Overcapitalisation - Why Cost Does Not Equal Value?

If you are unaware of the real estate terminologies then you might be wondering what overcapitalisation is. Basically, overcapitalisation refers to an overspend on construction or renovation costs which means the actual cost of a construction/renovation of the property is superior to its real market value. Overcapitalisation is also considered as asset inflation. Confused? Let's make it simple. For instance, Mr A is planning to renovate his house by remodeling the bathrooms, basement and kitchen; upgrading the living room and bedrooms; adding a porch and swimming pool; installing vinyl siding, fencing front entrance and extending the garden. Mr A decides to use upper end expensive quality materials in the renovation. While doing so, he forgot to consider the real market value and quality of the houses in this area, which was lower than the value of his upgraded house. This is overcapitalisation.
