House vs. Duplex Construction Cost Quiz

What is typically cheaper upfront, a single-family house or a duplex?

A single-family house is typically cheaper upfront due to its simpler design and construction. Duplexes require more complex construction due to shared infrastructure and separate living spaces, leading to higher initial costs. However, the potential for rental income can make a duplex a better investment over time.

Which of the following is a potential long-term benefit of building a duplex over a single-family house?

A duplex can offer shared infrastructure and the potential for rental income, making it a cost-effective long-term investment. While initially more expensive, the ability to rent out one unit can offset costs and provide additional income, enhancing financial benefits over time.

What is a key factor that can make building a duplex more cost-effective than a single-family home?

Building a duplex is often more cost-effective due to shared structures such as walls and foundations, which reduce per-square-foot costs. While design complexity and separate utilities are factors, the economies of scale from shared resources primarily drive down costs compared to single-family homes.

Which factor can significantly increase the cost of land development due to legal and approval processes?

Zoning variances can lead to increased costs as they often require legal intervention to allow exceptions to existing zoning laws. This process can be lengthy and expensive, involving legal fees and additional approval times. Other factors like minimum lot sizes or building codes do not inherently involve legal processes that impact costs in the same way.

Which housing option generally provides more consistent rental income?

A duplex typically offers greater rental income potential because it consists of two separate units that can be leased out. This creates a steady revenue stream that can offset mortgage and maintenance costs. In contrast, a single-family home only provides one source of rental income.

How do maintenance and utility costs compare between a duplex and a single-family home?

Maintenance and utility costs are typically lower for a duplex due to shared expenses such as roofing and landscaping, and shared walls that reduce heating and cooling costs. In contrast, single-family homes require covering all these costs individually, often leading to higher out-of-pocket expenses.

Which of the following is considered a maintenance cost?

Maintenance costs include tasks such as HVAC system checkups, which are routine and preventative, whereas electricity, internet, and gas are utility costs that vary based on usage.

How can utility costs be controlled?

Utility costs can be controlled through energy-efficient practices such as using smart thermostats. Maintenance tasks like plumbing repairs and landscaping services do not directly influence utility expenses.

What is a typical range for monthly electricity costs?

The average monthly cost for electricity ranges from $100 to $200. This is influenced by seasonal changes and usage patterns, unlike maintenance tasks or other utility types like water.
