Since the erf allows for residential and small business use: Build, Live & Work
The big advantage is that the property is not restricted to purely residential use. A buyer could potentially purchase the erf and operate a small business from the property.
For example:
Build a modern house with a separate street-facing salon or office, while living at the property.
Design it with a residential section part of the building on the 1st floor and lease or use the ground floor for business. On this erf you are also permitted to build duplex flats.
Why this is valuable:
That gives the erf income-generating potential, which can make it more attractive than a comparable residential-only vacant erf.
