A single family house is the typical house that you see up and down the streets of almost every city. It is a stand-alone house where you would own the building and the land it sits upon. It may be a 4-bedroom, 2-story house in the suburbs or in the inner city.
In comparing a single family house to a townhouse or condo, there are significant advantages. The main advantage is that you own all the walls and structures, and you can do almost anything you want to it. If you want to paint it purple and yellow, you can. But having control of the entire property also means that you have to manage everything, including routine maintenance and long-term maintenance.
A detached house is one of the most common forms of home ownership. When you purchase a home, you are purchasing the land and any structures on it. The house can range in size from a one or two bedroom cottage to a large 5-bedroom, 3500 sq ft house to an entire estate. This is what lines most of the streets in the US.
