs from burst pipes or ice dam damage. Always budget a contingency for these.
