The results of tenders for rental of hawker stalls are published.
Thanks very much, Mike, I had not realized that, but have now googled and found some very useful information.
http://app.nea.gov.sg/cms/htdocs/article.asp?pid=977 seems a good page, as do others. It links "14 Nov 2008 List of successful tenderers" at
http://www.nea.gov.sg/cms/hd/HD_successful%20tenderers_%20Nov08.pdf There seems o be a very wide disparity, though, from sub $100 to over $2,000. It must be, as you say, location, probably coupled with the nature of the busienss.
The rest of what you said was useful too. It seems to be reasonable and consistent. So - a reasonable local income in return for a lot of hard work.
Thanks again for you rhelp.
