The context you mention is different from the context of the question. In your case, the word "erf" is used as a description or a category heading. In the question, the word "erf" is used as a type noun in an address. The translation of the word will not necessarily be the same, therefore (granted, it often is, but I wouldn't be so sure in this particular case).

Compare:
1. The auditions will be held at Studio 5, Media Park.
2. The auditions will be held at:
Studio: 5
Building: Media Park
3. The auditions will be held at:
Room: Studio 5
Building: Media Park

In your example, the property would likely be referred to in legal documents as "SEC107" and not as "Erf SEC107", whereas in the question, the property is likely to be referred to in legal documents as "Erf 1410" (or "Stand 1410), and not as "1410".

The word erf is also used in normal speech in Afrikaans, but then it means yard/garden. The link provided by corbettb actually contains the answer, but he/she seems to have overlooked it :)

Having exhausted research, I did not find a satisfactory definition of the word "Erf". However, I came across it in a seemingly similar context -- the above one. Yes, my general text includes information about a bond holder from South Africa. It runs as follows:

Name of Bond holder: xxxx
Erf: SEC107 Green Acre, Terraces Strand
Amount: Rxxxxx
Title Deed Number: xxxx

Muhammad, is this a South African text? The price is in rand.
