The purchase of any property is an expensive process, either residential or commercial. In the case of a residential property, it is likely to be the single most investment made. It is therefore paramount to ensure that your investment is structurally sound, not only for your piece of mind, but also, in many cases, as large mortgages is being borrowed for the purpose of purchasing. It is therefore important that you protect the value of this by ensuring that there are no structural defects, which would obviously lower the value.
