This method of valuation is rarely used and is mostly reserved for very unique properties that do not come on the market very often. As such, it is not recommended for more common properties like houses.
Generally speaking, this involves working out the cost of the land as well as how much the properties on the land cost to be constructed. Construction costs include materials, manual labor, insurance, and specialist personnel like architects.
This is done by calculating costs at a rate per square metre and then making depreciation allowances.
It is not recommended to use this method for regular properties, and it is often only used by professionals when more common forms of valuation are not working.
It is not overly accurate or reliable, and there are better methods of calculating an accurate valuation.
Most estate agents will use the first three as they can commonly provide an accurate assessment of most properties. There will be variation between different market value opinions, but you can find a healthy middle ground to work with.
When calculating market value, it is important to consider capital appreciation as well. Seeing how a property’s value will increase in time is a key step in the process.
You should also be aware that market values include room for negotiation, so having a property valued at £200,000 does not necessarily mean you will sell the property for that price.
