In as much as manufactured homes in Janesville will save you on costs, one thing that you have to do is keep an eye out for where the costs could shoot up. There are some common factors that will determine the true value of the manufactured home you are interested in. Land for example, usually holds more value than the manufactured home. It is in limited supply therefore it gains value over time, while the home could lose value at some point. Over time, land will surpass your manufactured home in value, so you have to factor this in keenly.
